Description

TECHNICAL FIELD

[0001] The utility model relates to dental orthodontic appliance technical field, concretely relates to a single jaw type appliance. BACKGROUND

[0002] The reaction force generated by molar distal movement in the bracket-free invisible orthodontic treatment can cause the anchorage tooth to shift, resulting in low treatment success rate of molar distal movement cases, and the effect of implant anchorage and interarch traction in assisting the control of anterior teeth labial inclination is not good. Severe labial inclination of anterior teeth can increase the risk of periodontal disease, and the molar distal movement and anterior teeth retraction cannot reach the expected treatment target, resulting in long treatment time. The sagittal and vertical directions of the anterior teeth of the molar distal movement case need additional anchorage force to assist in control.

[0003] In the existing invisible orthodontic technology, the methods for preventing the labial inclination of anterior teeth in molar distal movement cases are: 1. Elastic traction between implant anchorage and invisible aligner is used for control, and the disadvantage is that implant anchorage may cause gum inflammation, resulting in loosening and affecting the control effect of anchorage; 2. Interarch traction is used to assist in control, and the disadvantage is that it will cause the loss of anchorage of the labial inclination of the opposite anterior teeth, and in the case of distal movement of the opposite molars, such enhanced anchorage method cannot be used.

[0004] In view of the above problems, the applicant has applied for a patent with the patent number ZL202323560053.2 and the patent name of a kind of appliance, and the authorized announcement number of China utility model patent is CN 221490250 U, but the patent can only correct the upper and lower anterior teeth at the same time, and cannot be used for patients who only need to control the anchorage of the upper anterior teeth or the lower anterior teeth.
