Description

Invisible correction device for bidirectional jaw regulation and control Technical Field The embodiment of the invention relates to the technical field of orthodontics, in particular to a bidirectional jawbone regulating invisible correction device. Background The Anshi III malocclusion is a clinically frequently occurring oral disease, usually manifested as retromaxillary, mandibular anterior, anterior or total dentition, often accompanied by lateral and sagittal defects of the maxilla. Such patients have typical concave side features including anterior genitalia, insufficient development of face, blunting of nose and lip corners, and increased height below, and these morphological abnormalities affect not only the oral and jaw functions of the patient such as chewing and pronunciation, but also the appearance and mental health of the appearance, and therefore, great importance should be attached to their correction. The trans Twin-Block appliance guides mandibular retraction through the inclined planes of the upper and lower guide plates. When the patient bites, the patient actively places the lower jaw at the inclined plane position, so that the functional adaptive response of masticatory muscles, teeth and periodontal tissues is stimulated, the muscular balance of the oral and jaw system is coordinated, and the jaw relation is gradually corrected. The inclined plane is designed to be smooth, the mandible is allowed to do lateral movement to a certain extent, the child patient can wear the device all day long and maintain normal functions such as speech and food, the influence on the oral function is small, and the correction efficiency is improved. However, the appliance is mainly suitable for functional class III malocclusions, which have limited effect on patients with bone class III with mild to moderate maxillary hypoplasias. Meanwhile, the patients often accompany dental arch stenosis or functional deviation, the requirement for arch expansion is remarkable, and the forward traction and arch expansion and the reverse Twin-Block are usually independent correction systems and are difficult to implement synchronously. In addition, the dentition alignment still needs to be carried out in the later stage of the correction, and the overall treatment course is longer. It is difficult to achieve multi-dimensional control of the jawbone, muscles, dental arches and dentition with either a single functional appliance or a hidden appliance, so it is necessary to integrate and modify the functions of both to construct a more efficient, systematic appliance. The existing scheme is double-stage correction, namely functional correction device, fixing correction device and invisible correction. One stage of functional correction is to guide the mandibular position, promote the development of upper jaw or coordinate the jaw relation by means of functional correction devices (such as trans Twin-block, anterior traction, etc.). The appliance is generally composed of a resin base support and a metal arch wire, wherein the resin base support covers part of dental arch and mucous membrane tissues to provide a main body structure and a retention support, and the metal arch wire is bent into functional parts such as a clamping ring, a lip arch and an induction wire to respectively play roles of retention, conduction of correction force or guiding tooth movement. And in the second stage of fixing/invisible correction stage, after the jaw relation is basically improved, a fixed correction device (such as a straight wire arch correction device) or an invisible correction device is used for carrying out dentition alignment, dental axis adjustment and fine positioning of the occlusion relation, and finally, a stable and well-functioning occlusion relation is established. Aiming at the existing scheme, the problems that the function of a single appliance is limited and synchronous control of jawbone, muscle, dentition and teeth cannot be realized are found. The dual-stage correction course is long and has low efficiency, and the curative effect is difficult to accurately connect and overlap. The functional appliance has large volume and obvious foreign body sensation, long-term influences on oral cavity functions, cleanness and beauty, and obviously reduces compliance of patients. Accordingly, there is a need to improve one or more problems in the related art as described above. It is noted that this section is intended to provide a background or context for the technical solutions of the invention set forth in the claims. The description herein is not admitted to be prior art by inclusion in this section. Disclosure of Invention The present invention is directed to a two-way jawbone-controlled concealed appliance that, at least in part, solves one or more of the above-mentioned problems due to the limitations and disadvantages of the related art. The invention provides a bidirectional jawbone regulation invisible correction dev
