Abstract
Veneer restorations are one of the most conservative and aesthetic techniques
applied as treatment of unaesthetic anterior teeth as they avoid aggressive dental preparation; thus, maintaining tooth structure. The continued development of materials offers clinicians many options for creating highly aesthetic and functional laminate veneers. Correction of minor malformations of anterior teeth with minimal removal of the remaining tooth structure, correction of crown length and width, diastema closure and masking, as well as some intrinsic discoloration of anterior teeth are examples of solutions that can be gained with using porcelain veneers. Initially, laminates were placed on the
unprepared tooth surface. Although there is as yet no consensus as to whether or not teeth should be prepared for laminate veneers, currently, more conservative preparations have been advocated. Because of their aesthetic appeal, biocompatibility, and adherence to the physiology of minimalinvasive
dentistry, porcelain laminate veneers have now become a restoration of choice.
Today, limited controversial information is available regarding the influence of preparation design on the longevity of laminate restorations. The purpose of this presentation is to attempt to review the different incisal preparation designs of porcelain laminate veneers for anterior teeth. A further objective is to understand which is the most successful design in terms of preparation.
