Background

Malocclusion refers to the abnormal arrangement of teeth, abnormal occlusion of upper and lower dental arches, and abnormal position of jaw bone in size and shape caused by congenital genetic factors or acquired environmental factors such as diseases, bad habits of oral cavity, and dysdontia. The anglerian class iii malocclusion is a clinically common malocclusion, which is characterized primarily by anterior retroocclusions (i.e., often called "ground-centered" occlusions) and a depression in the mid-face. At present, the method for correcting the class III angstrom malocclusion mainly comprises early functional correction, masking correction of the permanent dentition and orthodontic orthognathic combined correction after growth and development are finished. The early correction mainly comprises various modes such as anterior traction, a Frank III functional corrector, a jaw pad type corrector and the like. However, the inventor of the present invention has found through research that these appliances are somewhat unsuitable for daytime use, somewhat inconvenient for controlling tooth movement when worn, somewhat unsatisfactory for aesthetic purposes in correction, or inadequate for functional consideration and control of malocclusion.
