Description

Device for clinically and accurately loading arch wire torque in orthodontic treatment

Technical Field

The utility model relates to the technical field of orthodontic tools, in particular to a device for clinically and accurately loading archwire torque in orthodontic.

Background

In the orthodontic fixing correction treatment, the movement of teeth in the three-dimensional direction is indirectly controlled through the interaction of an appliance and an arch wire, so that the correction of the teeth is realized. In bending and adjusting archwires, the third sequence of bending can only be accomplished on square archwires, which can be torqued by torque twisting on the square wires, creating a torque force. The torque force is mainly applied to correct teeth to control the movement of the roots so that the roots of the teeth move in the labial (buccal) and lingual (palate) directions; meanwhile, the tooth extraction case can be corrected to enable the tooth to keep the tooth root to move in parallel as much as possible.

At present, common tools for bending and adjusting an arch wire clinically comprise the following components: 1. torque tongs: in clinical torque bending, two torque clamps are usually attached to each other, one torque clamp is held in opposite directions, the other torque clamp rotates towards the lip and the tongue, the rotation angle can be determined according to the needs, the torque is bent, and finally the torque degree is determined by comparing the angle measuring ruler. The manual loading of the torque is most commonly used clinically, on one hand, the loading rotation center is difficult to unify, the accurate loading of the torque is affected, on the other hand, the torque is completely and blindly loaded, no accurate angle calculation and measurement are carried out, the remote comparison angle is simply clamped, and the torque loading angle is not accurate; in the process of clamping and loading, the problems of clamping force of the torque tongs, clamping angles of the torque tongs and the archwire, clamping distances between the two torque tongs, clamping angles between the two torque tongs, relative rotation center offset, fuzzy loading angles and the like are unavoidable and difficult to avoid in clinic all the time. This directly leads to uncertainty in the loading of archwire torque data, thereby affecting the expression of tooth data and even the overall orthodontic efficacy.

2. Square wire torque shaper: for example, patent document No. cn98247301.X discloses a square wire torque former composed of a pair of tools capable of bending a torque in a specified tooth position near and far at a time, and a dial of a specific angle is provided on the tools, and the two tools are rotated relatively to twist a square wire by a desired angle. The torque shaper is manually loaded, and the degree of the dial is compared by visual inspection, so that the torque shaper is not accurate enough; two torques must be loaded simultaneously, and the application is not flexible enough.

3. Novel archwire torque loading device: for example, the invention patent application with the application number of CN201810474387.2 discloses a quick and accurate loading device for arch wire torque, which comprises a cathode semi-ring and an anode semi-ring, wherein square wires can be clamped into grooves of calipers, and the torque is loaded through relative rotation of the cathode semi-ring and the anode semi-ring. The half-ring degree of the loading device is only +/-45 degrees, and larger torque cannot be loaded; the fixing wrapping of the groove of the semi-ring to the arch wire is insufficient, so that the arch wire is easy to pop up and the loading is failed; for archwires of different types, a caliper in the center needs to be pushed and pulled, which is troublesome.
