A high-precision square wire torque forming device

Abstract

A high-precision square wire torque forming device, including a worktable, a torque scale plate and a rotating plate are installed on the worktable, the torque scale plate has a scale showing the torque angle of the square wire, and the rotating plate is used to rotate the square wire Make square wire torque forming. The beneficial effects of the present invention are: the square wire has high torque accuracy, can obtain a completely accurate square wire torque angle, and the square wire does not have a vertical bending angle when the torque is formed, and the orthodontist can adjust the angle according to the patient's time. The angle of inclination of the teeth increases or decreases the torque of the arch wire during follow-up visits, so that the orthodontist will not deviate when controlling the torque of the patient's teeth. Due to the high accuracy of the torque of the square wire, it can be avoided when the patient's teeth are corrected. Too much damage to the teeth due to excessive torque or insufficient torque has no corrective effect on the teeth, which reduces the possibility of pain for the patient and shortens the course of correction, improves patient satisfaction, and improves the doctor's work efficiency and treatment effect.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a high-precision square wire torque forming device. Background technique [0002] At present, in the field of orthodontics, patients have higher and higher requirements for the beauty of teeth. The ultimate goal of orthodontic treatment is to make the dentition achieve functional, beautiful and stable effects, while good and personalized control of tooth torque It is one of the key factors to achieve functional, beautiful and stable orthodontic treatment goals. Good torque control can make the dentition form a smooth and soothing curve, which is beneficial to the appearance, and at the same time can make the teeth obtain normal overbite, overlay and occlusal relationship , and is conducive to the stability of the orthodontic result, therefore, the torque control of each tooth is an extremely important link in the orthodontic process. Orthodontists hope that t...

Problems solved by technology

[0005] 3. When torque pliers are used to twist the square wire, there is a problem of springback of the square wire. At present, there are two main materials of the square wire used for torque clinically, one is nickel-titanium square wire, and the other is stainless steel square wire

Among them, the nickel-titanium square wire has high elasticity. When the doctor uses the torque pliers to twist the nickel-titanium square wire, the ideal torque angle cannot be formed at one time, because the elastic square wire will rebound after being rotated. According to my own experience, I repeatedly twisted the nickel-titanium square wire until the ideal torque was achieved. In addition, the elasticity of different batches of nickel-titanium square wires from different manufacturers is different, and clinicians cannot accurately judge the springback of the square wire. It is to rely on one's own experience to twist the square wire, and then refer to the torque measurement chart to roughly estimate the torque angle of the formed arch wire, which will cause a large deviation in the torque of the square wire, and it is impossible to obtain an accurate square wire. The torque of the wire will cause a large deviation in the torque correction of the patient's teeth, and the actual clinical application effect is poor;

[0006] 4. Clinically, when torqueing some special teeth, especially some impacted teeth that have been pulled out to the palatal side of the dentition, long-term torque control is often required, and the torque angle needs to be increased slowly. Large, the torque angle of the arch wire must be adjusted according to the movement of the teeth. The amount of torque added each time is different. Only by realizing the precise control of the torque of the square wire can the teeth move physiologically under the optimum force. Using ordinary torque clamps and measuring charts cannot achieve accurate adjustment every time, nor can it accurately measure the existing torque angle on the current square wire;

[0007] 5. When the doctor uses torque pliers to perform torque bending on the square wire, the square wire is not fixed in a fixed way, and can only be held by the doctor or clamped by the torque pliers. At the same time, the doctor also needs to align the square wire with the square wire The angle chart is reversed. In order to achieve accurate bending, this requires the doctor's eyes, two torque pliers held in both hands, the square wire and the zero point of the torque measurement chart to be on the same horizontal line. If it is unstable, there will be shaking, which makes it difficult for the doctor to twist and bend the square wire precisely, which is extremely inconvenient to use;

[0008] 6. When the doctor uses torque pliers to perform torque bending on the square wire, due to lack of accurate measurement, sometimes the torque of the square wire is too large to be placed in the bracket, and it is necessary to take out the square wire and readjust the torque angle: or square If the wire torque is too small, effective torque movement cannot be achieved, which will prolong the treatment time of the patient
