[Endosseous aluminum oxide-ceramics implantations. The activities of a work group sponsored by the county government of Baden-Württemberg].

Emanating from the recognition of the favourable body tolerance of some ceramic substances in the U.S.A., investigations were started in 1970 with a view to the possibilities to improve endoprosthesis of joints by the use of Al2O3 ceramics. The experience collected brought a new insight into bio-mechanically based reactions occurring in osseous tissue bordering the implant. Their use in tooth implants led to corresponding adaptations of implant forms.
