Medical or dental-medical treatment instrument having a filter element

The invention relates to a medical, in particular dental-medical handpiece ( ) having a rod-shaped grip part in the forward end region of which there is arranged a holding device ( ) having a lateral insertion opening ( ) for a working tool ( ), whereby the middle axis ( ) of the insertion opening ( ) includes, with the middle axis ( ) of the grip part extending rearwardly from the point of intersection with the middle axis ( ), an obtuse angle (W ). In order to improve the suitability of the handpiece ( ) also for use in small spaces of the body to be treated, a forward grip section ( ) of the grip part is curved towards the side ( ) of the handpiece ( ) away from the insertion opening ( ), and the obtuse angle (W ) is smaller than 103&deg; and greater than 95&deg;.
