RESUMO
The gingival tissue reactions around 19 titanium implants (Brånemark System) and 6 ceramic implants (Frialit) were studied by using established variables for monitoring periodontal status. Natural teeth in the same or the opposite jaw served as controls. Both clinical and laboratory examinations showed healthy gingival status. No differences in soft-tissue reactions between the two types of implant or between the implants and the natural teeth were registered.

Attention is called to the fact that in cases of large ameloblastomas systematic, careful treatment is essential. This implies proper reconstruction of the jaw and restoration of the occlusion after adequate extirpation of the tumor. A case involving a large mandibular ameloblastoma is reported. It was successfully treated, step by step, by tumor extirpation, jaw reconstruction with rib transplants and installation of titanium implants (Biotes) in the rib transplants, anterior vestibuloplasty with skin graft, and, finally, an overdenture. Carefully planned coordination of well-documented surgical and prosthetic procedures has achieved a functionally and esthetically successful result.

This paper reports the results of clinical series of osseointegrated implants (BiotesTM) at the Karolinska Institute, Stockholm. From 1980 to 1985, 350 implants were installed in 68 upper jaws and 440 implants in 83 lower jaws. After observation periods of 1 to 6 years, 307 (88%) maxillary implants and 434 (99%) mandibular implants were fully functional. Of 128 bridges and 23 overdentures 124 (97%) and 21 (91%) respectively were in function at the end of the observation time. The most frequent tissue complications were fistulae (8 cases) and mucosal hyperplasia adjacent to abutments (11 cases). The most frequent prosthetic complications were phonetic problems in the maxilla only (10 cases), acrylic fractures in bridges (3 cases) and fractures or distortion of the metallic framework (2 cases). The results indicated that treatment with osseointegrated implants (BiotesTM) is a safe method with predictable long-term prognosis for rehabilitation of the edentulous patient.
