Problems solved by technology

Since the root filling depends on the smooth needle body of the "root filler" to press the gutta-percha tip through the side and deliver it in place, although the work of delivering the gutta-percha tip in the slender tooth root canal can always be completed in the end However, because the dental surgical instrument "root filler" that transports the gutta-percha tip in place is not easy to use (it is inconvenient to adjust the forward and backward transport), the operation will be quite troublesome

Embodiment Construction

[0010] Fig. 1 illustrates the structure of the prior art "root filling device": a special dental instrument composed of a cylindrical smooth needle body 1 and its needle handle 2, transporting the gutta-percha tip to the elongated tooth root canal It is mainly achieved by the contact friction force between the cylindrical smooth needle body 1 and the gutta-percha tip. Since the friction force between the two is very small, it is difficult and troublesome during the entire conveying process. . Only when the root filler is pulled out from the gap between the root canal of the tooth and the gutta-percha tip, due to the smoothness of the smooth needle body 1, there is little friction with the gutta-percha tip, which can avoid bringing the gutta-percha tip out of the tooth again root canal.

[0011] Fig. 2 illustrates the improved structure of the present invention: in order to increase the frictional force between the root filler and the gutta-percha tip, by setting serrations on...

Abstract

The invention discloses a special dental operation apparatus in a root filling treatment as well as a manufacturing method thereof. The invention relates to an improvement to the 'root-filler' structure of the existing dental operation apparatus for solving the trouble of feeding a gutta-percha point in the slender root tube of a tooth during the operation process of a root tube treatment as a manufacturing method of an apparatus for realizing the improvement. The invention is characterized in that the side surface of the circle of a needle body (1) is respectively provided with a sawtooth side surface (3) and a smooth side surface (4); besides, the sawtooth side surface (3) on the needle body (1) with large friction force is used for bearing the forward-backward displacement regulating motion during the process of feeding a soft gutta-percha point in place in the tooth tube of the tooth; while the smooth side surface (4) is contacted with the soft gutta-percha point to lead the needle body (1) to conveniently slide away from the gutta-percha point and to be conveniently pulled out from the root tube of the tooth.

Description

technical field [0001] The invention relates to a root filling surgical instrument technology used in dental root filling therapy and a preparation method thereof. Background technique [0002] Root filling therapy in the process of dental root canal treatment, the special dental surgical instrument used is commonly known as "root filling device", which is composed of a round smooth needle body and a hand-operated needle handle connected to it. During treatment, after the nerve in the root canal is removed, when it is necessary to send the soft gutta-percha point as a filling into the root canal of the tooth to be treated, it is necessary to use the above-mentioned special dental instrument "root filler" to complete the root canal. Surgical procedure. Since the root filling depends on the smooth needle body of the "root filler" to press the gutta-percha tip through the side and deliver it in place, although the work of delivering the gutta-percha tip in the slender tooth ro...
