ABSTRACT:
A fixture for attaching a dental prosthesis to a dental implant has a base to be received on the implant, and a head attachable to the base. The base has an angled upper surface, and the head has an angled lower surface, the head being selectively rotatable with respect to the base. As a result, the head can be disposed with respect to the base so that the head will always be perpendicular to the gum line, even though the implant is angled with respect to the gum line. A non-round projection on the head engages a non-round recess on the base to prevent rotational movement when the fixture is installed, and a single screw extends through the head, through the base, and into the implant to hold the assembly together.
