Abstract

Veneers: Failures and Complications

Ceramic veneers restorations consist of a very interesting prosthetic alternative for teeth shape modification, position in the matter of slight corrections, correction of structural defects, color modification, occlusal rehabilitation, among other indications. It is often possible to return the aesthetic balance of the smile with little or no dental wear, which characterizes the procedure as minimally invasive and relatively conservative, when compared to full crowns that always require greater reduction of dental structure. However, all this excellence can only be achieved if there is knowledge of the basic principles of dental aesthetics, as well as the excellent mastery of the technique beyond indication, choice of material, correct technique and follow up. It can then present disadvantages such as the need for preparations with greater wear of dental structure, marginal maladaptation, dentin sensitivity, and even fractures. With the evolution of strong materials, the reinforced ceramics were created, with the addition of crystals such as alumina, leucite, lithium disilicate and zirconia, that increase the resistance of the material, and these innovations made possible the use of minimally invasive technique. There are certain factors that are of great importance for the success and longevity of the procedure such as the correct indication of the treatment and adequate choice of the restorative material, followed by dental preparation; the use of the precise technique, with the field isolated and free
of any contamination. All previously mentioned factors if not considered, the rate of success will decrease and more complications may arise.
