Description

Orthodontic braces and manufacturing method thereof

The present invention relates to a dental orthodontic brace, in particular to a dental brace that can induce occlusion, correct muscle function, train nasal breathing, assist sleep, reduce snoring, help align teeth, modify the shape of alveolar bones, and make skew, Misaligned teeth can be corrected with orthodontic braces.

Many people have problems with snoring, mouth breathing or sleep disruption; many people have problems with mouth breathing or low tongue position. Mouth breathing can easily cause respiratory allergies, low tongue position, tongue hypertrophy, adenoid and tonsil enlargement, and thus The resulting problems include abnormal tongue function, swallowing disorders, periodontal disease, abnormal tooth alignment, bone growth deformities, and nasal septum curvature. This problem will also affect sleep quality and physical health.

There are many reasons for snoring. The most common reason is that the muscles that originally fixed and opened the throat during sleep relax, causing the muscles in the mouth to retreat and the tongue position to be too low, which in turn causes the respiratory tract to become narrow; the respiratory tract becomes narrow, The wind speed of the inhaled air becomes stronger, causing the relaxed soft palate, uvula, tongue and tonsils to vibrate, thereby making sounds.

In addition to snoring, mouth breathing and sleep apnea, many patients also suffer from Dental problems such as crooked, misaligned teeth, malocclusion, misaligned occlusion, etc. These problems are usually treated through orthodontic treatment to gradually shift and rotate the teeth of the dental patient, and adjust them to the correct occlusal position to achieve a stable position. 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 the central position (Centric Relation, CR). To achieve the correction effect of tooth displacement and tooth rotation, it usually takes about 2 to 3 years. This not only consumes the dental patient's time, but may even cause the patient to give up the correction treatment because it takes too long.

Traditionally, in order to achieve the above-mentioned improvement of snoring, mouth breathing, sleep apnea, and orthodontic correction of crooked teeth and bite misalignment, symptomatic treatment is usually required through two different departments. Because fundamental treatment is not available, the treatment time is extended and the cost of treatment is increased for the patient, which is very unsatisfactory.

"First Embodiment"

Orthodontic treatment is a very special oral treatment. Its purpose is to achieve the technical effects of "orthodontics", "dental plastic surgery" and "dentition correction" through dental treatment methods, so as to improve the dental patients' upper and lower jaw dentition. All can have beautiful, neat and beautiful dental arch contours. In order to achieve the above functions, the present invention provides an orthodontic brace 1 and a manufacturing method thereof. Please refer to FIG. 1 , which is a flow chart of the manufacturing method of the orthodontic brace of the present invention. As shown in Figure 1, first, the 3D spatial information of the oral contour of a dental patient is obtained through a dental software 61 (step T01). The oral contour of the dental patient is preferably obtained by performing an intraoral bite mold and an intraoral bite mold on the dental patient. Impressions or intraoral scans are used to obtain the outline of the gums and teeth in the oral cavity. As shown in Figure 2, the dental patient's oral cavity includes a patient's dentition 91 and a patient's lower dentition 92 (please also refer to Figure 14). The upper dentition 91 includes a plurality of patient teeth 93 , and the patient's lower dentition 92 also includes a plurality of patient lower teeth 94 . Among them, one or more of the teeth 93 affected by the disease are misaligned, offset, skewed, misaligned, inverted, malocclusion, misaligned, etc., and require dental correction. ; In Figure 2, the diseased teeth 93 to be corrected are canine teeth. In other embodiments, the diseased teeth 93 to be corrected may also be incisors or molars.

Please refer to FIG. 3 , which is a schematic diagram showing the digital outline, the digital teeth and the digital concave structure in a dental software. Then, as shown in FIG. 3 , through the dental software 61 , a digital contour 62 corresponding to the patient's oral contour can be formed and displayed (step T02 ); that is, the patient's dentition 91 or the patient's dentition 91 can be formed and displayed. Any concave and convex contours of each tooth in the lower dentition 92 will be faithfully scanned and read into the dental software 61 for display. Next, a digital concave structure 64 is set on at least one digitized tooth 63 of the digitized outline 62 of the dental software 61 (step T03). Here, the digitized teeth 63 with the digitized concave structure 64 correspond to the teeth to be corrected of the dental patient; the digitized teeth 63 without the digitized concave structure 64 correspond to the normal teeth of the dental patient. As can be seen from the enlarged view of Figure 3, the teeth to be corrected (i.e., the canine teeth) of the dental patient are severely skewed or misaligned. The digitized tooth 63 is pushed toward the outer (OutS) direction. Therefore, a digitized concave structure 64 needs to be provided on the inner (InS) side wall of the digitized tooth 63. That is, the digitized concave structure 64 The structure 64 should be disposed on the opposite side of the expected corrective movement direction (U1) of the digitized tooth 63 . Here, the outside (OutS) refers to the outside of the patient's mouth, that is, toward or pointing toward the buccal side, labial side, or facial side. The inner side (InS) refers to the direction toward the patient's tongue or mouth, that is, toward the lingual side.

Next, through the digitized outline 62 of the dental software 61, a physical upper dental model 51 or a physical lower dental model 52 including the physical recessed portion 55 can be output and obtained (step T04, also refer to FIG. 4), and the The physical recessed portion 55 is located on the inner (InS) side wall of the physical upper tooth corresponding portion 53 or on the inner (InS) side wall of the physical lower tooth corresponding portion 54 . The method of outputting and obtaining the physical upper dental model 51 and the physical lower dental model 52 is preferably obtained through 3D printing (3D Printing). Of course, it can also be obtained through traditional mold turning, stacking mold manufacturing, etc. As shown in Figure 4, the output physical upper tooth model 51 includes a plurality of physical upper tooth corresponding parts 53 corresponding to the digitized teeth 63 and the digitized concave structure 64. These physical upper tooth corresponding parts 53 will It is consistent with the patient's multiple diseased teeth 93. In the same way, the output physical lower tooth model 52 will also include a plurality of physical lower tooth corresponding parts 54 (shown in Figure 7) corresponding to the digitized teeth 63 and the digitized concave structure 64, so that these physical lower teeth can The tooth corresponding portion 54 is consistent with a plurality of lower teeth 94 of the patient. In this way, the outlines of the patient's dentition 91 , the patient's lower dentition 92 and their surrounding gums in the dental patient's mouth will be the same as the outlines of the physical upper dental mold 51 and the physical lower dental mold 52 , therefore, the subsequent dental restoration, denture manufacturing, orthodontic shape design and other series of dental laboratory or dental laboratory work can use the physical upper dental mold 51 and the physical lower dental mold 52 as dental The dental working model is a dental working model, and the subsequent design of braces or dentures is implemented through the solid upper dental model 51 and the solid lower dental model 52, without requiring the dental patient to provide real teeth on site.

Next, please refer to Figures 5A and 5B. Figures 5A and 5B illustrate a schematic diagram of a plastic diaphragm being shaped adjacent to the solid upper dental mold. As shown in Figure 5A, a plastic diaphragm 70 is placed adjacent to the physical upper dental mold 51 or the physical lower dental mold 52 (step T05), and then the plastic diaphragm 70 is shaped to deform the plastic diaphragm 70. Attach to the physical upper dental mold 51 or the physical lower dental mold 52 (step T06); Here, the plastic film 70 may be shaped by heating first and then pressurizing, or by direct pressurizing. The purpose of the shaping method of first heating and then pressurizing is to soften the plastic film 70 after being heated and increase the plasticity and ductility of the plastic film 70. Therefore, this method has the advantage of better shaping effect and can make the plastic The diaphragm 70 is almost completely in close contact with the physical upper dental mold 51 or the physical lower dental mold 52 . As shown in FIG. 5B , after the plastic diaphragm 70 is successfully shaped, it can be deformed and closely attached to the physical upper dental mold 51 (or the physical lower dental mold 52 ).

Please refer to FIG. 6 , which is a schematic diagram corresponding to the contours of the hard upper dental sleeve part and the solid upper dental mold after shaping. As shown in Figure 6, at this time, the shaped and deformed plastic diaphragm 70 is separated from the physical upper dental mold 51. Then, the plastic diaphragm 70 attached to the physical upper dental mold 51 can be formed. A rigid upper tooth sleeve part 17 corresponding to the contour of the physical upper tooth mold 51 . In the same way, the plastic diaphragm 70 attached to the physical lower dental mold 52 can also form a hard lower tooth sleeve portion 18 corresponding to the contour of the physical lower dental mold 52 (step T07). Please refer to Figures 7 and 8 at the same time; as shown in Figures 7 and 8, after the plastic diaphragm 70 is formed, the formed hard upper tooth sleeve portion 17 can match the outline of the physical upper tooth corresponding portion 53. They match each other and can be corresponding to and nested with the physical upper dental mold 51 . In addition, because the physical upper tooth corresponding portion 53 of the physical upper dental mold 51 includes a concave physical recessed portion 55, after completing the shaping of the plastic diaphragm 70, the hard upper tooth sleeve portion 17 can be A pushing bump 175 is formed on the side wall of the customized upper tooth position 172. Similarly, the formed hard lower tooth cover portion 18 can match the contour of the physical lower tooth corresponding portion 54 and can be corresponding to and sleeved with the physical lower tooth mold 52 . Because the physical lower tooth corresponding portion 54 of the physical lower tooth mold 52 also includes a concave physical recessed portion 55, after completing the shaping of the plastic diaphragm 70, the hard lower tooth sleeve portion 18 will also be formed in its corresponding portion 54. A pushing bump 185 is formed on the side wall of the customized lower tooth position 182 . In a further embodiment, the hard upper tooth cover portion 17 can also be selectively trimmed and modified with scissors as needed. The outer peripheral contour or the outer peripheral contour of the hard lower tooth cover part 18 makes the outer edge contours of the hard upper tooth cover part 17 and the hard lower tooth cover part 18 closer to the real contour in the patient's oral cavity.

Please refer to Figures 9A and 9B. Figure 9A shows a three-dimensional view of the hard upper tooth cover, the solid upper dental mold, the hard lower tooth cover, and the solid lower dental mold placed into an upper mold and a lower mold. Figure 9B shows The drawing is a cross-sectional view of the hard upper tooth sleeve part, the solid upper dental mold, the hard lower tooth sleeve part, and the solid lower dental mold placed in an upper mold and a lower mold. Next, as shown in FIGS. 9A and 9B , the hard upper tooth cover part 17 and the physical upper dental mold 51 are put into the upper mold cavity 33 of an upper mold 31 , and the hard lower tooth cover part 18 is And the physical lower dental mold 52 is placed into the lower mold cavity 34 of the lower mold 32 (step T08); then the upper and lower molds are closed, as shown in Figure 10, to close the upper mold 31 and the lower mold 32 (step T09). Next, as shown in FIG. 11 , silicone is poured into the upper mold cavity 33 or the lower mold cavity 34 from an injection port 39 (step T10 ), so that the silicone gel fills the upper mold cavity 33 or the lower mold cavity 34 . The space of the lower mold cavity 34. The upper mold cavity 33 of the upper mold 31 is a space reserved by design, and its purpose is to accommodate the combined and mutually nested hard upper dental sleeve portion 17 and the solid upper dental mold 51 . In the same way, the lower mold cavity 34 of the lower mold 32 is also a space reserved by design, and its purpose is to accommodate the combined and mutually nested hard lower tooth sleeve part 18 and the solid lower tooth mold 52. . The spatial contour and shape of the upper mold cavity 33 and the lower mold cavity 34 will directly determine the appearance and configuration of the final orthodontic brace 1. Therefore, the spatial design of the upper mold cavity 33 and the lower mold cavity 34 needs to be considered. Only the current age of the dental patient and the future growth curve of the skull and temporomandibular region can reasonably predict the 3D spatial position of each subsequent tooth, which involves craniofacial structure, temporomandibular structure, physiological anatomy, etc. Multiple considerations; only in this way can we provide the best dental arch correction and bite correction for the dental patient. In this way, after the silicone glue is poured into the upper mold cavity 33 and the lower mold cavity 34 , the silicone glue can cover and cover the periphery of the hard upper tooth cover part 17 and the hard lower tooth cover part 18 . After the silicone hardens, remove the hard The upper tooth cover part 17, the solid upper tooth mold 51, the hard lower tooth cover part 18, the solid lower tooth mold 52 and the hardened silicone (step T11) are used to complete the demoulding step. As shown in Figure 12, the hardened silicone can be formed into a soft tooth cover part 15, wherein the soft tooth cover part 15 includes a receiving part 155, a first fixing part 151, a second fixing part 152, a A third fixing part 153 and a fourth fixing part 154. The first fixing part 151 is located outside the hard upper gear sleeve part 17 (OutS), and the second fixing part 152 is located outside the hard lower gear sleeve part 18 (OutS). , the third fixing part 153 is located inside the hard upper gear sleeve part 17 (InS), the fourth fixing part 154 is located inside the hard lower gear sleeve part 18 (InS), the first fixing part 151 and the third fixing part 153 is located in the upper half of the receiving portion 155 , and the second fixing portion 152 and the fourth fixing portion 154 are located in the lower half of the receiving portion 155 .

Next, the physical upper dental mold 51 is separated from the hard upper tooth cover part 17, and the physical lower dental mold 52 is separated from the hard lower tooth cover part 18 (step T12). After separation, as shown in FIGS. 13A, 13B, and 13C, an orthodontic brace 1 for correcting the patient's patient's dentition 91 and the patient's lower dentition 92 can be formed. The orthodontic brace 1 is composed of a hard upper tooth cover part 17 , a hard lower tooth cover part 18 and a soft tooth cover part 15 . Here, the soft tooth cover part 15 formed of hardened silicone will be tightly and firmly combined with the hard upper tooth cover part 17 and the hard lower tooth cover part 18 due to material characteristics. Can fall off, shake or separate. The hard upper tooth sleeve part 17 includes a plurality of concave customized upper tooth positions 172 and at least one pushing protrusion 175. The plurality of customized upper tooth positions 172 can movably cover the diseased teeth. Row 91, the pushing bump 175 is located on the side wall of the inner side (InS) of the customized upper tooth position 172. The purpose of the pushing bumps 175 is to enhance the effect of correction and strengthen the pushing force of the teeth. Therefore, the pushing bumps 175 can be placed in a customized upper tooth position 172 that needs to be corrected according to the needs. setting; that is, each hard upper tooth sleeve part 17 can be selectively provided with a pushing protrusion 175 in an individual customized upper tooth position 172 . Likewise, it should be hard The lower tooth sleeve part 18 also includes a plurality of concave customized lower tooth positions 182 and at least one pushing protrusion 185. The plurality of customized lower tooth positions 182 can movably cover the lower teeth of the patient. Row 92, the pushing bump 185 is located on the side wall of the inner side (InS) of the customized lower tooth position 182. Each hard-type lower tooth sleeve part 18 may also be selectively provided with a pushing protrusion 185 in an individual customized lower tooth position 182 . In addition, the manufacturing method of the present invention is to set the digital concave structure 64 (as shown in Figure 3) on the digital outline 62 and the digital teeth 63 in step T03, so the physical upper teeth output according to the digital outline 62 The mold 51 and the physical lower dental mold 52 will also include corresponding physical depressions 55 (as shown in Figure 4); then, in step T07, the physical upper dental mold 51 and the physical lower dental mold 52 are attached to The formed hard upper tooth cover part 17 and the hard lower tooth cover part 18 can form push-buttons protruding from the space of the tooth positions on the side walls of the customized upper tooth positions 172 and customized lower tooth positions 182. Resist the bumps 175 and 185 (as shown in Figures 6 and 7).

Please refer to FIG. 14 , which is a schematic diagram of a dental patient using the orthodontic braces to correct teeth. As shown in Figure 14, when a dental patient wears the orthodontic braces 1 of the present invention, the dental patient's dentition 91 and the patient's lower dentition 92 can bite the orthodontic braces 1, so that The patient's dentition 91 is placed in the multiple customized upper tooth positions 172 of the rigid upper denture part 17 , and the patient's lower dentition 92 is placed in the rigid lower dentition part 18 Multiple customized lower tooth positions within 182. At this time, as shown in the enlarged view of FIG. 14 , the tooth end D1 of the diseased tooth 93 needs to be corrected and needs to be pushed toward the outer (OutS) direction; at this time, the hard upper tooth sleeve 17 Pushing against the bump 175 can achieve the technical effect of strengthening the pushing effect and maximizing the correction effect.

In order to achieve a better correction and strengthening effect, the pushing protrusions 175 and 185 of the hard upper tooth cover part 17 and the hard lower tooth cover part 18 are preferably disposed adjacent to the receiving part 155 . That is to say, the pushing bump 175 is located on one third of the side of the customized upper tooth position 172 adjacent to the receiving portion 155 . On the wall, or the pushing bump 185 is located on one third of the side wall of the customized lower tooth position 182 in the direction adjacent to the receiving portion 155 . That is to say, as shown in the enlarged view of FIG. 14 , the pushing bump 175 of the hard upper tooth cover 17 is preferably disposed around the tooth end D1 of the diseased tooth 93 ; the hard lower tooth cover 18 The pushing bump 185 is preferably disposed around the tooth end D1 of the lower tooth 94 of the patient. In order to obtain these structures, when adjusting the position of the digitized concave structure 64 in step T03, the digitized concave structure 64 should be disposed in a direction away from the root 68 of the digitized tooth 63, that is, the The digitized concave structure 64 is disposed at one third of the end D1 of the digitized tooth 63 (see also Figure 3). In this way, the pushing bumps 175 and 185 can be adjusted and changed in their positions, thereby achieving better tooth pushing and correcting effects, and further shortening the time of correcting and correcting tooth displacement.

Furthermore, in the first embodiment shown in FIGS. 2 to 14 , a certain tooth 93 of the dental patient is too inward (InS), and the orthodontic braces 1 of the present invention can help the patient. The patient undergoes dental correction to move the patient's teeth 93 toward the outside (OutS), that is, the expected direction of correction is toward the outside (OutS). At this time, as shown in the enlarged view of FIG. 14 , the dental patient's teeth to be corrected need to be pushed toward the outside (OutS), so the pushing bumps 175 of the hard upper tooth cover part 17 are designed and arranged on the patient's teeth. Customize the upper tooth position 172 on the lateral wall near the inner side (InS). In the same way, the tooth end D1 of the patient's lower tooth 94 needs to be pushed toward the outer (OutS) direction, then the pushing bump 185 of the hard lower tooth sleeve part 18 is designed and set in the customized The lower tooth position 182 is on the lateral wall close to the medial side (InS). Please refer to Figure 3 and Figure 15 at the same time. In order to move the patient's teeth toward the outside (OutS), the digital concave structure 64 must be disposed on the inside of the digital tooth 63 in the dental software 61 ( InS) (that is, the opposite side of the expected correction movement direction U1); in this way, after step T07, a pushing bump 175 can be obtained at the customized upper tooth position. The hard upper tooth sleeve part 17 on the inner (InS) side wall of 172, or a push-off bump 185 is located on the hard lower tooth sleeve part 18 on the inner (InS) side wall of the customized lower tooth position 182 (as shown in Figures 6 and 7 shown).

Here, the hard upper tooth cover part 17 and the hard lower tooth cover part 18 of the orthodontic brace 1 of the present invention are preferably made of dental or medical plastic made of polyurethane material. When performing correction, the orthodontic braces 1 are worn in the dental patient's mouth, because the structure of the upper hard brace part 17 and the lower hard brace part 18 is thin and elastic, and can conform to the patient's condition. The upper teeth 91 or the patient's lower teeth 92 will not rub against the oral gums and cause discomfort. Usually, the hard upper tooth cover part 17 and the hard lower tooth cover part 18 are usually made of transparent material, so they are commonly known as "invisible braces". The function of the hard upper tooth cover 17 and the hard lower tooth cover 18 is that the contours of the customized upper teeth 172 and the customized lower teeth 182 are consistent with the multiple diseased teeth in the patient's mouth. 93. The contours of the patient's lower teeth 94 are the same (this is the meaning of "customized"), so each customized upper tooth position 172 and customized lower tooth position 182 can be accommodated and set. The corresponding patient's teeth 93 and the patient's lower teeth 94, therefore, through the mechanical strength brought by the hard material, the patient's teeth 91 or the patient's lower teeth 92 are misaligned, misaligned, and reversed. Certain teeth that are positioned or crooked, or the dental arch expansion of the patient's dentition 91 or the patient's lower dentition 92 can cause these misaligned teeth to be forced to shift or rotate, and eventually Get into the correct gear position.

In addition, when a dental patient wears the orthodontic braces 1 of the present invention, in addition to the above-mentioned movement of teeth and expansion of the dentition, the relative position of the patient's upper and lower jaws can also be adjusted, so that the patient's dentition 91, disease The affected lower dentition 92 can meet the first type of occlusal tooth position relationship of Class I of Angle's Classification, and allow the dental patient's upper and lower jaw bones to move to the center position (Centric Relation, CR). In terms of relationship, it is used to improve the stability of the upper and lower jaw bite. In this way, the present invention can make the final completed dentition corrected. The set 1 has the function of retaining the upper and lower jaw dentition, so that the upper and lower teeth of the dental patient can align with the cusp & fossa relationship when biting.

It should be noted here that Anger's classification is based on the front-to-back relative relationship between the patient's dentition 91 and the patient's lower dentition 92 in the oral cavity, and divides their occlusion into three categories. Among them, The first type of bite is Class I Neutrocclusion, which shows a normal horizontal overbite, with the upper incisors biting approximately 1 to 3 mm in front of the lower incisors. The second type of bite is Class II distocclusion, which occurs when the upper incisors bite too far forward of the lower incisors, resulting in excessive horizontal overjet (Excess Overjet), or the crowns of the upper incisors retract compensatoryly, resulting in skeletal overbite. phenomenon. The third type of bite is Class III Mesiocclusion, which means the lower incisors bite in front of the upper incisors, resulting in a negative horizontal overjet/anterior crossbite (Negative Overjet/Anterior Crossbite), resulting in protrusion of the lower jaw (commonly known as "bucket") or upper jaw. Symptoms of retraction. The Centric Occlusion (CO) relationship of the teeth is the position where the patient's teeth 93 and the patient's lower teeth 94 bite most closely, that is, the position where the upper and lower teeth bite the largest tooth occlusion surface; Centric Relation , CR) relationship, that is, the joint head of the jaw joint, which is in the middle of the glenoid fossa, is the most stable position. Generally speaking, the ideal occlusal position for stability is a difference of 0.5~1mm between the center occlusion (CO) and the center position (CR). The orthodontic braces 1 of the present invention are expected to allow dental patients to treat dental patients with Class II and Class III malocclusion (Malocclusion) in the Anger classification. The occlusion and tooth position are adjusted so that the dental patient's dentition 91 and the patient's lower dentition 92 are adjusted and corrected toward the Class I first occlusion position.

In addition, as shown in Figure 14, the soft brace part 15 of the orthodontic brace 1 also includes a lingual abutment part 156. The height of the lingual abutment part 156 gradually decreases toward the inner side (InS) (that is, the direction of the tongue), so that First, when the dental patient bites the orthodontic braces 1 and allows the tongue in the oral cavity to By placing it on the tongue butt 156, the height of the tongue can be raised to relax the muscles of the throat and open the airway to avoid airway obstruction and reduce or eliminate the symptoms caused by snoring and low tongue position. "Mouth Breathing Condition". Through the arrangement of the tongue abutment portion 156, the soft brace portion 15 of the orthodontic brace 1 of the present invention can also allow patients with sleep apnea or severe snoring to perform "breathing training" to improve their snoring symptoms and eliminate the symptoms of snoring. Sound and frequency to improve their sleep quality.

Thereby, the orthodontic braces 1 of the present invention can have the functions of growth induction (Eruption Guide) and occlusion induction (Occlusion Guide), and can push, move or rotate individual teeth in a staged manner to allow the growing teeth to The teeth can be adjusted to the correct position, and the hard upper tooth cover part 17 and the hard lower tooth cover part 18 can be used to simultaneously guide the normal growth of the bones.

"Second Embodiment"

There are other embodiments of the manufacturing method for manufacturing the orthodontic brace 1 of the present invention. Please refer to FIG. 16 , which is a schematic diagram of adjusting and setting the digital concave structure through the dental software in the second embodiment. As shown in Figure 16, the teeth to be corrected by the dental patient (shown here as the large molars) are severely crooked or misaligned, and their position is too far to the outside (OutS) of the dentition. Therefore, the direction of correction requires that the crooked and misaligned teeth be corrected. The teeth in the position are pushed inwards (InS); therefore, in step T03, the digitized concave structure 64 needs to be provided on the outer (OutS) side wall of the digitized teeth 63, that is, the digitized concave structure 64 should be It is provided on the opposite side to the expected correction movement direction (U1) of the digitized tooth 63. Then, through the digital outline 62 of the dental software 61, a physical upper dental model 51 or a physical lower dental model 52 including a physical recess 55 on the outer (OutS) side wall of the large molar position can be output (step T04, also see Figure 17). Next, after step T05 and step T06, a hard upper tooth cover portion 17 (or a hard lower tooth cover portion) as shown in Figure 18 can be obtained. 18), the outer contour of the hard upper tooth sleeve portion 17 matches the contours of the plurality of solid upper tooth corresponding portions 53 of the solid upper dental mold 51. Finally, through steps T08 to T12, the hard upper tooth cover part 17 and the hard lower tooth cover part 18 are made into the orthodontic braces 1 according to the second embodiment of the present invention. That is, as shown in Figure 19, the orthodontic braces The hard upper tooth sleeve part 17 of 1 has a push protrusion 175 formed on the outer (OutS) side wall of its customized upper tooth position 172, and the push protrusion 175 located on the outer (OutS) side wall is sufficient. The patient's tooth 93 in the customized upper tooth position 172 is pushed (see also FIG. 14 ), so that the patient's tooth 93 moves toward the inner side (InS) of the patient's dentition 91 to achieve tooth pushing. , correct the technical effect of strengthening, and shorten the correction time. In the same way, the pushing bump 185 can also be formed on the outer (OutS) side wall of the customized lower tooth position 182 of the rigid lower tooth sleeve part 18 to strengthen the tooth pushing of the patient's lower teeth 94. Technical effects of corrective enhancement.

In other embodiments, the pushing bumps 175 of the orthodontic brace 1 of the present invention can only be provided on the side walls of the customized upper tooth position 172 of the hard upper tooth cover part 17 , and the hard lower tooth cover part 18 The customized lower tooth position 182 is not provided with the pushing bump 185; or the pushing bump 185 is only provided on the side wall of the customized lower teeth position 182 of the hard lower tooth sleeve part 18, and the hard upper teeth The customized upper tooth position 172 of the tooth sleeve portion 17 is not provided with the pushing bump 175 . It is even possible that the hard upper tooth sleeve part 17 is provided with a plurality of pushing bumps 175 at multiple customized upper tooth positions 172; or, the hard lower tooth sleeve part 18 is provided at multiple customized lower teeth positions. Bit 182 provides a plurality of push bumps 185 . That is to say, the position and number of the pushing bumps 175 and 185 of the orthodontic brace 1 of the present invention can be adjusted by the dentist depending on the correction speed and correction time requirements.

In this way, the orthodontic braces 1 obtained by the manufacturing method of the present invention are "invisible braces" with a hard upper tooth cover part 17 and a hard lower tooth cover part 18, which can be used to correct misalignment and misalignment in the upper and lower jaw dentitions. , inversion, skew, etc., the dental arch of the upper and lower jaw dentition can also be performed Expansion forces the misaligned teeth to shift or rotate, eventually causing the patient's dentition 91 and the patient's lower dentition 92 to present a neat arc-shaped dental arch, with each tooth in sequence. Arrange neatly and align left and right. Among them, the purpose of the pushing bumps 175 and 185 of the hard upper tooth cover part 17 and the hard lower tooth cover part 18 is to enhance the teeth correction and pushing effect and shorten the time required for correction. In addition, the present invention is based on the growth curve, and the orthodontic braces 1 of the present invention can be customized according to each person's age and dental condition; if the dental patient is in the tooth replacement period, the orthodontic braces 1 of the present invention It has the function of helping bone growth and tooth alignment, which can avoid the need for surgical correction due to bone growth deformity in the future, or the need for tooth extraction and correction due to bite misalignment. In addition, the orthodontic braces 1 use a hard upper tooth cover part 17 and a hard lower tooth cover part 18 as brackets. Because the material is relatively hard, the force for correcting or pushing the teeth is greater, and the overall structure is less difficult. It is bitten and worn by teeth, and the correction time of dental patients can also be shortened. The function of the soft brace part 15 of the orthodontic brace 1 is to correct the occlusion of the upper jaw dentition and the lower jaw dentition, so that the upper jaw dentition and the lower jaw dentition can meet the Class of Angle's Classification. I's first type of occlusal tooth position relationship, and allows the dental patient's upper and lower jaw bones to move to the corresponding relationship of the central position (Centric Relation, CR) to improve the stability of the upper and lower jaw occlusion. In addition, the soft brace part 15 can also treat mouth breathing symptoms (Mouth Breathing), improve sleep apnea and sleep snoring, and allow patients to perform "breathing training" to improve their snoring symptoms and eliminate the sound and frequency of snoring. , improve their sleep quality. Therefore, the present invention uses the hard upper tooth cover part 17, the hard lower tooth cover part 18 of the above-mentioned "invisible braces", and the soft tooth cover part 15 made of soft materials such as rubber and silicone to combine the soft and hard parts to eliminate the above symptoms. The treatment and correction functions are combined in one structure, which has huge potential for dental applications.
