TI  - Clinical evaluation of zirconia-based restorations on implants: a retrospective 
      cohort study from the AIOP clinical research group.

AB  - PURPOSE: The aim of this retrospective cohort study was to evaluate the clinical 
      performance of zirconia-based implant-supported single crowns and fixed dental 
      prostheses (FDPs) made by 15 members of the Italian Academy of Prosthetic 
      Dentistry (AIOP) over a time period of up to 5 years. MATERIALS AND METHODS: One 
      hundred thirty-one patients were treated with a total of 210 zirconia-based 
      single crowns and FDPs on implants in anterior and posterior regions. A cohort 
      group with parafunctional habits was compared with patients without 
      parafunctional habits according to the esthetic, functional, and biologic United 
      States Public Health Service criteria modified by the FDI World Dental 
      Federation. RESULTS: The estimated cumulative survival (ECS) and standard error 
      (SE) of all restorations on implants was 91.95% +/- 1.39%, and the estimated 
      cumulative success (ECSs) and SE was 88.37% +/- 1.72%. The ECS of single crowns and 
      FDPs was 91.25% +/- 3.69% and 95.23% +/- 2.28%, respectively, and the estimated 
      cumulative success rates were 88.84% +/- 2.05% and 87.96% +/- 3.16%, respectively. 
      Mechanical failures, including four zirconia core fractures, three hairline 
      cracks, four chippings, and five delaminations of the ceramic veneering material, 
      were recorded during a 1- to 5-year observation period. The odds ratio of 3.39 
      (95% confidence interval: 1.18 to 9.73) showed a moderate association between 
      parafunction and failure. CONCLUSIONS: Zirconiabased implant-supported 
      restorations showed encouraging clinical results over a period of up to 5 years, 
      but more clinical data are needed before these restorations can be considered a 
      viable treatment alternative. Mechanical failures were primarily observed in 
      patients with parafunctions.
