Abstract
A dental implant for anchoring in bone, wherein said bone comprises an outer cortical bone section and an inner cancellous bone section is made of a body of resorbable material such as coral, having a portion capable of being wedged into the cancellous bone. The body of coral has a generally cylindrical root portion, an emergent portion capable of being wedged into said outer cortical bone section, and a transgingival coronal portion being sized to extend beyond said emergent portion to end beyond a gingival layer, and an abutment portion and a head for retention of said prosthetic device at the other end, wherein said abutment portion meets said coronal portion at an interface beyond said gingival layer. The body of coral is substantially electroplated with a suitable plating material such as gold. At least some of the root portion is absent said plating material so as to allow the bone to enter the substantially plated body of coral to resorb and replace at least some of the coral.
