| Summary: | Objective To compare the clinical results of thin porcelain laminate veneer and conventional porcelain laminate veneer.Methods 20 patients were restored with 72 thin porcelain laminate veneers, and 45 patients were restored with 120 conventional porcelain laminate veneers. Clinical reevaluations were performed 3, 6, 12, 24 and 36 months after insertion of the veneers according to the modified USPHS-criteria. Survival-rate and success-rate were recorded.Results After an observation period up to 3 years, thin porcelain laminate veneers and conventional porcelain laminate veneers showed good clinical results in terms of secondary caries, marginal adaptation, marginal discoloration, color match and anatomic form. Both the survival-rate and success-rate were above 90%, and no significant differences were found between the 2 veneer groups with the correction for continuity Pearson 's χ2 test (P > 0.05).Conclusion Thin porcelain laminate veneer could obtain the same clinical results as conventional porcelain laminate veneer, however the indications should be selected properly and a higher level of operation technique is also required. A long period of clinical results remains to be observed. |
