Anterior traction intraoral device and manufacturing method thereof

Abstract

The invention discloses a front traction mouth device and a manufacturing method thereof, comprising: a pair of retaining components, each retaining component includes a retaining crown, a traction hook and a connecting rod, and the retaining crown is used to wrap one side of the mouth For the first premolar, second premolar and first molar, the traction hook is set on the buccal side of the retaining crown, and the connecting rod is set on the lingual side of the retaining crown; the hyperbolic reed, one end of which is connected to the On the connecting rod, the other end is used to abut against the lingual side of the incisor in the mouth; the screw expander, the two ends of the screw expander are respectively connected to the connecting rod of a retention component. This solution is more conducive to the stability of wearing the device in the front traction mouth. During the front traction, it can expand the arch and solve the crowding of the anterior teeth in combination with clinical needs, and improve the efficiency of orthodontic treatment.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, and more particularly relates to a front traction intraoral device and a manufacturing method thereof. Background technique [0002] Class III skeletal deformity is a relatively common type of deformity in clinical practice. Because of its complex craniofacial morphology, it tends to aggravate the degree of deformity with growth and development. It is difficult to treat clinically, and early correction is usually required for such patients. Among many early orthodontic devices, the anterior traction device is considered to be an effective treatment method for patients with maxillary retrusion, and has a good prognosis; some studies believe that the combination of rapid arch expansion during anterior traction will loosen the suture zone. It can achieve better anterior traction effect, and at the same time reduce the adverse reactions that are easily caused by forward traction such as clockwis...

Problems solved by technology

Among many early orthodontic devices, the anterior traction device is considered to be an effective treatment method for patients with maxillary retrusion, and has a good prognosis; some studies believe that the combination of rapid arch expansion during anterior traction will loosen the suture zone. To achieve a better anterior traction effect, and at the same time reduce the adverse reactions that are likely to be caused by the front traction such as the clockwise rotation of the mandible, but in the prior art, most of the intraoral components of the anterior traction device cannot perform other treatments at the same time and have poor stability
