ABUTMENT SCREW FOR IMPLANT

摘要

PURPOSE: An abutment screw for implant is provided, which can easily release or couple an abutment screw using a linear type tool even though a hexagonal tool wrench groove is worn away. CONSTITUTION: An abutment screw for implant comprises: a fixture(4) which is implanted in the alveolar bone; an abutment(6) in which the dental implant is fixed to the top; and an abutment screw(10) which coupled the fixture and abutment. In the fixture implanted in the alveolar bone, a screw thread is formed in the outside and a hexagon head part is formed in the top. In the abutment combined with the top of the fixture, a bonding groove is formed so that the hexagon head part of the fixture can be inserted in the bottom.
