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.
Claims2
A dental implant comprising:
- a fixture configured to be implanted into an alveolar bone;
- an abutment fixed to an upper part of the fixture and having a core hole downwardly formed with a predetermined depth in a center of an upper surface of the abutment;
- a crown fixedly bonded to an upper outer side of the abutment and having a passage vertically formed through a center of the crown;
- a cover screw having a screw portion screw-fastened to the core hole and a head portion which comes in close contact between an upper surface of the abutment and a lower surface of the crown, which face each other, to cover the core hole, in which, when the screw portion is released by a tool passing through the passage, the head portion moves up so that the cover screw provides a separating force to the crown;
- a fastening screw which is led into the core hole, and screw-fastened into a fastening hole of the fixture through a through-hole formed in a lower end of the core hole, thereby fixedly coupling the abutment to the fixture;
- and
- an anti-release member provided in the core hole between the cover screw and the fastening screw to prevent the fastening screw from being released.
