Abstract
A dental or orthopedic implant (10, 10', 100, 100', 200) having an abutment receiving bore either with a self-holding taper or threaded is shown which in selected embodiments includes annular epithelial stops (32, 132, 232) to limit epithelical migration. Other embodiments useful as posterior implants or where minimal bone depth is available (100, 100', 200, 300, 400) have a wide body with a shortened length having a length (l) to width (w) ratio of no more than approximately 1.5:1 and configured so that the outer body distributes lateral forces all along the side wall and distal end face (18) abetted in selected embodiments by a load bearing groove (126, 226) in the distal end face of the implant. Osseointegration promoting structures are shown including fins (24), evenly distributed dimples (250) and coatings (302) in selected embodiments.
