Mandible guiding forward and fixed orthodontic combined correction device

Abstract

The invention discloses a mandible guiding forward and fixed orthodontic combined correction device, which comprises a maxillary correction device and a mandibular correction device, wherein the maxillary correction device comprises a first metal joint crown and a palate rod which are arranged on a first molar and a second premolar or a second primary molar, a first buccal tube (the formula is shown in the formula) and a pad are arranged on the first metal joint crown, an upper dentition main arch wire is arranged on the first buccal tube, (the formula is shown in the formula) and a power armis arranged on one side of the pad; the mandibular correction device comprises a second metal joint crown and a tongue arch which are arranged on the first molar and the second premolar or the primarymolar, a second buccal tube is arranged on the buccal side of the second metal joint crown, a lower dentition main arch wire is arranged on the second buccal tube, the second metal joint crown is provided with (the formula is shown in the formula) a blocking arm which matches with the power arm of the pad. According to the mandible guiding forward and fixed orthodontic combined correction device,the maxillary power arm and the mandibular blocking arm are matched to realize that the mandible is guided forwards, and the fixed correction is realized through the bracket, the upper dentition mainarch wire and the lower dentition main arch wire arranged on the tooth surface, so that the device has the advantages of strong support, convenient operation, good correction effect, sound patient experience and the like.

Description

technical field [0001] The invention belongs to the field of orthodontics, and in particular relates to a combined orthodontic device for guiding mandible forward and fixed orthodontics. Background technique [0002] Currently, for type II errors with growth and development potential The treatment of deformity patients still mainly adopts the traditional two-stage treatment, which includes stage I functional correction and stage II fixed orthodontic correction. Phase I functional correction is mainly to block or correct skeletal deformities and coordinate the relationship between the upper and lower jaws. Phase II fixed orthodontic correction is mainly to align and level the retracted dentition and adjust the occlusal relationship. Two-phase separate treatment not only takes a long course of treatment, but also affects patient compliance and treatment initiative. [0003] Type II error Deformed functional appliances include removable functional appliances and fixed fun...

AI Technical Summary

Problems solved by technology

Type II error The fixed-function appliances for deformity mainly include: 1. The rigid fixed-function appliance represented by Herbst, which guides the mandible forward through the casing structure, and the anchorage is concentrated on the posterior teeth, but Herbst has poor anchorage control and lateral 2. Elastic fixed-function appliances represented by JasperJumper and Forsus push the mandible forward through a spring structure, but they all have obvious lip inclination of mandibular incisors, 3. Fixed-function appliances represented by MARA (Mandibular Protrusion Repositioning Appliance) force the mandible to be in the position of protruding through the locking effect of the lateral structure on the upper and lower molars. The anchorage is only the upper and lower first molars, the sagittal and vertical anchorage control is insufficient, and it is still difficult to provide sufficient anchorage; and the front and rear teeth of the mandible cannot establish an occlusion, which affects the patient's eating, and excessive muscle strength is easy to make Deformed or damaged aligners

[0004] In addition, the existing The functional orthopedic technology for deformity, after the first-stage treatment, the anterior teeth are mostly in contact, and the posterior teeth are opened. In this state, it is difficult to maintain the leading mandibular position, and the curative effect is extremely unstable; in addition, the existing correction of class II malocclusion For functional appliances, there is a common problem that the lower anterior teeth are obviously tilted when leading the mandible, which in turn affects the mandibular leading space, resulting in insufficient mandibular leading.

At present, there is no appliance that combines functional orthopedic treatment and fixed orthodontic correction, and can effectively avoid labial inclination of the lower incisors.
