Bonding of resin composites to etchable ceramic surfaces - an insight review of the chemical aspects on surface conditioning

Abstract

The longevity of silane promoted adhesion of the surface conditioned etchable ceramic materials is a continuous and costly concern in dentistry. Moreover, it poses a functional and aesthetic dilemma both for the dentist and the patient. Several methods for surface conditioning exist, however some of them are not any more widely in clinical use. Tribochemical silica-coating combined with silane application, compared in vitro and in vivo to some other silanization protocols, is according to the literature a clinically proved, relevant adhesion promotion method to enhance bonding of resin composites to etchable ceramics. The repair of fractured ceramic with tribochemical silica-coating and followed by a silane application is, according to the literature a relevant adhesion promotion method in prosthetic dentistry. Silica-coating is followed by a silane coupling agent application. The bonding is adequate for clinical use according to the literature study.
