Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, and in particular relates to an invisible orthodontic appliance. Background Art

[0002] Bracketless invisible braces are a type of orthodontic device that has more advantages than traditional fixed appliances. They are invisible and transparent, have better aesthetics, are comfortable to wear, have gentle force, cause little pain, do not affect oral movement, and do not irritate the oral mucosa. They are also convenient for oral hygiene maintenance and can be removed and put on at any time without affecting cleaning. In addition, after using invisible braces, the frequency of follow-up visits is low, the intervals are long, and the follow-up operation is simple.

[0003] The basic principle of invisible braces to move teeth is to tightly wrap the part of the teeth exposed in the mouth and move the teeth through the deformation of the braces. Therefore, the effective retention of the braces is the basis for applying accurate orthodontic force to the teeth. Insufficient retention force not only fails to ensure that the braces are effectively wrapped on the teeth, making the braces easy to loosen and fall off, but may also cause uncontrollable movement of teeth, increase the difficulty of correction and cause unpredictable risks of tooth periodontitis.

[0004] At present, the orthodontic appliance is retained clinically by placing accessories on the labial or lingual side of the teeth. However, the retention accessories are regular in shape and usually large in size, so they are not easy to bond, and they are likely to cause discomfort to the patient during bonding. They may also cause plaque accumulation, enamel demineralization, and caries. In addition, the current clinical orthodontic treatment process is relatively long, and long-term removal and wearing of orthodontic appliances will cause the accessories to wear or even fall off. If they are not repaired in time, it will affect the effect of tooth movement and increase the frequency of patient follow-up visits. Utility Model Content

[0005] In order to solve the above technical problems, the utility model discloses an invisible orthodontic appliance, which can avoid the need for accessories and enable the appliance to have a higher retention force to achieve a tooth orthodontic effect.

[0006] The specific technical solution of the utility model is as follows:

[0007] An invisible brace appliance, comprising:

[0008] An appliance body for accommodating teeth, wherein the appliance body is provided with a slot; and

[0009] The buckle cooperates with the slot and is used to be snapped into the gap between adjacent teeth.

[0010] For patients whose posterior teeth crowns do not have enough space to bond retention accessories or whose posterior teeth retention accessories are difficult to bond, the setting of the accessories cannot meet the specific usage requirements, which will affect the actual effect of orthodontics. To address this defect, the present application provides a slot on the appliance body, and uses the slot to determine the position of the buckle, so that the buckle can be stably connected between adjacent teeth, so as to directly retain the posterior teeth through the buckle, thereby improving the expression rate of the corrective force of the appliance, thereby achieving stable orthodontics. At the same time, the present application does not need to set up accessories separately. Therefore, during the correction process of the patient, there is no need to consider the retention space of the patient's posterior teeth. Therefore, on the basis of ensuring that the appliance and the teeth are more closely fitted, the disassembly and assembly time of the appliance is effectively reduced.

[0011] Preferably, the buckle is a hemispherical structure, a hemispherical structure, a triangular structure, an inverted triangular structure, a diamond structure, a hook structure, an elliptical structure, or a teardrop structure.

[0012] The structure of the buckle is simple and practical, and can work well between two adjacent teeth on the basis of cooperating with the slot, thereby ensuring the limitation of the appliance body and meeting the correction requirements.

[0013] Preferably, the buckle is a hemispherical structure, and the radial cross-section of the buckle is circular.

[0014] The hemispherical structure occupies a small space, has a high degree of fit with the gap between teeth, and is easy to adjust the clamping position during the installation of the orthodontic appliance, which helps to improve installation efficiency.

[0015] Preferably, the maximum diameter of the buckle does not exceed 3 mm.

[0016] When using the present application, if it is used for deciduous teeth, it is not conducive to the retention of the appliance body due to the small gaps between the deciduous teeth.

[0017] Preferably, the buckle is arranged obliquely to the corrector body.

[0018] The buckle arranged obliquely to the orthodontic appliance body can be better clamped between adjacent teeth, and better provide retention force for the orthodontic appliance body, thereby ensuring that the orthodontic appliance can provide the teeth with the correction force required for orthodontics.

[0019] Preferably, an abutment portion is provided at the end of the buckle, and the abutment portion has a smooth structure and is used to contact the upper edge of the gingival papilla.

[0020] After the braces are installed, since the buckle will be clamped between adjacent teeth, the buckle will better position the braces body in combination with the upper edge of the gingival papilla, ensuring that the buckle can provide good retention force for the braces body, thereby better enabling the braces body to provide correction force for the teeth.

[0021] Preferably, the appliance body has an accommodating cavity for accommodating teeth, and the structure of the accommodating cavity matches the current layout of the tooth arrangement, or matches the target layout of the tooth arrangement.

[0022] Use the orthodontic body with the corresponding accommodating cavity structure according to actual conditions to meet different correction needs.

[0023] Preferably, the accommodating cavity is used to accommodate a part of or all of the teeth arranged in succession.

[0024] The orthodontic device of the present application can be used for local correction or overall correction.

[0025] Preferably, the appliance body and the buckle are integrally formed by a hot pressing film process.

[0026] The structure is easy to manufacture and use, and can well meet actual correction needs.

[0027] Preferably, the buckle is bonded to the appliance body.

[0028] The buckle and the appliance body can be manufactured separately and then connected by bonding, which can better meet the adjustment of the retention position.

[0029] Compared with the prior art, the utility model can set the orthodontic appliance body for the upper and lower jaws according to the actual conditions according to the needs of correction, and avoid bonding and fixing accessories, thereby reducing the doctor's chairside operation time, improving the expression rate of correction force, and enhancing the patient's comfort and aesthetics during wearing.

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0037] like Figure 1 As shown, an invisible braces includes a braces body 100 for accommodating teeth, and a buckle 101; the braces body 100 is provided with a slot; the buckle 101 cooperates with the slot to be clamped in the gap between adjacent teeth. In this embodiment, the accommodating cavity is used to accommodate a part of the teeth or all the teeth arranged in a row. This embodiment is described in detail with the accommodating cavity being used to accommodate all the teeth arranged in a row. It can be seen that when the accommodating cavity is used to accommodate a part of the teeth arranged in a row, the use principle is the same as that of accommodating all the teeth.

[0038] The arc-shaped shell of the orthodontic body 100 can accommodate the teeth on the basis of matching the arrangement of the teeth. In the present embodiment, the two ends of the orthodontic body 100 are respectively located at the posterior teeth. The card slots have four locations, which are respectively arranged at the two ends of the orthodontic body 100. Specifically, the card slots are specifically opened on the lingual and buccal sides of the interproximal space area between the anterior teeth and the posterior teeth. It can be seen that the buckle 101 is also located on the lingual and buccal sides of the interproximal space area between the anterior teeth and the posterior teeth. The orthodontic body 100 in the present embodiment is made of a transparent material. Therefore, after the patient wears the orthodontic appliance, it can improve the wearing aesthetics on the basis of meeting the correction needs.

[0039] like Figure 2 to Figure 5 As shown, in different technical solutions of this embodiment, the buckle 101 is a semi-spherical structure or a semi-spherical structure or a triangular structure or an inverted triangular structure or a diamond-shaped structure or a hook-shaped structure or an elliptical structure or a water drop-shaped structure. When the buckle 101 is a semi-spherical structure, the radial cross-section of the buckle 101 is circular, and the retention effect is better at this time. If the gap between the teeth is large, the buckle 101 with a diamond-shaped structure is preferred, which can well meet the use requirements. When the buckle 101 adopts a hook-shaped structure, the cross-section of the hook part of the buckle 101 is triangular, which can provide better stability.

[0040] In this embodiment, when this embodiment is used for deciduous teeth, since the gaps between deciduous teeth are small, the maximum diameter of the buckle 101 does not exceed 3 mm.

[0041] In order to better use this embodiment, the buckle 101 is arranged obliquely to the appliance body 100. That is to say, the buckle 101 is clamped between adjacent teeth at an angle, and at the same time, an abutment portion is arranged at the end of the buckle 101, and the abutment portion has a smooth structure and is used to contact the upper edge of the gingival papilla. Thus, the angle-shaped triangular support provides a better retention ability for the appliance body 100. It is known that the smooth abutment portion can maintain a good retention ability under the limitation of the card slot and well avoid damage to the upper edge of the gingival papilla.

[0042] In this embodiment, the appliance body 100 has a receiving cavity for accommodating teeth, and the structure of the receiving cavity matches the current layout of the tooth arrangement, or matches the target layout of the tooth arrangement. When the structure of the receiving cavity matches the current layout of the tooth arrangement, correction retention can be achieved, and when the structure of the receiving cavity matches the target layout of the tooth arrangement, orthodontic correction can be well achieved.

[0043] In different technical solutions, the manufacturing methods of the appliance body 100 and the buckle 101 are also different. The two can be integrally formed. Specifically, the appliance body 100 and the buckle 101 are integrally formed by a hot pressing film process. The two can also be manufactured separately. After being manufactured, the buckle 101 is bonded to the appliance body 100. It can be seen that no matter which method is used to form the appliance, it can meet the actual use requirements.

[0044] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
