ABSTRACT:
A two part abutment system (50,50' and 64,64',64") is shown for use with a root member (10) implanted in the alveolar bone (16) particularly suited for use when the root member (10) is not positioned sufficiently deep within the the bone to thereby expose portions of the root member. The abutment member (50,50') is formed with a root member shoulder receiving seat in communication with a bore having at least a portion with a non-circular surface. A post (64,64',64") having a non-circular head (66) having a shape conforming to that of non-circular portion of the bore and a shank (68) extending therefrom is received through the bore into the socket (28) of the root member (10). Suitable locking means such as cement is used to fix the abutment to the root member. An adaptor (70, 70') is shown for converting a root member (74) having a threaded bore (72) for use with the two part abutment system of the invention. A modified post (84) is show having first and second locking tapers for reception in bores having matching locking tapers formed in the root member and abutment member, respectively.
