Embodiment Construction

[0062] exist figure 1 The dental hand tool 10 shown in FIG. 2 has a handle 12 which is partly corrugated 14 in a manner known per se. The grooves serve for better grip and corresponding handling.

[0063] In the exemplary embodiment shown, the dental hand tool 10 is designed for use on both sides, so that two connecting parts 16 and 18 protrude from the handle 12 at the end sides. A connecting element 20 or 22 is respectively connected to the connecting element. The coupling elements each have a ring 24 or 25 . There is thus an essentially centrosymmetric shape, the connecting parts 16 and 18 each having a bend 26 and 28 which differ slightly from one another.

[0064] Such different curvatures are known per se and serve to improve ergonomics when operating in inaccessible places in the patient's mouth.

[0065] The connection elements 16 and 18 essentially have a slightly conical configuration as viewed in their course. The bends on each connector are oriented opposite e...

Abstract

The invention relates to a dental hand tool, which is provided with a handle comprising at least a connector and a coupling member at one end thereof. The dental hand tool is in particular provided with a second connector and a second coupling member at the other end of the handle. A modeling tip that comprises a shaft is provided, suitable for the coupling member. The modeling tip comprises a coating of a material that is more flexible compared to the remaining material of the modeling tip. In particular, the material has a smaller surface energy compared to the remaining material of the modeling tip.

Description

technical field [0001] The invention relates to a dental handpiece according to the preamble of claim 1 . Background technique [0002] Dental hand tools, also known as dental hand instruments, have been known for a long time. Such hand tools are either integral or have replaceable heads, such as styling heads. The head is usually curved, for example in the form of a swan-neck, so that the dentist can also treat positions facing away from the mouth opening of the patient, that is to say in the distal region of the teeth or between the teeth of the molars. The position in is processed. [0003] It has long been known that maneuverability can be improved by differently curved heads, it is also known here to implement heads for different purposes, that is to say for example to provide spoon-shaped heads, shovel-shaped heads, For filing the head end, etc., in order to be able to take into account the different necessary procedures performed by the dental practitioner. [000...
