ABSTRACT:
A dental handpiece which can be adapted to different types of rotatable joints without great structural changes comprises a handpiece design having a sleeve-shaped end section which receives an insert part. The insert part has an outer shape that is matched to the interior of the sleeve-shaped section of the handpiece but will have an inner contour which is matched to a particular plug member of a particular type of rotatable joint. Thus, by changing the sleeve insert parts, the handpiece can be modified to receive a different type of plug member of a different type of rotatable joint.
