Cimentos resinosos autoadesivos

Abstract

The main objective of a luting agent are to fill the interface of the internal surface of the restoration and the prepared tooth, providing retention and resistance to the restoration and the remaining dental structure and the good marginal sealing to improve the longevity of the restorations. The self-adhesive cements are luting agents which present as proposal the adhesion to the dental substrate, with a simplified protocol of use. With the recent advent of these materials, is contemplated the necessity to know them better, since there are few studies regarding its clinical performance. Therefore, this study aimed to realize a brief review of literature about self-adhesive resinous cements on the chemical composition and bonding mechanism to the dental substrates, its indications and contraindications, its advantages and disadvantages, biocompatibility and adhesion the substrata. The self-adhesive resinous cements showed positive results in in vitro studies, being an alternative for the clinician as a luting material. However, it's worth pointing out that more scientific considerations and studies in vivo regarding these cements are necessary to direct their appropriate use and to clarify doubts still frequent.
