AbstractBackground:The present study was conducted to assess causes of failures of FPD.
Materials & Methods: 142 patients of both genders who had FPD failures due to various reasons were included. The cause of failure was recorded.
Results: Esthetic causes were over contoured margin in 12, under contoured margin in 6 and unacceptable color match in 8 cases. Other causes of failures was loss of retention in 30, periapical pathology in 12, bridge fracture in 10, caries in 8, coronal tooth fracture in 7, occlusion problem in 5, porcelain fracture in 13, mobility of abutment in 5, perforation in 4, food lodgement in 8, occlusal wear in 10 and sinus formation in 2 cases. The difference was significant (P< 0.05).
Conclusion: Common cause of failures was under contoured, over contoured margin, loss of retention and periapical pathology.
