Subperiosteal dental implants are not intended to replace conventional dentistry but provide an alternative method of treatment for the patient who cannot otherwise tolerate a dental prosthesis. Success can be achieved in the maxillae and in the mandible without the risk of serious complications. There are good prospects for a long-term favorable prognosis when appropriate surgical and prosthodontic criteria are observed.
The results of this preliminary evaluation of a tooth implant model combining a stylized tooth root design and a thin, highly biocompatible microporous carbon coating, although tentative, add support to the feasibility of developing a statisfactory system for the immediate replacement of selected teeth in healthy bone.
32 carbon coated tooth replicas were implanted in the jaws of 8 mongrel dogs for periods ranging from 3 months to 2 years. Fourteen of 16 molor implants and 10 of 16 premolar implants had 0.5 min. of mobility or less. Histology of specimens from 4 dogs sacrificed at 3 months showed new bone directly in contact with the implant surface.
22 implants have been carried out in the mandibular arches of 5 dogs for the purpose of assessing the usefulness of a special isotropic carbon coating on vitallium cast dental replicas. Clinico-radiological, histopathological and microradiographic data showed the usefulness of the coating. Permucous acceptability, which is hard to obtain with other materials, proved satisfactory. Anchorage of the replicas to the surrounding bone was good, thus confirming the compatibility and usefulness of the isotropic carbon coating.
