Abstract
A dental crown analog suitable for orthodontic anchorage mates with an endosseous dental implant fixture to provide such anchorage at an edentulous site. The crown analog is tapered down toward the transverse dimensions of the implant fixture above the gun line, to minimize the accumulation of bacterial plaque, and to facilitate cleaning by the patient during the process of orthodontic therapy. A standard abutment fixed to the implant fixture may be used with a dental crown overlay fitted over the abutment to provide a choice of crown sizes and shapes.
