Stress testing apparatus and lingual orthodontic force measuring apparatus

Abstract

The invention discloses a stress testing apparatus and a lingual orthodontic force measuring apparatus. The stress testing apparatus comprises: a stress induction module having a plurality of resistor modules; a resistance testing module connected with the stress induction module, and used for acquiring the electrical signals of the plurality of resistor modules and measuring the resistance of each of the resistor modules; and a stress determination module connected with the resistance testing modules and used for determining corresponding stress according to the resistance. The lingual orthodontic force measuring apparatus comprises a lingual orthodontic bracket, an orthodontic arch wire and the stress testing apparatus, wherein the lingual orthodontic bracket is bonded to the lingual side of teeth and is fixed to the orthodontic arch wire, and the stress induction module of the stress testing apparatus is bonded to the labial side of the teeth. The stress testing apparatus and the lingual orthodontic force measuring apparatus realize the real-time accurate monitoring of the orthodontic force of a lingual side appliance, and provides a reliable basis for the improvement of the scheme of tooth treatment, the selection of the orthodontic arch wire with excellent performances and the improvement of the efficiency of a lingual orthodontic technique.

Description

technical field [0001] The invention relates to the field of orthodontics, in particular to a stress testing device and a lingual orthodontic force measuring device. Background technique [0002] As adult orthodontic patients have higher and higher aesthetic requirements for aligners, invisible orthodontics have attracted more and more attention from orthodontists. For this reason, several invisible orthodontic techniques have appeared, such as ceramic brackets, Invisalign appliances, lingual appliances, etc., but only the lingual appliance is truly invisible and can treat various malocclusions. appliance. Lingual orthodontics began in the 1970s and became popular in the 1980s, but was soon abandoned by most clinicians due to its complicated operation and difficulty in accurately controlling tooth movement. In the past ten years, the advocates and pioneers of lingual orthodontic technology have made lingual orthodontic technology a mature and efficient fixed orthodontic te...

AI Technical Summary

Problems solved by technology

[0003] However, for lingual orthodontic technology, the accuracy of the bonding of the lingual appliance, the performance of the orthodontic arch wire, the movement of the orthodontic teeth, and the magnitude of the orthodontic force are all factors that directly and always affect the orthodontic effect. At present, orthodontists can only use their clinical practice experience to perform lingual correction for patients, and there is no professional device for measuring the correction force of lingual appliances. Therefore, based on this situation, it is necessary to develop Develop a device that can accurately monitor the correction force of lingual appliance
