PCT No. PCT/EP95/00710 Sec. 371 Date Aug. 28, 1996 Sec. 102(e) Date Aug. 28, 1996 PCT Filed Feb. 27, 1995 PCT Pub. No. WO95/22938 PCT Pub. Date Aug. 31, 1995For ultrasonic preparation of hard or soft tissues or of tissue replacement material a apparatus is proposed comprising a hand piece (10), which includes an ultrasonic vibration generator (16), an ultrasonics deflecting head (28) as well as a tool (36) carried by the output member of the deflecting head. An abrasive treatment medium (48) is supplied to the working region defined between the tool (36) and the material (66) to be prepared. Thus even in places, which are difficult to access, cavities can be produced in dental or bone tissue in a gentle and precise manner.
