Abstract
The invention relates to a dental tool having a shank region, which is formed for coupling to a dental handpiece, and also having a work region, which is connected to the shank region. In this case, the shank region of the dental tool is formed so that there is the possibility of latchable insertion and removal without actuation. In particular, at least the shank region can consist of plastics material. As a result, inter alia facilitated handling of the tool and inexpensive production of the tool are rendered possible.
Claims18
A dental tool comprising:
- a shank region configured to be coupled to a dental handpiece, wherein the shank region includes an annular latching recess;
- a work region coupled to the shank region;
- and
- a carrier region having an angular, polygonal, outer periphery, wherein the carrier region is configured to engage a drive component of the dental handpiece and is configured for form-lock coupling to the drive component such that the dental tool is configured to be rotated about the longitudinal axis at the carrier region via the drive component;
- wherein the shank region is configured to be latched into the dental handpiece, and inserted and removed from the dental handpiece without actuation of any element on the dental handpiece;
- wherein the shank region, including the annular latching recess, is sized and shaped to be latched and snap-fit into the dental handpiece along the longitudinal axis, such that the annular latching recess engages a portion of the dental handpiece to releasably secure the shank region to the dental handpiece.
