Studies have been conducted concerning the development of improved, high-density, high-strength grooved alumina tooth root structures of the nonbifurcated design for monkey and human implant studies. Biomechanical stabilization of the implants in a tooth socket is achieved by bone ingrowth in the deep surface grooves of the implant as well as the surface roughness of the alumina. These two factors conceivably provide a mechanical interlock between the bone and the ceramic. Once stable within the jaw, these devices then allow for attachment of prosthetic devices. Implant studies have shown that immediate attachment of crowns and roots into fresh extraction sites has not been a successful method. However, implantation of the root, allowing time for ingrowth, and then attachment of the prosthetic device appears at this time to be the method of choice. Author
