Abstract
A dental handpiece carries a drill and drives it in relative motion in a direction of penetration. The handpiece includes a body with a proximal end and a distal end, a removable head connected to the body's distal end, able to hold the drill, abutment means fixed on the dental handpiece by fixation means and able to limit the depth of penetration of the drill in the body of a patient. The abutment means, protruding from the dental handpiece, are fixed and locked on the dental handpiece by locking means which are actuated by the simple movement of joining the head to the body.
