Embodiment 1

[0023] Such as Figure 1-3 As shown, the present invention is a movable orthodontic device for overall mesial movement of molars, which is characterized in that it includes a retention and connection device 1 made of polymer material of an orthodontic pressure film retainer, and a molar belt ring 3 welded with a traction hook 2 , the elastic rubber ring 4, and the blocking plate 5 at the missing tooth;

[0024] The blocking plate 5 at the missing tooth is integrated with the retaining and connecting device 1 and is located near the moved molar 6, and the blocking plate 5 at the missing tooth is located close to the moved molar 6 occlusal end;

[0025] For the molar belt ring 3 welded with the traction hook 2, the traction hook 2 is bent with a 0.019×0.025 inch stainless steel square wire, and the traction hook 2 is welded on the belt ring 3 with a spot welder;

[0026] The height of the traction hook 2 is at the neck position of the molars, and the opening direction of the t...

Embodiment 2

[0029] The preparation and use method of the active orthodontic device for integral mesial mobile molars of the present invention are as follows:

[0030] The specific method of making an intraoral tooth model is: use dental alginate impression material to make a negative mold of the intraoral teeth, and then use superhard plaster to pour the model on the negative mold. The model is required to be accurate and clear, including teeth, dental arches, Basal bone, transitional folds, palatal vault and other parts.

[0031] Use a split apron to place between the second and third molars, or use 0.8mm copper wire and a split spring to split the teeth.

[0032] The above-mentioned gaps in the plaster model were leveled with ordinary white plaster, the width was about 1 / 3-1 / 2 of the buccal-lingual width of the moved molars 6, and the height was about 1.5-2 mm from the 6 occlusal surfaces of the moved molars.

[0033] The retaining and connecting device 1 is made of orthodontic film re...

Abstract

The invention provides a movable correction appliance for integral mesial moving of a molar tooth, and belongs to the technical field of dental orthodontics. The movable correction appliance comprises a position fixing and connecting device, molar tooth band, an elastic rubber ring and a stopping board, wherein the position fixing and connecting device is manufactured by an orthodontic pressed film retainer high polymer material, traction hooks are welded to the molar tooth band and the elastic rubber ring, and the stopping board is arranged at the position of a missed tooth; and the stopping board at the position of the missed tooth is utilized to change the rotary center of the to-be-moved molar tooth, and the elastic rubber ring is utilized to enable the to-be-moved molar tooth (comprising a tooth root and a dental crown) to move to the mesiocclusion gradually one after another till the molar tooth is integrally moved to a destination position. The movable device is simple in operation, attractive in appearance and comfortable, can provide strong and forceful orthodontic anchorage, and thus the molar tooth is ensured to move integrally and efficiently.

Description

technical field [0001] The invention relates to a dental appliance, in particular to a movable device for integrally moving molars, and belongs to the field of orthodontics. Background technique [0002] The loss of molars, especially the loss of first molars, leads to the elongation of the opposing teeth, the oblique displacement of adjacent teeth, and the greatly reduced chewing efficiency, which seriously affects the quality of life of patients. Currently, the treatment methods for missing teeth include restoration and orthodontic treatment. [0003] There are fixed orthodontics and removable orthodontics to move teeth through orthodontic treatment. Fixed appliances can move teeth as a whole, but they are prone to disadvantages such as loss of anchorage, poor oral hygiene, relatively complicated orthodontic techniques, and unsightly appearance; movable orthodontic devices can overcome the above shortcomings. [0004] In the prior art, Invention Patent No. 201320249511.8...
