Description

Technical Field

[0001] The present application relates to the technical field of clinical oral orthodontics, and in particular to a detachable extraoral arch muscle activator. Background Art

[0002] Dentomaxillary deformity is one of the three major oral diseases in my country (caries, periodontal disease and dentomaxillary deformity), such as malocclusion of teeth, protrusion of upper teeth, chin tilt and crooked mouth. With the continuous deepening of clinical research, the concept of modern dental deformity is far from referring only to the misalignment and misalignment of teeth, but also to a variety of deformities caused by the imbalance between teeth and craniofacial relations; it not only affects the growth and development of the patient's occlusion, jaw and face, facial beauty and oral function, but also greatly hinders the physical and mental health of patients, especially children. It becomes more serious with age, especially those with congenital genetic factors. In recent years, mechanical appliances such as removable appliances and fixed appliances have been used in China to correct malocclusion and misalignment of teeth, but the correction effect of jaw deformities such as maxillary protrusion (buck teeth), crossbite (underbite) and other bone deformities is poor, and it must be combined with surgical operations to be completely corrected. The operation is difficult and difficult for general patients to accept.

[0003] However, the common extraoral arch muscle activator is an integrated one. After the patient wears it, the extraoral arch used to pull the upper front teeth backward and contract inward needs to be fixed by a connecting device externally connected to the head. Over a long period of time, the teeth are heavily burdened and the upper front teeth may tilt inward. It is also inconvenient to take off the band, and the patient's cooperation is low during wearing. Therefore, those skilled in the art provide a detachable extraoral arch muscle activator to solve the problems raised in the above background technology. Utility Model Content
