It has made it possible to avoid excessive bone cutting without damaging the surrounding soft tissue. Referring to the drawings, the head of the dental contra-angle handpiece and the bone drill attached to it are provided with a coil (2) for controlling expansion and contraction from the insertion opening of the cylinder (1) to the tip of the cover of the bone drill. The cylinder cap (3) plays the role of holding down. With such a structure, it has become possible to prevent the surrounding soft-hard tissue from being damaged and to prevent unnecessary cutting of bone during bone cutting in the mouth.
