| 摘要 |
The present invention relates to an implant fixture which enables a smoother implantation process corresponding to the condition of an alveolar bone and has improved implant constitution by improving a thread surface structure providing implant coupling force with an alveolar bone for a more stable and solid implant condition than the initial stage. To this end, the present invention discloses an implant fixture implanted inside an implant groove formed on an alveolar bone by forming a screw part on the outer surface of a fixture body. A functional protrusion is formed on the screw part with one or more radial points of the outer surface of the fixture body. The functional protrusion is configured for smooth insertion during implantation and to prevent reverse rotation after implantation by being formed to have an upward slope from front to rear in the rotation direction during implantation. |
