14y Prospective Study on Posterior Zirconia-based 3-unit FDPs

Status Active, not recruiting

Clinical Trial Summary

The main objective of the present prospective study is to evaluate the effectiveness of posterior zirconia FDPs after 14 years of function.

Clinical Trial 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 ;
