Abstract
The invention relates to a dental preparation instrument that includes a tool that rotates in an alternately reversible manner. The preparation instrument has a drive for the tool. The drive provides a continuous fully rotational motion, and a gearing is arranged before the tool. Said gearing converts the continuous fully rotational motion of the drive into an alternately reversing rotational motion, which is continuous as viewed over several reversals.
