摘要：
A dental handpiece or elbow having a guide sleeve for mounting a dental treatment tool, in which the inner annular surface of the guide sleeve is coated with a wear-resistant coating so as to enhance the strength thereof against hammering and radial forces generated during use of the handpiece. In the case where the sleeve is connected to the tool through the intermediary of a collet, the latter is also provided with a similar coating in at least the regions in contact with the guide sleeve.
