CAUSES OF FAILURES IN CERAMIC VENEERS RESTORATIONS: A LITERATURE REVIEW.

Aim: In an attempt to clarify the techniques used in ceramic veneers due to the scarce literature on the subject, it is aimed, through a review of literature, to analyze the main causes of failures of this type of procedure. Methodology: An electronic search of publications was carried out in the following databases: Google Scholar, PubMed, SciELO; using the following descriptors: Esthetic Dental, Dental Veneers, Dental Restoration Failure and Ceramics. The following were adopted as inclusion criteria: articles published in English and Portuguese, articles published between the years 2000 to 2018 and articles whose subject matter is restricted to the subject of ceramic veneers. Results: Through the review, all the works presented that the 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 total crowns that always require greater reduction of dental structure. Conclusion: There are certain factors that are of great importance for the success and longevity of the procedure 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.
