Prospective Evaluation of Zirconia Posterior Fixed Partial Dentures: 7-Year Clinical Results

Abstract

After a mean observational period of 7 years, the survival and success rates of zirconia-based posterior FPDs were inferior to those published for metal-ceramic FPDs. The majority of failures were caused by technical complications (material fractures). The main reasons for clinical intervention to maintain function were fractures of the veneering ceramic and decementations.
