Insucesso na reabilitação direta com resina composta: principais causas

Abstract

Composite resins are one of the most researched dental materials at the moment. Allow aesthetic restorations from less invasive preparations combined with the evolution of adhesive systems and physical and mechanical properties of composite resins. They feature clinical longevity, but dependent on some factors. Thus, the present study aims to point out which are the main factors that contribute to the failure in direct restorations with composite resin. For that, a search was performed in the online databases PubMed, Lilacs and Scielo, using as descriptors: "failure AND composite resin AND direct restoration". 129 articles were found, published in the English language, between 2015 and 2020, of which 26 were included. The analysis of the results showed that we observed factors related to the patient, such as risk of caries, high blood pressure occlusal and socioeconomic condition, aspects associated with the operator, such as correct diagnosis, planning and operative technique, characteristics of the cavity, such as the number of walls involved in the cavity preparation to location of the dental element in the dental arch influences clinical longevity. Among the main reasons for failure in direct restoration in composite resin in the posterior teeth observed were secondary caries and fracture, while in the anterior teeth there are highlights related to aesthetic appearance. It can be concluded that, that direct composite resin restorations are presented as restorative options with good clinical performance, in the However, it is of fundamental importance to control the factors involved in the restoration failures.
