Reparo De Restauração De Resina Composta: Revisão De Literatura E Apresentação De Caso Clínico

Abstract

The repair of composite resin restoration is a clinical procedure feasible and allows the removal of the engaged restoration without requiring complete replacement, and thus allowing the conservation of healthy tooth structure. The decision to keep part of the restoration and the clinical protocol of repair should be carefully evaluated and implemented to increase the predictability of the procedure. The bond between the old restoration surface and the composite resin to be added is based on the chemical and mechanical connection between these composites. The micromechanical preparation of the composite in combination with phosphoric acid and the use of fluid resin to improve the wetting of the surface increase the bond strength and efficiency of repair technique between composites. This study aimed to describe the technique of posterior tooth repair, performed in a composite resin restoration, describing the clinical protocol, the advantages and limitations of the technique.
