Description

Technical Field

[0001] The utility model mainly relates to the technical field of orthodontic instruments, in particular to an upright inclined teeth grinding device. Background Art

[0002] The most common cause of upright tilted molars is the imbalance of tooth and bone mass in the posterior segment, resulting in buccolingual or mesiodistal growth of the teeth.

[0003] At present, the tilt of the second molar can usually be corrected by wearing braces or orthodontic surgery. It is recommended to go to the hospital for examination and the doctor will choose the appropriate method to correct it according to the specific tilt of the teeth. The teeth can be pulled by implanting archwires to realign the patient's uneven teeth. The specific operation method is as follows: stick the bracket on the tooth, insert the archwire into the groove of the bracket, and then tie the ligature between the upper and lower wings of the bracket to fix the archwire on the bracket. Use the rebound rigidity of the archwire to gradually achieve tooth correction. However, the bending size of the archwire stretched by this method is difficult to control, and the force is inconsistent. It will make the patient uncomfortable during the operation. The patient cannot see the correction of his own teeth, so he needs to see a doctor frequently. Therefore, an upright tilted molar device that can automatically and slowly stretch is needed to solve the above problems. Utility Model Content

[0004] The technical solution of the utility model aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technology. It mainly provides an upright inclined molar device to solve the problem that the bending size of the stretching arch wire of the traditional upright inclined molar correction technology proposed in the above background technology is difficult to control and the force is inconsistent, which makes the patient uncomfortable during operation and the patient cannot see the status of his or her own teeth correction, so he needs to seek medical examination frequently.

[0005] The utility model adopts the following technical solution to solve the above technical problems: an upright inclined molar device, comprising a bracket, the back of the bracket is connected and fixed to the tooth surface by an adhesive, the middle and upper end of the front of the bracket is connected and fixed to one end of a second docking tube, the other end of the outer ring of the second docking tube is sleeved with the inner ring of the first docking tube, the inner ring of the second docking tube is provided with a thread, the thread provided on the inner ring of the second docking tube is connected with a screw thread, the end of the first docking tube away from the bracket is fixedly connected to an outer cover shell, and the outer ring of the second docking tube is sleeved with the inner ring of a torsion elastic member;

[0006] The lower end of the stretching block is provided with an archwire hole, a holding block is arranged in the archwire hole, a holding threaded hole is provided at the bottom of the stretching block, the holding threaded hole is threadedly connected with a fixing bolt, and the head of the fixing bolt passes through the holding threaded hole and is rotatably connected with one side of the holding block.

[0007] Preferably, the outer ring section of the second docking sleeve is hexagonal, and the inner ring section of the first docking sleeve is hexagonal.

[0008] Preferably, the outer cover shell is a U-shaped structure, the outer ring of the torsion elastic member is fitted with the inner wall of the outer cover shell, the middle position of the lower end of the torsion elastic member is clamped with the clamping block, and the two ends of the torsion elastic member are connected and fixed to one side of the stretching block.

[0009] Preferably, the cross-section of the holding block is arc-shaped, the inner ring of the holding block is in contact with the outer ring of the arch wire, and the outer ring of the holding block is rotatably connected to the head of the fixing bolt through a bearing compared with the prior art.

[0010] The beneficial effects of the utility model are as follows: the archwire is passed through the archwire hole opened by the stretching block and the fixing bolt is turned, the fixing bolt drives the holding block to fix the archwire, and then the clamping block is removed so that the torsion elastic member drives the archwire to be continuously stretched, thereby driving the displacement of the teeth that need to be corrected to be corrected. The traditional method is to stretch and fix the archwire by a doctor at one time, while this method is a slow stretching process, and the stretching condition of the torsion elastic member can be observed, so as to judge whether medical treatment is needed for adjustment, which is more suitable for patients.

[0022] Please refer to the attached Figure 1 and attached Figure 2 The outer cover shell 1 is a U-shaped structure, and the outer ring of the torsion elastic member 3 is fitted with the inner wall of the outer cover shell 1. The fitting can make the torsion elastic member 3 more stable when expanding or contracting. The middle position of the lower end of the torsion elastic member 3 is clamped with the U-shaped clamping block 4. By removing the clamping block 4, the two ends of the torsion elastic member 3 can be expanded, thereby facilitating the contraction of the arch wire. The two ends of the torsion elastic member 3 are connected and fixed to one side of the stretching block 5.
