Abstract
The adjustable support for a prosthetic tooth includes an abutment member having an opening for reception of a bolt member that engages with a nut member. The abutment member is sandwiched between a head portion of the bolt member and an enlarged collar portion of the nut member. The engaging surfaces between the head portion and the abutment member and between the abutment member and the enlarged collar portion of the nut member are of complementary shape with respect to each other to permit pivotal adjustment of the abutment member with respect to the bolt and nut members. The abutment member is thus pivoted to a desired position and the bolt and nut members are tightened to lock the abutment member in the desired position. A prosthetic tooth having an opening of complementary shape with respect to the abutment member engages the abutment member to assume the angular orientation of the abutment member. The adjustable support and prosthetic tooth are affixed in a foundation implant that is locked into the jawbone. The prosthetic tooth and the adjustable support are thus rigidly secured to the jawbone.
