The objective of this study was to evaluate the mechanical, biological and aesthetic performance of
ceramic veneers after 5 to 7 years of service. The ceramic veneer restorations were clinically examined using a
modified criteria of the United States Public Health Service (USPHS) and World Dental Federation (FDI). Clinical
evaluation was performed by two clinicians during maintenance appointments between September 2016 and August 2017. Intra-examiner and inter-examiner reliability was evaluated by calculating the intraclass correlation coefficient and by inter-examiner calibration. The results were analysed by the Kaplan-Meier survival estimation method and log-rank test at a 95 % confidence level. One hundred and sixty-three veneers [a mean clinical service of 68.1±0.66 months] were examined. Overall survival rate of the veneer restorations was 97.5 % with 2.5 % (four veneers)
presenting clinically unacceptable problems, such as fracture and debonding. Caries were not detected in any teeth.
Radiographic examination found the development of a periapical lesion in one patient after veneer placement.
Veneer placement in premolars showed a higher failure rate than other dental regions. Most patients were
comfortable with their restorations and satisfied with the aesthetic results. Ceramic veneers demonstrated a high
survival rate with most failure cases resulting from fracture and debonding.
