Problems solved by technology

[0003] The purpose of the present invention is to provide a buccal multi-curved spring appliance and a buccal multi-curved spring mold. The appliance can solve the problem of adopting a pad plus lingual double-curved spring appliance. It is used in the period of deciduous teeth, and it is easy to cause deciduous dentition. The labial direction of the crown is tilted, and the crown that inherits the permanent teeth is more likely to develop in the palatal (lingual) direction, which can aggravate the crossbite of the permanent teeth and even lead to the failure of orthodontic treatment; when used in the replacement period, it can cause the crown of the upper anterior teeth to tilt labially, and the permanent Absorption of the root of the tooth can easily cause premature loss of the permanent teeth; the fixed inclined guide plate movable appliance for the lower anterior teeth may cause the elongation of the posterior teeth after wearing for a long time, the upper anterior teeth are labially inclined, and the lower anterior teeth are inclined to the tongue and open  and other deformities and the use of FR-III functional appliances, there are complex manufacturing, the lack of elasticity of its force, 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

specific Embodiment approach 1

[0008] Specific embodiment 1: This embodiment is described in conjunction with Fig. 1 to Fig. 5. The buccal multi-curved spring appliance of this embodiment is composed of an integral upper jaw rest 1, a mandibular rest 2 and two buccal multi-curved springs 5; Two buccal multi-curved springs 5 ​​are respectively arranged on the left side and the right side between the integral upper jaw rest 1 and the lower jaw rest 2, each of the buccal multi-curved springs 5 ​​is made of a stainless steel wire which is bent upwards sequentially. Maxillary curvature 16, forward curved mesial horizontal curvature 17, downward curved mesial curvature 18, upward curved longitudinal curvature 19, downward curved longitudinal curvature 20, upward curved distal curvature 21, backward curved The distal horizontal curve 22 and the downwardly curved mandibular curve 23 are composed; the upwardly curved maxillary curve 16 is perpendicular to the forwardly curved mesial horizontal curve 17, and the downw...

specific Embodiment approach 2

[0010] Specific embodiment two: this embodiment is described in conjunction with Fig. 1, the difference between this embodiment and specific embodiment one is: the spring wire diameter Φ of the buccal side multi-curved spring 5 of this embodiment is 0.9mm, so set, can satisfy The design requirements of the buccal multi-curved appliance achieve the best therapeutic purpose.

specific Embodiment approach 3

[0011]Specific embodiment three: This embodiment is described in conjunction with Fig. 6 and Fig. 7. The difference between this embodiment and specific embodiment one is: the upwardly curved maxillary curve 16 and the downwardly curved mandibular curve 23 of this embodiment both have The second coil 25, the inner diameter D1 of the first coil 24 and the inner diameter D2 of the second coil 25 are equal to 1.0-3.0 mm. This embodiment is used in conjunction with the specific embodiment 1 to increase the elastic force of the buccal multi-curved spring 5 to meet the design requirements.

Abstract

An appliance is presented. In said inventive appliance, the free end of the upward bend upper jaw of the side cheek with much crooked spring is buried within the upper jaw support, the free end of downward bend lower jaw is buried within the lower jaw support; in another appliance, the free end of the upward bend upper jaw of the side cheek with much crooked spring is buried within splitting upper jaw support, the free end of downward bend lower jaw is buried within the lower jaw support; 12 guide pins are installed within the placenta of side cheek with much crooked spring positioner.

Description

technical field [0001] The invention relates to a dental appliance and a mold. Background technique [0002] Angle's class III malocclusion, the molars are in the mesial relationship, and the anterior teeth are on the edge or under cover. Such malocclusions often lead to abnormal craniofacial bone development and affect the appearance, so they should be corrected as soon as possible. Orthodontics can use the lingual double-curved spring appliance with pads and lingual double-curved springs to push the maxillary incisors and move them to the labial direction to achieve the purpose of rectification. If it is used in the deciduous period, it is easy to cause the crown of the deciduous teeth If the labial direction is inclined, the crowns inherited from the permanent teeth are more likely to develop in the palatal (lingual) direction, which can aggravate the crossbite of the permanent teeth and even lead to the failure of orthodontic treatment; Tooth root resorption can easily...
