Abstract
Endosseous dental implants having generally cylindrical-shaped bodies and self-tapping threads at the distal end and, in some case, external threads over a substantial portion of their external surface, include internal or external wrench-engaging surfaces at the proximal end portion and, between the relatively smooth distal and proximal end portions, an external middle region having greater surface roughness than the proximal or distal ends, or a coating, to promote attachment of the implant to bone tissue when the implant is placed in a generally-cylindrical passage formed in bone tissue to receive the implant.
