Purpose:This study evaluated the long-term survival of anterior porcelain laminate
veneers placed with and without incisal porcelain coverage. Materials and Methods:
Two prosthodontists in a private dental practice placed 110 labial feldspathic porcelain
veneers in 50 patients; 46 veneers were provided with incisal porcelain coverage, and
64 were not. The veneers were evaluated retrospectively from case records for up to 7
years (mean 4 years). Results:At 5, 6, and 7 years, the cumulative survival estimates
were 95.8% for veneers with incisal porcelain coverage and 85.5% for those without
incisal coverage. The difference was not statistically significant. Six of the nine failures
occurred from porcelain fracture in the veneers without incisal coverage. Conclusion:
Although there was a trend for better long-term survival of the veneers with incisal
porcelain coverage, this finding was not statistically significant. Int J Prosthodont
