Description

Technical Field

[0001] The utility model relates to the technical field of oral cavity, in particular to an improved posterior teeth depression device. Background Art

[0002] Lowering of posterior teeth: In the oral cavity, due to caries, trauma, etc., individual molars or premolars may be missing. If they are not repaired for a long time, the opposing teeth will elongate. When the patient needs to be repaired or implanted again, the elongated teeth need to be lowered to restore their original height.

[0003] With the improvement of casting technology, cast bands have better fit and comfort than prefabricated bands, and the gap opening technology can be achieved by bending wires. The existing technology mainly uses fixed orthodontic technology or local implant technology to lower individual teeth. Lowering the posterior teeth often requires opening up some gaps for lowering, which is generally achieved by fixed orthodontic bonding brackets, opening up gaps through push springs, and then implanting an implant on the buccal and lingual side of the posterior teeth that need to be lowered to lower the raised molars.

[0004] The disadvantages of the above prior art are as follows:

[0005] 1. Need to wear fixed orthodontic appliances, local problems need to be solved by large-area tooth bonding brackets;

[0006] 2. Fixed brackets are less comfortable, more expensive, and require a longer treatment period;

[0007] 3. It requires implantation of nails on the buccal and lingual sides, which is a traumatic operation and is costly.

[0008] In summary, the utility model designs an improved posterior teeth depression device. Summary of the invention

[0009] In view of the deficiencies in the prior art, the utility model aims to provide an improved posterior teeth lowering device, which can solve local problems locally, save costs, is non-invasive, highly comfortable and highly practical.

[0010] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: an improved posterior teeth lowering device, including a casting belt ring, a U-shaped curve, a traction hook and a rubber band, the two sides of the casting belt ring are bent into a U-shaped curve, the U-shaped curves are welded and fixed by traction hooks, and a rubber band is hung between the traction hooks, and the rubber band is hung through the buccal and lingual sides.

[0011] Preferably, the casting band ring is installed on the front and rear teeth of the teeth that need to be depressed.

[0012] Preferably, the U-shaped curve is adjusted in size by pliers to open up a depressed gap.

[0013] The beneficial effects of the utility model: the utility model has reasonable structural design, local problems are solved locally, cost is saved, no trauma, high comfort and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model is described in detail below with reference to the accompanying drawings and specific implementation methods;

[0015] Figure 1 It is a structural schematic diagram of the utility model;

[0016] Figure 2 This is a schematic diagram of a tooth that needs to be depressed according to the present invention (A is the tooth that needs to be depressed). DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] Reference Figure 1-2 The present specific implementation adopts the following technical scheme: an improved posterior teeth lowering device, comprising a casting band 1, a U-shaped curve 2, a traction hook 3 and a rubber band 4, wherein the U-shaped curve 2 is bent between the two sides of the casting band 1, and the U-shaped curve 2 is welded and fixed by the traction hook 3, and a rubber band 4 is hung between the traction hooks 3, and the rubber band 4 is hung through the buccal and lingual sides.

[0019] It is worth noting that the casting band 1 is installed on the front and rear teeth (adjacent teeth) of the teeth that need to be depressed.

[0020] In addition, the U-shaped curve 2 is adjusted in size by pliers to open up a compression gap.

[0021] The improved posterior teeth depression device of this specific embodiment is to manufacture a cast band ring on the front and rear teeth that need to be depressed, and the middle is bent to open a large curve. The depression gap can be opened by adjusting the size of the curve. A traction hook is welded to the middle connecting part, and a rubber band is hung on the buccal and lingual sides to generate a continuous depression force to depress individual molars. The rubber band can be replaced by the patient every day, and the force generated is more continuous.

[0022] The U-shaped curve 2 of this specific embodiment can be adjusted in shape with pliers, opened a little wider, and the teeth on both sides are pushed outward to form a gap, which is needed for compression. The structural design of this specific embodiment is reasonable, the patient is comfortable to wear, the compression effect is good, and the local problem is solved locally, which saves costs, is non-invasive, has high comfort and strong practicality.

[0023] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
