The implant has a first locking part (33) formed at least in a part of a head (32) of the abutment screw and a seat hole formed in the abutment with such a depth that the head of the abutment screw sinks in and provided with a second locking part (22) formed at least in a part thereof, and the space between the first locking part (33) and the second locking part (22) in the seat hole is filled with filler (4, 5), thereby preventing the abutment screw (3) from being loosened. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
