PURPOSE: A fixture driver used for a dental implant is provided to enable a user to very efficiently operate the fixture without using a mount, to obtain profitability, and to prevent the combination of the fixture and alveolar bond from being damaged. CONSTITUTION: A fixture driver used for a dental implant includes a head unit(101), a shank unit(102), and a handpiece joint(103). The head unit comprises a polygonal groove(10) having a leading end in which a polygonal protrusion is fitted and a cylindrical supporting unit(20) which is extended along a central axis of the polygonal groove and is inserted into an inner screw of the fixture. The supporting unit positions a U-shaped elastic member between two semi-pillars.
