[0002] This disclosure claims priority to a Chinese patent application entitled "Orthodontic System for Oral Treatment" filed on December 28, 2022, application number 202223509631.5, the entire contents of which are incorporated herein by reference.

[0003] The embodiments of the present application relate to the technical field of dental orthodontics, and in particular to an oral treatment orthodontic system and a method for producing the same, an electronic device, and a storage medium. [Background technology]

[0004] In the prior art, early malocclusion is treated mainly using silicone orthodontic appliances made of medical-grade silicone material. These orthodontic appliances are early orthodontic appliances that utilize growth and development to correct malocclusion. They are characterized by their beautiful appearance and comfortable wearing, and avoid problems such as children refusing to wear the orthodontic appliances due to discomfort, which can lead to poor physical and mental development. As a result, an increasing number of people are using silicone orthodontic appliances as early malocclusion correctors.

[0005] In traditional oral treatment for children, doctors match a silicone orthodontic appliance to a patient based on the size of the patient's current dental arch to perform treatment. Traditional products usually provide doctors with several sizes to choose from, so the size of the silicone orthodontic appliance is relatively fixed and cannot be accurately customized according to the patient's oral cavity and dentition conditions. Similarly, it cannot solve the problem of deep bite or crossbite in malocclusion, and the silicone orthodontic appliance applies excessive corrective force to the teeth, causing undesired lip and lingual tilting of the teeth in the anterior region or problems of proximal or retrorotation of the mandible, often resulting in orthodontic failure.

[0006] Therefore, there is a need to provide a treatment device that more precisely controls sagittal movement of the jaw segments. Summary of the Invention

[0025] In order to clarify the objectives, technical solutions, and advantages of the embodiments of the present application, the embodiments of the present application will be described in detail below in conjunction with the drawings. However, those skilled in the art will understand that many technical details are presented in the embodiments of the present application to help readers better understand the present application. However, the technical means sought to be protected by the present application can be realized without these technical details and various changes and modifications based on the following embodiments. The division of the following embodiments is for ease of explanation and should not be construed as imposing any limitations on the specific implementation manner of the present application. The embodiments may be cited in combination with each other as long as they are not inconsistent.

[0026] The "posterior tooth region" according to each example of the present application is based on the definition of tooth types in pp. 36-38 of "Guidelines for Oral Medicine," Second Edition, published by Peking University Medical Press, and includes premolars and molars, corresponding to teeth numbered 4-8 in the FDI notation. The anterior tooth region is based on the definition of tooth types in pp. 36-38 of "Guidelines for Oral Medicine," Second Edition, published by Peking University Medical Press, and includes teeth numbered 1-3 in the FDI notation. The teeth in the anterior tooth region include central incisors, lateral incisors, and canines. Regarding teeth in the primary tooth stage, the "posterior tooth region" is based on the definition of primary tooth types in pp. 40-41 of "Guidelines for Oral Medicine," Second Edition, published by Peking University Medical Press, and includes three types of teeth: primary incisors, primary canines, and primary molars. The primary incisors include the primary central incisors and primary lateral incisors, and the primary molars include the first and second primary molars.

[0027] Research has shown that mandibular prognathism promotes the growth rate and volume of condylar chondrocytes, enhances the functional activity of the pterygoid muscles, and increases mandibular length. Furthermore, research has found that the stress and displacement of the condylar cartilage surface are significantly and positively correlated with mandibular prognathism and jaw opening distance. This suggests that the distance of mandibular prognathism should not be too large to avoid excessive stress distribution on the condylar surface, which would exceed the body's adaptive capacity and cause pathological damage. Conventional silicone mouthpieces do not address this issue, instead simply leading the mandible to the incisal occlusion position of the anterior teeth. The oral treatment orthodontic system described herein provides gradual prognathism for patients with severe sagittal imbalance and deep bite. Gradual prognathism is more beneficial for reconstructing condylar tissue and making it easier for patients to adapt.

[0028] Therefore, in the prior art, when silicone orthodontic appliances are used to treat cases of early malocclusion, excessive corrective forces are applied to the teeth, resulting in undesirable labial and lingual inclination or pro- or retro-rotation of the mandible in the anterior region, and effectively reconstructing the condylar tissue. This application proposes an orthodontic system for oral treatment. As shown in FIG. 1 , one embodiment of the orthodontic system for oral treatment is designed to gradually realize a treatment plan and includes a series of orthodontic appliances, including at least a first orthodontic appliance 1 and a second orthodontic appliance 2. The first orthodontic appliance 1 and the second orthodontic appliance 2 may be made of a polymer material, which may be a siloxane polymer or a silane polymer. In one embodiment of the present invention, the silicon-containing polymer is silicone, such as medical-grade silicone, which is recognized in the oral cavity field in China. Silicone materials are particularly soft and comfortable to apply to the user's gums and other oral tissues. They also have a certain degree of elastic deformation ability.

[0029] As shown in FIGS. 2 and 3 , the first orthodontic appliance 1 includes a first mounting portion 11 that contacts at least some of the teeth. The first mounting portion 11 is arranged parallel to the occlusal or horizontal plane and contacts the maxillofacial surfaces of some of the teeth. The lingual edge of the first mounting portion 11 extends toward the gums to form a first inner wall 12 located on the lingual side of the dental arch. Specifically, it extends 1 to 3 mm in the maxillary and mandibular directions, respectively, to cover the lingual surfaces of the maxillary and mandibular teeth and some of the gum areas. The labio-buccal edge of the first mounting portion 11 extends toward the gums to form a first outer wall 13. Similarly, the second outer wall 23 extends 1 to 9 mm in the maxillary and mandibular directions, respectively, to cover the labial surfaces of the maxillary and mandibular teeth and some of the gum areas. The first outer wall 13 blocks contact between the labio-buccal muscles and the dentition, thereby eliminating the influence of muscles on tooth alignment during the orthodontic process. The first outer wall 13, the first mounting portion 11 and the first inner wall 12 surround and form a first upper tray 14 that defines the upper dental arch and a first lower tray 15 that defines the lower dental arch, and the anterior tooth region of the first upper tray 14 and the anterior tooth region of the first lower tray 15 have a first distance L1 of the first stage in the sagittal direction relative to the treatment plan.

[0030] The shape of the second orthodontic appliance 2 in the orthodontic system is similar to that of the first orthodontic appliance 1. Specifically, the second orthodontic appliance 2 includes a second mounting portion 21 that contacts at least some of the teeth. The second mounting portion 21 is arranged parallel to the occlusal plane or horizontal plane and contacts the maxillofacial surfaces of some of the teeth. The lingual edge of the second mounting portion 21 extends in the gum direction to form a second inner wall 22 located on the lingual side of the dental arch. Specifically, it extends 1 to 3 mm in both the maxillary and mandibular directions to cover the lingual surfaces of the maxillary and mandibular teeth and some of the gum area. The labio-buccal edge of the second mounting portion 21 extends toward the gums to form a second outer wall 23. Similarly, the second outer wall 23 extends 1 to 9 mm toward the maxilla and mandible, respectively, to cover the labial surfaces of the maxillary and mandibular teeth and some of the gums. The second outer wall 23 blocks contact between the labio-buccal muscles and the dentition, thereby eliminating the influence of muscles on dental correction during the orthodontic process. The second outer wall 23, the second mounting portion 21, and the second inner wall 22 surround a second upper alveolar 24 that defines the upper dental arch and a second lower alveolar 25 that defines the lower dental arch. The anterior tooth region of the second upper alveolar 24 and the anterior tooth region of the second lower alveolar 25 are spaced apart in the sagittal direction by a second distance L2 for the second stage of the treatment plan. The first distance L1 is different from the second distance L2.

[0031] The book Clinical Orthodontic Treatment Based on Respiratory and Oral Muscle Function by Kondo Etsuko, translated by Shira Yuxing, Yang Li, and Zhao Hongju, states that "regardless of how effectively any orthodontic appliance can align the teeth, the stability of the final position of the teeth depends on the mechanical balance between multiple functions such as the oral-maxillary system and the respiratory system." Therefore, the orthodontic system in this application takes the condition of the muscles of the mouth as one of the reference elements when treating problems with tooth alignment or malocclusion using orthodontic appliances, and by using the outer wall structure of the orthodontic appliance to block contact between the labio-buccal muscles and the dentition, it eliminates the influence of the muscles of the mouth on correction and makes correction more accurate and reliable.

[0032] In some embodiments, as shown in Figure 4, the height H1 of the first outer wall 13 / second outer wall 23 in the anterior tooth region is 19mm to 26mm, and the height H2 in the posterior tooth region is 8mm to 13mm, as viewed vertically upward. This allows the orthodontic appliance to adapt to the situation in the patient's mouth during the wearing process, for example, to match different sizes of dental arches. Furthermore, the size of the orthodontic appliances used at different stages can be changed according to orthodontic needs, improving the accuracy of orthodontic treatment.

[0033] In some embodiments, the correction plan is divided into multiple correction stages, allowing for gradual adjustment of the sagittal relationship between the upper and lower jaws. For example, if the second stage corresponding to the second orthodontic appliance 2 is the next stage after the first stage corresponding to the first orthodontic appliance 1, the second distance L2 is smaller than the first distance L1 and is closer to the correction target than the first distance L1.

[0034] In some embodiments, as shown in Fig. 3, the first distance L1 is 3mm to 5mm, and the second distance L2 is 1mm to 3mm. For example, the orthodontic system for oral treatment includes three orthodontic appliances, and the sagittal distances between the anterior tooth regions of the upper alveoli and the anterior tooth regions of the lower alveoli of the three orthodontic appliances are 1mm, 3mm, and 5mm, respectively. The first orthodontic appliance 1 and the second orthodontic appliance 2 are any two of the three orthodontic appliances.

[0035] In another embodiment, when the first and second stages are adjacent stages of the treatment plan, the difference between the first distance and the second distance is 1 mm to 5 mm. Preferably, the difference between the first distance and the second distance is 2 mm or 3 mm. Also, the transition from the first stage to the second stage can be understood as the maxillary dentition or the mandibular dentition moving alone, or the maxillary dentition moving together with the mandibular dentition.

[0036] In some embodiments, the orthodontic system for oral treatment can be used to treat cases of deep bite or crossbite. When the orthodontic system is used to treat cases of deep bite, as shown in FIG. 2 , the relative arrangement relationship in the sagittal direction between the first upper cistern 14 and the first lower cistern 15 matches the relative positional relationship in the sagittal direction between the second upper cistern 24 and the second lower cistern 25. Specifically, the anterior region of the first upper cistern 14 is closer to the labial side than the anterior region of the first lower cistern 15, and the anterior region of the second upper cistern 24 is closer to the labial side than the anterior region of the second lower cistern 25. That is, the anterior region of the first lower cistern 15 is closer to the tongue than the anterior region of the first upper cistern 14, and the anterior region of the second lower cistern 25 is closer to the tongue than the anterior region of the second upper cistern 24. The amount of coverage of the patient by the first orthodontic appliance 1 and the second orthodontic appliance 2 in the orthodontic system is gradually reduced to achieve an accurate coverage relationship.

[0037] When the orthodontic system is used to treat an overbite case, as shown in FIG. 5, the relative arrangement relationship in the sagittal direction between the first upper and lower cisterns 14 and 15 is the same as the relative positional relationship in the sagittal direction between the second upper and lower cisterns 24 and 25. For example, the anterior tooth region of the first lower cistern 15 is closer to the lip side than the anterior tooth region of the first upper cistern 14, and the anterior tooth region of the second lower cistern 25 is closer to the lip side than the anterior tooth region of the second upper cistern 24. In other words, the anterior tooth region of the first upper cistern 14 is closer to the tongue than the anterior tooth region of the first lower cistern 15, and the anterior tooth region of the second upper cistern 24 is closer to the tongue than the anterior tooth region of the second lower cistern 25. Alternatively, as shown in FIG. 6, the relative arrangement relationship between the first upper cistern 14 and the first lower cistern 15 in the sagittal direction does not match the relative positional relationship between the second upper cistern 24 and the second lower cistern 25 in the sagittal direction, and an accurate covering relationship can be achieved for the patient by the first orthodontic appliance 1 and the second orthodontic appliance 2. For example, the anterior tooth region of the first lower cistern 15 is closer to the lip side than the anterior tooth region of the first upper cistern 14, i.e., the first lower cistern 15 is located anterior to the first upper cistern 14, and the anterior tooth region of the second upper cistern 24 is closer to the lip side than the anterior tooth region of the second lower cistern 25, i.e., the second upper cistern 24 is located anterior to the second lower cistern 25. When treating a patient with an overbite in this way, the second orthodontic appliance 2 may be the last orthodontic appliance in the oral treatment orthodontic system, and the target position of the second stage is also the final target position of the final correction, and the second orthodontic appliance 2 provides an accurate covering relationship.

[0038] In some embodiments, as shown in Figures 7 and 8, the first orthodontic appliance 1 or the second orthodontic appliance 2 is further provided with a power ridge 3 that prevents some teeth in the anterior tooth region from rotating toward the labial and lingual sides. For example, a power ridge 3 is provided on the inner surface of the first inner wall 12 and / or the inner surface of the first outer wall 13. A power ridge 3 is provided on the inner surface of the second inner wall 22 and / or the inner surface of the second outer wall 23. The power ridge 3 is formed to protrude from the inner surface in the tooth direction, and the protruding height of the power ridge 3 in the vertical direction is 0.5 mm or less.

[0039] In some embodiments, the power ridge 3 is provided adjacent the incisal edge of the tooth in the anterior region, as shown in Figures 7 and 8. One surface of the trough drives the tooth to move in the sagittal direction, and the other surface of the trough, adjacent the incisal edge of the tooth, projects toward the tooth, forming a power ridge 3 that prevents undesired labial and lingual tipping of the tooth during movement.

[0040] For example, in a case where a deep bite is corrected using the first orthodontic appliance 1, as shown in Figures 9 and 10, the anterior tooth region of the first lower cistern 15 of the first orthodontic appliance 1 is closer to the tongue than the anterior tooth region of the first upper cistern 14. The inner surface of the first outer wall 13 of the first upper cistern 14 applies a force F1 to move lingually to the teeth 100 in the maxillary anterior tooth region, which tends to cause the teeth to rotate lingually at their incisal edges. Therefore, a power ridge 3 is provided on the inner surface of the first inner wall 12 located in the first upper cistern 14 portion. The inner surface of the first inner wall 12 of the first lower cistern 15 applies a force F2 to move labially to the teeth 200 in the mandibular anterior tooth region, which tends to cause the teeth to rotate labially at their incisal edges. Therefore, a power ridge 3 is provided on the inner surface of the first outer wall 13 located in the first lower cistern 15 portion.

[0041] Also, for example, in a case where an overbite is corrected using the first orthodontic appliance 1, the patient's lower front teeth are positioned in front of the upper front teeth, a condition generally referred to as mandibular prognathism, and it is necessary to retract the lower front teeth and / or retract the upper front teeth. Therefore, in the above situation, as shown in Figures 11 and 12, the front tooth region of the first upper alveolar 14 of the first orthodontic appliance 1 is closer to the tongue than the front tooth region of the first lower alveolar 15. The inner surface of the first inner wall 12 of the first upper cistern 14 applies a force F3 to the teeth 100 in the maxillary anterior region to move them in the labially direction, which makes the teeth prone to rotate in the labially direction when in the incisal edge position, so a power ridge 3 is provided on the inner surface of the first outer wall 13 located in the first upper cistern 14 portion, and the inner surface of the first outer wall 13 of the first lower cistern 15 applies a force F4 to the teeth 200 in the mandibular anterior region to move them in the lingual direction, which makes the teeth prone to rotate in the lingual direction when in the incisal edge position, so a power ridge 3 is provided on the inner surface of the first inner wall 12 located in the first lower cistern 15 portion.

[0042] In some embodiments, as shown in Figures 7 and 8, the power ridges 3 may be provided continuously or discontinuously in the anterior tooth region. When the power ridges 3 are provided continuously in the anterior tooth region, the power ridges 3 cover at least four teeth in a row along the curve of the dental arch. Alternatively, the power ridges 3 cover a maximum of three teeth spaced apart, and at least two teeth. Alternatively, the power ridges 3 are provided along the mesiodistal direction of teeth where teeth with labially and lingually inclinations tend to appear.

[0043] In some embodiments, the vertically upward height of the first mounting portion 11 in the anterior tooth region is the same as the vertically upward height of the second mounting portion 21 in the anterior tooth region. The vertically upward heights of the first mounting portion 11 and the second mounting portion 21 in the anterior tooth region are the target covering relationship in the orthodontic plan, and by matching the vertically upward heights of the mounting portions of each orthodontic appliance in the orthodontic system in the anterior tooth region, the teeth in the maxillary and / or mandibular anterior tooth region can be gradually lowered to achieve the target covering relationship.

[0044] In some embodiments, as shown in Figure 13, in the tooth arrangement method for the current orthodontic stage, the height of the mounting portion of the orthodontic appliance in the posterior tooth region compensates for the gap X between the surface of the mounting portion in the posterior tooth region and the corresponding tooth. Also, as the orthodontic process progresses, the vertical upward height of the mounting portion of the orthodontic appliance in the posterior tooth region gradually decreases, and the Spee curve gradually flattens, thereby preventing the problem of posterior open bite caused by premature contact of the anterior teeth. In this way, when the anterior teeth are retracted during the orthodontic process, the lower anterior teeth do not contact the upper anterior teeth prematurely. The occlusal relationship during the orthodontic process can be gradually adjusted.

[0045] For example, as shown in FIGS. 14 and 15 , in the first stage of the treatment plan, the vertically upward height of the first mounting portion 11 in the posterior tooth region compensates for the gap X between the surface of the first mounting portion 11 in the posterior tooth region and the tooth at the corresponding position. In the second stage of the treatment plan, the vertically upward height of the second mounting portion 21 in the posterior tooth region compensates for the gap X between the surface of the second mounting portion 21 in the posterior tooth region and the tooth at the corresponding position. The height X1 of the first mounting portion 11 in the posterior tooth region is greater than the height X1 of the second mounting portion 21 in the posterior tooth region. The height X1 of the first mounting portion 11 in the posterior tooth region is 2 mm to 15 mm, and the height X2 of the second mounting portion 21 in the posterior tooth region is 2 mm to 6 mm.

[0046] In some embodiments, as shown in FIGS. 16 to 19, a jaw pad 4 is provided on the surface of the mounting part of the orthodontic appliance, and is removably connected to the mounting part by adjusting the vertical occlusal relationship between the upper and lower jaws. The removably connected jaw pad 4 is an engagement that limits at least two degrees of freedom, so that after the jaw pad 4 is attached, it is stably held on the mounting part and does not move or fall off during use.

[0047] The height of the jaw pad 4 compensates for the gap between the surface of the mounting portion in the posterior tooth region and the corresponding tooth. The jaw pad 4 is arranged on the mounting portion along the curve of the dental arch and can cover one or more teeth in the posterior tooth region. The compensation for the gap between the surface of the mounting portion in the posterior tooth region and the corresponding tooth mainly includes the following situations: In the first situation, the jaw pad 4 contacts only the occlusal surface of the corresponding tooth and does not apply any clinical orthodontic force. In this situation, the height of the jaw pad 4 designed for this tooth position is equal to the gap formed when the current tooth is placed in the posterior tooth region. In the second situation, the jaw pad 4 applies a clinical orthodontic force / pressure to the corresponding tooth. For example, in this situation, the height of the jaw pad 4 designed for this tooth position is greater than the gap formed when the current tooth is placed in the posterior tooth region so that the jaw pad 4 can apply an orthodontic force toward the gums after contacting the tooth.

[0048] In some embodiments, the jaw pad 4 is arranged continuously along the curve direction of the dental arch, and the advantage of the jaw pad 4 being arranged continuously is that the flattening of the curve of Spee can be gradually achieved by adjusting the height of the jaw pad 4 in different orthodontic processes.

[0049] In some embodiments, when the chin pad 4 is provided continuously along the dental arch curve in the posterior tooth region, the height of the chin pad 4 may gradually decrease from one end adjacent to the anterior tooth region to one end away from the anterior tooth region. Alternatively, the height of the chin pad 4 may gradually increase from one end adjacent to the anterior tooth region to one end away from the anterior tooth region. The height of the chin pad 4, specifically, the height of the chin pad 4 in the vertical direction, can be set between 0 and 15 mm.

[0050] In another embodiment, the jaw pads 4 are provided at intervals along the curve of the dental arch. The advantage of providing the jaw pads 4 continuously is that when an individual tooth requires pressure, the jaw pad 4 is attached to the position of the mounting part corresponding to that tooth, or when an individual tooth requires extension, the jaw pad 4 is attached to the position of the mounting part corresponding to the tooth adjacent to that tooth, thereby providing the tooth requiring extension space. By providing the jaw pads 4 at intervals, it is possible to accurately correct a single tooth and flexibly replace the jaw pads 4 of the required height for different correction stages.

[0051] In some embodiments, a jaw pad is provided on both the surface of the first mounting portion 11 of the first orthodontic appliance 1 and the surface of the second mounting portion 21 of the second orthodontic appliance 2. A first jaw pad for adjusting the occlusal relationship between the upper and lower jaws in the vertical direction is provided on the surface of the first mounting portion 11 adjacent to the maxillofacial surfaces of the teeth, and a second jaw pad for adjusting the occlusal relationship between the upper and lower jaws in the vertical direction is provided on the surface of the second mounting portion 21 adjacent to the maxillofacial surfaces of the teeth.

[0052] In some embodiments, the height of the first chin pad is greater than the height of the second chin pad.

[0053] In some embodiments, the first rest portion is removably connected to the first chin pad and the second rest portion is removably connected to the second chin pad.

[0054] In some embodiments, the first jaw pad and / or the second jaw pad are provided continuously along the curve of the dental arch.

[0055] In some embodiments, the first jaw pad and / or the second jaw pad are spaced apart along the curvature of the dental arch.

[0056] In another embodiment, as shown in Fig. 20, a housing 5 and a jaw pad 4 housed in the housing 5 are provided in the rear teeth region of the mounting part of the orthodontic appliance. The housing 5 is removably connected to the jaw pad 4, and the shape of the jaw pad 4 and the shape of the housing 5 match each other. The thickness of the jaw pad 4 may be 1 mm, 2 mm, 3 mm, or 5 mm, and the vertical upward height in the rear teeth region of the mounting part is adjusted.

[0057] The present invention further discloses a method for producing the orthodontic system for oral treatment, as shown in FIG.

[0058] In step 101, the upper and lower jaw covering relationship in the first stage and the upper and lower jaw covering relationship in the second stage are obtained based on the orthodontic plan. The upper and lower jaw covering relationship in the first stage is a first distance between the upper and lower jaw anterior teeth in the sagittal direction, and the upper and lower jaw covering relationship in the second stage is a second distance between the upper and lower jaw anterior teeth in the sagittal direction.

[0059] In step 102, the geometric shapes of the first orthodontic appliance and the second orthodontic appliance are determined. The geometric shape of the first orthodontic appliance includes a first upper orthodontic socket for accommodating at least the maxillary dentition and a first lower orthodontic socket for accommodating the mandibular dentition, and the distance between the first upper orthodontic socket and the first lower orthodontic socket in the sagittal direction is equal to the first distance. The geometric shape of the second orthodontic appliance includes a second upper orthodontic socket for accommodating at least the maxillary dentition and a second lower orthodontic socket for accommodating the mandibular dentition, and the distance between the second upper orthodontic socket and the second lower orthodontic socket in the sagittal direction is equal to the second distance, and the first distance is different from the second distance. A standardized orthodontic appliance model can be provided in the system, and an orthodontic model for the corresponding orthodontic stage can be generated based on the different cover relationships obtained for the corresponding orthodontic stage. Alternatively, a digitized orthodontic appliance model for the corresponding orthodontic stage can be directly generated based on the dentition arrangement status of each orthodontic stage. This means that there are no restrictions on the method or route for obtaining the geometric shapes of the first orthodontic appliance and / or the second orthodontic appliance.

[0060] In step 103, an orthodontic system for oral treatment is manufactured. Based on the geometric shapes of the first and second orthodontic appliances, the first and second orthodontic appliances can be directly obtained by additive manufacturing. Additive manufacturing, also known as 3D printing, is a manufacturing technology that combines computer-aided design, material processing, and molding technologies to produce physical objects by depositing specialized metallic materials, non-metallic materials, and biomedical materials layer by layer using methods such as extrusion, sintering, melting, photocuring, and jetting based on a digital model file using software and a numerical control system.

[0061] In step 103, the orthodontic system for oral treatment can also be manufactured by injection molding. For example, a mold is manufactured based on the geometric shapes of the first orthodontic appliance and the second orthodontic appliance, and then a material having thermoplastic properties is used to maintain fluidity at high temperatures, preferably at a high temperature of 160°C, and the fluidized silicone material is injected into the mold to form the first orthodontic appliance and the second orthodontic appliance.

[0062] Note that each module according to this embodiment is a logical module, and in actual application, one logical unit may be one physical unit, a part of one physical unit, or may be realized by a combination of multiple physical units. Furthermore, in order to emphasize the novel aspects of this invention, this embodiment does not introduce units that are less relevant to the means for solving the technical problem according to the present invention, but this embodiment does not imply the absence of other units.

[0063] As shown in FIG. 22, one embodiment of the present invention includes at least one processor 401; and a memory 402 communicatively connected to at least one processor 401.

[0064] The memory 402 stores instructions executable by at least one of the processors 401, and the instructions are executed by the at least one of the processors 401 so that the at least one of the processors 401 can perform a method for generating an orthodontic system for oral treatment.

[0065] The memory and the processor are connected by a bus system, which may include any number of interconnected buses and bridges, connecting various types of circuits between one or more processors and the memory. The bus may also connect various other circuits, such as peripherals, regulators, and power management circuits, all of which are well known in the art and will not be described here. A bus interface provides an interface between the bus and a transceiver. The transceiver may be a single component or multiple components, such as multiple receivers and transmitters, and is provided as a unit that communicates with various types of other devices over a transmission medium. Data processed by the processor is transmitted over a wireless medium by an antenna, which receives data and transmits it to the processor.

[0066] The processor is responsible for bus management and general processing, and may also provide a variety of functions including timing, peripheral interfaces, voltage regulation, power management, and other control functions. Memory may store data used by the processor when performing operations.

[0067] One embodiment of the present invention relates to a computer-readable storage medium having stored thereon a computer program which, when executed by a processor, implements the above-described method embodiments.
