Description

Technical Field

[0001] The invention relates to the technical field of oral medical correction devices, and in particular to a dual mechanical system dynamic long molar lowering correction device. Background Art

[0002] In oral clinics, it is common to see excessive elongation of the opposing teeth due to long-term loss of molars on one side. Traditional solutions include crown cutting and molar depression. The crown cutting method is to cut the crown after root canal treatment of the elongated molar, and then perform crown restoration to obtain restoration space. This method is at the expense of the vitality of the healthy tooth pulp, and a large amount of healthy tooth tissue is removed. In addition, the root canal effect of the posterior teeth is uncertain, which is not easily accepted by patients. The molar depression method includes removable appliance correction and full-mouth fixed correction. Full-mouth fixed correction has an unsatisfactory effect of bending the teeth horizontally at the end of the archwire, and the complex archwire bending is not conducive to the maintenance of oral hygiene. It is difficult to avoid extending the supporting teeth while depressing the elongated molars. The correction treatment time is long, and full-mouth brackets need to be bonded. The aesthetics is poor, which is unacceptable to many adult patients who only want to repair missing teeth. Therefore, it is urgent to design a simple and easy-to-use dual mechanical system dynamic long molar depression appliance. Summary of the invention

[0003] In order to solve the above problems, the present invention designs a dual mechanical system dynamic long molar depression orthodontic appliance.

[0004] In order to solve the above technical problems and achieve the above technical effects, the present invention is implemented through the following technical contents:

[0005] A dual mechanical system dynamic long molar lowering appliance, comprising a vacuum lamination dental brace and a traction piece, wherein the vacuum lamination dental brace and the traction piece are detachable and installable;

[0006] The molar model of the vacuum lamination dental brace is provided with a magnetic depression area at the upper end, an X-shaped depression opening is provided on the magnetic depression area, and a traction hook model is provided on the jaw side and the buccal side of the molar model, and the traction hook model is hollow inside and provided with a fixed magnetic sheet;

[0007] The traction member includes an elastic rubber band, a depression magnetic sheet and a traction magnetic sheet. The elastic rubber band is cross-fixed on the traction hook model and is located in the depression opening. The depression magnetic sheet is arranged in the magnetic depression area below the depression opening. The traction magnetic sheet is arranged in the traction hook model.

[0008] Furthermore, the magnetic depression area and the traction hook model are integrally formed with the vacuum lamination braces.

[0009] Furthermore, two traction hook models are respectively arranged on the jaw side and the buccal side of the molar model.

[0010] Furthermore, the traction magnetic sheets are provided with a plurality of sheets, and have a variety of magnetic force specifications, so as to fill the traction hook model.

[0011] Another object of the present invention is to provide a method for using a dual mechanical system dynamic depressing long molar orthodontic appliance, which specifically comprises the following steps:

[0012] Step 1: Make plaster models of the upper and lower jaws where the patient's long molars are located

[0013] Step 2: Place a depressing magnetic sheet above the long molars of the plaster model, fix traction hooks on the long palatal and buccal sides of the molars, use a hot pressing film forming machine to press a vacuum pressing brace according to the long molar plaster model, form a magnetic depressing area at the position where the depressing magnetic sheet is placed, and form a traction hook model at the traction hook position.

[0014] Step three, make an X-shaped opening in the magnetic depression area above the long molars of the vacuum pressed braces after molding, and set a fixed magnetic sheet in the traction hook model.

[0015] Step 4: Place a depression magnetic sheet in the magnetic depression area and fill the traction magnetic sheet in the traction hook model.

[0016] Step 5: Wear the vacuum lamination braces on the long molar side of the patient's mouth, and use elastic rubber band X-shaped fixation and traction hook model to press down the magnetic plate.

[0017] Step six: Check regularly and replace elastic rubber bands with different pulling forces and traction magnets with different magnetic forces and quantities according to the compression requirements.

[0018] The beneficial effects of the present invention are:

[0019] (1) The present invention combines magnetic force with elastic pressure to correct molar depression, which can increase the correction speed and dynamically fine-tune the correction direction and strength to improve the correction effect. Different elastic bands of different tightness can provide vertical downward pressure of different strengths to act on the long molars, and by replacing the traction magnetic sheets and depression magnetic sheets of different magnetic strengths in the traction hook model at different positions, the pressure strength and offset of depression in different directions can be flexibly adjusted, and the depression effect of the molars can be dynamically and flexibly adjusted during the entire molar depression process.

[0020] (2) The present invention has a simple structure and is easy to use. The braces structure is easy for patients to wear and does not require surgical treatment to relieve pain. Compared with other correction methods, it does not require the use of arch wires, thereby improving comfort in the oral cavity.

[0021] (3) The present invention is highly targeted and can correct the depression of a single or multiple molars according to the correction requirements. When manufacturing the vacuum lamination braces, a traction hook model can be formed according to the position of the molar to be corrected. BRIEF DESCRIPTION OF THE DRAWINGS
