Falhas em laminados cerâmicos: revisão de literatura

Abstract

Ceramic laminates are indirect adhesive restorations indicated to correct aesthetic and functional teeth problems, and are a more conservative treatment of dental structure compared to full crowns. In spite of being a less invasive restorative procedure, it can present problems such as marginal infiltration, secondary caries, fractures, loss of retention, tooth hypersensitivity and colour change. This paper armed at presenting, as a goal, factors that influence the failures of aesthetic and functional of anterior teeth, using ceramic veneers, exposing parameters which guide the professional when planning and executing those restorations. A survey was done from data - LILACS, PUBMED, Brazilian Library of Dentistry - BBO an SCIELO, being used the descriptors dental facets, ceramic veneers and dental aesthetics. It is, however, restricted to essays of English and Portuguese language, printed between 2005 and 2020. It was checked that the ceramic veneers possess adequate longevity and that the main factors which arise flaws are related to the preparation of the dental element; the union of the tooth - restoration; the type of ceramics and the fabrication method used and the occlusal loads which happen upon those restorations. It was possible to conclude that the ceramic veneer is an efficient restoration treatment for the anterior teeth, but, they are submitted to flaws, if not observed important factors from the planning of the tooth preparation, selection of the ceramic material; cementation and protection of the restoration against deleterious occlusal loads.
