PURPOSE: Provided is an impact tool for dental technology which detaches processed teeth by simply pushing, thereby applying an impact to a fixing pin, without deformation of the processed teeth. CONSTITUTION: The impact tool includes a main cylindrical tube; a piston tube; a return cylinder; a piston; a return spring; and an impact pin. The main cylindrical tube has an open front end and a closed rear end. The piston tube forms a whole body along with the main cylindrical tube. The return cylinder resiliently moves in the main cylindrical tube by an impact spring. The piston is inserted into the return cylinder. The return spring is disposed between the main cylindrical tube and the piston. The impact pin is slidably inserted into the piston tube.
