<p>The present invention relates to a driver for dental implant operation. The driver comprises: a shaft and a rotating body orthogonally inserted into a housing having an inner space formed therein and operating through gear engagement therebetween; a control knob formed on the distal rear end of the shaft exposed from the housing; and a bit formed on an exposed portion at the lower end of the rotating body. As such, the driver can easily and simply fasten or unfasten a bolt while rotating the bit inside an oral cavity by rotating the control knob outside the oral cavity. Therefore, the present invention can minimize the height of the tool. Moreover, even in cases where the space which can be ensured in the impression taking process is considerably narrow, the driver can fasten or unfasten a coping bolt in an easy and simple manner, using the control knob outside the space, after insertion of the tool into the coping bolt.</p> |
