Document Type and Number:
WIPO Patent Application WO/2019/132529
Kind Code:
A1
Abstract:
The present invention relates to a dental implant, comprising: a fixture implanted into an alveolar bone; an abutment which is fixed to the top of the fixture and has a core hole downwardly formed with a certain depth in the center of the upper cross section thereof; a crown which is bonded and fixed to the outside of the top of the abutment and has a passage hole formed in the center thereof so as to vertically penetrate the crown; and a cover screw configured such that a screw part is screw-coupled to the core hole and a head part comes into close contact between the upper surface of the abutment and the lower surface of the crown which face each other so as to block the core hole, and that when the coupling of the screw part is released by means of a tool that has passed through the passage hole, the head part rises and a separation force is provided to the crown. Accordingly, the present invention has the technical effect of facilitating the separation of the crown and preventing weakening of a coupling force, thereby enabling efficient surgery and management.
