Abstract:
Endosseous dental implants having generally cylindrical-shaped or tapering bodies and, in some cases, external threads or ribs over a substantial portion of their external surface, may include internal or external wrenchengaging surfaces at the proximal end portion and include, below a relatively smooth proximal end or neck portion, an external transition zone with a rougher surface, and a body portion having greater surface roughness than the transition zone, or, on the body portion, an HA or TPS coating, to promote attachment of the implant to bone tissue when the implant is placed in a passage formed in bone tissue to receive the implant.
