Abstract In modern dentistry, fibre-reinforced fixed dental prostheses are

considered a useful alternative to classical metal-ceramicrestorations. This method allows a conservative approach forreplacing missing teeth that overcomes some of the drawbacks ofconventional prostheses. Our patient required extraction of tooth#46 because of an apical lesion of the mesial root, and underwentextraction by hemisection. After healing, using the superiorproperties of the combined fibre/composite, an adhesive bridgerestoration was applied with support from the distal root of tooth#46 and teeth #45 and #47.

IntroductionFor many years, the only prosthetic application

used to deal with cases with a single missing toothwas a fixed partial prosthesis. However, thepreparation of the two teeth required for correctionof a single tooth deficiency causes unnecessarytissue loss. Subsequently, implant-supported fixedprostheses have been developed as an effectivesolution for this situation. Inevitably, implantscannot be used in some patients because surgicalintervention is contraindicated due to systemicdisease or the high cost of the operation. Adhesivebridges are a good alternative, as they are lessexpensive than implants, they do not requiresurgical intervention and the loss of material fromthe supporting tooth is small compared toconventional bridges. With the development of fibre-strengthened composites, alternative restorationshave become very popular (1-4).

Fibre-reinforced composites have goodmechanical properties and their endurance/weightratios are high compared to metal alloys. Fibre-reinforced composites have several advantages:they are translucent, unlike metals; non-corrosive,easy to repair, have good adhesive properties and it

is easy to prepare the mouth to receive them. Indentistry, glass, polyethylene and carbon fibres aremainly used as the strengthening materials forcomposites. Saturated fibres are used as thesubstructure material for a fixed partial prosthesis,whereas ceramic-reinforced restorative compositesare used as the superstructure material (1-7)

Case Report

A 31-year-old male patient visited our facultycomplaining of problems with tooth #46, and anapical lesion of the mesial root was detected. Basedon the results of radiography and intraoralinspections, the distal root of the tooth was deemedusable (Fig. 1A). After endodontic therapy, the toothwas hemisectioned and the mesial root wasseparated (Fig. 1B and Fig. 1C). Following thehealing period, a mandibular impression wasobtained and tooth wax was used to plan the body-gum relationship for model preparation (Fig. 1D andFig. 1E).
