WIPO Patent Application WO/2011/139029
Kind Code:
A2
Abstract:
The dental screw of the present invention includes a head part having a tightening groove for transmitting the torque of a driver, and a screw part having a screw thread in the longitudinal direction, wherein the head part further includes a fixing groove at the central portion of the tightening groove to prevent the screw from disengaging from the driver. The dental driver of the present invention is a dental screw driver including a tightening part and a supporting part, wherein the tightening part includes a tightening projection which fits into the tightening groove of the dental screw, and a fixing tip disposed at the tip of the tightening part so as to be inserted into the tightening groove. According to the dental screw and driver of the present invention, the screw rarely disengages from the driver when the screw is being tightened into or removed from an oral cavity, and unexpected accidents caused by a stray screw may be prevented during dental surgical procedures, such as those involving implants and orthodontia.
