ABSTRACT
Objective: The objective of the study was to evaluate
and compare the clinical success rate of inlay and surface retained RB-FPDs
fabricated with fiber reinforced composite.
Material and Methods: This study was performed in Prosthodontic department de`Montmorency
college of dentistry. 172 RB-FPDs were completed with two preparation designs
having 86 cases in each design (inlay retained and surface retained).
Restorations were done on patients for single missing molar surrounded by
sound, healthy and well aligned abutments. RB-FPDs were fabricated in zirconium
silicate based indirect composite (ceramage) with incorporation of glass fibers
(Everstick C&B). Follow up was done after every six months till 18 months.
Complications (fracture, debonding, and dislodgment or abutment tooth caries)
developed during follow up were recorded and analyzed through SPSS version 17.
Results:
Overall success rate of 76.9% was observed in both designs of RB-FPDs. P value
of 0.190 showed insignificant statistical differences in success rate of two
designs however there was a trend towards better performance of inlay retained
RBFPDs. Fracture of the framework was most prevalent mode of failure followed
by debonding of the restoration.
Conclusion: The
fiber reinforced RB-FPD is a viable treatment option for replacement of single
missing posterior tooth.
