Abstract
A prosthetic dental implant which is surgically implantable in the maxillary and mandibular alveolar bones, providing a support base with a protruding post to which one or more prosthetic crown replacements are to be mounted. The implant is a high purity, high density, low porosity unitary alumina body having a serrated base. Its integral top is formed to provide an upwardly extending post with a truncated ellipsodially conical configuration for the attachment of a prosthetic tooth crown. The serrated side walls of the base are formed with outwardly projecting protrusions. These protrusions have a serrated or saw toothed cross sectional configuration with alternating horizontal surfaces and downwardly and outwardly tapering oblique surfaces.
