Cerâmicas ácido resistentes: a busca por cimentação resinosa adesiva

Abstract: INTRODUÇÃOAs cerâmicas são, sem dúvida, um dos materiais odontológicos de grande expressão na odontologia moderna. São biocompatíveis, apresentam alta resistência à compressão, estabilidade química, e grande potencial estético, pois permitem reconstruir artifi cialmente as particularidades das estruturas dentais, características importantes na reabilitação estética e funcional. São compostas de elementos metálicos (Al, Ca, Li, Mg, K.Na, Zr, Ti) e não metálicos (O, Si, B, F ). A combinação destes pelos fabrican… Show more

“…Glass fiber posts were indicated because they have a modulus of elasticity close to that of the dental remainder, as they satisfactorily distribute the forces exerted on the tooth structure to reduce the risk of fracture, in addition to being esthetic [17][18][19]. The dental preparation must contemplate fundamental mechanical principles (retention, resistance to displacement or stability, structural rigidity and marginal integrity), in spite of the large increase in retention and strength of the restoration promoted by the bond strength to enamel [20][21][22] . The reduction of tooth tissue for total crowns must demand minimal thickness to support the ceramic material, with adequate expulsion and rounded angles, and with limits in tooth enamel.…”

“…By the surface treatment and silanization process, adhesive cementation for this restoration presupposed the obtainment of strong and reliable bond strength to the remaining tooth structure, which allowed better distribution of loads during mastication, diminishing the risk of cementation failure or fracture of the restoration 20 . Adhesive resin cementation also improves the prognosis in case of short or expulsive posts, and partial restorations such as the laminated facet type 22 . The patient under treatment presented clinical signs of sleep bruxism, also reported by family members.…”

“…The conditioning can be done by blasting, laser application and acid etching 10 . The acid reacts with the glass-matrix of the ceramic which is selectively removed, exposing the crystalline phase, leaving a rough surface and increasing the micromechanical retention for adhesive cementation with composite resin cements 8 .…”

“…Hydrofluoridric acid modifies the material surface, causing roughness and microporosities which increase the adhesion surface area, favoring silane retention, increasing the surface wettability and surface energy [10][11][12][13][14] .…”
