Embodiment 1

[0032] A partial occlusion functional orthodontist, comprising a maxillary part and a mandibular part, the maxillary part includes arrow clips 1 fixed on the molars on the left and right sides, single-wall clips 3 fixed on the bicuspids on the left and right sides, and connecting The occlusal pad 2 of the arrow card 1 and the single wall card 3, the mandibular part includes the interproximal hook 4 fixed on the incisors and canines, the arrow card 1 fixed on the canines on the left and right sides, and the connecting arrow card 1 and The occlusal pad 2 of the interproximal hook 4, the maxillary part and the mandibular part each include a guide slope 5, the guide slope 5 is located inside the bicuspid teeth, and the angle between the guide slope 5 and the occlusal surface is 40-60 degrees, and the direction of inclination is the same as that of the occlusal surface. The jaw deviates in the opposite direction.

Embodiment 2

[0034] A method of making a partial occlusion functional aligner:

[0035] a. Take the impressions of the upper and lower dentition respectively, and fill the plaster model;

[0036] b. Take the occlusal record: record the occlusal relationship when the upper and lower jaw midlines are aligned with a wax film in the patient's mouth, remove the wax film, put it on the model for verification, and use the facebow transfer technology to strictly follow the occlusal relationship recorded on the wax film. The plaster model is fixed on an adjustable articulator;

[0037] c. Make arrowhead card 1 and single wall card 3 on the buccal sides of the upper jaw, and make interproximal hook 4 on the adjacent surface of the incisors and canines in the lower jaw;

[0038] d. The production scope of occlusal pad 2: including the occlusal surface of the upper jaw and the bilateral occlusal surface of the mandible; the production requirements of occlusal pad 2: first complete the upper occlusal ...

Embodiment 3

[0040] A partial occlusion functional orthodontic device, comprising a maxillary part and a mandibular part. The maxillary part includes arrow clips 1 fixed on the molars on the left and right sides. The molars on the left and right sides correspond to each other and are first molars and / or On the second molars, the single-wall clamps 3 fixed on the left and right sides of the bicuspids are located on the inner guide slope 5 of the bicuspids. The angle between the guide slope 5 and the occlusal surface is 45 degrees, and the direction of inclination is opposite to that of the partial jaw. The arrow card 1 is adjacent to the single wall card 3; the guide slope 5 is adjacent to the single wall card 3; the guide slope 5, the single wall card 3 and the arrow card 1 are connected through the occlusal pad 2; The interproximal hook 4 on the tooth, the arrow clip 1 fixed on the canines on the left and right sides, and the guiding slope 5 on the inner side of the bicuspid teeth. The ang...

Abstract

The invention relates to a functional retainer, in particular to an occlusion functional retainer. The functional retainer comprises an upper jaw part and a lower jaw part, wherein the upper jaw part comprises arrow clasps fixed on molars on left and right sides, single-wall clasps fixed on bicuspids on left and right sides, and occlusal pads for connecting the arrow clasps with the single-wall clasps; the lower jaw part comprises interproximal hooks fixed on incisor teeth and canine teeth, arrow clasps fixed on canine teeth on left and right sides, and occlusal pads for connecting the arrow clasps with the interproximal hooks; the upper jaw part and the lower jaw part further comprise guide bevels respectively; the guide bevels are positioned on inner sides of the canine teeth; angles between the guide bevels and occlusal surfaces are 40-60 degrees; an inclination direction is opposite to a deviation mandibular direction. As proved by practice, the occlusion functional retainer provided by the invention can establish new occlusal balance of masticatory muscles rapidly, and has very good clinical application effect and high popularization value.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a functional aligner, and more particularly to a functional aligner for partial occlusion. Background technique [0002] Partial occlusion refers to the incongruity of the upper and lower occlusal side relationship, and the inconsistency of the midline of the teeth. It often causes bilateral facial asymmetry and occlusal relationship disorder, which seriously affects the patient's appearance, chewing, and pronunciation functions, and brings huge physical and psychological consequences to the patient. pressure. The causes of misocclusion are complex, and there is still no unified understanding, but they can be divided into two categories: congenital and acquired. Among the congenital factors, due to embryonic developmental disorders, the three-dimensional development of craniofacial bones on one side is insufficient, the development of both sides is unbalanced, and the jaw grows ec...
