• Abstract: In the case of posterior teeth with extensive destruction of their crowns, the indirect technique is the one of choice, where it is possible to present a restoration with more detailed anatomy, precision at the point of contact, marginal adaptation and compensating for polymerization contraction at the time of cementation. The present study aims to report and illustrate the technique for creating an indirect restoration in an acrylic posterior tooth made with composite resin, made using a semi-rigid model carried out in the laboratory. Only one acrylic tooth underwent onlay preparation. A double disposable tray and quick-setting alginate were used to mold the preparation, and light addition silicone was used to create the working model. A die was made and then the composite resin restoration. The present work concluded that it was possible to report and clarify the technique for creating an indirect restoration that meets the clinical needs of restoring shape, function and anatomy of extensively decayed and destroyed posterior teeth.
