Purpose To compare the clinical performance of Sectional non – invasive laminate veneers (SNIVs) in patients with tooth diastemas in the frontal area.
Methods Ten patients with tooth diastema in the frontal area were included in this study. Each tooth diastema was treated with one feldspathic and one lithium disilicate sectional non-invasive laminate veneer. The veneers were evaluated by two investigators at baseline, immediately after cementation, at four and at twelve months of function according to the modified United States Public Health Service (USPHS) criteria. The parameters under evaluation included: anatomical form, marginal discoloration, marginal integrity, restoration color stability, secondary caries and surface texture.
Results Based on the clinical evaluation by the investigators, both groups had alterations in their anatomical form, developed marginal discoloration and loss of marginal integrity. On the other hand, the color of the restorations and the surface texture had no significant changes and no secondary caries were detected.
Conclusions Both groups of SNIVs had an acceptable clinical performance within 12 months of function in the oral cavity.
