Abstract:

The present invention relates to an abutment and crown coupling structure for an implant. To this end, the present invention relates to an abutment and crown coupling structure for an implant, the structure having a lower part of an abutment facing and coupled to, by a bolt, the upper part of a fixture coupled to a tooth-extraction hole of the alveolar bone, and having a lower part of a crown inserted into and coupled to the upper part of the abutment, wherein the abutment has: a support stepped part formed along the edge at the lower part of an abutment body having a stepped hole; a crown supporting guide formed along the edge of the abutment body from the inner upper part of the support stepped part; and an inclined groove part formed at the upper part of the abutment body, and the crown has: an abutment insertion groove, of which the lower side is open, formed at a crown body; a hanging stepped part formed at the edge of an inlet side of the abutment insertion groove; a shock-absorbing layer provided on the inner surface of the abutment insertion groove; and an inclined protrusion part integrally formed at the bottom surface of the inner upper part of the abutment insertion groove. Therefore, the present invention can prevent shock from being transmitted to the abutment through the crown, thereby minimizing a feeling of unfamiliarity, and can reuse the implant since only the resin inserted into a contact part of the crown is separated and new resin is filled therein.
