Abstract
Abstract An apparatus and method is disclosed for an improved rotary dental implant post for supporting as prosthesis in a patient, comprising as boss having a boss hole defining a boss hole recess. A prosthesis support is secured to a stud with the stud having a stud projection. An undercut is defined in the boss enabling the stud projection to be moved along the bore hole recess and to enter the undercut for enabling free rotation of the support relative to the boss. In one enbodiment of the invention, the stud projection comprises threads disposed on the stud for mating engaging with threads defined in the boss hole. In another embodiment of the invention, the stud projection comprises a key expending from the stud for mating engaging with a keyway defined in the boss hole.
