ABSTRACT
The success of extra-oral implants raises a certain number of technical and medical problems. Among these, the anatomy of the implant zone and bone quality are determining factors for osteointegration of the implants. We describe the principal zones of implantation detailing the risks involved in each area.

Edentulism is often reported after treatment for malignancy of oral cavity. The resulting deformities from loss of teeth and bone create a "social invalid" with difficulties in articulation and mastication. Prosthetic rehabilitation was difficult because of two problems: the risk of osteoradionecrosis development and local anatomic modifications. The introduction of osseointegrated implants improved results of oromandibular reconstruction. A preliminary report of nineteen Branemark implants of seven patients is reported here. Implants have been in place and functioning for a period of one to four years. No major complication occurred and osseointegration permitted good oral rehabilitation. Placement of osseointegrated implants in osteomyocutaneous flaps and in irradiated bone is discussed.

This investigation was conducted to evaluate 20 cases of implant-retained prosthetic rehabilitation (mean follow-up of 35 months). Ear, nose, orbit and complex defects of the face have been restored. Our main indication was reconstruction in cancer patients after tumor surgery (n = 14). Rehabilitation was also performed in traumatic disorders (n = 3) and congenital aural malformations (n = 3). Fifty seven titanium fixtures have been implanted with an integration success rate of 98%. We also report 6 cases of maxillary or mandibulary functional rehabilitation. The use of osteointegrated implants to provide support for maxillo-facial prosthesis is a new and valuable technique when reconstructive plastic surgery is not envisageable.
