Influência Do Condicionamento Ácido No Reparo De Cerâmicas Odontológicas Utilizando Resina Composta

Abstract

The use of ceramic restorations is constantly indicated and used in dental clinics because of their structural and aesthetic qualities, however despite being a material with excellent mechanical properties it may present fractures. The complete replacement of a prosthetic restoration has an elevated cost and needs a longer clinical time. So the repair of ceramics using composite resin has been a good alternative in cases of fracture. The objective of this study is to evaluate through a literature review the influence of acid etching in the repair of ceramic with composite resin. The data collection was performed through the selection of articles published in the databases SciELO, LILACS and Bireme using the following descriptors: surface treatment, composite resin and dental ceramics. According to the findings gathered, the repair of fractured ceramic surface can be performed intra-orally through the mechanical and chemical treatment of the fractured surface. For acid sensitive ceramics it is reported in literature the effectiveness of hydrofluoric acid treatment in promoting superficial alterations, however, the longevity of such adhesion between ceramic and composite resin after etching is still questionable.

Current Considerations for Dental Ceramics and Their Respective Union Systems

“…They are susceptible to hydrofluoric acid conditioning and are classified as acid-sensitive, where associated with the application of the silane agent inside the restoration, it provides a high index of adhesion to the dental structure, also obtaining flexural strength. 11,14 Panah, Rezai, Ahmadian 15 also carried out a study showing that glass-matrix ceramics can be adhesive cemented, since they have silica in their composition, in this way, the chemical union with the resin cement is related to the previous application of silane, because some studies show that it positively influences the strength and union durability.…”
