Clinical evaluation on porcelain laminate veneers bonded with light-cured composite: results up to 7 years

Abstract

The purpose of this study was to evaluate the clinical performance of laminate porcelain veneers bonded with a light-cured composite. Thirty patients were restored with 119 porcelain laminate veneers. The veneers were studied for an observation time of 7 years. Marginal adaptation, marginal discoloration, secondary caries, color match, and anatomic form were clinically examined following modified United States Public Health Service (USPHS) criteria. Each restoration was also examined for cracks, fractures, and debonding. Pulp vitality was verified. In addition, plaque and gingival indexes and increase in gingival recession were recorded. Survival rate evaluating absolute failures and success rate describing relative failures were statistically determined, using both restoration and patient-related analyses. On the basis of the criteria used, most of the veneers rated Alfa. After 7 years, the results of the clinical investigation regarding marginal adaptation and marginal discoloration revealed only 2.5% and 4.2% Bravo ratings, respectively, among the 119 initially placed veneers. Using the restoration as the statistical unit, the survival rate was 97.5%, with a high estimated success probability of 0.843 after 7 years. Using the patient as the statistical unit, the survival rate was 90.0% and the estimated success probability after 7 years was 0.824. Gingival response to the veneers was all in the satisfactory range. Porcelain laminate veneers offer a predictable and successful treatment modality giving a maximum preservation of sound tooth. The preparation, cementation, and finishing procedures adopted are considered key factors for the long-term success and aesthetical result of the veneer restorations.

In vitro evaluation of accuracy and precision of automated robotic tooth preparation system for porcelain laminate veneers

“…However, the result of the robotic tooth preparation system showed a significantly higher level of both accuracy and precision at the finish line. The preparation of the finish line is most challenging and critical for the long-term clinical success of PLVs because of the limited amount of enamel in the cervical area 8,11,12 and the risk of traumatizing gingival tissue. These results suggest that the application of robotic technology for tooth preparation for PLVs is beneficial.…”

“…[1][2][3][4][5][6] Multiple clinical studies have demonstrated that when PLVs are bonded to enamel (at least 50% bonding surface is enamel) and when the finish-line is placed supragingivally on enamel, these restorations are extremely successful. [7][8][9][10] The enamel thickness of anterior teeth varies according to area and tooth type. 11,12 Clinically, the average enamel thickness has been used as one of the references for the tooth preparation of PLVs.…”
