PURPOSE: A fixture for dental implant is provided to prevent a nerve from being cut in surgical operation by minimizing an area contacting with the skin of a patient due to the semi-spherical lower side of the fixture and to improve bonding force with alveolar bone. CONSTITUTION: A fixture for dental implant includes a screw part on the outer circumference of the fixture. A polygonal protrusion or a polygonal groove(114) is formed on the upper center of the fixture. A fixing screw is combined with a screw linking hole which is implanted in the alveolar bone. The fixture is used for combining an abutment fixing dental implant. The lower side of the fixture is protrude into a semi-spherical shape to minimize an area contacting with the skin.
