Substituição de restauração de amálgama por restauração semidireta do tipo onlay em molar inferior: relato de caso clínico

Restoring posterior teeth with structural loss can pose a challenge to the recovery of function and aesthetics. In this context, a semidirect onlay restoration represents a conservative alternative, as it allows the preservation of tooth structure and the restoration of tooth anatomy and function. This study aims to report a clinical case involving the replacement of an amalgam restoration in tooth 46 with a semidirect onlay restoration. Treatment involved amalgam removal, tooth preparation, fabrication of the restoration, and subsequent cementation. The technique enabled the preservation of sound tooth structure while providing adequate restoration of masticatory function and tooth anatomy. Thus, the semidirect onlay restoration proved to be a conservative and effective option for the rehabilitation of posterior teeth, combining tooth preservation, function, and aesthetics.
