Forward traction and molar distalization combined type orthodontic device

Abstract

The invention discloses a forward traction and molar distalization combined type orthodontic device, which is characterized by comprising an upper moon-shaped plate, a lower moon-shaped plate, a sideedge supporting rod, an adjusting gear rod, a connecting sleeve, an adjusting gear button, a molar push rod, a forward traction push rod, a hoop ring and a bracket. According to the device, two correction processes of forward traction and molar distalization are combined, so that on one hand, the whole correction period is shortened, the cost is saved, and a patient is helped to get rid of the discomfort and inconvenience caused by the correction device as soon as possible; and on the other hand, the two processes can be combined for correction, and parameters such as direction and strength ofthe other process can be adjusted at any time according to the correction condition of one process, so that the correction effects of the two processes at last can be well connected.

Description

technical field [0001] The invention belongs to the field of oral orthodontic correction, and in particular relates to an orthodontic device combining front traction and molar remote movement. Background technique [0002] In clinical orthodontics, underdevelopment of the maxilla with moderate to severe crowding is a common type of malocclusion in adolescents at the peak of development; for such patients, the conventional treatment method is to use the maxillary anterior traction device to perform forward traction first, and stimulate the maxillary sagittal To adjust the sagittal relationship between the upper and lower jaws; after the front traction is over, use the pendulum push back molar to push back the molars, and move the first molars away to provide space for maxillary crowding . [0003] At present, clinically, due to the mutual interference of the two orthodontic devices, it is generally treated by a separate orthodontic method, that is, anterior traction correcti...

Problems solved by technology

[0003] At present, clinically, due to the mutual interference of the two orthodontic devices, it is generally treated by a separate orthodontic method, that is, anterior traction correction is performed first, and after the sagittal relationship between the upper and lower jaws is adjusted, the molars are pushed away and corrected; The separation of the two methods has the following defects: 1. Prolonging the orthodontic correction cycle, increasing the treatment cost of the patient and prolonging the period of discomfort caused by wearing the correction device; 2. The two parts of correction are performed separately using the front traction device and the molar distance pushing device Correction, the two processes are carried out separately, and the final correction effect of the two processes is also presented separately, which may cause the correction effect of the last two processes to be unable to be fully connected, and the correction process effect of the front traction cannot be combined with the correction process effect of the front traction to timely correct the molars. make adjustments and vice versa
