Description

Technical Field

[0001] The invention relates to the field of dental medical treatment, in particular to a square wire arch torque bending and measuring tool. Background Art

[0002] With the in-depth research on personalized lingual brackets, indirect bonding technology of brackets, and prefabricated lingual archwires, lingual orthodontics is becoming more and more prosperous. When applying lingual self-ligating brackets clinically, orthodontists choose self-ligating brackets with appropriate torque according to the type of case and the correction plan. When the correction enters the square wire arch stage, orthodontists may need to perform specific torque operations on the square wire arch according to the current patient's situation to generate the required torque force, and through the synergy of the archwire and bracket, control the root movement, thereby achieving better correction effect. In concept, adding torque to the archwire is the labial (cheek) and lingual (palatal) twisting of the archwire segment of individual teeth. When the square wire arch is inserted into the bracket, the crown will move in the direction of the archwire twisting, while the root will move in the opposite direction. At present, adding torque to square archwires is one of the difficulties in personalized lingual correction. Since personalized archwires have many bends and the distance between bends is short, they are not easy to operate and require high experience from doctors or technicians. In addition, during the operation, it is impossible to ensure that the non-bent section will not be deformed and whether the bending torque meets the requirements.

[0003] When bending the square wire arch torque, doctors or technicians usually use two torque pliers to clamp the square wire and twist it. The arch wire is twisted to obtain a square wire with torque. Theoretically, the twisting of the square wires on both sides clamped during bending must be concentric. If the hands exert up and down or front and back forces during twisting, the square wire will bend in different directions. In actual operation, it is difficult to keep the overall arch shape or the plane of the arch wire unchanged while bending the torque. It is also necessary to compare the arch wire with the arch wire diagram to see if the arch shape has deviated and to check whether the arch wire plane is on the same plane. If so, the arch shape or the arch wire plane needs to be adjusted. The operation is cumbersome and takes a lot of time. Summary of the invention
