Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically to an invisible orthodontic device. Background Technology

[0002] Orthodontic technology plays a vital role in modern dentistry. While traditional orthodontic appliances such as metal brackets and wire braces are highly effective, they suffer from poor aesthetics, low comfort, and inconvenience in cleaning. With advancements in medical technology, invisible orthodontic appliances have gained popularity due to their transparency, removability, and aesthetic and comfortable features. However, existing invisible braces are typically flat in structure, relying solely on their own elastic deformation to apply corrective force. This limits their effectiveness in correcting certain complex malocclusions (such as deep overbite and protrusion), particularly in providing sufficient vertical or root-controlling corrective force.

[0003] Furthermore, when four first premolars need to be extracted for orthodontic treatment, a "roller coaster effect" is likely to occur. The "roller coaster effect" refers to the loss of control over tooth movement during the orthodontic process of retracting the anterior teeth, resulting in a series of problems such as distal tilting and rotation of the canines, lingual tilting of the incisors, deepening of the anterior overbite, premature contact of the anterior teeth, mesial tilting of the posterior teeth, and mid-arch open bite. To avoid or reduce the "roller coaster effect," sufficient forces need to be generated in both the posterior (sagittal) and root (vertical) directions in the anterior region to move the teeth. Existing orthodontic appliances require the use of bone screws in both the molar and anterior regions (3-4 bone screws need to be implanted in the maxilla or mandible), which is not only cumbersome to operate and causes more wounds, but also has poor results and a more severe foreign body sensation in the mouth, resulting in poor comfort. Utility Model Content

[0004] The purpose of this invention is to provide an invisible orthodontic device that is simple in structure, easy to use, and can effectively improve the above-mentioned problems.

[0005] The embodiments of this utility model are implemented as follows:

[0006] This utility model provides an invisible orthodontic device, including braces, bone screws, and elastic cords. There are two braces, one covering the upper teeth and the other covering the lower teeth. There are four bone screws, two of which are fixed to the left and right sides of the upper teeth, and the remaining two are fixed to the left and right sides of the lower teeth. The posterior wall of the central incisor region of each brace has an opening with a notch, the edge of which forms a loop, or two hooks are provided on the outer side of the posterior wall of the central incisor region. One end of each elastic cord is connected to a bone screw, and the other end is connected to a loop or hook. There are four elastic cords, each corresponding to a bone screw, used to press the braces tightly against the teeth.

[0007] Furthermore, the bone screws are respectively positioned on the mesial buccal side of the second premolars of the maxillary and mandibular teeth on both sides.

[0008] Furthermore, the occlusal end of the brace has a groove at a position corresponding to the elastic cord, and the elastic cord is engaged in the groove.

[0009] Furthermore, the outer wall of the brace has a groove at a position corresponding to the elastic cord, and the elastic cord is engaged in the groove.

[0010] Furthermore, the cavity of the dental brace used to accommodate the teeth is a dental cavity, and the inner wall of the dental cavity is provided with anti-slip texture.

[0011] Furthermore, the elastic rope is a rubber band.

[0012] Furthermore, the free end of the brace has an arc-shaped structure facing the middle. When the two braces are engaged, the occlusal end faces of the middle sections of the two braces are in contact, there is a gap between the occlusal end faces at the anterior teeth position, and there is also a gap between the occlusal end faces at the terminal molar position.

[0013] The beneficial effects of this utility model are as follows:

[0014] The invisible orthodontic device provided by this invention is easy to use. The free end of the braces has an arc-shaped structure towards the middle. Through the bone screw design on the mesiobuccal side of the second premolar and the cooperation of the elastic cord, the arc-shaped structure and bone screw design here aim to generate forces in both the posterior (sagittal) and root (vertical) directions of the braces in the anterior teeth area, thereby achieving the effect of enhancing the retraction and intrusion of the anterior teeth. It can apply precise traction or pressure to the maxillary and mandibular teeth, greatly avoiding or reducing the need for traditional invisible orthodontic devices. It reduces the "roller coaster effect" and also reduces the number of bone screws used (reducing the use of more than 2 bone screws). It is especially suitable for complex cases that require sagittal or vertical adjustment. It makes up for the deficiency of insufficient corrective force in traditional invisible orthodontic appliances, enhances the corrective force in three dimensions, thereby improving the orthodontic effect and accuracy. At the same time, it greatly improves the efficiency of orthodontic treatment and shortens the treatment time. It also improves the comfort of orthodontic treatment. It is especially suitable for cases that require the extraction of four premolars and extensive retraction of anterior teeth to improve protrusion or severe deep overbite.

[0024] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0025] refer to Figure 1 As shown, this embodiment of the present invention provides an invisible orthodontic device, including braces 1, bone screws 2 and elastic cords 3.

[0026] There are two braces 1, one of which covers the upper teeth and the other covers the lower teeth. The end of the brace 1 closest to the tooth root is the open end, which makes it easy to put the brace 1 on the teeth. The end of the brace 1 opposite to the open end is the occlusal end.

[0027] refer to Figure 2As shown, brace 1 transitions in an arc shape from the two free ends towards the middle. Viewed from the side, brace 1 for the maxilla is a downward-convex arched structure, while brace 1 for the mandibular teeth is an upward-convex arched structure. When brace 1 and brace 1 are occluded together, the occlusal end faces at the positions of the first molar and the second premolar abut against each other, while there is a gap between the occlusal end faces at the positions of the anterior teeth and the terminal molars. This is to reduce the "roller coaster effect" during the retraction of the anterior teeth or to achieve the effect of lowering the upper and lower anterior teeth to open the bite.

[0028] refer to Figure 3 As shown, the posterior wall of the central incisor region of the brace 1 has a notch 11 at its opening end. The edge of the notch 11 forms a loop 12. There are two notches 11, which are distributed in a figure-eight shape, with the smaller end of the figure-eight shape facing the opening end of the brace 1. It should be noted that, in this application, after the brace 1 is put on the teeth, the sidewall that fits against the inner side of the teeth is the posterior sidewall of the brace 1, and the sidewall that fits against the outer side of the teeth is the outer sidewall of the brace 1.

[0029] Of course, in another embodiment, a hook 13 is provided on the outer side of the posterior wall of the central incisor region of the brace 1 (see reference). Figure 4 (As shown).

[0030] Four bone screws 2 are used, two of which are used to fix the maxillary teeth on both sides, and the remaining two are used to fix the mandibular teeth on both sides. The bone screws 2 are typically fixed on the mesiobuccal side of the second premolar, located on the outer side of the tooth. The second premolar is usually the fifth tooth from the incisor. The purpose of the bone screws 2 here is to allow the braces in the anterior region to generate more forces in both the posterior (sagittal) and radicular (vertical) directions simultaneously, thereby enhancing the anterior tooth retraction and radicular intrusion. Additionally, it reduces the number of bone screws required, as normally, achieving both posterior (sagittal) and radicular (vertical) forces in the anterior region requires bone screws 2 in both the molar and anterior regions. In this embodiment, the bone screws 2 are orthodontic micro-implant anchorage screws.

[0031] There are four elastic cords 3, with two hanging on each brace 1. One end of the elastic cord 3 is connected to the bone screw 2, and the other end crosses the occlusal end of the brace 1 and is connected to the ear loop 12 or hook 13. The elastic cord 3 corresponds to the bone screw 2 one by one. In this way, the middle part of the elastic cord 3 presses on the occlusal end of the brace 1. The elastic cord 3 can press the brace 1 tightly against the teeth, thereby fixing the position of the teeth better.

[0032] In this embodiment, the elastic rope 3 is a rubber band, which is made of medical-grade material.

[0033] The occlusal end of the braces 1 has a groove corresponding to the elastic cord 3, and the elastic cord 3 is locked in the groove to prevent the elastic cord 3 from sliding left and right.

[0034] The outer wall of the braces 1 has a groove at the part that corresponds to and contacts the elastic cord 3. The elastic cord 3 is locked in the groove, which can reduce the feeling of a foreign object in the mouth when the patient wears it, making the patient more comfortable.

[0035] The cavity in braces 1 that accommodates the teeth is called a tooth cavity. The inner wall of the tooth cavity is provided with anti-slip texture, which can increase the friction with the tooth surface, thereby enhancing the retention force and reducing the probability of braces 1 falling off.

[0036] The invisible orthodontic device provided in this embodiment is used as follows:

[0037] First, suspend one end of the elastic cord 3 on the ear loop 12, then put the two braces 1 on the upper and lower teeth respectively, and then suspend the other end of the elastic cord 3 on the bone screw 2. The elastic cord 3 presses on the braces 1, which can generate a strong and precise orthodontic force.

[0038] During use, the elastic cord 3 is replaced with a new one every day, the braces 1 is cleaned once or several times a day, and the braces are replaced with a new one every week, thus ensuring cleanliness and comfort during use.

[0039] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
