Abstract:
1. An implant comprising: an implant body in which a fitting hole portion having a taper shape, an inner diameter of which is reduced over a depth direction, is formed in a portion of a central hole; an abutment having a fitting shaft portion having a taper shape, which is fitted into the fitting hole portion; a clamper pin which is inserted into a through-hole formed along the axial direction of the abutment and has a co-rotation restriction shaft portion that is engaged with a co-rotation restriction hole portion formed in the central hole of the implant body such that rotation of the clamper pin around a central axis of the clamper pin is restricted; a lock nut which has an external thread that is screwed in an internal thread formed at a portion of the through-hole of the abutment and an internal thread that is screwed in an external thread formed at a portion of the clamper pin and which moves the clamper pin relative to the abutment; and a clamper which is interposed between the clamper pin and the central hole of the implant body, and engaged with a separation prevention shaft portion of the clamper pin and a separation prevention hole portion of the implant body as the clamper pin moves relative to the abutment, thereby restricting relative movement between the clamper pin and the implant body.
