Description
Technical Field
The utility model relates to the field of oral cavities, in particular to a nance-bracket appliance with a leading mandibular function.
Background
In orthodontic treatment, orthodontic devices commonly used include nance arches, palate bars, plane guide plate aligners (abbreviated as flat guides), inclined guide plate aligners (abbreviated as inclined guides), and the like. They deal with different oral problems separately. The maxillary nance tray and the palate bar are clinically common devices for enhancing anchorage and preventing posterior tooth advancement; the plane guide plate corrector is mainly used for rapidly opening occlusion and improving deep jaw coverage; the inclined guide plate corrector can guide the occlusion forward extending position when the mandibular closure moves, and is beneficial to promoting the correction of Anshi class II error (dentition) deformity.
For teenagers with an malocclusion (malocclusion) caused by a functional factor or in a growth and development peak period, the occlusion relationship of the posterior teeth is always in an abnormal state and the facial form is always convex, and in order to achieve an ideal occlusion relationship and good facial form improvement of the posterior teeth, a scheme of extracting teeth and leading the lower jaw is usually adopted in orthodontic treatment. The tooth extraction is not only beneficial to improving abnormal occlusion relation of the posterior teeth, but also beneficial to aligning upper and lower dentitions, relieving functional factors such as interference, eliminating the cause of mandibular retroversion and creating space for mandibular leading. However, in the tooth alignment process, the possibility of loss of tooth extraction gap and correction failure caused by forward movement of the rear teeth exists, and generally, in order to prevent forward movement of the rear teeth, a user generally wears nance torr on the upper jaw, wears a functional appliance such as an upper jaw inclined guide plate, FRII or Twin-block to guide the lower jaw after the teeth are aligned, so that the facial form of a patient is improved to the greatest extent.
However, the clinical observation shows that the treatment time period is longer, the user needs to wear the maxillary nance support to prevent the front teeth from moving forward in the tooth alignment and leveling process, and wear the functional appliance such as the maxillary inclined guide plate, FRII or Twin-block to guide the mandible after the teeth are aligned and leveled. Currently, for wearing these functional appliances, the patient mostly reflects a perceived discomfort and, due to the poor compliance of teenagers' patients, few or even no relevant appliances of the leading mandible are worn. However, the optimal treatment time for improving the mandibular retraction for non-operative treatment is slightly elapsed, and the long-time alignment and leveling of the dentition and the poor self-coordination of the patient easily lead to the patient missing the golden age for correcting the mandibular retraction, so that the problem of mandibular retraction can be thoroughly improved only through operative treatment after the adult.
