Background technique

In recent years, with the improvement of the quality of life, people pay more and more attention to the beauty of teeth, and orthodontic technology is also widely favored by people. However, there are still deficiencies in the current orthodontic technology. For example, in the process of moving and correcting the teeth, it is impossible to accurately judge the magnitude of the force and moment on the teeth. If the traction force is too small, the expected effect cannot be achieved. Period, excessive traction may cause discomfort to the patient, and excessive traction may lead to alveolar bone stress concentration and damage to the original oral tissue, these are not what we want to see. At present, the direction of tooth movement, orthodontic force, and torque are mainly determined by the experience of doctors. Orthodontists can replace the arch wire at an appropriate time based on experience to help patients achieve the desired orthodontic effect. Therefore, accurate measurement of the orthodontic force and the magnitude of the orthodontic torque on the teeth during the orthodontic process has become a key point to break through the orthodontic barrier and promote orthodontic technology in a wider range. For this reason, various colleges and universities and research departments have also carried out experimental research one after another. The present invention proposes a three-dimensional orthodontic correction force measuring device.
