Pneumatic handpiece. The instrument can be used for prophylaxis procedures or bone surgery with the aid of the range of KaVo/Komet Inserts. The power of vibrations can be adjusted with a rotating ring, making the prophilaxis more flexible and accurate. The handpiece connection is fully compatible with the GYROFLEX/MULTIflex rapid couplings (Multiflex is a registered trade mark of Kaltenbach&Voigt & CO. GmbH, Germany). The handpiece can also be used together with the new SONOSURGERY STERIL rapid coupling.
