A Systematic Review and Meta-Analysis of the Survival of Non-Feldspathic Porcelain Veneers Over 5 and 10 Years
ABSTRACT Purpose: This systematic review aimed to report and explore the survival of dental veneers constructed from non-feldspathic porcelain over 5 and 10 years. Materials and Methods: A total of 4,294 articles were identified through a systematic search involving all databases in the Cochrane Library, MEDLINE (OVID), EMBASE, Web of Knowledge, specific journals (hand-search), conference proceedings, clinical trials registers, and collegiate contacts. Articles, abstracts, and gray literature were sought by two independent researchers. There were no language limitations. One hundred sixteen studies were identified for full-text assessment, with 10 included in the analysis (5 qualitative, 5 quantitative). Study characteristics and survival (Kaplan-Meier estimated cumulative survival and 95% confidence interval [CI]) were extracted or recalculated. A failed veneer was one which required an intervention that disrupted the original marginal integrity, had been partially or completely lost, or had lost retention more than twice. A meta-analysis and sensitivity analysis of Empress veneers was completed, with an assessment of statistical heterogeneity and publication bias. Clinical heterogeneity was explored for results of all veneering materials from included studies. Results: Within the 10 studies, veneers were fabricated with IPS Empress, IPS Empress 2, Cerinate, and Cerec computer-aided design/computer-assisted manufacture (CAD/CAM) materials VITA Mark I, VITA Mark II, Ivoclar ProCad. The meta-analysis showed the pooled estimate for Empress veneers to be 92.4% (95% CI: 89.8% to 95.0%) for 5-year survival and 66% to 94% (95% CI: 55% to 99%) for 10 years. Data regarding other non-feldspathic porcelain materials were lacking, with only a single study each reporting outcomes for Empress 2, Cerinate, and various Cerec porcelains over 5 years. The sensitivity analysis showed data from one study had an influencing and stabilizing effect on the 5-year pooled estimate. Conclusion: The long-term outcome (> 5 years) of non-feldspathic porcelain veneers is sparsely reported in the literature. This systematic review indicates that the 5-year cumulative estimated survival for etchable non-feldspathic porcelain veneers is over 90%. Outcomes may prove clinically acceptable with time, but evidence remains lacking and the use of these materials for veneers remains experimental.

ABSTRACT: This study evaluated the long-term clinical performance of porcelain laminate veneers luted with hybrid composite in combination with total-etch and self-etch adhesive systems. The study was performed on 30 patients ranging in age between 28 and 54 years. Ten veneers were performed per patient in the maxillary arch. In Group 1, 150 teeth were treated with porcelain veneers, using a total-etch adhesive system (Scotchbond Multi-Purpose Plus, 3M ESPE). In Group 2, 150 teeth were bonded with a self-etch adhesive system (AdheSE, Ivoclar-Vivadent). All the veneers were luted with a light-cured hybrid composite (Z100, 3M ESPE). The patients were recalled after 1, 2 and 5 years. Modified United States Public Health Service (USPHS) criteria were utilized to evaluate the porcelain laminate veneers in terms of marginal adaptation, cavo-surface marginal discoloration, secondary caries, postoperative sensitivity, satisfaction with restoration shade and gingival tissue response. Data were analyzed using the Chi-Square test (p < 0.05). There was no statistically significant difference between the total-etch and self-etch groups in terms of USPHS criteria (p > 0.05). Porcelain veneers exhibited successful clinical performance with both total-etch and two-step self-etch adhesives at the end of five-years.Operative Dentistry 09/2009; 34(5):516-23.

ABSTRACT: The objective of this study was to evaluate the clinical results of 323 porcelain laminate veneers over a period of 3 to 11 years. This study included 70 patients, aged between 18 and 74 years. Of the 323 total veneers, 124 were of a simple design and 199 were of a functional design. The condition of the soft tissues and hygiene, 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 laminate veneers. Analysis of the soft tissue revealed marginal recession in 7.7% of the cases, and in 21.6% of the cases, bleeding was detected on probing. Analysis of the condition of the abutment teeth revealed secondary caries and hypersensitivity in 3.1% of the cases, and changes in pulp vitality were observed in 2.8% of the cases. In studying the condition 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 decementation in 9% of the cases. The degree of patient satisfaction was considered to be excellent in 97.1% of the cases. Porcelain laminate veneers are a predicable treatment option that offer excellent results.Medicina oral, patologia oral y cirugia bucal 05/2010; 15(3):e531-7.
