Definitions
- the present invention relates to a handpiece, or contra-angle, used in endodontics.
- the invention proposes to remedy these various disadvantages by proposing an endodontic handpiece, which does not require a change of instrument at each renewal of operation.
- the subject of the present invention is an endodontic contra-angle (1) provided with a head (2) supporting an endodontic instrument (3), and means (5) for fixing a handle. (4) penetrating into the head of the contra-angle characterized in that said head (2) of the contra-angle (1) is provided with a free rotating member (6), fixedly assembled with the body of said head (2). ).
- the contra-angle (1) is provided with a head (2) on which is placed a member (6). The latter will be in free rotation around the head (2) of the contra-angle (1), but will be fixed permanently on the body of the head (2). This allows the rotational movement of the instrument (3).
- the contra-angle (1) is provided with a head (2) made entirely of plastic, constituting a reusable part, and thus limiting the costs.
- the member present on the head (2) of the contra-angle (1) is a pinion.
- this pinion is made of injectable material, such as plastic.
- a root canal blade is fixed on the pinion.
- the pinion is overmolded on the canal instrument blade, thus ensuring the attachment of these two elements.
