The bone type II caused by mandible retraction in the bone type II classification is the most common in Asians, and the existing removable or fixed appliance can activate the perioral muscle function, promote the growth of mandible, reestablish the balance of new function and form and realize the purposes of guiding, coordinating growth and preventing and treating malocclusion deformity by changing the mandible position and occlusion position of a patient in the early stage of growth peak or in the peak period of growth peak.

In the history development process of the functional appliance, the appearance of the removable or fixed functional appliance pair further enhances the functional appliance for patients at the early stage, the peak stage and even the later stage of the peak period of growth and development. In recent years, the bracket-free invisible orthodontic technology uses the transparent tooth socket for orthodontic treatment, and overcomes the defects of traditional fixed orthodontic treatment in the aspects of attractiveness and comfort. However, the existing bracket-free invisible correction technology can realize a mandibular leading device, and can realize the full-Japanese mandibular leading to a certain extent, but has the following defects: 1. the existing invisible leading correction device needs patients to cooperate with active mandibular protrusion occlusion, and patients with mandibular leading function correction are basically teenagers, so that the subjective consciousness of the patients in the group is weak, the compliance is poor, the patients often do not cooperate with mandibular protrusion occlusion, and the correction effect is seriously influenced; 2. the front lower jaw has low efficiency when the appliance plays a role in sleeping, and the upper jaw and the lower jaw can be separated from occlusion due to the fact that a patient rises the relaxation of the jaw muscle group, particularly for a patient with mouth breathing, so that jaw orthopedics cannot be realized even if the appliance is worn at night in the precious time of exuberant secretion of growth hormone; 3. the upper dentition and the lower dentition are occluded in a separated manner by the bite block type appliance, discomfort caused by occlusion and chewing of a patient is increased, and the back teeth are separated for a long time, so that the situation that the back teeth are opened and closed after the appliance is finished can occur, a treatment scheme needs to be restarted at that time, and the treatment course of the patient is prolonged. These deficiencies limit the effectiveness and clinical applicability of existing invisible appliances.

In the bracket-free invisible orthodontic technology, the condition that maxillary posterior teeth need strong anchorage is many, for example, the bracket-free invisible orthodontic technology is commonly used for patients who need to design mild bone disorder with molar far and middle in the Anshi class II cases, or patients who need mild and moderate bone disorder with maxillary single-jaw extraction due to complete far and middle relationship of bilateral molar. The existing method for enhancing the maxillary posterior anchorage is II-type traction or implant anchorage for assisting in enhancing the maxillary posterior anchorage, however, the two methods for enhancing the maxillary posterior anchorage have defects: 1. class II traction is a tensile stress applied to the mouthpiece, side effects of which may lead to lingual inclination, elongation of the upper anterior teeth, mesial inclination of the lower molar teeth, and the like; 2. the implanted anchorage is invasive treatment, has certain traumatism, has relatively poor patient acceptance, and often leads to loosening and falling of the implanted anchorage due to the surrounding inflammation of the implanted anchorage caused by the difference of bone conditions or poor oral hygiene of patients, so that the long-term and effective anchorage cannot be provided.
