In the last decades the development of the porcelain materials, the reliable bonding strength to enamel and dentin, and the bonding of resin cement to the porcelain through the silane, Porcelain laminates become trusted type of treatment in the daily practice. It is an aesthetic treatment that concerns mainly the labial face of the anterior teeth, its thickness is about 0.3 mm in the cervical area to 0.4 -7 at the incisal third, in certain cases it can be done without any prep or just little touch of the enamel (lumineer), but in most prep is indicated to improve the adaptation in the cervical area also to remove the aprismatic enamel layer which which has low bonding strength with the resin cement, however prep should be in the enamel limits, 3 different type of prep are practiced, however, they are the same on the labial surface but the but the difference concerns the incisal edge. In this lecture, indications and contraindications are exposed. All the materials in use and their indications as well as the clinical procedures are detailed.

Porcelain laminate veneers are among the most esthetic means of creating a more pleasing and beautiful smile. Porcelain veneers within reason allow for the alteration of tooth position, shape, size and color. They require a minimal amount of tooth preparation, approximately 0.5 mm to 0.7mm of surface enamel reduction. This study describes the use of ceramic veneers without tooth wear, reinforcing the concept that minimally invasive porcelain laminate veneers could become versatile and conservative allies in the fi eld of esthetic dentistry.
