Abstract: A submergible, post-type dental implant system for anchoring an artificial crown or bridge in a row of teeth or edentulous or partially edentulous area includes a root structure which is surgically implanted transgingivally and into the bone therebeneath, an implant head which is compatibly sized and shaped to fit over an upper tapered portion of the root structure. Prior to the assembly of these two titanium alloy components, a healing cap is disposed over the tapered portion of the root structure during the time interval for healing which may be as much as three to six months. After the healing period has ended, a tool is used to remove the healing cap and thereafter the implant head is aligned and slid over the top tapered portion of the root structure.

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.
