Embodiment Construction

[0012] The specific implementation will be described in detail below in conjunction with the accompanying drawings: Figure 1 ~ Figure 3 One embodiment of the invention is shown. In the figure, an orthopedic device that stimulates the leading of the mandible and inhibits the growth of the maxilla includes a part of the maxilla and a part of the mandible; wherein:

[0013] The upper jaw part has a left / right plastic occlusal pad 11, a screw opener 12, and two left / right palatal rods 13, one front and one rear, and the left / right plastic occlusal pad starts from the first upper jaw. The premolars or first deciduous molars extend to the last molar that has erupted in the oral cavity and wrap the crowns of the above teeth. The edge of the occlusal pad is 1-2mm away from the gingival margin, which is conducive to the health of the gums. The left / right plastic occlusal pad embeds the MBT bracket at the center of the buccal surface of the maxillary first premolar or first deciduous ...

Abstract

The invention relates to an orthopedic device stimulating lower mandibular advancement and inhibiting upper mandibular growth, comprising an upper mandibular portion and a lower mandibular portion. The upper mandibular portion has left and right plastic occlusal pads, a screw opener, and left and right jaw rods with one located behind the other. The screw opener is located at the midline of the upper mandibular jaw of a patient. The left and right plastic jaw rods have one end fixed to the screw opener and the other end integrated to the left and right plastic occlusal pads. The lower mandibular portion has left and right plastic occlusal pads connected via a lower mandibular lingual plastic base, a snap ring, and spherical adjacent hooks, the left and right occlusal pads of the lower mandibular portion cover occlusal surfaces of lower mandibular left and right first premolar teeth or first deciduous molars and are in a slant crossing relation 70 degrees upwardly and towards mesiocclusion with the left and right occlusal pads of the upper mandibular portion at the distal of the first premolar teeth or first deciduous molars. The orthopedic device has the advantages that the device is fixedly bonded to upper dentition through the upper mandibular portion, the lower mandibular portion is mechanically secured to lower dentition through the snap ring, adjacent hooks and the lengthened base, and this structural configuration has ideal orthopedic effect.

Description

technical field [0001] The invention relates to an orthodontic appliance, in particular to an orthopedic device for stimulating the leading of the lower jaw and inhibiting the growth of the upper jaw. Background technique [0002] Bone protrusion is one of the more common clinical malocclusions in orthodontics. In Chinese, it typically manifests as sagittal upward maxillary protrusion and mandibular regression with deep overbite and deep coverage of the anterior teeth, and horizontally upward maxillary protrusion. The width of the basal arch is underdeveloped. At present, the traditional orthopedic device used to treat bony protruding face deformity is a movable mandibular leading functional appliance, and its function depends on the patient's wearing, because only the continuous load stress change of the condyle is possible. It brings about a substantial increase in the length of the mandible and inhibition of the overgrowth of the maxilla, thereby improving the sagittal i...
