TECHNICAL FIELD
[0001] The utility model relates to a device for orthodontic traction of fractured anterior teeth. BACKGROUND
[0002] External injury, root surface caries, wedge-shaped defect and other lesions of teeth can all lead to root / crown-root joint fracture, which not only affects the appearance, but also seriously affects the function of teeth. Among all these reasons, tooth injury is the most common, especially the injury of maxillary anterior teeth. At present, there are several methods for orthodontic traction before repair of fractured anterior teeth.
[0003] Removable traction device: using removable device for traction, although the operation is relatively flexible, but it is difficult to accurately control the movement of teeth. In addition, this method requires high compliance of patients, such as patients taking off the device at will, which may affect the treatment effect; at the same time, it also requires high integrity of the dentition and retention force of the appliance, and the comfort of the patient is relatively poor.
[0004] 2. Direct traction of the affected tooth by bending the arch wire of the traditional appliance: this method cannot accurately adjust the traction direction, and needs to bend the arch wire several times to adapt to the traction of the residual root, which takes a long time in clinical operation;
[0005] 3. Neodymium iron boron permanent magnet for magnetic traction, that is, the affected tooth is attracted by the magnetic force between the small magnetic blocks on the appliance and the magnetic blocks adhered to the surface of the affected tooth. This method does not need to replace the rubber chain regularly to apply force to the affected tooth, and the patient can take off and wear it by himself, which is easy to clean. However, the traction direction is not easy to control accurately, and the magnetic orthodontic force will show as a rapidly increasing continuous orthodontic force as the magnetic blocks approach each other, at the same time, the excessive volume of the magnetic blocks occupies the limited space of the affected tooth movement, and the permanent magnet may be corroded by saliva. In summary, each method has its own unique advantages and limitations. SUMMARY
[0006] The technical problem to be solved by the utility model is to provide a device for orthodontic traction of fractured anterior teeth.

[0011] The positive effects of the utility model are as follows:
[0012] The utility model discloses a movable module device, realize ingenious structure design, the near and far of the direction of the lip and palate of the traction is adjusted at any time conveniently, wherein, limiting adjusting buckle has cross adjusting groove, and the adjusting shaft is adjusted through the tool conveniently, thereby adjusting the compression degree of compression spring, and then the traction degree is flexibly controlled, while protecting teeth and surrounding tissues, the traction demand of different patients is more accurately satisfied.
[0013] The application effectively avoids the palate inclination of the tooth being pulled, the tooth is pulled to the position and basically obtains the overall movement along the tooth long axis, and the traction direction is adjusted in the patient's mouth at any time, according to the tooth displacement of the patient, a set of device can adapt to various symptoms, and it is guaranteed that the dental crown obtains enough anterior tooth coverage when the next repair treatment is carried out, and the tooth root can better bear the occlusal force.

[0018] As shown in the attached Figures 1-4 The utility model discloses a stainless steel wire 2, it is characterized in that still includes ligature ring 1, tongue side buckle 3, traction rubber chain 4 and movable module device, the stainless steel wire 2 is provided with rubber band fixed block 10 and two or more than ligature ring 1, the traction rubber chain 4 both ends are fixed on tongue side buckle 3 and rubber band fixed block 10 respectively, the rubber band fixed block 10 is provided with limiting sliding slot 11,
[0019] The movable module device comprises a fixing base 5, an adjusting shaft 7, a compression spring 6 and a limiting adjusting buckle 8, one side of the limiting adjusting buckle 8 is fixedly connected with one end of the adjusting shaft 7, the other end of the adjusting shaft 7 is provided with a thread, the threaded end of the adjusting shaft 7 is inserted into a threaded slot of the fixing base 5, the compression spring 6 is arranged between the fixing base 5 and the limiting adjusting buckle 8, and the rear end of the fixing base 5 is provided with a sliding block.
[0020] A cross adjusting groove 9 is arranged on the limiting adjusting buckle 8.
[0021] The treatment process of the utility model is as follows:
[0022] (1) The tooth root of the affected tooth is temporarily restored by a post core crown, a lingual buckle is adhered to the neck of the temporary crown, before adhesion, the surface of the crown is lightly ground by using a sandstone needle to make it rough, so that the adhesion of the adhesive is enhanced.
[0023] (2) The brackets are adhered to the labial surfaces of the two adjacent teeth of the affected tooth, and the brackets are located on the same horizontal line as far as possible, during the adhesion process, the non-fitting part between the brackets and the tooth surface is compensated by the thickness of the adhesive, and external force is avoided to press, so that the stable adhesion of the bracket is ensured.

According to the traction direction of the affected tooth, the fixed module can be moved left and right, and the elastic line is fixed in different positions of the built-in spring of the module to change the lip and palate traction direction of the affected tooth. At the same time, attention should be paid to the jaw adjustment, so as to prevent early contact and ensure the stability of the occlusal relationship.
[0030] Temporary crown treatment: for patients with aesthetic requirements, the part of the temporary crown that is elongated at the cutting edge can be ground, so as to meet the aesthetic requirements. However, for most patients, the height of the cutting edge should be lowered as far as possible, so as to accurately judge the actual elongation distance of the tooth root.
