Description

Technical Field

[0001] The utility model relates to the technical field of tooth correction, in particular to a bracket-free invisible correction device for treating malocclusion of teeth. Background Art

[0002] Bracketless invisible braces are a computer-aided design and manufacturing process using transparent elastic materials for removable correction. They are a series of continuous braces that achieve correction through continuous, small tooth movements. They can control not only the magnitude of the corrective force but also the duration of the force. Depending on the stage, only certain teeth can be moved, while others act as support, completing the correction.

[0003] Chinese Patent Publication No.: CN213851156U discloses a bracketless invisible braces, including a dental mold and a brace covering the surface of the dental mold, the edges of which extend more than 3mm to the labial and buccal sides and the lingual and palatal sides on the basis of the original covering crown, forming a bilateral wrap-around invisible braces. The extension of the palate can cover the entire palate or part of the palate. After the braces are worn in the mouth, they are lightly attached to the surface of the soft tissue in whole or in part, or raised a certain distance. Compared with traditional invisible braces, the invisible braces of the utility model have a more adequate wrapping of the teeth, and the force applied by the braces is closer to the impedance center of the teeth, thereby improving the expression efficiency of the invisible braces in moving teeth;

[0004] This technical solution has poor anti-slip performance, and the braces are easy to fall off after being put on the teeth. At the same time, during use, this technical solution will cause a small displacement of the upper and lower jaws due to inter-maxillary traction and tooth force, which will eventually affect the correction effect on the user's teeth. Utility Model Content

[0005] The purpose of the present invention is to provide a bracketless invisible orthodontic device for treating malocclusion of teeth, so as to solve the problems raised in the above-mentioned background technology.

[0006] In view of the above problems, the technical solution proposed by the present invention is:

[0012] Furthermore, a second positioning block is installed on the bottom surface of the limit block, and a plurality of second positioning grooves are opened on the top surface of the second body. The second positioning block is engaged with the second positioning grooves, and the second positioning block is connected to the anti-slip sleeve in the second body.

[0013] Furthermore, the interiors of the limit block and the second positioning block are each provided with a third through hole that is interconnected, the top surface of the limit block is provided with a countersunk hole that is connected to the third through hole, and the bottom surface of the second positioning groove is provided with a fourth through hole, and a second screw is slidably provided inside the countersunk hole, the third through hole, and the fourth through hole, and the second screw is threadedly engaged with the threaded hole.

[0014] The beneficial effect of adopting the above further scheme is that the limit block, the second body and the anti-slip cover can be separated by using the second screw, the third through hole, the fourth through hole and the threaded hole, so that the user can clean and disinfect the limit block, the second body and the anti-slip cover to prevent bacteria from growing therein.

[0015] Furthermore, the screw head of the first screw slides in the countersunk hole, and the screw head of the second screw is located in the countersunk hole.

[0016] The beneficial effect of adopting the above further solution is that the countersunk hole is used to prevent the screw head of the second screw from being exposed. At the same time, after the patient's teeth are bitten together, the screw head of the first screw will move into the countersunk hole to prevent the screw head of the first screw from affecting the bite of the correction target.

[0017] Furthermore, the number of the first positioning groove, the first positioning block, the threaded hole, the limiting sleeve, the limiting block, the second positioning groove, and the second positioning block is the same.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the bracketless invisible orthodontic device for treating a type of malocclusion of teeth can absorb saliva on the target teeth through the use of anti-slip parts, thereby increasing the friction between the anti-slip parts and the teeth, and can increase the pressure of the anti-slip parts on the teeth through the use of protrusions, thereby preventing the anti-slip parts from detaching from the teeth; when using the device, after the teeth of the target teeth are bitten, the limit block will be stuck in the limit sleeve, thereby preventing the upper and lower corrective parts from offsetting due to inter-maxillary traction and tooth force, thereby improving the correction effect on the target teeth.
