Computer-assisted surgery: double surgical guides for immediate loading of implants in maxillary postextractive sites.

Implant-supported prostheses are a predictable treatment of totally edentulous patients. Progresses in implantology allowed realizing prostheses that are supported by immediately loading implants. Implants can be inserted in the healed site as fresh extraction sites, without differences about long-term results. Using computer-assisted surgery, it is possible to insert implants in a predetermined position and to create a prostheses, which can be immediately fixed on the implants. Patients have major comfort and an immediate aesthetic and functional result. The use of computer-assisted surgery in fresh extraction sites is a procedure that has not been evaluated because of technical difficulties: teeth extraction eliminates references for surgical guides. The absence of guidelines to treat dentulous areas is often likely caused by lack of computer-assisted surgery: we attempted to use this procedure to replace residual teeth with an immediate implant prosthetic rehabilitation. The aim of this clinical report was to show the possibility to apply computer-assisted surgery in dentulous patient using a double surgical template: one before extraction and the other after extraction of selected teeth.
