Description

TECHNICAL FIELD

[0001] The present invention relates to a manufacturing method of a tooth arrangement correction dental brace, in particular to a manufacturing method of a tooth arrangement correction dental brace which can help tooth arrangement, shape of alveolar bone, and correct misaligned and misplaced teeth. BACKGROUND

[0002] According to the data of the World Health Organization, seven out of ten people in the world have different degrees of problems such as malocclusion, malocclusion, crowded teeth, interdental gap, exposed teeth, scoop, deep bite, open bite, etc. In addition to causing aesthetic problems, these conditions can also cause chewing dysfunction, tooth decay, and even temporomandibular joint disorder, periodontal disease, speech learning disorder, and hinder the normal development of the jaw. There are many reasons for malocclusion and malocclusion, most of which are due to congenital genetic factors such as anterior maxillary protrusion, posterior mandibular shrinkage, congenital tooth absence, and supernumerary teeth. Regardless of the cause, malocclusion or malocclusion can be treated through dental orthodontic treatment to improve oral health, function, and aesthetics.

[0003] Please refer to Figure 1 , Figure 1 The use of a conventional metal bracket corrector is shown. As shown in Figure 1 A metal bracket corrector 8 is used to be placed on the lip 96 side of the misaligned teeth 95 of the dental patient. In a few clinical cases, the metal bracket corrector 8 is installed on the tongue side, but based on the ease of cleaning, the ease of installation, and the overall cost, the metal bracket corrector 8 is installed on the lip 96 side, which is the most common choice for correction. Usually, the metal bracket corrector 8 adheres to multiple correction blocks 82 through a metal wire 81 (usually steel wire), and adheres multiple correction blocks 82 to multiple misaligned teeth 95 of the dental patient; then, the mechanical force of the metal wire 81 is used to forcibly twist and adjust the misaligned teeth 95, so that the misaligned teeth 95 are gradually adjusted and moved to the correct tooth position in three-dimensional space to achieve the technical effects of "tooth correction", "tooth shaping", and "tooth arrangement correction".

[0004] However, the above-mentioned conventional metal bracket corrector 8 has errors in mechanical force calculation and control force during installation, which leads to a series of control problems such as the misaligned teeth 95 being adjusted beyond the correct tooth slot position when the twisting / moving force of the metal wire 81 is too strong, the misaligned teeth 95 being displaced insufficiently and the correction period being too long when the twisting / moving force of the metal wire 81 is too weak. In addition, Figure 1The metal bracket corrector 8 makes it inconvenient for the dental correction patient to clean, and increases the probability of dental caries and periodontal disease. Of course, the metal bracket corrector 8 method limits the possibility of correction for children.

[0005] Therefore, how to eliminate the lack of metal wire 81 correction control, so that the dental patient can still maintain normal tooth brushing and oral cleaning during the tooth correction period, and make the tooth correction suitable for patients of different age groups such as adults and children, is the goal of those skilled in the art. SUMMARY

[0006] The main purpose of the present application is to eliminate the lack of metal wire correction control, overcome the displacement and angle control problems of traditional metal bracket correctors, and achieve precise displacement and angle correction control.

[0007] Another purpose of the present application is to provide a phased correction mouthpiece to improve and treat the problem of malocclusion or misaligned teeth, or to use the biological changes of the jaw correction tissue to achieve alveolar bone shaping and modification, and even to correct the problem of excessive or insufficient development of the dental arch to help arrange the teeth, and at the same time, the dental patient can still maintain normal tooth brushing and oral cleaning during the tooth correction period.

[0008] Still another purpose of the present application is to make the tooth correction, tooth shaping, tooth alignment correction, and bite correction suitable for patients of different age groups such as adults and children, and achieve bite adjustment and correction, so that the first molar of the dental patient is induced to erupt, or gradually displaced to the Class I tooth position relationship of Angle's Classification, and the upper and lower jaw bones are gradually displaced to the corresponding relationship of Centric Relation (CR), to improve the stability of the upper and lower jaw bite.

[0009] Still another purpose of the present application is to avoid respiratory obstruction, reduce or eliminate the "mouth breathing" condition caused by snoring and low tongue position, and make the sleep apnea patients or severe snoring patients perform "breathing training" to improve their snoring symptoms, eliminate the sound and frequency of snoring, and improve their sleep quality.

[0010] Still another purpose of the present application is to align the upper and lower jaw teeth of the dental patient with each other, and satisfy the optimal occlusal cusp relationship, so that the occlusal force is evenly distributed to more occlusal contact surfaces, preventing excessive local occlusal pressure at a single point, and making the condyle and disc of the temporomandibular joint in the most harmonious position.

[0011] To solve the above and other problems, the present application provides a manufacturing method of a tooth alignment brace, for manufacturing a tooth alignment brace, the manufacturing method comprising the following steps: step A01: obtaining a tooth position configuration map of upper jaw teeth and lower jaw teeth of a dental patient and digital 3D structure information thereof; step A02: reading the digital 3D structure information by a dental software and displaying the tooth position configuration map of the upper jaw teeth and the lower jaw teeth; step A03: identifying and labeling fossa concaves of the upper jaw teeth and cuspid teeth of the lower jaw teeth; step A04: connecting the fossa concaves of the upper jaw teeth into an upper occlusal line and displaying the upper occlusal line; step A05: connecting the cuspid teeth of the lower jaw teeth into a lower occlusal line and displaying the lower occlusal line; step A06: superimposing and fitting to form a correction arc line based on the upper occlusal line and the lower occlusal line; step A07: forming a plurality of upper jaw correction slots and a plurality of lower jaw correction slots according to the correction arc line; step A08: forming an upper jaw corresponding part of the tooth alignment brace according to the plurality of upper jaw correction slots and forming a lower jaw corresponding part of the tooth alignment brace according to the plurality of lower jaw correction slots.

[0014] The tooth alignment brace as described above, wherein after step A05, the positions or angles of individual teeth are adjusted according to the lower occlusal line.

[0015] The tooth alignment brace as described above, wherein after step A05, the line shape of the lower occlusal line is adjusted as a vector towards the center point of the incisors.

[0016] The tooth alignment brace as described above, wherein after step A06, the positions or angles of individual teeth are adjusted according to the correction arc line.

[0017] The tooth alignment brace as described above, wherein after step A06, the line shape of the correction arc line is adjusted as a vector towards the center point of the incisors.

[0018] The tooth alignment brace as described above, wherein the size of the correction arc line is between the upper occlusal line and the lower occlusal line; or the positions of individual tooth positions of the correction arc line are between individual tooth positions of the upper occlusal line and individual tooth positions of the lower occlusal line.

[0020] The tooth alignment brace as described above, wherein step A09 is further included to output the upper jaw counterpart and the lower jaw counterpart and combine them to obtain the tooth alignment brace.

[0021] Therefore, the tooth alignment brace and the manufacturing method thereof can eliminate the shortcomings of wire control, overcome the problems of correction displacement and correction angle control of traditional metal bracket correctors, achieve precise displacement and precise angle correction control, and achieve alveolar bone shaping and modification by using the biological changes of the jaw correction. The tooth alignment brace can also help correct the problems of overdevelopment and underdevelopment of the dental arch to help arrange the teeth. The tooth alignment brace can also allow the dental patients to maintain normal tooth brushing and oral cleaning during the tooth correction period. In addition, the tooth alignment brace can also adjust and correct the occlusion of the dental patients, induce the eruption of the first molar, gradually adjust the displacement of the first molar to the Class I tooth position relationship of Angle's Classification, and gradually displace the upper and lower jaw bones to the corresponding relationship of the Centric Relation (CR) to improve the stability of the upper and lower jaw occlusion. Therefore, the tooth alignment brace has great potential for clinical application and commercialization.

DETAILED DESCRIPTION

[0043] Orthodontic treatment is a very special oral treatment, which aims to achieve the technical effect of "tooth correction", "tooth shaping", and "tooth row correction" through dental treatment means, so that the upper and lower jaw tooth rows of dental patients can have beautiful, neat, and aesthetic dental arch profiles. In order to achieve the above functions, the present application hopes to achieve the technical effect of tooth correction and tooth shaping by manufacturing a tooth row correction kit. Please refer to Figure 2 , Figure 2 The manufacturing and use stage schematic diagram of the tooth row correction kit is shown. As Figure 2 shown, a first order correction dental appliance 10 of a tooth row correction kit is manufactured (step X101), the dental patient is treated with the first order correction dental appliance 10 (step X102), and then a second order correction dental appliance 20 of a tooth row correction kit is manufactured based on the results of the first order correction treatment (step X103), and the dental patient is treated with the second order correction dental appliance 20 (step X104).

[0044] Among them, please refer to Figure 3 , Figure 3 The manufacturing method schematic diagram of the first order correction dental appliance is shown. Here, the step X101 can be further expanded and subdivided intoFigure 3 Steps 11 to 17 are shown; as Figure 3 As shown, firstly, a dental anatomy diagram of a dental patient can be obtained using instruments such as computed tomography (CT), X-ray, MRI, or ultrasound, or through methods such as intraoral scanning or dental impressions (step 11). This dental anatomy diagram includes, but is not limited to, digital format files conforming to the Digital Imaging and Communications in Medicine (DICOM) protocol. Please refer to [further details omitted]. Figure 4 By using a computer 71 (including but not limited to hardware such as a computer, mobile phone, or server calculator) or dental software 72 to read and obtain the aforementioned dental structure diagram, the 3D spatial and structural visualization features of the dental arch, dentition 97, and each tooth's arrangement, orientation, direction, and contour can be obtained "before correction." Next, from the computer 71 or dental software 72, a buccal direction BS (Toward Buccal-Side Direction, i.e., the direction "pointing" to the cheeks on both sides of the dentition 97) is defined for the dental patient's dental arch and dentition 97 before correction; please also refer to... Figure 5A ,like Figure 5A As shown, in the buccal direction BS pointing towards both cheeks, a first expansion distance d1 is set with the position of the first molar 93 of the dental patient as a reference. Figure 3 Step 12), then based on the first molar 93, a first-stage anchoring groove C17 is set by displacing the first expansion distance d1 in the direction BS toward the cheek side. Figure 3Step 13). Here, the first-order anchoring slot C17 is the spatial position of the first molar 93 of the dental patient after it is expected to be displaced, and the first-order anchoring slot C17 conforms to Class I occlusion in Angle's Classification. Here, Angle's Classification classifies occlusion into three categories based on the anterior-posterior relationship of the first molar 93 of the upper and lower dentition. Class I occlusion is Neutrocclusion, which presents a normal horizontal overbite, with the upper incisors biting approximately 1-3 mm in front of the lower incisors. Class II occlusion is Distocclusion, which presents the upper incisors biting too far in front of the lower incisors, resulting in excessive horizontal overjet, or compensatory retraction of the upper incisors crowns, resulting in skeletal protrusion. Class III occlusion is characterized by the lower incisors biting in front of the upper incisors, resulting in negative overjet or anterior crossbite, causing symptoms of mandibular protrusion (commonly known as "underbite") or maxillary retrusion.

[0045] Again, such as Figure 5B As shown, the remaining teeth (i.e., incisors 91, canines 92, and other molars 94, excluding the first molar 93) are positioned according to the position of the first-order anchoring groove C17, with a second expansion distance d2 in the buccal direction BS (see reference). Figure 3d2 is different for each tooth, in general, the dentist or dental technician can determine the expansion distance d2 according to the size of the patient's mouth or the future predictable growth space (e.g. children, future mouth expansion, larger mouth), in clinical practice, the second expansion distance d2 is usually less than or equal to 1.2 times the first expansion distance d1, and greater than 0.2 times the first expansion distance d1, that is: 0.2*d1≦d2≦1.2*d1. Specifically, if it is the incisors 91, the second expansion distance d2 of the incisors 91 is less than or equal to 0.4 times the first expansion distance d1, and greater than or equal to 0.2 times the first expansion distance d1, that is: 0.2*d1≦d2≦0.4*d1; if it is the canines 92, the second expansion distance d2 of the canines 92 is less than or equal to 0.8 times the first expansion distance d1, and greater than or equal to 0.4 times the first expansion distance d1, that is: 0.4*d1≦d2≦0.8*d1; if it is other molars 94, the second expansion distance d2 of the plurality of other molars 94 is less than or equal to 1.2 times the first expansion distance d1, and greater than or equal to 0.8 times the first expansion distance d1, that is: 0.8*d1≦d2≦1.2*d1. That is, the dentist or dental technician can determine the size of the second expansion distance d2 according to the type of tooth, and then arrange the plurality of first-order matching slots C18 to correspond to all the remaining teeth outside the first large molar 93 Figure 3 Step 15) of the method.

[0046] Next, as shown in Figure 5C , a plurality of first-order anchoring slots C17 and first-order matching slots C18 are formed on the first-order dental arch portion 11 to form a 3D digital stereoscopic structure of the first-order orthodontic aligner 10 Figure 3 Step 16) of the method; thus, the physical structure of the first-order orthodontic aligner 10 can be output and obtained by 3D printing technology Figure 3 Step 17) of the method, and the physical structure of the first-order orthodontic aligner 10 is as shown in Figure 6A , Figure 6B

[0047] Please refer to Figure 6A , Figure 6B , Figures 6A-6B illustrated as a perspective view and a top view of the first-order orthodontic aligner; at this time, the completed first-order orthodontic aligner 10, the main part is the first-order dental arch portion 11, and the first-order dental arch portion 11 has a plurality of first-order anchoring slots C17 and a plurality of first-order matching slots C18. At this time, as shown in Figure 7A , the patient can open his mouth, and the upper and lower dental arches and teeth 97 can be aligned with the first-order orthodontic aligner 10, and then, as shown in Figure 7B ​、 Figure 7C The dental patient closes his mouth and bites the first-stage aligner 10 with the upper and lower dental arches and dentition 97.

[0048] Please refer to Figures 5A-5C and Figure 8 , Figure 8 The first-stage aligner 10 is shown in a schematic view corresponding to the teeth of the dental patient. When the dental patient uses and bites the first-stage aligner 10, the first-stage anchoring slot C17 of the first-stage aligner 10 corresponds to the first molar 93 of the dental patient. Therefore, the first-stage anchoring slot C17 is arranged to be displaced by a first expansion distance dl in the buccal direction BS. In addition, the first-stage cooperating slots C18 correspond to the remaining teeth (i.e., the incisors 91, canines 92 and other molars 94 except the first molar 93) of the dental patient. Therefore, the first-stage cooperating slots C18 are arranged to be displaced by a second expansion distance d2 in the buccal direction BS based on the original positions of the remaining teeth. As described above, the first expansion distance dl is arranged and adjusted in step 12 of the method 10 to determine the position, orientation and angle of the first molar 93 corresponding to the first-stage dental arch portion 11. The second expansion distance d2 is arranged and adjusted in step 14 of the method 10 to determine the position, orientation and angle of the remaining teeth (i.e., the incisors 91, canines 92 and other molars 94 except the first molar 93) corresponding to the first-stage dental arch portion 11. In this way, the dentist or dental technician can plan the "desired displacement and rotation angle" of the upper and lower dental arches and dentition 97 in the first stage by using the first-stage aligner 10. Then, the dental patient wears the first-stage aligner 10 to displace and rotate each tooth of the dental arches and dentition 97 to achieve the purpose of the first-stage correction. In this case, the greater the first expansion distance dl and the second expansion distance d2, the greater the expected displacement of the teeth in this stage. Figure 3 Figure 3

[0049] Also, as shown in Figure 6A , the first-stage aligner 10 further comprises a first-stage tongue- contacting portion 12 arranged on the inner side of the first-stage dental arch portion 11. The first-stage tongue-contacting portion 12 further comprises a break or U-shaped slot-shaped sublingual support slot 13 arranged in the middle to accommodate the human tongue's sublingual frenulum (ankyloglossia, also known as tongue-tie). In this way, when the dental patient bites the first-stage aligner 10 and places his tongue above the first-stage tongue-contacting portion 12, the discomfort of the patient can be reduced and the willingness to use it can be increased. In addition, as shown in Figure 7C ​​As shown, the height of the first-stage tongue-blocking portion 12 gradually decreases in the opposite direction to the labial side (LS) (i.e., the palatal side (PS)). Thus, when a dental patient bites down on the first-stage orthodontic brace 10, placing their tongue 98 on the first-stage tongue-blocking portion 12, the height of the tongue 98 is raised, relaxing the throat muscles and opening the airway to prevent airway obstruction, reducing or eliminating snoring and "mouth breathing" caused by a low tongue position. Furthermore, through the design of the first-stage tongue-blocking portion 12, the first-stage orthodontic brace 10 of this invention can also allow patients with sleep apnea or severe snoring to perform "breathing training" to improve their snoring symptoms, eliminate the sound and frequency of snoring, and improve their sleep quality.

[0050] In addition, the execution Figure 3 Steps 11 to 17 will complete the process. Figure 2 Step X101 involves the fabrication of the first-stage orthodontic aligner 10. After the fabrication of the first-stage orthodontic aligner 10 is completed, as follows... Figure 2 As shown in step X102, the dental patient can undergo the first stage of orthodontic treatment using the first-stage orthodontic braces 10. The purpose of this first-stage orthodontic treatment in step X102 is that dental patients who generally require orthodontic treatment often have problems with narrow or insufficient dental arches. Therefore, before correcting the movement or rotation of individual teeth, the dental arch must be appropriately pulled towards the buccal sides (BS) to expand and increase its width. Then, the position of the teeth can be planned according to the size of the permanent teeth and the available space. In cases where there is insufficient space for tooth growth, the alveolar bone can be expanded, or bone growth can be inhibited in cases of excessive alveolar bone growth. This not only increases the space for each tooth and the space for rotation, but also makes the patient's chin contour more aesthetically pleasing. Furthermore, according to the clinical usage data of the applicant in this case, dental patients using the first-stage orthodontic braces 10 can achieve the goal of correction by moving individual teeth in the dental arch and dentition 97 at a rate of 1 mm per 2 to 6 weeks.

[0051] Please refer to the following at the same time. Figure 9 , Figure 10 , Figure 9 The diagram illustrates the manufacturing process of the second-stage orthodontic braces. Figure 10 The diagram illustrates the corresponding slots of the first-stage orthodontic aligner and the second-stage orthodontic aligner. Here, by... Figure 2 Step X103 is expanded and subdivided into Figure 9Steps 21 to 25 are shown below. First, a dental structure diagram of the patient's teeth after the "first-stage orthodontic treatment" is obtained (step 21). The method of obtaining this diagram is the same as the manufacturing method of the first-stage orthodontic braces 10, including but not limited to instruments such as CT, X-ray, MRI, or ultrasound, or methods such as intraoral scanning, dental impressions, etc. Next, a second-stage anchoring groove C27 is set according to the first-stage anchoring groove C17 (step 22), and multiple second-stage mating grooves C28 are adjusted and set according to multiple first-stage mating grooves C18 (step 23). In a further specific implementation, in step 23, the position of the second-stage mating slot C28 can be set by moving the position of the first-stage mating slot C18 by one-quarter to one-third of the tooth cross-sectional width, or by rotating the position of the first-stage mating slot C18 by an angle less than 30 degrees; that is, the position of the second-stage mating slot C28 in step 23 is set by finely adjusting the displacement or angle based on the first-stage mating slot C18. Therefore, as Figure 10 As shown, based on the first-stage anchoring slot C17 and the first-stage mating slot C18 from the first stage, the dentist or dental technician determines the "desired displacement and rotation angle" of each tooth in the "second-stage orthodontic treatment," and then adjusts and sets the tooth positions in the second stage. Next, the second-stage anchoring slot C27 and the second-stage mating slot C28 are formed on a second-stage dental arch 21, forming a 3D digital three-dimensional structure of a second-stage orthodontic brace 20 (step 24). Then, the physical structure of the second-stage orthodontic brace 20 can be output (step 25). Here, the second-stage anchoring slot C27 conforms to the Class I tooth position relationship of Angle's Classification. Furthermore, the forming and manufacturing of the 3D digital three-dimensional structure and physical structure of the second-stage orthodontic brace 20 in steps 24 and 25 are the same as in the aforementioned "first stage," and will not be described again.

[0052] In this way, when the second-stage orthodontic brace 20 is completed, its main body is the second-stage dental arch 21. The second-stage dental arch 21 has multiple second-stage anchoring slots C27 and multiple second-stage mating slots C28. The position of the second-stage anchoring slots C27 is the same as that of the aforementioned first-stage anchoring slots C17. The second-stage mating slots C28 move or rotate based on the aforementioned first-stage mating slots C18.

[0053] Next, the dental patient can wear the second-stage orthodontic braces 20 to begin the "second phase" of orthodontic treatment. Figure 2of the second stage anchoring groove C27, to achieve the desired occlusal adjustment and occlusal correction effect of the teeth arrangement 97, so that the first molar 93 gradually moves to the Class I occlusal position of Angle's Classification, and the upper and lower jaw bones move to the corresponding relationship of the centric relation (CR), so as to improve the stability of the upper and lower jaw occlusion. It is particularly pointed out that the centric occlusion (CO) relationship of the teeth is the position of the maximum occlusal surface of the upper and lower teeth; the centric relation (CR) relationship is the position of the joint head of the temporomandibular joint in the middle of the joint socket, which is the most stable position. Generally speaking, the ideal occlusal position is 0.5-1 mm different from the centric occlusion (CO) and the centric relation (CR). The teeth arrangement correction kit of the present application can adjust the teeth arrangement and the position of the teeth in stages for the dental patients with Class II and Class III malocclusion of Angle's Classification, so that the first molar 93 of the dental patient is gradually adjusted and corrected into the Class I occlusal position (i.e. the spatial position of the first anchoring groove C17 and the second anchoring groove C27). In this way, the first molar 93 of the dental patient can be guided and anchored in the Class I occlusal position, and the bones of the upper and lower jaws can be kept in the centric relation to maintain the health of the temporomandibular joint. Even if the dental patient is in the period of losing milk teeth and the initial eruption of permanent teeth, the correction kit of the present application can adjust the facial contour and the lower jaw contour during the teenage period, so that the teenagers have a more beautiful facial contour. In addition, for patients with muscle dysfunction, such as tongue piercing or reverse swallowing symptoms, the correction kit of the present application can also improve the problems of insufficient mastication function and lateral mastication through occlusal training. In addition, since the 1990s, scholars have found that bone-forming cells (osteoblasts) and bone-resorbing cells (osteoclasts) interact to affect the growth or contraction of the upper and lower jaw bones.When the dental patients use the tooth alignment kit of the present application, the mechanical bite of the upper and lower jaw teeth can stimulate the sensitive cells in the oral cavity, and the mechanical force of the bite can be converted into biological chemical nerve signals of the human body to activate and intensify the "bone-forming cells" or "bone-absorbing cells", thereby controlling the "bone growth" or "bone absorption" in a certain local part of the oral cavity. That is, the alveolar bone of the dental patients wearing the tooth alignment kit of the present application will have a corresponding reaction to the design profile of the first-stage orthodontic aligner 10 or the second-stage orthodontic aligner 20 to activate and intensify the bone-forming cells or bone-absorbing cells, thereby causing the alveolar bone to grow or shrink to achieve the purpose of alveolar bone shaping; thus, having the functions of jaw bone orthopedic correction and lower jaw shape adjustment. Therefore, by using the tissue change biology of tooth and jaw correction, the alveolar bone shaping, bone finishing, bone correction, and even the correction of overdevelopment of the dental arch or insufficient alveolar bone can be achieved to help the teeth to be arranged in the correct position.

[0054] Of course, the second-stage orthodontic aligner 20 also includes a second-stage tongue-ward position and a sublingual support groove 13 to enable the dental patients wearing the second-stage orthodontic aligner 20 to raise the height position of the tongue 98 to relax the muscles of the throat, thereby opening the airway to avoid airway obstruction, reduce or eliminate the "mouth breathing" condition caused by snoring and low tongue position, and also enable sleep apnea patients or severe snoring patients to perform "breathing training" to achieve the technical effects of improving the snoring symptoms of the patients, eliminating the sound and frequency of snoring.

[0055] Next, the dentist will decide whether the dental patients need to receive "the third stage" of correction according to the corrected condition of the dental patients, and if the third-stage correction is needed, the third-stage orthodontic aligner will be manufactured. Please refer to Figure 11 , Figure 11 The manufacturing method of the third-stage orthodontic aligner is shown in the schematic diagram. As Figure 11As shown, the tooth position configuration diagram of the dental patient after the second stage correction is obtained (step 31), a third stage anchoring slot position is set according to the second stage anchoring slot C27 (step 32), and a plurality of third stage cooperation slot positions are adjusted and set according to the plurality of second stage cooperation slot C28 (step 33), then the third stage anchoring slot and the third stage cooperation slot are formed on a third stage dental arch part to form a 3D digital stereoscopic structure of a third stage correction dental brace (step 34). Finally, the physical structure of the third stage correction dental brace is output (step 35). In this way, the manufactured third stage correction dental brace includes a third stage dental arch part, and a plurality of third stage anchoring slots and a plurality of third stage cooperation slots arranged on the third stage dental arch part, the position of the third stage anchoring slot is the same as the second stage anchoring slot C27; the third stage cooperation slot is moved or rotated based on the second stage cooperation slot C28, and the adjustment moving distance can be one fourth to one third of the tooth cross-sectional width, or the rotation angle is less than 30 degrees. Here, the third stage correction dental brace of the third stage is similar to the manufacturing method of the second stage correction dental brace 20 of the second stage, and is not described again. The purpose of the third stage correction is to supplement the second stage correction or later treatment, so that the effect of the tooth arrangement correction is greater, and the tooth arrangement profile of the dental patient is further adjusted.

[0056] In addition, as Figures 12A-12B , Figures 12A-12B The rear view and the perspective view of the upper jaw corresponding part and the lower jaw corresponding part corresponding to the upper jaw teeth and the lower jaw teeth are shown. The tooth arrangement correction kit of the present application can also be composed of an upper jaw corresponding part 50A and a lower jaw corresponding part 50B, that is, the upper jaw corresponding part 50A and the lower jaw corresponding part 50B are combined and pasted to form the first stage correction dental brace 10, the second stage correction dental brace 20 or the third stage correction dental brace. As Figures 12A-12BAs shown, the maxillary corresponding component 50A includes an upper support plate 51, an upper side guard plate 53, and multiple upper alveolar ridges 55. The multiple upper alveolar ridges 55, which are concave or groove-shaped, are arranged sequentially on the upper support plate 51 and can cooperate with the maxillary teeth 97A of a dental patient. The upper side guard plate 53 is adjacent to the upper alveolar ridges 55 in the labial direction LS and the buccal direction BS, and the upper side guard plate 53 is connected to the upper support plate 51. The mandibular corresponding component 50B includes a lower support plate 52, a lower side guard plate 54, and multiple lower alveolar ridges 56. The multiple lower alveolar ridges 56, which are concave or groove-shaped, are arranged sequentially on the lower support plate 52 and can cooperate with the lower teeth 97B of a dental patient. The lower guard plate 54 is adjacent to the lower alveolar position 56 in the labial direction LS and the buccal direction BS, and the lower guard plate 54 is connected to the lower support plate 52. In this way, the multiple upper alveolar positions 55 or lower alveolar positions 56 are the aforementioned first-stage anchoring groove C17, first-stage mating groove C18, second-stage anchoring groove C27, second-stage mating groove C28, third-stage anchoring groove, or third-stage mating groove.

[0057] like Figure 12A As shown, when a dental patient bites, the upper tooth 97A enters the upper alveolar space 55, and the lower tooth 97B enters the lower alveolar space 56. Therefore, the upper alveolar space 55 of the upper jaw correspondent 50A can guide the upper tooth 97A to move or rotate, thereby achieving the orthodontic effect of the upper tooth 97A. Similarly, the lower alveolar space 56 of the lower jaw correspondent 50B can guide the lower tooth 97B to move or rotate, thereby achieving the orthodontic effect of the lower tooth 97B. The upper alveolar ridge 55 includes a first corresponding point 551, and the lower alveolar ridge 56 includes a second corresponding point 561. The first corresponding point 551 of the upper alveolar ridge 55 can directly abut and align with the fossa of the upper tooth 97A, and the second corresponding point 561 of the lower alveolar ridge 56 can directly abut and align with the cusp 97D of the lower tooth 97B in the buccal direction BS. Therefore, after the aforementioned first, second, or third orthodontic treatment, the fossa 97C of the upper tooth 97A can be aligned with the cusp 97D of the lower tooth 97B in the buccal direction BS, thereby maximizing the occlusal contact area of ​​the upper tooth 97A and the lower tooth 97B, conforming to the optimal cusp-fossa occlusal relationship. This optimal upper and lower occlusal relationship is as follows: Figure 13As shown, the corrected maxillary teeth 97A and mandibular teeth 97B can satisfy the optimal cusp-fossa relationship, i.e. the fossa 97C of the maxillary tooth 97A is aligned and adjacent to the cusp 97D of the mandibular tooth 97B in the buccal direction BS, and the occlusal contact area of the upper and lower teeth is maximized. When the teeth of a person are occluded in the maximum intercusp-fossa relationship, the cusp 97D slope can distribute the occlusal force in multiple directions, thereby preventing excessive point pressure on the individual teeth involved. In this way, there is no interference or skewed contact in the functional occlusal contact; when eating, the mandibular teeth 97B can move normally in the normal occlusal contact state, and the maxillary teeth 97A and mandibular teeth 97B occlude in the harmonious position of the condyle and articular disc of the temporomandibular joint. Therefore, it is not easy to cause poor occlusal contact and thus temporomandibular joint disorder, and the probability of joint inflammation is reduced, and the muscles controlling the jaw movement become more relaxed and comfortable. Therefore, it is crucial to correct the maxillary teeth 97A and mandibular teeth 97B of the orthodontic patient to achieve the optimal cusp-fossa relationship of the upper and lower teeth.

[0058] Next, please refer to Figure 14 , Figure 14 The occlusal line alignment diagram of the maxillary teeth and mandibular teeth is shown. As Figure 14 shown, the fossa 97C of each maxillary tooth 97A is aligned and corresponds to the cusp 97D of each mandibular tooth 97B; the fossa 97C of the plurality of maxillary teeth 97A forms a curved arc maxillary occlusal line M1, and the cusp 97D of the plurality of mandibular teeth 97B also forms a curved arc mandibular occlusal line M2. It is particularly noted that since the fossa 97C is generally located at the center of the maxillary tooth 97A, the maxillary occlusal line M1 formed by connecting the fossa 97C is generally referred to as the maxillary central line. The maxillary occlusal line M1 and the mandibular occlusal line M2 correspond to each other, i.e. the optimal cusp-fossa relationship is achieved. That is, when designing the first-stage correction dental brace 10, the second-stage correction dental brace 20, the third-stage correction dental brace, or the maxillary counterpart and the mandibular counterpart, the spatial position and angle of the first-stage anchor slot C17, the first-stage fitting slot C18, the second-stage anchor slot C27, the second-stage fitting slot C28, the third-stage anchor slot, or the third-stage fitting slot can be adjusted in the dental software 72 to align and correspond to each other the maxillary tooth slot 55 and the mandibular tooth slot 56 to satisfy the optimal occlusal cusp-fossa relationship, so that the orthodontic patient can achieve the best dental correction effect.

[0059] As shown in Figure 12A , Figure 12B , the upper jaw counterpart 50A and the lower jaw counterpart 50B can be manufactured separately, and then the upper alveolar site 55 and the lower alveolar site 56 are respectively directed upward and downward, and the upper support plate 51 and the lower support plate 52 are combined and pasted. Please continue to refer to Figures 15A-15B , Figures 15A-15B , which shows the structure of the upper jaw counterpart and the lower jaw counterpart used in different stages of correction. As shown in Figures 15A-15B , the upper jaw counterpart 50A and the lower jaw counterpart 50B can be connected with a misalignment distance h1, h2. For example, in the first stage of correction, the upper jaw teeth 97A and the lower jaw teeth 97B of the dental patient are misaligned more seriously, so as shown in Figure 15A , the upper support plate 51 and the lower support plate 52 can be misaligned and pasted along the labial direction LS with a larger misalignment distance h1. When it comes to the second stage of correction, the misalignment degree of the upper jaw teeth 97A and the lower jaw teeth 97B of the dental patient has been reduced, so as shown in Figure 15B , the misalignment distance h2 of the pasted upper support plate 51 and the lower support plate 52 is smaller. That is, the designed upper jaw counterpart 50A and the lower jaw counterpart 50B can be used for multi-stage correction treatment, that is, manufactured into a first-stage correction mouthpiece 10, a second-stage correction mouthpiece 20 or a third-stage correction mouthpiece. In general clinical practice, the misalignment distance h1, h2 ranges from 0 to 15 mm.

[0060] In addition, in the clinical practice of tooth correction, the tooth alignment correction kit of the present application can achieve the displacement and correction of a single tooth, and can also implement the correction of multiple teeth. In the case of multiple teeth correction, the dental arch expansion of the tooth row 97 (i.e. the whole row of teeth) is usually performed first, and then the micro-radiation displacement or micro-radiation rotation of individual single teeth is performed. Then, when designing the positions of the upper alveolar site 55 and the lower alveolar site 56 in the dental software 72, the sequence should first arrange and set multiple upper alveolar sites 55 to make the upper jaw teeth 97A expand the arch or displace and rotate the teeth, and then adjust each lower alveolar site 56 according to the arranged upper alveolar sites 55, so that the individual lower jaw teeth 97B align and align the tooth tips 97D in the buccal direction BS with the concave 97C of the upper jaw teeth 97A, so as to achieve the correct occlusion tip and concave relationship.

[0061] In addition, in order to strengthen the correction effect of pushing the teeth, at least one tooth pushing protrusion 57 can be provided on the tooth alignment correction kit to speed up and increase the speed and amplitude of tooth correction. Please refer to Figures 16A-16B , Figures 16A-16BThe perspective view and sectional view of the tooth alignment kit of the present application with the tooth pushing protrusions are shown. As shown in Figure 16A , Figure 16B The tooth pushing protrusions 57 are arranged on the periphery of the upper tooth slot 55 and the lower tooth slot 56, and the specific position can be arranged on the inner side of the upper support plate 51 and / or the inner side of the lower support plate 52, that is, arranged on the periphery of the upper tooth slot 55, the lower tooth slot 56, the labial side direction LS, the buccal side direction BS, the palatal side direction BS, or the lingual side direction LgS. Figure 16B In the embodiment shown in

[0062] Please refer to Figures 17-18 , Figures 17-18 The other embodiment of the tooth alignment kit of the present application with the tooth pushing protrusions is shown. As shown in Figure 17 If the protruding teeth are only part of the teeth, the tooth pushing protrusions 57 can be arranged only in part of the inner side of the upper support plate 51, or only on the periphery of a few teeth, so that the tooth pushing protrusions 57 are used to push a few particularly serious protruding teeth; that is, the teeth without protruding teeth do not need to be arranged with the tooth pushing protrusions 57.

[0063] As shown in Figure 18 The lower jaw teeth 97B are shown to be excessively retracted, so the lower tooth pushing protrusions 57 are arranged on the lingual side direction LgS of the lower tooth slot 56, so that the tooth pushing protrusions 57 of the lower jaw corresponding part 50B can exert an outward (i.e. towards the labial side direction LS) pushing force on the retracted lower jaw teeth 97B, thereby increasing and strengthening the correction of the lower jaw teeth 97B and shortening the correction time.

[0064] The present application has other embodiments for manufacturing a tooth alignment kit in different ways. Please refer to Figure 19 , Figure 19 The flow chart of the manufacturing method of the tooth alignment kit of another embodiment of the present application is shown. As shown in Figure 19As shown, the manufacturing method of the present embodiment first obtains the tooth position configuration diagram of the upper jaw teeth 97A and lower jaw teeth 97B of a dental patient and the digitized 3D structure information thereof (step A01). The method for obtaining the same is as follows. Figure 20 As shown, the digitized 3D structure information of the upper jaw teeth 97A and lower jaw teeth 97B of the dental patient can be obtained by scanning a plaster dental mold 74 (obtained by molding the oral cavity of the dental patient) through a scanner 73, or directly scanning the oral cavity of the dental patient through the scanner 73. Then, as shown, Figure 21 As shown, the digitized 3D structure information of the upper jaw teeth 97A and lower jaw teeth 97B of the dental patient is read by the dental software 72, and the tooth position configuration diagram of the upper jaw teeth 97A and lower jaw teeth 97B is displayed (step A02). Then, the dental software 72 identifies and labels the multiple fossae 97C of the upper jaw teeth 97A and the multiple cusps 97D of the lower jaw teeth 97B (step A03); then, the multiple fossae 97C of the upper jaw teeth 97A are connected to form an upper occlusal line M1, and the display of the upper occlusal line M1 is shown (step A04); the multiple cusps 97D of the lower jaw teeth 97B are connected to form a lower occlusal line M2, and the display of the lower occlusal line M2 is shown (step A05). The display of the upper occlusal line M1 and lower occlusal line M2 can be as shown, Figure 22 、 Figure 23 As shown, the display of the upper occlusal line M1 and lower occlusal line M2 can be side-by-side comparison through folding, alignment, rotation, and the like, so that the dental technician or operator of the dental software 72 can know the severity of the occlusal deviation of the dental patient. Next, as shown, Figure 24 As shown, the upper occlusal line M1 and lower occlusal line M2 can be used as the basis to form a correction arc line M3 by superimposition and fitting (step A06), so that the size of the correction arc line M3 is between the upper occlusal line M1 and the lower occlusal line M2. For step A06, the coordinates of each point on the correction arc line M3 or the position of each tooth site is distributed at the position points between the upper occlusal line M1 and the lower occlusal line M2. As long as the proportion value of the correction arc line M3 approaching the lingual side direction LgS is adjusted (i.e., the vector pointing to the lingual side direction LgS is used as the reference to adjust the reduction or enlargement proportion value of the correction arc line M3), the coordinates of all points on the correction arc line M3 can be easily adjusted, so that the position of each tooth site on the correction arc line M3 is between the position of each tooth site on the upper occlusal line M1 and the position of each tooth site on the lower occlusal line M2. After the size and position of the correction arc line M3 are determined, as shown, Figure 25 According to the correction arc line M3, a plurality of cusp-fossa corresponding points 97K (all located on the correction arc line M3) can be formed. Here, as shown, Figure 25 As shown in the left half of the screen of the dental software 72, the plurality of cusp-fossa corresponding points 97K correspond to the fossae 97C of the upper jaw teeth 97A after the expected correction (see also Figure 13 、 Figure 14), thereby generating a plurality of upper jaw correction slots C41. As shown in Figure 25 The plurality of cusp-fossa corresponding points 97K correspond to the cusps 97D of the expected corrected lower jaw teeth 97B (see also Figure 13 、 Figure 14 ), thereby generating a plurality of lower jaw correction slots C42. That is, the cusp-fossa corresponding points 97K are the corresponding points of the individual upper jaw teeth 97A and lower jaw teeth 97B, and the purpose is to enable the upper jaw teeth 97A and lower jaw teeth 97B to be moved to the upper jaw correction slots C41 and lower jaw correction slots C42, so that the upper and lower dental arches reach the Maximal Intercuspal Position, and the Cusp to Fossa Relationship is optimal. After the upper jaw teeth 97A and lower jaw teeth 97B are moved to the positions of the cusp-fossa corresponding points 97K, the Class I occlusal relationship of Angle's Classification is achieved. Therefore, by the above-mentioned digital tooth alignment method, the dental arches of the patient are guided to the state of Centric Occlusion (CO), and the Cusp to Fossa Relationship of Maximum Intercuspation is achieved. Here, the upper jaw correction slots C41 are the expected positions of the upper jaw teeth 97A of the dental patient after correction, that is, after the upper jaw teeth 97A are corrected, the upper jaw teeth 97A are moved to the positions of the upper jaw correction slots C41. Similarly, the lower jaw correction slots C42 are the expected positions of the lower jaw teeth 97B of the dental patient after correction, that is, after the lower jaw teeth 97B are corrected, the lower jaw teeth 97B are moved to the positions of the lower jaw correction slots C42.

[0065] Accordingly, as shown in Figure 26 , the correction arcs M3 are used to form the plurality of upper jaw correction slots C41 and the plurality of lower jaw correction slots C42 (step A07), and then an upper jaw corresponding piece 50A is formed according to the plurality of upper jaw correction slots C41, and a lower jaw corresponding piece 50B is formed according to the plurality of lower jaw correction slots C42 (step A08); the dental software 72 forms the upper jaw corresponding piece 50A and the lower jaw corresponding piece 50B as shown in Figure 27 . Finally, as shown in Figure 28 、 Figure 29The upper jaw counterpart 50A and the lower jaw counterpart 50B are outputted from the dental software 72, which can be obtained by 3D printing or by plastic injection molding. In this way, the teeth alignment dental brace 40 can be worn in the oral cavity of the dental patient to guide the upper jaw teeth 97A and the lower jaw teeth 97B to move and rotate positions by the upper jaw correction slot C41 and the lower jaw correction slot C42, thereby achieving the effect of correction and treating the problems of malocclusion, malocclusion, and malocclusion (Malocclusion). It is very convenient.

[0066] In further embodiments, the positions or angles of individual teeth can be adjusted according to the upper occlusal line M1 after step A04 of the manufacturing method of the present embodiment, or the linearity of the upper occlusal line M1 is adjusted as a vector towards the center point of the incisors (to change the curvature of the subsequent correction arc M3, thereby shaping the face of the dental patient). Therefore, the dentist or dental technician can fine-tune the positions or angles of individual teeth. Similarly, the positions or angles of individual teeth can be adjusted according to the lower occlusal line M2 after step A05 of the manufacturing method of the present embodiment, or the linearity of the lower occlusal line M2 is adjusted as a vector towards the center point of the incisors. When the correction arc M3 is generated by the dental software 72 (after step A06), the positions or angles of individual teeth can be adjusted according to the correction arc M3, or the linearity of the correction arc M3 is adjusted as a vector towards the center point of the incisors.

[0067] By this way, the tooth alignment correction set or the tooth alignment correction mouthpiece 40 manufactured by the manufacturing method of the present application can be manufactured in different correction stages, set the tooth position for predetermined tooth movement or rotation, and allow the correction mouthpiece to be implemented in the oral cavity of the dental patient to correct the teeth in stages, improve and treat the problem of malocclusion or misaligned teeth, or use the tissue change biology of the orthodontic to achieve the shaping and finishing of the alveolar bone, and even correct the problem of overdevelopment or underdevelopment of the dental arch to help the teeth to be arranged in the correct position. In addition, the first-stage tongue-approaching part 12 and the second-stage tongue-approaching part 22 of the correction mouthpiece can improve the height position of the tongue 98 to avoid airway obstruction, reduce or eliminate the "mouth breathing" condition caused by snoring and low tongue position, and allow sleep apnea patients or severe snoring patients to perform "breathing training" to improve their snoring symptoms, eliminate the sound and frequency of snoring, and improve their sleep quality. Furthermore, the present application does not use traditional metal wire correction control and does not have the problem of correction displacement and correction angle control of the metal bracket corrector, so it can achieve precise displacement and precise angle correction control. It also allows dental patients to maintain normal tooth brushing and oral cleaning during the tooth correction period, and can also consider the treatment method of tooth correction, tooth shaping, tooth alignment correction, and occlusion correction, which is suitable for dental patients of different age groups such as adults and children. Therefore, it has great potential for clinical application and large-scale commercialization.

[0068] The above description is only illustrative and not limiting, and those of ordinary skill in the art understand that many modifications, changes or equivalents can be made without departing from the spirit and scope of the claims, but all will fall within the protection scope of the present application.
