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.

Independent Claims | See all claims (16)

  1. 1. For use in the mouth of a patient having an endosseous dental implant fixture or the like installed in the patient's jawbone at an edentulous site, a prefabricated dental crown analog having an exterior size and contour to approximate the dimensions and shape of a natural tooth at said site, and an orthodontic wire anchor consisting essentially of hollow tubular means providing an intergral passage extending measially-distally through said analog closer to one of the exterior buccal or lingual surfaces than to the center thereof, for passage of an orthodontic wire through said passage whereby said wire may be anchored with said crown analog.
  2. 13. For use in the mouth of a patient having a dental implant fixture installed at an edentulous site, the combination of a prefabricated dental crown analog having exterior size and contour to approximate the dimensions and shape of a natural tooth at said site, and hollow tubular means providing an integral passage extending mesially-distally through said analog closer to one of the exterior buccal or lingual surfaces than to the center thereof for passage of an orthodontic wire therethrough, an abutment post adapted to be fixed at a gingival end to said implant fixture so as to extend supragingivally from said implant fixture, said analog having a bore opening through its gingival end sized for receiving said post therein, and means traversing said post intermediate its ends for interlocking said post with a side-wall of said analog to fix said analog over said post.
