[0002] In orthodontic treatment technology, functional correction method is a very effective means of early intervention and early treatment for adolescents. Bimaxillary plate correction technology is a commonly used functional correction method. By covering the occlusal slope of the posterior teeth, the appropriate bite force is transmitted to the dentition and jaw, thereby exerting the maximum functional correction force on the developing dentition. Its correction effect has been widely recognized.
[0003] Because bimaxillary plate correction cannot take into account aesthetics at the same time, an invisible transparent appliance was developed based on the principle of bimaxillary plate correction.

[0047] The present invention will be further described in detail below through specific implementation modes in conjunction with the accompanying drawings.
[0048] Existing dental orthodontic appliances include a maxillary orthodontic appliance body and a mandibular orthodontic appliance body. The maxillary orthodontic appliance body and the mandibular orthodontic appliance body are formed by protruding toward the opposite jaw in the area between the canines and molars to form a jaw pad. The jaw pad is formed with a guide bevel at one end close to the canine or away from the canine. During occlusion, the guide bevels of the jaw pad and the matching jaw pad cooperate to generate a force that pushes the upper jaw backward and a force that stretches the lower jaw forward, thereby stretching the lower jaw forward.
[0049] Because the jaw pad and the matching jaw pad are hollow structures, the jaw pad and the matching jaw pad are often broken due to the bite force, and the interaction force of the guide bevel between the jaw pad and the matching jaw pad will cause the lower front teeth to tilt lip. In addition, because the jaw pad and the matching jaw pad are fitted through the guide bevel, it is difficult to achieve a stable bite in the jaw pad of the premolar area in practical applications, which often leads to relapse after correction.
[0050] Based on the above-mentioned problems existing in the dental appliance, the present invention provides another structure of a dental appliance with an occlusal guide, which can change the occlusal plane of the upper and lower jaws, inductively change the position of the mandible during occlusion, and ultimately achieve a stable new position of the mandible through correction of the dentition by the dental appliance.
[0051] The structural diagram of the dental appliance of the present invention is as follows Figure 1As shown, it includes a maxillary appliance body 100 and a mandibular appliance body 200. The occlusal surfaces of the front and rear teeth of the maxillary appliance body 100 form an occlusal plane, and the occlusal surfaces of the front and rear teeth of the mandibular appliance body 200 form an occlusal plane. When the maxillary appliance body 100 and the maxillary appliance body 200 are in the occlusal process, the front and rear teeth of the upper and lower jaws are in an occlusal state, and the protrusion and / or lateral movement of the mandible are induced and guided by the natural occlusal force.
[0052] Here, the effect of the dental appliance on the induced advancement of the mandible is explained by taking mandibular retraction as an example.
[0053] A typical diagram of mandibular retrusion is shown below. Figure 1 As shown in the figure, the mandibular occlusal surface of the mandibular retrusion is a downward arc; because the mandible can only be extended forward when the mouth is open, but it cannot bite when it is extended forward, such as Figure 2 As shown in the figure, if the upper and lower jaws bite when the mandible is protruding, the two ends of the upper and lower jaws will collide, and the middle parts of the upper and lower jaws will be separated, that is, the mandible cannot achieve a stable and comfortable bite when it is in the protruding position. Figure 3 shown.
[0054] A stable and comfortable occlusion can only be achieved when the occlusal surfaces of the upper and lower jaws match. Therefore, the present invention manufactures a maxillary appliance body 100 and a mandibular appliance body 200 with corresponding correction functions based on the maxillary and mandibular dentition data, and compensates the maxillary appliance body 100 and the mandibular appliance body 200 through a compensation element, so that the occlusal surfaces of the front and rear teeth of the maxillary appliance body 100 form an occlusal plane after compensation by the maxillary compensation element 101, and the occlusal surfaces of the front and rear teeth of the mandibular appliance body 200 also form an occlusal plane after compensation by the mandibular compensation element 201. When the compensated maxillary appliance body 100 and the mandibular appliance body 200 are made into products and applied to patients with mandibular retraction, when the patient's mandible protrudes forward and occludes with the maxilla, a stable occlusal surface can be formed between the upper and lower jaws, such as Figure 4 shown.
[0055] By compensating for the occlusal surfaces of the upper and lower mandibular appliance bodies, when the patient's mandible protrudes and occludes with the upper jaw, a stable occlusal surface can be formed between the upper and lower jaws. The maxillary compensation element 101 occludes with the plane of the mandibular appliance body 200 corresponding to it below, and the mandibular compensation element 201 occludes with the plane of the maxillary appliance body 100 corresponding to it above, thereby maintaining a comfortable occlusal experience for the patient. At the same time, through the cooperation between the mandibular compensation element 201 and the appliance body corresponding to it above, and the cooperation between the maxillary compensation element 101 and the appliance body corresponding to it below, the mandibular protrusion can be induced.
[0056] During the correction process, the dental appliance body simultaneously depresses the anterior and posterior teeth of the mandible, so that the maxillary compensation element 101 and the mandibular compensation element 201 are gradually reduced. The maxillary compensation element 101 and the mandibular compensation element 201 are a way to obtain a planar occlusion when the mandibular occlusal plane is not formed. Therefore, the collision of the upper and lower jaws and the discomfort of the occlusion are avoided throughout the treatment. When the entire correction cycle is over, the mandibular occlusal surface will eventually become a planar occlusion, and the mandibular and maxillary dentitions will form a stable and comfortable occlusion after protrusion. Figure 5 shown.
[0057] In order to achieve the above effects, the specific structure of the maxillary appliance body 100 is described as follows.
[0058] like Figure 6 As shown, the maxillary appliance body 100 is in the shape of an integral shell, and has a cavity for accommodating maxillary teeth, and the cavity can accommodate at least a portion of the teeth of the maxillary dentition, so that the geometry of the cavity substantially matches the corresponding portion of the maxillary dentition, so that the maxillary appliance body can be worn and fixed on the maxillary dentition. In some embodiments, the cavity of the maxillary appliance body 100 can accommodate the entire maxillary dentition.
[0059] Unlike the traditional maxillary appliance body, the traditional maxillary appliance body has the problem of inconsistent occlusal surfaces of the front and rear teeth, that is, the occlusal surfaces of the front and rear teeth are not in the same plane, while the occlusal surfaces of the front and rear teeth of the maxillary appliance body 100 of the present invention form an occlusal plane.
[0060] Specifically, the maxillary appliance body 100 is provided with a maxillary compensation element 101 for compensating the occlusal surface of the maxillary teeth, and the maxillary compensation element 101 is used to make the occlusal surface of the front teeth and the occlusal surface of the back teeth of the maxillary appliance body 100 form a unified occlusal plane. According to the physical characteristics of the maxillary teeth, when the maxillary compensation element 101 is specifically designed, the occlusal surface of the maxillary anterior teeth is used as the reference plane, and the tangent line of the occlusal surface of the maxillary anterior teeth is used as the reference line. The thickness of the maxillary compensation element 101 is designed according to the distance between the reference line and the maxillary molars, so that after the partial area of the maxillary molar area of the maxillary appliance body 100 is compensated by the designed maxillary compensation element 101, the occlusal surface of the front teeth and the occlusal surface of the back teeth of the compensated maxillary appliance body 100 form a unified occlusal plane.
[0061] In order to achieve a personalized design of the maxillary appliance body 100, the shape of the maxillary compensation element 101 in this example is not limited, but the side of the maxillary compensation element 101 facing the jaw is flat or approximately flat. The material of the maxillary compensation element 101 is also not limited, for example, the material of the maxillary compensation element 101 can be plastic, silicone, or a diaphragm.
[0062] The maxillary compensation element 101 is integrally formed with the maxillary appliance body, for example, by 3D printing. The maxillary compensation element 101 can be a solid structure or a cavity structure.
[0063] The specific structure of the mandibular appliance body 200 is described as follows.
[0064] like Figure 7 As shown, the mandibular appliance body 200 is in the shape of an integral shell, and has a cavity for accommodating mandibular teeth, and the cavity can accommodate at least a portion of the mandibular dentition. Therefore, the geometry of the cavity substantially matches the corresponding portion of the mandibular dentition, so that the mandibular appliance body 200 can be worn and fixed on the mandibular dentition. In some embodiments, the cavity of the mandibular appliance body 200 can accommodate the entire mandibular dentition.
[0065] Unlike the traditional mandibular appliance body, the traditional mandibular appliance body has the problem of inconsistent occlusal surfaces of the front and rear teeth, that is, the occlusal surfaces of the front and rear teeth are not in the same plane, while the occlusal surfaces of the front and rear teeth of the mandibular appliance body 200 of the present invention form an occlusal plane.
[0066] Specifically, the mandibular appliance body 200 is provided with a mandibular compensation element 201 for compensating the occlusal surface of the mandibular teeth, and the mandibular compensation element 201 is used to make the occlusal surface of the front teeth and the occlusal surface of the back teeth of the mandibular appliance body 200 form a unified occlusal plane. According to the physical characteristics of the mandibular teeth, when the mandibular compensation element 201 is specifically designed, the occlusal surface of the mandibular front teeth is used as the reference plane, and the tangent line of the occlusal surface of the mandibular front teeth is used as the reference line. The thickness of the mandibular compensation element 201 is designed according to the distance between the reference line and the mandibular molars, so that after the area between the mandibular molar area and the mandibular canine area of the mandibular appliance body 200 is compensated by the designed mandibular compensation element 201, the occlusal surface of the front teeth and the occlusal surface of the back teeth of the mandibular appliance body 200 after compensation form a unified occlusal plane.
[0067] In order to achieve a personalized design of the mandibular appliance body 200, the shape of the mandibular compensation element 201 in this example is not limited, but the side of the mandibular compensation element 201 facing the jaw is flat or approximately flat. The material of the mandibular compensation element 201 is also not limited, for example, the material of the mandibular compensation element 201 can be plastic, silicone, or a diaphragm.
[0068] The mandibular compensation element 201 is integrally formed with the mandibular appliance body 200, such as by 3D printing. The mandibular compensation element 201 can be a solid structure or a cavity structure.
[0069] According to the structural design of the upper and lower jaw appliance bodies 100 and 200, please continue to refer to Figure 4During the occlusion process, the occlusal plane of the maxillary appliance body 100 and the occlusal plane of the mandibular appliance body 200 place the front and rear teeth of the upper and lower jaws in an occlusal state to guide the front-to-back direction and / or left-to-right direction of the upper and lower jaws.
[0070] Furthermore, in order to make the dental appliance have not only the function of occlusal guidance but also the function of tooth arrangement, the maxillary appliance body 100 of this example has a geometric shape for repositioning the selected maxillary teeth from the original maxillary tooth layout to the first maxillary tooth layout. Similarly, the mandibular appliance body 200 also has a geometric shape for repositioning the selected mandibular teeth from the original mandibular tooth layout to the first mandibular tooth layout.

[0075] The thickness of the first maxillary appliance body, the middle maxillary appliance body, and the maxillary compensation element on the final maxillary appliance body is gradually reduced as the maxillary teeth layout is successively adjusted.
[0076] In some embodiments, if it is necessary to adjust the mandibular tooth layout and the relative position of the upper and lower jaws at the same time, the dental appliance may include a plurality of mandibular appliance bodies and at least one maxillary appliance body, wherein the mandibular appliance bodies include:
[0077] A first mandibular appliance body, wherein the first mandibular appliance body is provided with a first mandibular compensation element for compensating the occlusal surface of the mandibular teeth, the first mandibular compensation element enables the occlusal surface of the front teeth and the occlusal surface of the back teeth of the first mandibular appliance body to form a unified occlusal plane, and the cavity of the first mandibular appliance body for accommodating teeth has a geometric shape for repositioning the selected mandibular teeth from the original mandibular tooth layout to the first intermediate mandibular tooth layout;
[0078] One or more intermediate mandibular appliance bodies, wherein the intermediate mandibular appliance bodies are provided with intermediate mandibular compensation elements for compensating the occlusal surfaces of the intermediate mandibular teeth, wherein the occlusal surfaces of the front teeth and the occlusal surfaces of the rear teeth of the intermediate mandibular appliance bodies are formed into a unified occlusal plane by the intermediate mandibular compensation elements, and the cavities of the intermediate mandibular appliance bodies for accommodating teeth have a geometric shape for successively repositioning selected maxillary teeth from a first intermediate mandibular tooth layout to a subsequent intermediate mandibular tooth layout;
[0079] A final mandibular appliance body, wherein the final mandibular appliance body is provided with a final mandibular compensation element for compensating the occlusal surface of the final mandibular teeth, wherein the occlusal surface of the front teeth and the occlusal surface of the back teeth of the final mandibular appliance body form a unified occlusal plane through the final mandibular compensation element, and the cavity of the final mandibular appliance body for accommodating teeth has a geometric shape for repositioning the selected mandibular teeth from the final intermediate mandibular tooth layout to the final mandibular tooth layout;
[0080] The thickness of the first mandibular appliance body, the middle mandibular appliance body, and the mandibular compensation element on the final mandibular appliance body is gradually reduced as the mandibular tooth layout is successively adjusted.

The cavities of the multiple maxillary appliance bodies that accommodate the maxillary teeth have a geometric shape that adjusts the selected maxillary teeth one by one from the original maxillary tooth layout to the final maxillary tooth layout.
[0082] Taking mandibular retraction as an example, the difference in the specific working principle between the dental appliance of the present invention and the traditional dental appliance is further explained.
[0083] Since the mandibular retraction is mainly caused by the existence of inconsistent occlusal planes, which makes the mandible bite in the posterior position, the dental appliance of the present invention corrects the inconsistent occlusal plane into a consistent occlusal plane through the compensation element, and the front and rear tooth occlusal surfaces of the maxillary appliance body and the mandibular appliance body respectively form an occlusal plane, so that the front and rear teeth of the upper and lower jaws can bite in the occlusal state, and the mandible is guided to protrude forward when biting, so as to guide the mandible in a natural occlusal state, such as Figure 4 As shown; the traditional dental appliance forces the mandible to be stretched by the guide bevel; therefore, the dental appliance of the present invention changes the position of the mandible during occlusion by changing the upper and lower jaw occlusal platforms, and at the same time corrects the dentition through the appliance, ultimately achieving a stable new mandibular position.
[0084] The specific application of the dental appliance of the present invention to the lateral induction of the mandible is described below by taking the case of functional mandibular deviation as an example, wherein the lateral induction can be either the left induction of the mandible or the right induction of the mandible.
[0085] Functional mandibular deviation is caused by the mismatch between the maxillary and mandibular dental arch widths. If the patient wants to achieve a good bite, he will lean to one side, resulting in a unilateral bite. Arch width mismatch usually results in a palatal tilt of the posterior teeth on both sides and a palatal tilt of the posterior teeth on one side. Therefore, the present invention adopts a technical solution to compensate for the maxillary dental arch width. For details, please refer to Figure 8 and Fig. 9 , where the compensation diagram for the narrow maxillary dental arch is shown in Figure 8 The schematic diagram of compensation for mandibular dental arch narrowness is shown in Fig. 9 As shown, no matter the mandibular dental arch is narrow or the maxillary dental arch is narrow, the present invention sets a compensating element at the corresponding position on the mandibular orthodontic appliance body, so that the upper and lower jaws have a stable occlusal plane after wearing the orthodontic appliance. Through this occlusal plane and in combination with the correction function of the orthodontic appliance body, the maxillary dental arch width can be corrected, or the palatal inclination of the posterior teeth on one side can be corrected. The final correction effect can enable the corrected upper and lower jaws to obtain a stable occlusal plane.
[0086] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not used to limit the present invention. For those skilled in the art to which the present invention belongs, some simple deductions, modifications or substitutions can be made according to the idea of the present invention.
