Abstract

Abstrac t Objectives. This observational study aims to clinically verify the rate of success of Fixed Partial Dentures (FPDs) made of resin and glass fiber composite (Fiber- Reinforced Composite, FRC). Materials and methods . Our study sample involved 50 subjects (30 males and 20 females) aged between 14 and 45 who have been rehabilitated with FRC Maryland bridges (for a total of 67 FPD-FRC). The observational study was performed for five years following the general rules coded by the modified US Public Health Service (USPHS) system. Resu lts. After five years of follow-up, seven out of 67 prosthesis (five belonging to the adult group and two belonging to the adolescent group) were found unsuitable. Four of these FPD-FRCs were considered unsuitable because of break of the framework, the remaining three FPDFRCs were regarded unsuitable because of leakage of the marginal seal. Conclus ions. This clinical investigation showed that the FPDs made with FRC technique can be considered a viable alternative to the traditional removable and fixed prosthesis.
