AI Technical Summary
During orthodontic treatment, excessively rapid tooth movement or directional deviation can damage periodontal tissues, leading to loose teeth, shortened and thinned roots, and increased risk of tooth loss. Current technologies struggle to effectively monitor and provide early warnings for these issues.
A sealed liquid reservoir and a connecting rod are installed on the metal bracket. The connecting rod moves the sealed liquid reservoir. When the tooth moves beyond the threshold, a leakage switch is triggered, causing warning liquid to flow into the patient's mouth, thus providing an early warning.
Effective monitoring of tooth movement, timely warning of tooth movement deviations, improved stability of orthodontic treatment, and reduced periodontal tissue damage.

TECHNICAL FIELD
[0001] The present application relates to the technical field of malposed teeth correction, in particular to a periodontal tissue health monitoring and early warning device and method in orthodontic tooth movement. BACKGROUND
[0002] It is known that when using a metal dental brace to correct malposed teeth, the metal bracket is fixed on the surface of the tooth, and the arch wire passes through the metal bracket, and the size and direction of the force on the metal bracket are controlled by adjusting the shape and tension of the arch wire, and the malposed teeth are corrected by the force on the metal bracket. When correcting malposed teeth, as the teeth move, the arch wire moves in the metal bracket, and the speed of tooth movement during correction is too fast, which can cause damage to the periodontal tissue. The direction of the movement of the arch wire reflects the movement of the teeth, and the deviation of the direction of the movement of the arch wire indicates that the force for correcting the teeth is deviated. The deviation of the force for correcting the teeth not only fails to correct the malposed teeth back, but also causes the malposed teeth to shift more seriously, and the malposed teeth need to be corrected back in the later period. The back-and-forth movement of the teeth can cause the teeth to loosen, and the back-and-forth movement of the teeth can cause the roots to become shorter and thinner (root resorption), which reduces the stability of the teeth and increases the risk of premature loss. Therefore, we propose a periodontal tissue health monitoring and early warning device and method in malposed teeth movement. SUMMARY
