[Analysis of enamel thickness of anterior teeth and its relation to preparation for porcelain veneers].
The development of porcelain, acrylic and mixed crowns is not under discussion. In the same way, it should not be discussed now the evolution of silicate cements, the acrylics, the glass ionomer and the composite resins in their different techniques. We only want to analyze concisely the actual condition of the investigation and of the clinic, as regards the reconstruction with lamellas of the front part of the mouth. Lit can be deduce from the researches that the measurement of the vestibular thickness of y the enamel upon the incisives, laterals and canines specifies that: 1. As regards form, the most suitable elements for the laying of the porcelain laminate are the square, then the ovoid and finally the triangular ones. 2. The central incisives are the best; secondly the canines and then the laterals (this is directly related to the convexity of the fronts and to the amount of residual enamel). 3. It is advisable to finish the peripheric edge of the cavity 1 mm, above the anatomic neck to assure an adequate thickness of enamel in order to obtain a good adherence of the porcelain laminate veneers. 4. It is convenient to use appropriate techniques during the adamantine preparation in order to control its depth (for example diamond-like stones with ends).
