Abstract
A dental or surgical handpiece which operates on the basis of laser includes a light guide for the laser which, in order to ensure the relative rotation between supply hose and handpiece, is arranged concentrically in the coupling between the supply hose and the handpiece. The light guide of the supply hose extends in one piece into the handpiece and, starting from the coupling with the supply hose, the light guide is displaced increasingly eccentrically toward the inner side of the bend of the angle piece, and the end of the light guide is rotatably mounted in a receiving unit of the handpiece.
