Buccal side multiple curve spring correction device and buccal side multiple curve spring mould

Abstract

The buccal multi-curved spring appliance and the buccal multi-curved spring device are aimed at the  pad plus lingual double-curved spring appliance. When used in the deciduous period, it is easy to cause the crown of the deciduous tooth to tilt labially and when used in the replacement dentition, it may cause The labial tilt of the crowns of the maxillary anterior teeth; the movable appliance with a fixed slant guide plate for the lower anterior teeth may easily cause open- deformity and the FR-III functional appliance may easily cause compensatory lingual tilting of the lower anterior teeth. In the appliance of the present invention, the free end of the upwardly curved maxillary curve (16) of the buccal multi-curved spring (5) is embedded in the integral upper jaw support (1), and the free end of the downwardly curved mandibular curve (23) is embedded into the mandibular rest (2); another appliance, the free end of the upwardly curved maxillary curve (16) of the buccal multi-curved spring (5) is embedded in the split maxillary rest (3), and the downwardly curved mandibular The free end of song (23) is embedded in the mandibular support (2); Twelve guide pins (41) are housed in the placenta (27) of buccal side multi-curved spring tire. The appliance is simple to manufacture, easy to try on, short treatment period, and the multi-curved spring mold on the buccal side has the advantages of simple structure.

Description

Technical field [0001] The invention relates to a dental appliance and a mould. Background technique [0002] Class III fault , The molars are in a mesial relationship, and the anterior teeth are on the opposite edge or reversely covered. Such mistakes It often leads to abnormal craniofacial skeletal development, which affects the appearance and appearance, and should be corrected as soon as possible. Correction can be used Pad plus lingual hyperbolic spring appliance, use the lingual hyperbolic spring to push the maxillary incisor to move it to the lip to correct the reverse For the purpose of using it in the deciduous tooth period, it is easy to cause the crown of the deciduous tooth to tilt toward the lip, and the crown of the permanent tooth is more likely to develop in the palatal (lingual) direction, which can aggravate the anti-reflection of the permanent tooth. , And even lead to failure of the correction; if used in the replacement period, it can cause the crown of ...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a buccal multi-curved spring appliance and a buccal multi-curved spring mold, which can solve the problem of adopting Pad plus lingual double-curved spring appliance, used in the deciduous period, can easily cause the crown of the deciduous tooth to tilt labially, and the crown that inherits the permanent tooth is more likely to develop in the palatal (lingual) direction, which can aggravate the permanent tooth crossbite , and even lead to the failure of orthodontic treatment; when used in the replacement period, it can cause the labial tilt of the crown of the upper anterior teeth, and the root of the permanent teeth will absorb, which may easily cause the problem of premature loss of the permanent teeth; the fixed inclined guide plate movable appliance for the lower anterior teeth, wear time Elongation can easily lead to elongation of the posterior teeth, labial inclination of the upper anterior teeth, and lingual inclination and opening of the lower anterior teeth. Deformity problems and the use of FR-III functional appliances, there are complex production, the force lacks elasticity, and it is easy to cause the labial tilt of the upper anterior teeth, and the compensatory lingual tilt of the lower anterior teeth and other adverse consequences
