Restauração semi-direta em resina composta em modelo de silicone: relato de caso clínico

Abstract

The advancement of restorative materials and the increasing demand from patients for more aesthetic procedures, composite resin has become the main choice for restorative treatments of posterior teeth. The choice of technique is crucial for ensuring that the treatment is not only easy to implement but also effective and contributes to the longevity of the rehabilitation process. The direct technique is indicated for cases with reduced proximal cavities, visible cervical margins, no cusp loss, and easy access. On the other hand, the indirect technique is recommended for deep cavities with compromised support structures, extensive coronal destruction involving more than two-thirds of the intercuspal distance, or the involvement of one or more cusps. The objective of this article is to describe, through a case report, the fabrication of a composite resin restoration on two lower premolars (44 and 45), using the semi direct technique over a semi-rigid model, demonstrating the step-by-step process from cavity preparation to cementation, with the aim of presenting the technique using addition silicone models as an alternative material for the fabrication of indirect composite resin restorations. It can be concluded that the restorative approach using the described technique proved to be a beneficial, viable, and easy-to-execute therapeutic option, successfully restoring both aesthetics and function to teeth with extensive coronal destruction.
