Start of the CAMLOG Guide drilling sequence with the pilot drill followed by drills of the appropriate lengths depending on the implant length (region 23). The treatment strategy for the maxilla in- cluded, as a first step, a conservative periodontal therapy of the anterior residual teeth for strate- gic preservation and fixation of the existing prosthesis until implant insertion. Afterwards, the residual teeth were removed and a bilateral sinus floor augmentation was performed in a two-stage procedure. Following 3-D planning, eight endosseous implants were inserted with the CAMLOG Guide System in a flapless procedure, and the prosthetic restora- tion was realised using a telescopic bridge. In the mandible, tooth #45 was removed and the other teeth were treated with conservative periodontal therapy. The mandibular posterior teethwerereplacedandrealigned.Teeth#43to33 received re-veneering of the removable denture.
