PURPOSE:: The aim of this study is to demonstrate the accuracy and clinical precision of a guided surgery protocol by using traditional Brånemark System abutments in conjunction with a prefabricated all-acrylic provisional prosthesis that is immediately installed after implant placement. MATERIALS:: All presurgical methods in this treatment follow the standard NobelGuide protocol with the exception of the laboratory phase. Once the master cast is retroengineered from the surgical template, traditional Brånemark System abutments were secured onto the implant replicas (master cast) and an all-acrylic provisional prosthesis was constructed at the abutment level. The typical abutments used with this protocol, adjustable Guided Abutments, were not used. RESULTS:: Twenty-three patients were treated in this pilot study. Via the surgical template, all implants were placed to the desired depth as planned in the virtual implant planning program. After the traditional Brånemark Abutments were installed, the provisional prosthesis was delivered and occlusion verified. The prosthesis fit was checked at abutment level clinically and radiographically. CONCLUSION:: This report shows the extreme accuracy of this guided surgery protocol. If each step of this protocol is followed precisely, it is possible to deliver a prefabricated prosthesis built to traditional Brånemark System Abutments, which is extremely favorable for long-term patient and prosthesis management.
