[Experimental evaluation of apatite coated implants prepared by the build-up technique].

Abstract

In this study, apatite coated subperiosteal and endosseous implants were prepared by the build-up technique, that is, dental alloy was cast in the required shape, and a covering of glass was fused onto it. Then hydroxyapatite powder was coated on the surface of the glass coat and hydrostatically pressed to form a compact layer which was then heated. These implant materials were tested by animal experiment to evaluate the applicability for clinical use. The results suggested that endosseous subperiosteal implants are available for maxillary molar parts.
