<p>The present invention relates to an abutment coupled to a fixture, and more particularly, to an abutment in which a gum coupling part is eccentric so that the fixture is eccentrically implanted. The abutment according to the present invention includes: a fixture insertion part; and the gum coupling part. The fixture insertion part is inserted into the fixture and coupled to the fixture. A central axis of the gum coupling part is eccentric to be dislocated with a central axis of the fixture insertion part. The gum coupling part is disposed on an upper portion of the fixture insertion part and inserted into the gum. Also, in the abutment, an eccentric line for checking an eccentric amount may be disposed on an upper end of the gum coupling part. The abutment may further include a denture coupling part disposed on the upper portion of the gum coupling part so that the denture is coupled. According to the present invention, the abutment in which the gum coupling part is eccentric is provided. Thus, the denture coupled to the abutment may be disposed at the center even though the fixture is eccentrically implanted into an alveolar bone. Also, since the gum coupling part is disposed at the center, the gum coupling part may be disposed right under the denture to support denture. Therefore, the abutment may prevent the denture from being spaced apart from the gum.</p> |
