ABSTRACT:
A contra angle handpiece of this invention employs a laser beam transmitting glass fiber for dental treatment in such a manner that the transmission of the beam is carried out not by a reflecting mirror, but by a glass fiber centripetally held with respect to the handpiece by means of resilient grip members. As a result, the disadvantages of the prior art such as reflection factor reduction and reflection angle changes, which result from the use of a reflecting mirror in a contra angle dental handpiece, are eliminated.
