A Retrospective Evaluation of 323 Porcelain Laminate Veneers

OBJECTIVES: The objetive of this study was to evaluate the clinical results of 323 porcelain lamínate veneers over a period of 3 to 11 years. METHODS: This study included 70 patients, aged between 18 and 74 years. Of the 323 total veneres, 124 were of a simple design and 199 were of a functional design. The condition of the soft tissues and higiene, in addition to the condition of the abutment teeth, the restorations and patient satisfaction were all clinically examined. In carrying out the statistical analysis, a descriptive approach was taken in analyzing the data. The Kaplan- Meier method was used for statistically analyzing the survival rates of the porcelain lamínate veneres. RESULTS: Analysis of the soft tissue revealed marginal recesión in 7.7% of the cases, and in 21.6% of the cases, bleeding was detecte on probing. Analysis the condition of the abutment teeth revealed secondary caries and hypersensivility in 3.1% of the cases, and changes in pulp vitality were observed in 2.8% of the cases. In studying the contition of the restorations, marginal integrity was observed to be excellent in 98% of the cases, slight marginal pigmentation was present in 39.3% of the cases, fractures were present in 4% of the cases and descementation in 9% of the cases. The degree of patient satisfaction was considered to be excellent in 97.1% of the cases. CONCLUSIONS: Porcelain lamínate veneres are predicable treatment option that offer excellent results.
