Implanting screw force applying device for correction in dental orthodontics and using method thereof

Abstract

The invention discloses an implanting screw force applying device for correction in dental orthodontics and a using method thereof. The implanting screw force applying device comprises an implanting screw, a towing hook and a towing rope. The implanting screw comprises a screw segment, a cylinder segment and a towing hook connecting segment, and the screw segment, the cylinder segment and the towing hook connecting segment are connected in sequence end to end. The towing hook connecting segment is provided with a ring slot, and a through hole is formed in the bottom of the ring slot in a penetrating mode. The implanting screw force applying device is reasonable in structure design, the towing hook and the implanting screw are matched for use, the implanting screw force applying device is made of thicker stainless steel, the rigidity is high, the implanting screw force applying device provides a good support in the process of applying force, a ligature wire is added in the neck of the implanting screw and fixed, that is, the part, penetrating the hole of the implanting screw, of the towing hook and the upper wall part of the neck of the implanting screw are locked, the towing hook and the implanting screw form a firm union and are not prone to shaking or rotating left and right, and in addition to being able to withstand vertical and forward-backward forces, the force applying device can further withstand left-right force.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a force applying device for orthodontic implant nails in orthodontics and an application method thereof. Background technique [0002] In orthodontics, it is very difficult to achieve the depression and movement of teeth by conventional methods, which may easily lead to the elevation and movement of anchorage teeth, which will bring adverse effects or relapse easily even after overbite treatment of anterior teeth. Now, with the clinical application of implant screws, the use of implant screws to depress the anterior teeth can achieve the depressive movement of the teeth. However, what troubles orthodontists is that the positioning of the implant screws is difficult due to the narrow distance between the roots of the anterior teeth. , Implantation nails are easy to damage the root of the tooth or because the implant nail is too close to the root of the tooth and the tooth ...

AI Technical Summary

Problems solved by technology

In this way, there is a greater safe distance between the implant nail and the tooth root, but under this method, the force of the implant nail has become a problem that needs to be better solved

The conventional method is to use the ligature wire to wrap around the neck of the implant nail and tighten it to fix it. The ligature wire extends out of the mucosa and is bent into a traction hook for extra force. This kind of traction hook is soft, not rigid, and lacks support. Oppresses and damages the gums, which is not conducive to changing the position and direction of the force
