Abstract
A dental handpiece which can receive one of a number of vibrating instruments for applications in endodontics or periodontal treatment includes an elongate handpiece for defining a body enclosing a non-rotating axle excited mechanically in vibration, mounted in the body by semi-flexible supports which contribute to generating and localizing a vibration node towards the front of the handpiece and to retain the vibrating axle centrally with its housing. A flexible interconnection is provided between the axle and the rotating driven shaft of the operating motor, to develop the vibrations which are desired.
