ABSTRACT:
In order to provide a surface in a gripping region of a dental handpiece that meets the requirements of being optimally smooth for hygienic reasons and also to provide an adequate non-slip surface, the dental handpiece has a plurality of thin lines arranged in line patterns having a roughened surface in the gripping portion. These lines or line patterns extend in a longitudinal direction and may have portions that extend at an angle to the longitudinal portion, and these patterns are arranged at least in two quadrants of the circumference of the grip part that preferably lie diametrically opposite one another.
