A s president of DAC, I had the opportunity, with 2nd vice president
Daniel Robichaud, to attend the International Federation of Denturists Annual meeting in Helsinki, Finland in September. The IFD meeting was hosted by the Finnish Union of Denturists. The Finnish association, with President Juha-Pekka Marjoranta, vice president Ilkka and Tuula the chief administrative officer, hosted the world’s leaders of Denturism to a very well organized event. The DAC would like to thank the Finnish association for the gracious hospitality and hosting us in their beautiful country.
Representatives from nine countries were in attendance at this year’s meeting, giving status reports on what is occurring in their countries with regards to the profession.
The IFD is the global voice of Denturism and as such at these meetings, leaders are given the opportunity to exchange ideas, information, and finding solutions to deal with the challenges to improve and expand Denturism.
At our attendance of this international meeting it was evident that many issues which face one country are common to other countries.
In Canada we are truly the leaders of Denturism in the world, our scope of practice, government legislation, and education allow us to practice in a manner that all are envious of.
In many countries the opportunity to practice is not a viable option. Either government regulations do not allow for legislation or education is not available for training.
In most countries there is a catch-22 where educators are willing to teach the program, but there is no legislation to allow for the profession; so they are then teaching a course of study which is illegal and they could be prosecuted.
Governments will not usually proceed and legalize a profession that does not have education in place to train and support the profession. So how does Denturism grow in these other nations? These discussions with the representatives of the other members of the IFD make us aware of the complex issues that occur in these countries trying to develop the profession.
Even if the local Denturist association is able to approach government it is a slow, costly process. In most cases before legislation can be enacted,
the government, minister of health, or supporters of the bill change, whereby the process stops. The associations then have to re-aquaint themselves with the new government ministers, lobbyists and start the process again.
The global economic crisis has put pressure on government health services to reform the types of services available and provided to the public. The public, due to the increasing aging population, is looking for efficient access to denture health care without compromising the standard of care. This can be accomplished with the introduction of Denturism to these countries.
This may only be achieved with the support, direction and input from nations like Canada, and others, who have education, legislation and a defined scope of practice in place.
The Canadian Denturist model and perspective have always been very positively accepted by all nations at the IFD meetings. We must continue to contribute and provide opportunities to assist these countries in their bid to legalize Denturism.
We must in Canada, with our own legislation, scope of practice and educational facilities, remain committed to the betterment of our profession. When one sees the struggles that fellow Denturists from around the world have to contend with, it makes us truly proud of the system that has been developed as a role model here in Canada.
We must continue to be aware of the international development of our profession. We should be ready, willing, and able to assist the IFD in being the global voice of Denturism, to be proud of our accomplishments and continue to work together to promote our profession.

Le mOt du PRésidentmichael C. vout, dd
affiliations et liens internationaux
À titre de président de l’ADC, j’ai eu l’occasion, en compagnie du
2e vice-président Daniel Robichaud, de participer à la réunion annuelle de l’International Federation of Denturists, qui a eu lieu à Helsinki, en Finlande, en septembre dernier. L’hôte de cette réunion était l’Union des denturologistes finlandais. L’association finlandaise, dont la présidence est assurée par Juha-Pekka Marjoranta, la vice-présidence par Ilkka et la direction administrative par Tuula, a offert aux leaders du milieu de la denturologie une rencontre très bien organisée. L’ADC souhaite remercier l’association finlandaise pour sa chaleureuse hospitalité et pour avoir accepté de nous accueillir dans son beau pays.
Cette année, des représentants de neuf pays se sont déplacés pour la rencontre; ils ont fait état de la situation dans leur pays respectif en ce qui a trait à notre profession.
L’IFD est l’instance qui chapeaute la denturologie à l’échelle mondiale. Par conséquent, à ses réunions, les leaders ont l’occasion d’échanger des idées et de l’information ainsi que de chercher des solutions afin de relever les défis qui se présentent et de faire avancer la denturologie.
Notre présence à cette rencontre internationale nous a permis de constater que bon nombre de difficultés que vivent certains pays sont communes à d’autres pays.
Au Canada, nous sommes vraiment à l’avant-garde de la denturologie dans le monde. En effet, notre champ d’exercice, la législation gouvernementale et la formation nous permettent d’exercer dans
des conditions qui font l’envie de tous.Dans de nombreux pays, l’exercice de
la profession n’est pas une option viable. Soit la réglementation gouvernementale ne permet pas la législation, soit il n’y a pas de formation dans le domaine.
Dans la plupart des pays, il y a une impasse : on trouve des formateurs disposés à fournir l’enseignement, mais il n’y a pas de législation autorisant la profession. Ils donnent donc un programme d’étude qui est illégal et s’exposent à des poursuites.
Habituellement, les gouvernements ne légalisent pas une profession pour laquelle il n’existe pas de formation ni de structure pour soutenir la profession. Alors, comment la denturologie évolue-t-elle dans ces autres pays? Les discussions avec les représentants des autres membres de l’IFD nous font prendre conscience des difficultés complexes que doivent résoudre ces pays qui tentent d’y instaurer notre profession.
Même si l’association locale de denturologistes est en mesure d’approcher les instances gouvernementales, c’est un processus lent et coûteux. Dans la plupart des cas, avant que la législation ne puisse être adoptée, le gouvernement, le ministre de la santé ou les défenseurs de la cause changent et donc le processus s’interrompt. Les associations doivent alors de nouveau se familiariser avec les nouveaux ministres et lobbyistes, et recommencer le processus.
La crise économique mondiale a eu pour effet d’exercer des pressions sur les services de santé gouvernementaux afin qu’ils procèdent à une réforme des types de services accessibles au public.
Le public, en raison du vieillissement accru de la population, cherche à obtenir un accès efficace aux soins de santé dentaire sans compromettre la qualité des soins. Cela peut se faire par l’introduction de la denturologie dans ces pays.
Or, cela ne peut être accompli sans l’appui, l’orientation et la contribution de nations comme le Canada, et d’autres aussi, où la formation, la législation et un champ de pratique défini existent.
Le modèle canadien et les perspectives en denturologie dans notre pays ont toujours été très favorablement acceptés par toutes les nations présentes aux réunions de l’IFD. Nous devons continuer de contribuer aux échanges et de fournir des occasions d’aider ces pays dans leur démarche en vue de légaliser la denturologie.
Au Canada, où nous pouvons compter sur une législation, un champ d’exercice et des établissements de formation, nous devons continuer d’être déterminés à rehausser notre profession. Lorsqu’on pense aux luttes que doivent mener nos confrères denturologistes partout dans le monde, cela nous rend vraiment fiers du système qui a été mis en place et qui sert de modèle ici au Canada.
Nous devons continuer d’être conscients de l’évolution de notre profession à l’échelle internationale. Nous devons être prêts à aider l’IFD, désireux et capables de le faire, afin que cette association défende les intérêts de la denturologie dans le monde. Nous devons être fiers de nos réalisations et continuer de travailler ensemble à promouvoir notre profession.

editOR’s messageHussein amery, m.sc., Psy. d., dd, FCad
In 1948 the World Health Organization defined “health” with a very forward-
looking statement and definition. They said it was “a complete state of physical, mental and social well-being and not merely the absence of disease or infirmity,” (WHO,1948).
This definition is at the core of 21st century healthcare and health psychology as the essence of today’s conception of health. Rather than defining health as the absence of illness, health is recognized as an achievement involving the balance between physical, mental and social well-being. This is further evidenced by major health authorities across the country using “wellness” in their department titles, for example: Alberta Health and Wellness
Health and wellness
and Ontario Health and Wellness Centre.
Wellness has now been used to be synonymous to an optimum state of health.
As healthcare professionals, we must be equally in touch with the all-encompassing aspects of health and illness across the lifespan of our clients. We can be effective as practitioners by focusing on health promotion and maintenance, which includes not only oral health for our clients but issues as general as developing overall good health
habits, promotion of exercise and
proper diet.The second
most important aspect is prevention and treatment of
illness. In our case, preventive
education and regular oral care
regimen are par for the course for our clients. The etiology of health, illness and dysfunction such as smoking, alcoholism, exercise and even ways of coping with stress are important markers in our pre-treatment assessment and planning as well.
Healthcare ministers and their staff from coast to coast to coast now focus, analyze, and attempt to improve the healthcare system and the formulation of healthcare policy based upon these factors. They study the impact of health institutions and health professionals such as us on clients’ behaviour and develop recommendations for improving healthcare and healthcare benefits.
So the next time you are invited to participate in healthcare forums or as part of your professional organization’s fee guide committee, please do. This collaborative approach represents the educational, scientific and professional contributions to the promotion and maintenance of health, the prevention and treatment of illness, related dysfunctions and the eventual improvement of the health care system and delivery of services as well as the formation of new healthcare policy.
“As healthcare professionals, we must be equally in touch with the all-encompassing
aspects of health and illness across the lifespan of our clients.”

What are the duties of an executor?
Choosing an executor is an important and complex decision.
A trust company, friend, or family member, can act as your executor, and may have the following responsibilities:• Distribution of investment assets
according to your will.• Locating any named beneficiary of
your investments. • Where applicable, make transfers in
kind to beneficiaries.• Provision of money from your savings
or investments for surviving family members (there may be a short delay if the estate is probated).
• Examining life insurance policies and collecting death benefits or confirming beneficiary payments are made.
• Evaluating investments and collecting income payments.
• Selling stock and/or fund assets, where necessary, to pay taxes, debts, legacies and bequests, and closing accounts where applicable. When deciding to sell a particular investment, the executor must weigh economic conditions and tax consequences.
• Purchasing an RRSP contribution to a spousal RRSP for a tax break.
• Filing final tax returns.• Paying any income tax due, including
income reported as capital gains on equity investments; dividends; and interest earned.
• Getting a clearance certificate from Canada Revenue Agency (CRA).
• Consulting professionals such as trustees, accountants, lawyers, or financial advisors regarding the settling of large estates and/or significant
investments, and paying them for their services.
• If an investment portfolio exceeds a certain limit, letters probate may be required by a financial institution to allow release or sale of investments. (This normally will exclude monies registered in an RRSP or RRIF where the surviving spouse is designated as the beneficiary.)
Note: Use the services of a professional as an executor, such as an accountant or lawyer where there are many diverse types of investments in your estate. Do not name an executor without his or her consent. It is not clear in most provinces if an executor may purchase investments unless expressly stated in the will.

PRaCtiCe managementJanice Wheeler, President, The Art of Management Inc.
the dream team
Having worked with more than 1,100 Canadian healthcare professionals
over the past 21 years, we’ve observed that most of them do a fairly decent job of hiring the right staff but they THINK they haven’t – simply because they’re not coaching them into the dream team.
While there is neither such thing as a perfect boss, nor a perfect staff member, there are ways to coach the team into the best possible performance.
Here are 10 suggestions:1. Know exactly what YOUR practice
goals are. And we’re not just talking dollars and cents here. YOU must determine what you want from the practice: what hours, what type of patients you want, what level of care and service to provide. And yes, what level of profitability you want to achieve.
2. Set specific POLICY for your practice. Define the guidelines for achieving your goals: what kind of payment plans are you going to allow patients; are you going to accept assignment of insurance; what is your fee guide and are you going to stick to it; cancellation policy and how are you going to enforce it; recall system and how the staff are to accomplish this; general staff guidelines, such as vacation, illness, uniforms, confidentiality of patient information, etc.
3. Now you need some PLANS to achieve those goals, such as marketing plan (internal and external), bonus system for your staff, etc.
4. A staff meeting once a week is a great place to review the statistics and progress of the practice toward your goals and then set up game plans, quotas to be met and targets to be accomplished
in the next week. Well done staff meetings result in increased efficiency and productivity through coordination of staff efforts.
5. Daily morning conferences coordinate the various aspects of the practice for the day as a team. Include discussions of any special needs of patients coming in that day.
6. Acknowledge your staff. Thank your team players for being there and doing their jobs effectively.
7. When and how to correct a staff member is a touchy topic. Sometimes you feel like losing your cool when a staff member does something wrong in front of a patient, BUT DON’T! Meet later privately, and discuss the incident and work out how to prevent it from recurring. Document it for the staff member’s personnel file. The rule of thumb is: correct in PRIVATE and compliment in PUBLIC.
8. Now we get to the BONUS system. Incentive plans are an accepted method of acknowledging productivity
and, if well designed, will enhance the viability of the practice.
9. Lead by example. Be positive about how the practice is doing; don’t get negative when things appear to be going in the wrong direction. As the leader of the practice, you are expected to set a positive tone. Present the staff with a positive plan of action or get their input on one.
10. Give your orders clearly and in writing and keep a copy for yourself to follow up on at a specified time.
11. Continuing education for both the denturist and staff helps keep everyone at the peak of their game.
Of course there are hundreds of other points to becoming the world’s best boss, but start with the above.

Last May, at the national convention in Whistler, my wife Mary and I started a
fund to help Debbie and Greg MacDonald. Mr.
MacDonald is a denturist from Nova Scotia and
frequent attendee at national meetings representing his province. This
fund was established to help offset some of the costs they would encounter following his wife’s accident in Vancouver just prior to the conference. Debbie MacDonald had been
hospitalized following a bicycling accident with a serious head injury. She remained comatose in hospital throughout the conference for about a week. She regained consciousness but remained hospitalized. She was released after about four weeks when it was deemed to be safe to travel home and to continue her long journey of rehabilitation back to a normal life with her family, friends and community.
I announced to the convention, that Mary Hicks and I were donating $250 to the MacDonalds to help them offset the costs of their extended stay Vancouver. I asked other denturists and sponsors if they felt inclined to donate any monies at all, we would gather, administrate, and deliver it to the
MacDonalds. After we returned to Winnipeg, Mary and I extended the invitation to donate to the rest of my Canadian colleagues.
What transpired throughout the month of June is inspirational. All told, we as a national organization, individual members and along with some corporate donations, managed to raise $9420. Donations came in from across our great nation and we forwarded to Greg and Debbie immediately.
Collecting these monies and passing it on to the MacDonalds pales in comparison to the task ahead of Debbie as she tries to climb back from her accident. Brain injuries can take months to heal and for the patient to regain some form of normalcy. Debbie now faces a monumental challenge to regain her health, get back to her job, and enjoy her family and friends to the fullest. Hopefully the donations we make can somehow ease the journey for the MacDonalds in some way. Good luck and a speedy recovery to Debbie was a common notion from all donors! And to Greg and family, our thoughts go out to them as they face many challenges aiding Debbie.
A heartfelt “thank you” goes out to all those who took a little time to make a donation. Also, thank you to Mary Hicks for “volunteering” to administrate the donations.
Finally, to the Canadian denturist fraternity, you should be proud, we truly are family.
Sincerely in denturism,David L. Hicks, Past President, DAC

abstraCtAim of the study: To investigate the effect of the Ultrasuction system on the retention of mandibular complete dentures. Material and methods: This study was conducted on seven completely edentulous patients. Each patient received a maxillary and two mandibular complete dentures, a conventional (set I) and an Ultrasuction retained denture (set II). Patients were left to function with each denture set for a period of one month during which they were recalled to test the denture retention at time of denture delivery, one, two and four weeks later. In the retention test a specially designed retention testing device was used to pull the dentures from their geographic centers. The collected records were statistically analyzed using the paired t test. Results: The mean retention values for set I dentures were 157.96 ± 29.75, 165.57 ±29.21, 170.77 ±29.64 and 175.26 ±29.03 at the baseline and after one, two and four weeks respectively, while for set II dentures the values were 187.80 ±28.52, 196.17 ±29.18, 201.51 ±28.82, 206.93 ±28.56 at the baseline and after one, two and four weeks, respectively. Statistical analysis of these data revealed a significant increase in the retention after the application of the Ultrasuction system and a significant increase in the retention of both sets of dentures by time (p≤ 0.05). Conclusions: The Ultrasuction system increases the retention of mandibular complete dentures. However, further
long-term prospective clinical studies are recommended to investigate the biological effect of the system on the supporting tissues. Keywords: Retention, mandibular complete denture, Ultrasuction device
introDuCtionAlthough most patients express satisfaction with their conventional maxillary complete dentures, many struggle with the comfort and function of their mandibular complete dentures (1,2). This could be attributed to their smaller denture bearing area, unfavorable distribution of occlusal forces resulting in increased rate of bone resorption, decreased stability and retention which in turn result in pain and patients’ discomfort (3). Besides, the seal area in the mandibular denture was not as readily located as in the maxillary denture and showed considerable movement during the ordinary functions of the mouth (4, 5).
The use of endosseous dental implants to assist in the support, stability, and retention of removable prostheses is considered an effective treatment modality for edentulous patients (6, 7). However, there may be situations when it is impossible to provide implants or bone grafts on ground of medical, surgical or costs factors, especially in elderly patients (8). In such cases a proper understanding, recognition and incorporation of certain mechanical, biological, physical and aiding factors becomes necessary to ensure optimal mandibular complete denture retention (9).
Recently, a variety of retentive aids have been introduced to improve denture retention, the most common of which includes the use of soft liners and flexible denture bases to engage undercuts, denture adhesives, multiple suction cups and Ultrasuction devices.
Denture adhesives merely reduce the amount of lateral movements that occur while dentures are in contact with basal tissues (10). This benefit can mislead a patient into ignoring his or her need for professional help when dentures actually become ill-fitting. Besides, patient’s response to the use of these materials is not totally positive because of the grainy or gritty texture of powder, the sensation of semi-dissolved adhesive materials that escape beneath the denture (11), the difficulties encountered in removing the adhesive from the denture and the oral tissues, the accompanying increase in the vertical dimension of occlusion (12) and the cost of the material. Denture adhesive products are frequently regarded as an obstacle to the dentist’s ability to evaluate accurately the health of a patient’s oral tissues (13,14) and the true character of denture adaptation (15). Relining of dentures with soft liners is, therefore, preferred over using a denture adhesive (16). Unsealed soft liners, however, showed increased colonization of Candida compared with those sealed with an acrylic varnish, implying that porosity and not the potential nature of soft liners may result in the amplified yeast loads (17).

of a denture were resurrected since their late introduction in 1885 (18,19). Their recent use in patients unable or unwilling to undergo surgery to improve their denture foundation has shown a successful, economic and noninvasive way for enhancing denture retention. Because the amount of retention provided by suction cup adhesion is proportionate to the area covered by the denture, mandibular dentures are subjected to a lower magnitude of adhesive retentive forces, a problem better solved by the Ultrasuction system. The latter is a patented system that holds maxillary and/or mandibular dentures in place using suction chamber and a mounted valve that comprises a tiny unidirectional device imbedded into the denture base. As the patient bites firmly, the air trapped between the mucosa and the denture is expelled through the device, via two air passages. The lower pressure obtained beneath the denture tends to exert a pull and helps secure the denture against the ridge (20). In an attempt to reveal the effect of this system on enhancing the mandibular complete denture retention this study was conducted.
Material and methodsThis study was carried out on seven completely edentulous co-operative patients selected from the Prosthodontic Department, Faculty of Oral and Dental Medicine, Cairo University. The age of the selected patients ranged from 45-65 years and all of them were selected to be free from systemic and oral diseases, especially those that might affect the retention of the denture as neuromuscular disorders, diabetes mellitus and/or xerostomia. Their residual ridges were covered by firm healthy mucosa and exhibited no unilateral or bilateral undercuts to eliminate the effect of the latter on the retention and to facilitate the performance of the retention test. Patients also had an Angle class I maxillomandibular relationship, normal tongue size and were free from any temporomandibular joint troubles. Before including the selected patients in the study an informed consent was obtained from each one of them because hyperplasia of the soft tissues covering the residual ridges was expected to occur after fitting the Ultrasuction system.
For each patient one maxillary and two mandibular complete dentures were constructed, namely set I and II dentures.1. set I: It was represented by the
conventional mandibular dentures.2. set II: It was represented by the
Ultrasuction retained mandibular dentures.
Set I dentures were first delivered to the patients, who were left to function with these dentures for a period of one month during which they were recalled for alleviating any complaint, checking occlusion and testing denture retention. Set II dentures, however, were delivered after a resting period of about two weeks to one month during which the patients were left completely without the dentures. This period allowed for tissue rebound. Patients were then allowed to function with the new set of dentures for the same period as Set I, namely one month.
i: Construction of set i mandibular denturesThis set of dentures was constructed in the conventional way except that the mandibular secondary impression made

in rubber base* was boxed and poured in dental stone** three times to obtain three master casts without affecting the accuracy of the poured impression (21, 22). Boxing was an essential step to preserve the depth and width of the borders which had to be reproduced in set II. On the first two master casts namely cast (a and b) the first and the second set of dentures were processed, whereas the third cast namely cast (c) was used in determining the geographic center of the dentures and in checking that the extension of both sets (I and II) of dentures was not changed or jeopardized by excessive finishing and polishing procedures. Changes in the extension carried out during the delivery visit of set (I) dentures were transferred to cast (c) by an indelible pencil so that they could be reproduced in set (II) dentures.
Since the maxillary cast of each patient was mounted on a semiadjustable articulator*** using a maxillary face bow**** record, a face bow index was obtained after finishing the try in stage of set I dentures to aid in remounting the finished and polished maxillary denture.
ii: Construction of set ii mandibular denturesIn this set of dentures, the retention was assisted by an Ultrasuction system. The latter is supplied in a kit consisting of; two ultra suction valves, a specially designed profiled bar (spacer) used to create a
suction chamber at the ridge level, two processing caps, service key and spare diaphragms (Fig. 1).
The specially designed profile bar was stabilized on the master cast (b) using 2-3 drops of cyanoacrylate (Fig. 2). It stopped about 1 cm short of the end of the denture. After applying adequate amount of separating medium on both the cast and the bar, a mix of self cured acrylic resin was adapted on the cast to construct the trial denture base. Baseplate wax was then used to form the occlusion rim. The resulting occlusion block was used to record the centric and protrusive relations against the finished maxillary complete denture, which was remounted by the face bow index.
After processing of set II dentures, the bar was removed. Particular attention was given to prevent damage to the walls of the created suction chamber. In the lingual flange at the premolar-first molar area, two cavities were prepared in which the valves were lodged. The graded end of the service key was used to guide the width and depth of the valve (Fig. 3).
A processing cap was placed in each valve to protect the core from being filled with the self cured acrylic resin that was used to fix the valves (Fig. 4). The processing caps were then removed after polishing. Using a fissure bur (1mm in diameter) a communication channel between the valve and the high point of the suction chamber was created. A plastic
diaphragm was placed in each valve and the perforated cover was closed with the key provided.
Once the patient received set II denture, he was instructed to run water through the visible orifices of the suction chamber on a daily basis, otherwise the valves would be blocked and would lose their efficiency.
iii: Determining the geographic center of the lower denturesWhen both sets were finished, the dentures were prepared for the retention tests. It has been documented that the measurement of complete denture retention was best attempted by pulling the denture from its geographic center (23). Hence, it was essential to locate this center for both sets of dentures. This procedure was carried out on cast (c) as explained below.
Three lines were drawn on the cast and extended to the cast base to aid in determining the geographic center of the lower denture, point (a) as seen in Fig. 5. At this point a trough was drilled in the cast base by the aid of a surgical round bur. The bur was then maintained in the trough leaving 20 mm of it projecting from the cast. This was the most appropriate length from which the application of force took place without endangering the upper jaw or being interfered by the tongue. The denture was then placed on cast (c) and was prepared for the retention test as described below.

its midline and two posteriorly where line (4) (Fig. 5) passed through them. Three metallic wires 18 gauge in diameter, as advocated by Burns et al (24), were engaged by the three lingual brackets and extended upwards to meet in the geographic center of the denture, which was easily identified by the surgical bur projecting from the cast base. A metallic loop was then used to join the three wires on the top of the bur.
V: Measuring the retention of set i and ii lower denturesThe retention measurement test was performed for each set of dentures at time of insertion, one week, two weeks and one month after delivery. During the retention test each patient was asked to keep his chin firmly on a chin support and to wear the upper denture to prevent palatal injury while pulling off the denture. The test began only after the patient was allowed to bite on his dentures to expel any air trapped beneath the denture base.
The retention was measured by a specially designed retention testing device (Fig. 6). The device is digital and can apply forces in upward and downward directions. It has a minimum reading of 20 and a maximum reading of 5000 grams with a good to a very good (0.778-0.998) reliability. It consists of a metallic probe connected to a base by an electric wire. The metallic probe constitutes the part of the device that applies the force. The base, on the other hand, has a digital screen which gives positive and negative readings according to the direction of force application. The device applied a vertical pull-off load on the metallic loop joining the wires. Values at which the denture was dislodged were recorded.
The pull-off procedure was repeated 10 times to obtain 10 records for each, the mean of which was calculated.
Vi: statistical analysis of the resultsThe recorded mean values were tabulated and statistically analyzed using SPSS 16.0® (Statistical Package for Scientific Studies) for Windows. Paired t-test was used to compare between the mean retention values obtained for each set of dentures at the different follow up visits and to compare the retention values of both denture sets. Results were considered significant at p≤ 0.05.
resultsi. Clinical observationsAll patients were satisfied with both sets of dentures. However, they explained that the retention was surely enhanced with the Ultrasuction system. Their main complaint of this system seemed to be related to the difficult cleansability of the

orifices. By examination it was found that three out of seven patients showed slight hyperplasia of the ridge mucosa after four weeks of inserting set II dentures.
ii. statistical findingsThe comparison between the mean retention values of set I and II dentures revealed a statistically significant increase (p≤ 0.05) in the retention after the application of the Ultrasuction system at all follow up visits (0, 1, 2, 4 weeks) (Table 1). On the other hand, studying the effect of time on the mean retention values obtained for both sets of dentures (I and II) revealed a statistically significant increase in the retention by time (p≤ 0.05) (Table 2).
DisCussionIt is well known that maxillary dentures are retained by interfacial surface tension, good denture base adaptation, border seal and other important physical, mechanical and psychological factors. The same applies for mandibular dentures, but the smaller supporting surface area and the pronounced musculature in the lower jaw, reduce the retentive capacity of these dentures, causing their displacement (3). Although the multi-suction cup lined denture, resurrected by Dr. Jermyn in 1963, offered a successful, economic and noninvasive way for enhancing denture retention, they sometimes stand helpless in overcoming problems of reduced
supporting surface area as in mandibular dentures. In these situations Ultrasuction dentures appear to offer a better solution. Their retentive capacity in comparison to conventional mandibular dentures has been positively demonstrated in this study not only via the patients’ comments, but also via the retention test, which showed a significant improvement in the denture retention after the application of the Ultrasuction system. Mony Paz, the system inventor, explains that once the patient bites firmly, the valves incorporated in the system allows for expelling the air from beneath the denture base and the gingival tissues penetrate the suction chamber. Simultaneously, the diaphragm

prevents the reintroduction of the expelled air. The pressure difference, that is, the lower pressure beneath the denture, exerts a pull and seals off the alveolar ridge periphery, creating better fit and high resistance to denture dislodgement (12). Thus, the increase in the retention of set II dentures could be mainly attributed to the atmospheric pressure effect that has been long time ago documented in dental literature (25, 26). This effect seems to be only active, if the denture has an effective seal around its border. Unfortunately, the negative pressure effect created by the valves of the system results in hyperplasia of the tissues covering the ridge (19). The system is, therefore, never intended to make up for under-extended or inaccurate impressions, a condition that requires further investigations to evaluate biological long-term effect of the system on the health of the tissues.
Statistical analysis also revealed a time dependent increase in the denture retention for both sets, namely set I and II. This could be attributed to the adaptability of the oral mucosa to the new denture regardless of the differences between both sets. Murray and Darvell (27) pointed out that muscle control and patient’s tolerance often has an amazing influence on the denture retention, because of the adaptability of the oral mucosa and the muscles of the lips, tongue and cheeks as well as patient’s tolerance.
ConClusionsThe Ultrasuction system increases the retention of mandibular complete dentures. However, further long-term prospective clinical studies are recommended to investigate the biological effect of the system on the supporting tissues.

By Dr. Gerry Ross, DDS and Alana Ross, BScH
Dental treatments have changed dramatically in the last few decades. At one time, dentures were often ill fitting and could cause a significant change in a person’s lifestyle. Little could be done to decrease the pain and speed the healing of denture sores, impressions were bulky and took a long time to set, and were often ruined by patients gagging. Implants were virtually obsolete so elderly patients had little options for proper fitting dentures and required lots of adhesive to hold them in.
Dental tools have improved dramatically. Dental practitioners now have a number of modalities on hand that improve clinical outcomes and patient comfort. One of the more unknown therapeutic tools is low level laser therapy (LLLT). Never heard of it? This article will explain this therapy and how it can be used in your practice and life.
In the 1960s, Theodore Maiman and Endre Mester were both exploring the use of light as a therapeutic tool. Theodore Maiman developed the first working Ruby Low Level Laser, a feat which helped earn him two Nobel Prize nominations. A few years later, Dr. Endre Mester became interested in LLLT and began conducting experiments of his own. He was initially interested in whether lasers could cause cancer in mice. He shaved the bellies of mice, and irradiated one group using the other group as a control. This study demonstrated two important findings: the first was that lasers didn’t cause cancers; the second and much more unexpected finding was that the hair grew back quicker on the irradiated mice. Interested by these results, he conducted another series of experiments investigating the therapeutic nature of the laser devices and demonstrated a number of things, including that laser therapy stimulated wound healing. It was from these initial experiments with laser therapy that the term biostimulation was coined and some real interest in LLLT began to take place.
Since that initial experiment done by Dr. Mester’s lab, thousands of studies have been conducted to determine which wavelength, power, energy density and dose should be used in various clinical situations. Despite the large amount of research supporting the technology, laser therapy is still relatively unknown in mainstream medicine. Laser therapy has been used in Europe for decades; however, it’s acceptance in North America has been slow, a result of tight (and somewhat biased) regulatory restrictions and a previous lack of double-blind, placebo-controlled studies to justify or explain how laser therapy works. In recent years, the quality of research has improved dramatically and is now being published in distinguished journals such as PAIN, Nature and most recently, The Lancet.
Historically, light has been seen as therapeutically advantageous. Early in the 20th century, hospitals recognized the healing power of light and would often wheel patient beds to the roof of hospitals to encourage patient well being and
healing. Presently, millions of people flock south during the winter months or use UV light therapy to combat Seasonal Affective Disorder (SAD), a depression that strikes many when sunlight is at a minimum. One of the best examples of light is seen in the process of photosynthesis, where plants utilize and convert light energy into glucose for fuel.
Low level laser therapy (LLLT), also referred to as phototherapy or photobiostimulation, uses light energy from lasers or light emitting diodes (LEDs) to elicit cellular and biological responses in the body. Light photons work on various cell processes to stimulate the release of cellular energy, which can be used to facilitate the restoration of normal cell morphology and function.
Figure 1: Primary mechanisms of laser therapy
Some of the clinical effects of laser therapy are included in the table below:
The therapeutic effects of laser therapy extend to a number of healthcare fields, including veterinary, medicine, physiotherapy, chiropractic medicine, neurology and even as a treatment option for various tumours. We will start by focusing on the applications for a dental practitioner, and then touch on how is can be used in various healthcare fields.

liGHtS AnD lASeRS in DentiStRy The use of lasers and lights isn’t new to most dental practitioners. Many curing lights use LEDs to cure composites by activating composites via a photochemical effect. Surgical lasers are common in dental practices and use a photothermal effect for ablation of soft tissue and enamel. Low level lasers don’t cut tissue but instead penetrate into the mitochondria of the cell and elicit a cellular response.
LLLT can be a huge asset to dentists and their patients. Below is an example of the clinical applications in a general dentist or denture clinic.
nAuSeA AnD GAGGinGMany patients have a sensitive gag reflex making dental work very stressful for both the patient and dentist. Application of the laser to the P6 acupuncture point of the wrist will decrease the gagging and nausea sensations many patients feel during dental treatments, impressions and x-rays. The P6 acupuncture point is one of a triad of points that calms your parasympathetic nervous system (Figure 3). Application of these points is also effective for patients who are anxious and nervous. A pedodontist in Boston regularly has patients referred to him for general anaesthetic because of their gagging. Currently he reports that he is now able to perform 90% of those procedures with the laser alone for controlling the gagging reflex.
imPlAntS Laser irradiation during the preparation and placement of implants will decrease the pain and inflammation of the surgical procedure and improve the integration of the implant into the bone. Many studies investigating the effect of LLLT during implant placement have demonstrated faster integration with a better quality of bone and a decrease in pain at the time of placement. 1
FAciAl PAin/muScle tRiSmuSLaser therapy can be used very effectively for facial pain treatment, either acute or chronic. A major complaint a lot of patients have after long dental appointments is facial pain and muscle tension. Application of the laser to the masseter muscle after the appointment will reduce or eliminate the muscle trismus and joint pain. In chronic TMJ cases, laser therapy can be used in conjunction with other therapeutic tools to reduce the pain and muscle tension, while stimulating healing within the joint. It is commonly used in cases with myopathic pain, arthritis and intracapsular problems. 2

cASe StuDy: imPlAntSA patient presented with a cracked tooth that had abscessed over time. The patient was sent to an oral surgeon, who sectioned the tooth and removed some bone. The laser was applied immediately after extraction, both in the socket and along the suture line. The oral surgeon offered to prescribe Percocet for pain, but the patient declined and experienced no pain. Over the next three weeks, the laser was applied two times per week around the extraction site. Three months later, the patient returned to have an implant placed. At the time of surgery, the surgeon commented on the quality of bone at site. LLLT was applied both after the site was prepared and after the implant was placed, to the buccal and lingual surface. The patient experienced no post-operative pain and took no pain medications.
Scientific support: A study investigating the stimulation of human osteoblasts in vitro found a significant increase (25%) in the number of osteoblast cells following three seconds of irradiation. Further, there was a 40% and 38% increase in optical density following 24 and 48 hours, respectively. The authors concluded that LLLT demonstrated a significant enhancement in the differentiation of human osteoblast cells.
Figure 4: laser application after implant placement
cASe StuDy: FAciAl PAinA 60-year-old man went to his denturist to have impressions taken for his new denture. He told his practitioner he was really experiencing a lot of pain every time he opened his mouth and was only able to open 25mm. A cluster of high-powered LEDS was applied to his masseter muscle and covering the joint. The gentleman’s opening improved to 45mm and the impressions were taken without discomfort to the jaw.
Scientific support: A study by Kubota et al postulated that the pain mechanisms of LILT in facial pain may be a result of “LLLT-mediated improved microcirculation in the temporal and masseter muscles, thereby relaxing and softening affected muscles and relieving pain.”

SoFt tiSSue leSionS Soft tissue lesions, such as denture sores, herpes lesions, angular chelitis and oral mucositis, respond very well to LLLT. Research has indicated that LLLT can prevent cold sores from erupting if treated in the prodromal stage (when the tingling starts) and speed the healing in cases where the sore has erupted. Laser therapy is commonly used during chemotherapy and stem cell therapy to either prevent oral mucositis from developing or effectively treat it in the case that it does occur. 3
Figure 5: Application to styloid joint
otHeR APPlicAtionSThe clinical applications of laser therapy reach far beyond dentistry. Some of the research that is currently being conducted using laser therapy is astounding. In Israel, researchers are studying the effect of using a combination of laser therapy and stem cells for the regeneration of damaged spinal cords; human clinical trials being conducted in Peru are studying the use of laser therapy for the treatment of breast and prostate tumours, with some very promising results. Multiple labs in the USA are experimenting with different wavelengths of lasers for the treatment of Parkinson’s disease. In Toronto, a Laser Rehabilitation Centre is taking patients with diabetic ulcers who are scheduled for limb amputations and healing 90% of the wounds. These are just examples of the extraordinary results seen with lasers.
It is hard to imagine that something as basic as light can be used to speed wound healing, decrease pain, relieve inflammation and decrease muscle trismus; however, for decades lasers have demonstrated to do all these things and more. It is not a magic wand, it will not cure all conditions and work in every situation, but it is a therapeutic alternative or adjunct that should be investigated as another tool for a dental practice. With the number of pharmaceutical drugs on the market today that carry detrimental side effects, it makes sense to use LLLT that has no side effects and has substantial and positive research supporting it. Laser therapy requires a paradigm shift and takes practitioners out of their normal way of treating patients and conditions. The dental team now has the ability to treat pain and inflammation immediately after it has been caused, and do so without using pharmaceuticals.
Light therapy uses the body’s own natural resources to provide pain relief, muscle relaxation, wound healing and nerve regeneration. Low level laser therapy offers the opportunity to better manage treatments that are often deemed painful by patients while enhancing their practice with improved clinical treatments and patient comfort.
cASe StuDy: DentuRe SoReSA 58-year old woman presents at her denturists office with a large sore on her lower gum. She tells her denturist that she has been leaving her dentures out for a few hours every day because the sore was incredibly painful. Her denture was adjusted and the laser was applied to the denture sore. The next day, the patient called the denturist to tell him that the sore was almost healed, the pain was gone and she was able to wear the denture without issue.
Scientific support: Marei et al investigated the use of laser compared with conventional methods in the treatment of mucosal lesions and found a positive effect of therapeutic laser treatment on both soft tissue and bone with subsequent improvement of denture foundation after treatment of denture-induced mucosal lesions.
Figure 6: laser therapy for soft tissue lesions
cASe StuDy: cARPAl tunnel SynDRomeA dental hygienist started experiencing problems with her wrists and hands. She frequently had to stop while treat her patients and massage her wrists and fingers. She started experiencing tingling and aching regularly throughout the day and was forced to start taking regular anti-inflammatories frequently, which upset her stomach. The laser was applied to her cervical spine and over the median nerve three times a day for two weeks. The pain and tingling subsided and the hygienist was able to stop taking anti-inflammatories. She currently applies the laser to the cervical spine once a week as a preventative measure and no longer experiences any painful symptoms.
Scientific support: Wong et al investigated laser therapy for the treatment of Carpal Tunnel Syndrome and found that in all 35 patients, pain, numbness and tingling of the hands disappeared or subsided significantly and there was decreased tenderness at the involved spinous processes. This study focused the irradiation to the cervical spine as opposed to the wrists and hands.

Clinically, LLLT can be used with ease in a dental office. Because laser therapy is non-invasive and has no significant side effects, the treatments can frequently be done by the auxiliary staff and easily integrated into the practice.

Pack mentality
W hen my son was two years old, we got a Samoyed puppy, and for
the next 18 months they were the best of friends. Then the dog changed. Suddenly she started growling at my son and biting him. At first I thought that maybe he was pulling her tail or something else that was irritating her, but that wasn’t it.
My dog had become an adult and instinct kicked in. She became concerned with her place in the pack hierarchy. I learned that our family was her pack, that I was alpha-dog, and that she had no intention of being at the bottom of the pecking order. That meant someone had to be beneath her and the easiest choice was my toddler.
Through training and discipline we got the biting to stop, but to this day she still considers my son subordinate to her.
Robert Wilson
It’s all about status and exclusivity. And human beings are just as motivated by it as a pack animal. When Abraham Maslow created his Theory of Human Motivation in 1943, he identified five levels of motivation or five needs that humans strive to satisfy. Those needs are, in order: Survival, Safety, Social, Esteem, and Fulfilment.
Status is an esteem need and regardless of where we fall on the economic ladder, we all strive to achieve status before we can move on to the highest need. Whether we admit it or not, we all want to feel as if we are a little bit better than the people around us. We begin to establish that – at least in our own minds – with the accouterments of wealth such as branded clothing, jewelry, luxury automobiles, and exclusive neighborhoods. Even the poorest of people find symbols with which to establish their
status. The visibility of these status symbols can create the powerfully motivating emotion of envy.
Most happiness that is acquired by achieving status symbols is short lived. Overtime such trappings become meaningless to us, at which point, we seek genuine achievements to prove our worth. Studies have shown that after reaching a certain income level (usually around $250,000 a year) an individual’s happiness does not increase until they reach the status of super rich (approximately $10,000,000 a year).
But, status can continue to motivate us long after money ceases to do so. Bestowing a new title with added responsibilities yet without any added pay is a common method for rewarding employees.

tHe un-COmFORt ZOneBy Robert Wilson
Volunteers can be motivated in a similar fashion. I have been a Boy Scout leader for the past five years. The Boy Scouts of America rewards its leaders with patches embroidered with colorful square knots that are worn on the adult uniform. Different colored square knots represent the variety of services a volunteer has provided or achievements that he or she has earned. Some square knots represent achievements earned years earlier when the volunteer was a Boy Scout. When I attend formal full uniform functions, I find myself scanning fellow leaders’ square knots to note their status. There is one we all look for; it is the red, white and blue knot that indicates the wearer earned the highest status in scouting as a youth: the Eagle Scout award.
When the United States was founded, one of its distinguishing characteristics from the rest of the world was the lack of a feudal or caste system. That doesn’t mean
status doesn’t exist in America. Indeed it does, but here we must earn it. Best of all, people have a choice and can rise above the station they were born into.
Lacking status puts us in the Un-Comfort Zone and drives us to achieve. When you help someone up the social ladder, you can motivate them in a powerful and positive way.
“Bestowing a new title with added responsibilities yet without any
added pay is a common method for rewarding employees.”
