Complications and their severity in patients of conventional metal ceramic fixed dental prosthesis: a clinical study

ABSTRACT

The aim of this study was to present the frequency of biological and technical complications and its severity related with metal ceramic fixed partial dentures [FPDs]. Total 245 abutments of 140 patients presented with complications in their FPDs were examined. The mean age of the patients was 42 years [range 23-83]. 66.1% and 33.8%complication were found in the FPDs provided by qualified and unqualified persons respectively with an average 5.4 years length of services. Among the biological complications caries were present in 21.2% [52] of the abutment teeth; 13.06% [32] had periapical problems, 12.65% [31] periodontal problems and 2.85% [7] had abutment fracture. Sixty eight out of 245 abutments with a decementation problem indicated a the major technical complication, whereas 25 with esthetic problem, 15 had occlusal problems. The primary technical complication decementation was associated with wrong preparation. Varying severity grades of complications, grade I 27.3%, grade II 35.1% and grade III 37.5% were observed. In conclusion majority of the FPDs having complications were provided by unqualified and were of grade II and III. The common complications were de-cementation, dental caries, periodontal disease and periapical problems
