The implant has a gingival surface exposed through the overlying gingiva. The orthodontic abutment is capable of receiving an orthodontic component. The orthodontic abutment comprises a generally cylindrical main body having a lower end for engaging the gingival surface of the implant and a supragingival end opposing the lower end for protruding above the overlying gingiva. The main body has an outer surface between the lower end and the supragingival end. The outer surface includes a roughened portion to which the orthodontic component is to be attached and a gingival portion for contacting the overlying gingiva. The gingival portion extends from the lower end for about 3 mm. The roughened portion typically extends 360.degree. around a central axis of the main body and is preferably adjacent to the supragingival end.
