Palatogram Utilization

for Phonetic Adaptation

in The Maxillary Full Denture

Background

There were many cases in phonetic disruption or unclear pronounciation

after first insertion of maxillary full denture

Less evaluation in phonetic function ->

Most evaluations are in aesthetic,

mastication system, and patient's comfortable

Background

Factors affecting

adaptation of

maxillary full denture

Patient’s experience

Age Gender

Rugae’s duplicate

Background

Importance of adding rugae’s duplicate into the maxillary full denture to increase phonetic adaptation

Literature Review

Anatomy and Physiology of Palatal Rugae

Literature Review

Classification of Palatal Rugae

Literature Review

Role of Palatal Rugae in Prosthodontics

Increase the sound quality of full denture

Increase Phonetic

Adaptation

Literature Review

Steps to Duplicating Palatal Rugae

Record the rugae with putty elastomeric

Cut the wax in 1 mm as a "stop" in

three sides. Apply the separating medium

on the model and put the acrylic

After the acrylic has setting,

take it from model with air spray,

and then trim it.

Steps to Duplicating Palatal Rugae

Move the palatal rugae area from the base

and apply the palatal rugae's duplicate.

Add wax on base , invest, and flasking

Literature Review

Palate's speaker reviewed by black

powder -> Speaker usually pronounce

the single consonant

In Articulation: the tongue will removes

the powder on several parts-> Use mirror to take the

photo

The images: The place of articulation

on erased area where the powder

is spreaded -> palatogram

• Patients who lost their teeth -> Different in oral cavity and speaking habit

• Dentist must design the shape and expansion of the denture correctly -> restore the function of the teeth and oral structures

• One of them: restore the phonetic function simultaneously used as a clinical requirement in making an appropriate full denture

• Dentists need to know about the science of studies about phonetic so it can be used as a guide in making prostheses.

• One of the method is with palatal rugae's duplication

Conclusion

• Palatal rugae’s shape is stable because it does not change over time, and unchanged from the first form to the oral mucosa until it degenerates at the time of death.

• Its uniqueness in each individual serve as identification of individuals so that duplication of rugae must record on each individual.

• Duplication of rugae will form a certain patterns as close as normal palatum from the patient so it can help the patient in phonetic adaptation

• Using of palatal rugae's duplication is expected can reduce the disruption of phonetic adaptation in full denture patient. Palatogram can be used as a technique for assess the phonetic adaptation.
