Abstract:
PCT No. PCT/JP83/00161 Sec. 371 Date Jan. 16, 1984 Sec. 102(e) Date Jan. 16, 1984 PCT Filed May 26, 1983 PCT Pub. No. WO83/04175 PCT Pub. Date Dec. 8, 1983.A dental tool is provided for extracting a tooth which is secured to an alveolar bone through a pericementum. The tool includes an elongate, flat and thin blade operatively connected to an acoustic transducer which produces ultrasonic vibrational energy. The blade has a thickness on the order of about 0.2 to 0.5 mm which is substantially less than the thickness of the pericementum to enable the blade to and cut through the pericementum located between the tooth and the alveolar bone along the profile of the tooth under excitation by the acoustic transducer. The blade transmits ultrasonic oscillation to the tooth so as to insensitize the pain transmitting system of the tooth. The pericementum is effectively cut with a reduced average cutting resistance while the insensitization is maintained.
