Problems solved by technology

[0002] Conventional root canal treatment preparation files bend the turning line of the preparation file in the plane, and only one curved point contacts the tooth root canal during work. The working area is small, and it is not easy to remove impurities in the root canal, and the contact point is easy to wear and break , short life; in view of such defects, it is necessary for us to design 3D root canal treatment preparation files

Abstract

The invention discloses a 3D root canal therapy preparation file. The preparation file comprises a helix cone, a preparation file rod body, a limiting pad, a handle and a mounting hole, wherein the mounting hole is formed in the center of one end of the handle, one end of the preparation file rod body is inserted into the mounting hole, the preparation file rod body is provided with the limiting pad on the end side, where the mounting hole is formed, of the handle, the limiting pad sleeves the preparation file rod body, a helical groove is formed in the other end of the preparation file rod body, the helical groove is of a 3D helical structure, an initial section of the helical groove is a circular cone, and the tail end of the helical groove is the helical cone; and the helical cone and the preparation file rod body are nickel-titanium alloy material components, and the helical taper of the preparation file rod body is between 0 degrees and 15 degrees as a whole. The preparation filecan thoroughly remove all residues and impurities in the irregular inner cavity of tooth root canals and is long in service life.

Description

technical field [0001] The invention relates to the technical field of tooth root canal treatment, in particular to a 3D root canal treatment preparation file. Background technique [0002] Conventional root canal treatment preparation files bend the turning line of the preparation file in the plane, and only one curved point contacts the tooth root canal during work. The working area is small, and it is not easy to remove impurities in the root canal, and the contact point is easy to wear and break , short life; for such defects, it is necessary for us to design 3D root canal treatment preparation files. Contents of the invention [0003] The purpose of the present invention is to provide a 3D root canal treatment preparation file, which can completely remove the residues and impurities in various parts of the tooth root canal cavity with a long service life. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005...
