ABSTRACT:
Applicator for a dental compound, whose elongate implement body (1, 2) is or can be connected at the front end (3) to a syringe (4) containing the dental compound and has a ram (5) for advancing a plunger contained in the syringe (4), which plunger can be pushed forward by means of a pusher rod (10) protruding out of the rear end of the implement body (1). To avoid the stick-slip effect, the ram and the pusher rod (10) are each connected to a rack (6, 9), between which racks a gearwheel/pinion pair is arranged, which brings about a gear reduction from the pusher rod to the ram.
