Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tooth correction, in particular to a special corrector for adjusting uneven tooth midlines. Background Art
[0002] Eccentric occlusion refers to the lateral imbalance of the upper and lower occlusions and the inconsistency of the dental midlines. It often causes bilateral facial asymmetry and occlusal disorder in patients, seriously affecting the patient's appearance, chewing, and pronunciation functions, and causing great physiological and psychological pressure on patients. The causes of eccentric occlusion are relatively complex, and there is still no unified understanding, but it can be preliminarily divided into two categories: congenital and acquired. Among congenital factors, due to embryonic development disorders, the three-dimensional development of the craniomaxillofacial bones on one side is insufficient, the bilateral development is unbalanced, and the jaw grows eccentrically, leading to the occurrence of eccentric occlusion. Among acquired factors, it can be caused by trauma, infection, benign hyperplasia, bone tumors, soft tissue tumor compression and other reasons. For patients in the growth and development period, orthopedic treatment can correct mild eccentric occlusion during development. However, the correction effect of corrective appliances in clinical practice is not good.
[0003] In the process of orthodontic treatment of incisors, wire brackets are often used. The wires and brackets are used to apply force to the teeth to gradually move them to the correct position. This type of product often needs to be used with rubber bands of different elasticity, which is cumbersome to use. Invisible braces are also used for tooth correction. Invisible braces are a transparent correction device that hardly affects the appearance of teeth and has a good correction effect. However, different braces need to be replaced at different stages, and the cost is relatively high.
[0004] Therefore, the present application proposes a special corrector for adjusting the misalignment of the dental midline to solve the above-mentioned problem. Utility Model Content

[0007] The adjustment mechanism includes two connecting sleeves, and the two connecting sleeves are respectively embedded in the adjustment groove and the adjacent side walls of the adjustment member. An internal threaded adjustment tube is fixedly connected to the inner side wall of the connecting sleeve, and an intermediate column is arranged between the two internal threaded adjustment tubes. The left and right ends of the intermediate column are fixedly connected with external threaded rods, and the ends of the two external threaded rods away from the intermediate column respectively penetrate the two internal threaded adjustment tubes and extend to the inside of the main brace and the adjustment member. The external threaded rod is threadedly connected to the internal threaded adjustment tube, and at least three adjustment holes are evenly opened on the intermediate column.
[0008] Preferably, both the front and rear sides of the internally threaded adjustment tube are provided with limiting tubes, and the outer side wall of the limiting tube is fixedly connected to the inner side wall of the connecting sleeve.
[0009] Preferably, two limiting columns are arranged between the two connecting sleeves, and the two limiting columns are respectively located at the front and rear sides of the middle column.
[0010] Preferably, both left and right ends of the middle column are fixedly connected to limit slide rods, and the ends of the two limit slide rods away from the limit column respectively pass through the left and right limit tubes and extend to the interior of the main braces and the adjustment member, and the limit slide rods are slidably connected to the limit tubes.
[0011] Compared with the related art, the special orthodontic appliance for adjusting the misalignment of the tooth centerline provided by the utility model has the following advantages:
[0012] Beneficial effects:
[0013] The utility model provides a special corrector for adjusting the misalignment of tooth midline. The device is connected to the teeth behind the front teeth through the main braces, and the external threaded rods on the left and right sides are driven to rotate by rotating the middle column. The position of the adjusting piece is adjusted by the cooperation of the external threaded rod and the internal threaded adjustment tube. The elastic limit hook cooperates with the front teeth, so that a certain force is applied to the front teeth under the action of the elastic limit hook, thereby correcting the misalignment of the front teeth midline. During the correction process, there is no need to frequently replace the device and other related accessories, so that the cost of the device is relatively low, and the device is more practical and convenient to meet the needs of patients.
