Abstract: A dental implant includes a fixture implanted into an alveolar bone, an abutment fixed to an upper part of the fixture and having a core hole formed in a center of an upper surface of the abutment, a crown bonded to an upper outer side of the abutment and having a passage vertically formed through a center of the crown, and a cover screw having a screw screw-fastened to the core hole and a head in close contact between an upper surface of the abutment and a lower surface of the crow to cover the core hole, in which, when the screw is released by a tool passing through the passage, the head moves up so that the cover screw provides a separating force to the crown. The dental implant may facilitate a separation of the crown and prevent binding force from weakening, thereby enabling an efficient procedure and management.
