Problems solved by technology

[0006] In this way, since different equipment is used and different processing methods are used to perform work, it is necessary to temporarily remove the equipment from the equipment and transport it to another place between each work, increasing the number of steps and time, and causing an increase in production costs.

Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0027] figure 1 It is a figure which shows the dental endodontic instrument of this invention, (a) is a top view, (b) is a cross-sectional view. The dental endodontic instrument 10 is composed of a rod-shaped main body 11 made of metal and a handle 12 made of synthetic resin. Moreover, the main body part 11 is equipped with the working part 11a and the coupling part 11b.

[0028] The working part 11a is formed in a tapered tapered shape to be inserted into the root canal during use. Therefore, it is flexible in such a way that it can deform along the root canal. in addition, figure 1 The dental endodontic instrument 10 shown is an example of a plugger, and the front end of the working part 11a is flat, but in the case of a dilator, the front end is sharp. However, in the present invention, it is not necessary to distinguish between a dilator and a filler, and any...

Abstract

Disclosed is a dental root canal treatment instrument having a simplified manufacturing process involving manufacturing the work portion and the joint portion by means of the same processing method. A metal rod-form body (11) has a work portion (11a) forming a fine taper which is inserted into the root canal when used and a joint portion (11b) connected to the thick-diameter end of the work portion and embedded in a handle (12), wherein the work portion and the joint portion are formed by the same processing method. The dental root canal treatment instrument (10) is completed by forming the handle (12) by injecting a synthetic resin to cover the joint portion (11b). The bond between the joint portion and the handle can be reinforced by adding at least one protrusion or recess to the joint.

Description

technical field [0001] The present invention relates to a dental root canal treatment instrument used when cutting the inner wall of the root canal or filling in filling materials in root canal treatment of teeth and a manufacturing method thereof. Background technique [0002] Root canal treatment of teeth refers to the treatment of lesions at the root of the tooth by removing bacteria-infected dentin and nerves with a root canal treatment tool such as a reamer or file. [0003] Figure 4 A perspective view of a conventional hand-held dental endodontic instrument (reamer) is shown. The reamer 20 has a metal main body 21 and a handle 22 made of synthetic resin, and a working part 21a on the front end side of the main body 21 serves as a cutting tool. Then, when the operator pinches the handle 22, inserts the operation part 21a into the root canal from the front end, rotates and pushes and pulls, the inner wall is cut and the root canal is enlarged. Here, the root canal tre...
