Abstract
Objectives Primary aim of this study was to evaluate survival rate of lithium disilicate veneers
in upper and lower anterior teeth. Secondary aims were to evaluate changing in proportions
of teeth before and after restorations and to assess mean thickness of the veneers.
Materials and Methods Seventy-nine upper and lower lithium disilicate veneers were made in 13 patients
with worn teeth. Mean follow-up was 3 years. To perform anterior definitive rehabilitations,
malocclusions and loss of vertical dimension were treated by full mouth rehabilitations
to obtain proper occlusal conditions. Veneers were made of lithium disilicate core
and fluorapatite-based ceramic stratification. Survival rate was calculated by Kaplan–Meier
analysis. Changing in teeth proportion before and after restorations was analyzed
by a paired t-test. Descriptive statistics of thickness values were also performed.
Results One case of detachment was observed with a 98.7% survival rate. Teeth’s proportions
were preserved although the first upper right incisor and canine changed in dimension.
Conclusions Lithium disilicate veneers in esthetical rehabilitations of worn teeth proved to
be an effective way of treatment in a medium follow-up of 3 years. Proportions seemed
to be maintained with a minimum dental removal.
