About
The main objective of the present prospective study is to evaluate the effectiveness of posterior zirconia FDPs after 14 years of function.
Full description
thirty-seven patients needing to replace either premolars or molars were involved and 48 3-unit zirconia-based FDPs were fabricated. Patients included in the present clinical study met specific inclusion criteria and clinical procedures were standardized.
Frameworks with a 9 mm2 cross section of the connectors and 0.6 mm minimum thickness of the retainers were made by means of Computer Aided Design/Computer Assisted Manufacturing. A resin cement was used to lute the restorations. The patients were recalled after 6 and 12 months and then yearly up to a total follow-up of 14 years. The United States Public Health Service criteria were used in order to examine technical and esthetic outcomes. Success and survival rates
