Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of dental orthodontics, and in particular to a dental correction system that can prevent patients from snoring. Background Art

[0002] Snoring is a symptom of making noises during sleep. Mild snoring is usually not a big problem if it is within an acceptable range. However, if the snoring symptoms are severe, it will not only affect the sleep quality of yourself and those around you, but may also turn into "obstructive sleep apnea", which will endanger your health.

[0003] There are many reasons for snoring. The most common reason is that the muscles that originally fixed and stretched the throat relax during sleep, causing the muscles in the mouth to retreat, which in turn causes the airway to become narrow. The narrowing of the airway makes the wind speed of the inhaled air stronger, causing the relaxed soft palate, uvula, tongue and tonsils to vibrate, thus making a sound. Therefore, for snoring caused by this reason, if the patient's lower jaw can be pulled forward to the ideal position during sleep to stretch the airway, snoring can be prevented.

[0004] In recent years, with the development of invisible correction technology, various orthodontic manufacturers have also tried to combine snoring prevention with invisible correction technology to address the problem of snoring. For example, a connecting piece is used to fix the upper jaw front teeth part and the lower jaw back teeth part on both sides of the shell-shaped dental appliance. When the patient wears the shell-shaped dental appliance during sleep, the patient's lower jaw can be kept in a forward position through the connecting piece, thereby opening the airway to suppress snoring.

[0005] However, in the above-mentioned technology combining snoring prevention and invisible correction, the shell-shaped dental device with snoring prevention function often only has an snoring prevention function and is only used for patients to wear when sleeping. The connecting parts are generally fixed on the shell-shaped dental device and cannot be removed. It cannot provide correction function for patients during non-sleeping periods, and the usage scenarios are limited. Utility Model Content

[0034] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined and referenced with each other under the premise of no contradiction.

[0035] The "posterior tooth area" mentioned in each embodiment of the present invention is defined according to the classification of teeth in the second edition of "Introduction to Stomatology" published by Peking University Medical Press, pages 36-38, including premolars and molars, which are teeth 4-8 in the FDI marking method, and teeth 1-3 in the anterior tooth area in the FDI marking method. The teeth in the anterior tooth area include central incisors, lateral incisors and canines.

[0036] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0037] As can be seen from the background technology, orthodontic manufacturers have tried to combine anti-snoring devices with invisible shell-shaped dental appliances. For example, a connector is used to fix the upper jaw part near the front teeth and the lower jaw part near the back teeth on both sides of the shell-shaped dental appliance. When the patient wears the shell-shaped dental appliance while sleeping, the connector can keep the patient's lower jaw in a forward position, thereby opening the airway to suppress snoring. However, the current shell-shaped dental appliance with anti-snoring function often only has an anti-snoring function and is only used for patients to wear while sleeping. The connector is generally fixed on the shell-shaped dental appliance and cannot be removed. The shell-shaped dental appliance cannot provide correction function during non-sleeping periods.

[0038] Based on this, the utility model proposes a dental correction system, comprising a series of shell-shaped dental appliances for progressively moving a patient's dentition from a first tooth layout to a second tooth layout, each shell-shaped dental appliance comprising a maxillary shell-shaped dental appliance, a mandibular shell-shaped dental appliance, and a connector that can be used to connect the maxillary shell-shaped dental appliance and the mandibular shell-shaped dental appliance on the same side, wherein the connector is detachably connected to the maxillary shell-shaped dental appliance and the mandibular shell-shaped dental appliance in at least one wearing sub-time period of each unit wearing time of the shell-shaped dental appliance, so as to keep the patient's lower jaw in a predetermined position during the wearing sub-time period, open the patient's airway, and suppress the patient's snoring; and the connector and the maxillary shell-shaped dental appliance and the mandibular shell-shaped dental appliance are detachably connected to each other in at least one wearing sub-time period of each unit wearing time of the shell-shaped dental appliance. The orthodontic appliances are not connected. The utility model can gradually move the patient's dentition from a first tooth layout to a second tooth layout through a series of shell-shaped dental instruments. In each correction step of gradually moving the first tooth layout to the second tooth layout, in at least one wearing sub-time period (such as the patient's sleeping time period) of the unit wearing time (such as a day), the upper and lower shell-shaped dental appliances of the corresponding shell-shaped dental instrument are connected in a detachable manner by a connecting piece, so that the shell-shaped dental instrument has both a correction function and achieves the purpose of stopping snoring. In at least another wearing sub-time period (such as the patient's non-sleeping time period) of the unit wearing time, the upper and lower shell-shaped dental appliances of the shell-shaped dental instrument are not connected to the connecting piece. At this time, the shell-shaped dental instrument only has a correction function to achieve the purpose of correcting the patient's dentition.

[0039] The implementation details of the dental correction system described in this application will be specifically described below in conjunction with specific embodiments. The following content is only the implementation details provided for ease of understanding and is not necessary for implementing this solution.

[0040] Combination Figure 1 and Figure 2As shown, the dental correction system of the present application includes N shell-shaped dental appliances 10i for progressively moving the patient's dentition from a first tooth layout to a second tooth layout, wherein i=1...N, each shell-shaped dental appliance 10i includes a maxillary shell-shaped dental appliance 10i-a and a corresponding mandibular shell-shaped dental appliance 10i-b, the maxillary shell-shaped dental appliance 10i-a includes a plurality of cavities for accommodating maxillary teeth, and is used to be worn on the patient's maxillary dentition, and the geometry of the cavity is consistent with the stage target layout of the maxillary dentition in the i-th correction step, The mandibular shell-shaped dental appliance 10i-b includes a plurality of cavities for accommodating mandibular teeth and is used for being worn on the mandibular dentition. The geometric shape of the cavity is consistent with the stage target layout of the mandibular dentition in the i-th correction step. The stage target layout is the target layout to be achieved by the mandibular dentition in the current i-th correction step designed when designing the correction plan. The buccal part of the maxillary shell-shaped dental appliance 10i-a close to the anterior teeth is provided with a first fixing portion, and the buccal part of the mandibular shell-shaped dental appliance 10i-b close to the posterior teeth is provided with a second fixing portion. -a, the first fixing portion 1011 of the buccal part close to the front teeth, and the second fixing portion 1012 of the two outer sides of the mandibular shell-shaped dental appliance 101-b close to the posterior teeth are taken as examples, the first fixing portion 1011 and the second fixing portion 1012 include protrusions convexly arranged on the buccal side of the upper and lower mandibular shell-shaped dental appliances, and the connecting member 1013 is provided with a first connecting portion 10131 at one end and a second connecting portion 10132 at the other end. The connecting member 1013 can be connected to the first fixing portion 10131 of the maxillary shell-shaped dental appliance 101-a through the first connecting portion 10131 The fixed portion 1011 is detachably connected and is detachably connected to the second connecting portion 1012 of the mandibular shell-shaped dental appliance 101-b through the second connecting portion 10132. In each unit wearing time (e.g., one day) of the i-th correction step, in a wearing sub-time period when snoring needs to be stopped, such as a sleeping time period (which may include sleeping time at night or sleeping time during the day, such as a patient's lunch break), the connecting member 1013 is connected to the mandibular shell-shaped dental appliance through the first connecting portion 10131 and the second connecting portion 10132, as shown in FIG. Figure 2 As shown, the patient's mandible is kept in a predetermined position to suppress the patient's snoring. During the sub-time period when snoring prevention is not required, such as the non-sleeping time period (such as the patient's work or study time), the connector 1013 is removed from the upper and lower mandibular shell-shaped dental appliances. Then the patient can only wear the maxillary shell-shaped dental appliance on the maxillary dentition and the mandibular shell-shaped dental appliance on the mandibular dentition to achieve continuous correction of the teeth. It can be seen that the utility model fully combines snoring prevention with invisible correction technology, so that each shell-shaped dental appliance in the dental correction system of the utility model can be used for correction during the non-sleeping period, and the correction and snoring prevention are carried out simultaneously during the sleeping period, which not only realizes the correction function but also achieves the purpose of snoring prevention.

[0041] In some embodiments, first fixing portions 1011 may be symmetrically arranged on the left and right buccal sides of the maxillary shell-shaped tooth appliance near the anterior teeth respectively, and second fixing portions 1012 may be symmetrically arranged on the left and right buccal sides of the mandibular shell-shaped tooth appliance near the posterior teeth respectively. By using connecting members 1013 on the left and right sides of the upper and lower jaws of the patient's dentition respectively to hold the patient's mandible in a preset position, the mandibles on both the left and right sides of the patient are subjected to equal sagittal forward forces, improving the patient's comfort.

[0042] It should be noted that although Figure 1 each maxillary and mandibular shell-shaped tooth appliance in each orthodontic step is shown to correspond to a connecting member, it can be understood that since the connecting members in each orthodontic step may have the same structural shape, a single connecting member can be shared among the orthodontic steps, that is, N shell-shaped dental appliances 10i may only correspond to one connecting member; of course, as the connecting member wears during the orthodontic process, a new connecting member can be replaced every several orthodontic steps, that is, N shell-shaped dental appliances 10i may include M connecting members (M < N), and the present application is not limited thereto.

[0043] In the present application, the first tooth layout may be the original tooth layout when the patient starts orthodontic treatment, or the tooth layout after orthodontic treatment for a period of time. The second tooth layout may be the final tooth layout of the patient's orthodontic treatment, or the stage target layout at a certain stage of orthodontic treatment. For example, when obtaining a series of shell-shaped dental appliances that gradually arrange the patient's dentition from the original tooth layout to the final tooth layout based on an orthodontic plan for the patient's dentition, it is possible to design all of these shell-shaped dental appliances to achieve both orthodontic functions and snoring prevention purposes, or it is possible to design the N shell-shaped dental appliances in a certain stage including N orthodontic steps to simultaneously correct and prevent snoring. Of course, it is also possible that the orthodontic plan is designed based on the first tooth layout and the second tooth layout to obtain the N shell-shaped dental appliances. The N shell-shaped dental appliances 10i reflect the changes in tooth structure or arrangement after corresponding orthodontic steps are performed on the dentition of the first tooth layout. The orthodontic process includes at least one orthodontic step (for example, including 20 - 40 orthodontic steps), and each orthodontic step corresponds to a tooth orthodontic state, that is, each orthodontic step corresponds to a shell-shaped dental appliance.

[0044] The first connection part 10131, the second connection part 10132 and the connecting member 1013 are rigid parts, which can be an integral structure, or the first connection part 10131 and the second connection part 10132 can be fixed to the two ends of the connecting member 1013 respectively by bonding or welding, or the first connection part 10131 and the second connection part 10132 can also be connected to the connecting member 1013 in a detachable manner. In some embodiments, taking the second connection part 10132 as an example, the second connection part 10132 includes a connecting body having a first end 10132a and a second end 10132b, and the connecting body is a rod-shaped structure, wherein the first end 10132a is used for detachable connection with the connecting member 1013, and the second end 10132b is used for detachable connection with the corresponding second fixing part 1012, specifically, as Figure 3 As shown, the end of the connector 1013 for correspondingly connecting the first end 10132a is provided with a first mounting hole 10133, and the first end 10132a is connected to the first mounting hole 10133 by threads to achieve fixation. In order to make the first end 10132a and the mounting hole 10133 more securely mounted, the first mounting hole 10133 may be a through hole, and the first end 10132a also includes a mounting cap threadedly connected to the connecting body, and after the connecting body of the second connecting part 10132 is inserted into the second mounting hole 10133, the mounting cap can clamp the connecting body in the first mounting hole 10133, so that the connection between the second connecting part 10132 of the connector 1013 and the second fixing part 10132 on the mandibular shell-shaped dental appliance 101-b is more secure, and preferably, the mounting cap has an arc-shaped outer edge, so that the connector is worn in the patient's mouth to reduce the discomfort to the patient and improve the wearing comfort. Similarly, in the present application, considering the wearing comfort, the edge of the connector 1013 should also be designed with a rounded shape to reduce the foreign body sensation when the patient wears it.

[0045] In the present application, the first fixing portion 1011 is arranged on the part of the maxillary shell-shaped dental appliance 101-a close to the front teeth, and the second fixing portion 1012 is arranged on the part of the mandibular shell-shaped dental appliance 101-b close to the posterior teeth, wherein the part close to the front teeth can refer to the teeth in the posterior teeth area close to the front teeth, or can refer to the teeth in the anterior teeth area, and the part close to the posterior teeth can refer to the teeth in the posterior teeth area, or can refer to the teeth in the anterior teeth area close to the posterior teeth. The setting position of the first fixing portion 1011 and the second fixing portion 1012 can be used as long as the patient's lower jaw can be maintained in the preset position to open the patient's airway and suppress the patient's snoring.

[0046] The following still takes the structure of the second fixing portion 1012 as an example. In some embodiments, the mounting platform in the second fixing portion 1012 can also be formed separately from the mandibular shell-shaped dental appliance 101-b, that is, the mounting platform is a protrusion, and the protrusion can be manufactured separately and fixed to the corresponding position of the buccal surface of the mandibular shell-shaped dental appliance 101-b by bonding or welding, such as Figure 4 As shown; in other embodiments, the second fixing portion includes a mounting platform which is integrally formed with the mandibular shell-like dental appliance, protrudes from the buccal surface of the mandibular shell-like dental appliance away from the buccal surface of the mandibular shell-like dental appliance, and a fixing hole formed on the mounting platform for fixing to the second connecting portion. At this time, a second cavity will be formed between the mounting platform and the teeth wearing the shell-like dental appliance, wherein the fixing hole can be a groove structure, but it can be understood that due to the limited thickness of the diaphragm of the shell-like dental appliance, a fixing hole that is only a groove will result in limited connection strength between the fixing hole and the second connecting portion. Therefore, in order to improve the connection strength between the second connecting portion and the fixing hole, the fixing hole can also be a through hole structure.

[0047] In some embodiments, the detachable connection between the second connecting portion 10132 and the second fixing portion 1012 can be a threaded connection. Specifically, the second end 10132b of the second connecting portion 10132 is provided with an external thread, and the corresponding second fixing portion 1012 is provided with a corresponding fixing hole 1012-a with an internal thread. When the connecting member 1013 needs to be connected to the upper and lower shell-shaped dental orthodontic appliances during sleep, the second end 10132b of the second connecting portion 10132 is screwed into the fixing hole 1012-a in a first direction to match and install with the fixing hole 1012-a on the second fixing portion 1012 to achieve fixation, such as Figure 5As shown; when the connecting piece 1013 needs to be removed from the mandibular shell-like dental appliance, the second end 10132b of the second connecting portion 10132 is screwed out of the fixing hole 1012-a in a direction opposite to the first direction to achieve disassembly, wherein the first direction is a clockwise direction. As mentioned above, in the case where the second fixing portion 1012 is a mounting platform integrally formed with the mandibular shell-like dental appliance 101-b and protruding from the buccal surface of the mandibular shell-like dental appliance 101-b, the fixing hole 1012-a can be a groove located on the second fixing portion 1012, or it can be a through hole located on the second fixing portion 1012. When the fixing hole 1012-a is a through hole, it is only necessary to limit the portion of the second connecting portion 10132 that passes through the through hole from interfering with the teeth located in the cavity. When the patient needs to connect the connecting piece to the upper and lower dental braces to stop snoring during the sleep period, the first connecting part and the second connecting part of the connecting piece only need to be screwed into the corresponding fixing holes. In order to facilitate correction during the non-sleeping period, the first connecting part and the second connecting part of the connecting piece can be screwed out of the corresponding fixing holes. The connection method is simple and convenient for patients to operate by themselves.

[0048] In some preferred examples, if the second fixing portion 1012 is a mounting platform that is protruding from the buccal surface of the mandibular shell-shaped dental appliance 101-b and is integrally formed with the mandibular shell-shaped dental appliance 101-b, a third connecting portion 10132c may also be connected between the first end 10132a and the second end 10132b of the second connecting portion 10132. Figure 6 and Figure 7As shown, when the second connecting part 10132 and the second fixing part 1012 are installed, the second end 10132b will pass through the fixing hole 1012-a and be exposed in the second cavity 1014. At this time, the third connecting part 10132c is at least partially located in the fixing hole 1012-a. In order to prevent the second connecting part 10132 from detaching from the fixing hole 1012-a, a limiting part 10132d is threadedly connected to the second end 10132b to clamp the edge of the fixing hole 1012-a between the limiting part 10132d and the connecting member 1013. When the patient needs to install the connector during sleep, it is only necessary to insert each connector into the corresponding fixing hole, pass the second end of each connector through the corresponding fixing hole, and then screw the limiting part on the second end so that the edge of the fixing hole is stuck between the limiting part and the connector. When the connector needs to be disassembled, it is only necessary to unscrew the limiting part from the second end to remove the connector from the fixing hole. The fixing hole in the connection method of the present application only needs to be a through hole without a threaded shape, which is simple and easy to set. The clamping between the limiting part and the connector makes the connection between the connector and the upper and lower shell-shaped dental appliances more secure. In some preferred examples, since the limiting part 10132d is located in the second cavity 1014, its height in the buccal and lingual direction is less than the height of the second cavity 1014 in the buccal and lingual direction, so that it will not conflict with the teeth worn when worn and produce unnecessary correction force. At the same time, the limiting part 10132d should have an arc-shaped outer edge to improve the patient's comfort.

[0049] In other embodiments, the detachable connection between the second connecting portion 10132 and the second fixing portion 1012 may also be a pluggable connection. Specifically, the second end 10132b of the second connecting portion 10132 is provided with a first mounting portion, such as Figure 8 As shown, the first mounting portion includes a clamping portion 10132c and a guiding portion 10132d disposed adjacent to the clamping portion 10132c. Correspondingly, the second fixing portion 1012 is provided with a concave hollow structure 1012-b. Figure 9-11This is a schematic cross-sectional view of the second end 10132b of the second connecting portion and the hollow structure 1012-b of the second fixing portion 1012 in the buccolingual direction in this embodiment. In this embodiment, the second fixing portion 1012 is a mounting platform bonded or welded to the mandibular shell-shaped dental appliance 101-b close to the posterior teeth. The hollow structure 1012-b on the second fixing portion 1012 includes a guide channel 1012-c and a clamping portion accommodating cavity 1012-d adjacent to the guide channel 1012-c. When the patient needs to install the connecting piece 1013 during sleep, the clamping portion 10132c is passed through the guide channel 1012-c, and the clamping portion 10132c is elastically compressed in the guide channel 1012-c, so that the clamping portion 10132c can pass through the guide channel 1012-c into the desired position. The clamping portion accommodating cavity 1012-d, after entering the clamping portion accommodating cavity 1012-d, the clamping portion 10132c is released to the shape before elastic compression, accommodated in the clamping portion accommodating cavity 1012-d and clamped on the side where the guide channel 1012-c is connected to the clamping portion accommodating cavity 1012-d; when the patient needs to remove the connecting piece 1013 during the non-sleep period, he only needs to pull the second connecting part of the connecting piece 1013 along the pulling-out direction, and the clamping portion 10132c is compressed and elastically deformed under the guidance of the guide channel 1012-c, and then passes through the guide channel 1012-c in the reverse direction and detaches from the corresponding hollow structure 1012-b of the second fixed part 1012, thereby realizing the disassembly of the connecting piece. In this embodiment, the entire installation and disassembly process is simple and quick to operate, which is convenient for patients to operate.

[0050] In some preferred embodiments, in order to further facilitate the insertion, removal and disassembly of the second connecting portion 10132, the clamping portion 10132c includes a first guide portion 10132c-1, a second guide portion 10132c-2 and a slow-release groove 10132c-3, wherein the first guide portion 10132c-1 is arranged adjacent to the free end of the clamping portion 10132c, the second guide portion 10132c-2 is arranged between the first guide portion 10132c-1 and the guide portion 10132d, and the first guide portion 10132c-1 includes an inclined arrangement for guiding the clamping portion 10132c to be inserted into the guide portion 10132d. The first guide slope of the channel 1012-c, the second guide portion 10132c-2 includes a second guide slope that is inclined and used to guide the clamping portion 10132c to disengage from the guide channel 1012-c, the second guide slope makes the size of the second guide portion 10132c-2 gradually increase from the guide portion 10132d to the first guide portion 10132c-1, and the first guide slope makes the size of the first guide portion 10132c-1 gradually decrease from the second guide portion 10132c-2 to the free end, thereby facilitating the insertion and removal of the clamping portion 10132c. The slow-release groove 10132c-3 crosses the clamping portion 10132c along the plug-in and pull-out direction, and one end adjacent to the free end of the clamping portion 10132c is open, so as to provide a slow-release space for the clamping portion 10132c to be compressed and elastically deformed when it is inserted into or removed from the guide channel 1012-c. Moreover, the axial depth H of the release groove 10132c-3 is greater than or equal to the axial length L3 of the clamping portion 10132c. Such a structural design helps the release groove 10132c-3 to better meet the release space required for the elastic deformation of the clamping portion 10132c when inserted into or pulled out of the guide channel 1012-c, thereby ensuring that the clamping portion 10132c can be inserted into or pulled out of the guide channel 1012-c.

[0051] In the case where the second fixing portion 1012 is an installation platform integrally formed with the mandibular shell-shaped dental appliance 101-b and protruding from the buccal surface of the mandibular shell-shaped dental appliance 101-b, in some embodiments, the detachable connection between the second connecting portion 10132 and the second fixing portion 1012 may also be a latch connection, specifically, as Fig.12As shown, the second fixing portion 1012 is provided with a corresponding socket, and the socket is a through hole structure. After the connecting body of the second connecting portion 10132 is inserted into the socket, at least a portion of the second end 10132b is exposed in the second cavity 1014 formed by the mounting platform, and the second end 10132b is provided with a first limiting structure for limiting the connecting body to the socket of the second fixing portion 1012, and the first limiting structure is exposed in the second cavity 1014. When the connecting member 1013 needs to be fixed, the connecting body of the second connecting portion 10132 is limited and fixed in the socket through the first limiting structure. In some preferred embodiments, the first limiting structure includes a limiting hole (not shown in the figure) located on the second end 10132b and a limiting rod 10133 for inserting into the limiting hole. When limiting is required, the limiting rod is inserted into the limiting hole so that the limiting rod interferes with the edge of the socket of the second fixing part 1012 to prevent it from falling off. When disassembly is required, the limiting rod only needs to be gently pulled out of the limiting hole, and the second connecting part 10132 can be pulled out from the socket of the second fixing part 1012. The structure is simple and easy to operate, wherein the limiting rod and the limiting hole can be connected by a thread or an interference fit.

[0052] It should be noted that, although the above-mentioned embodiments only take the connection method between the second connecting part and the second fixed part as an example, it can be understood that the first connecting part and the first fixed part can also adopt the above-mentioned various connection methods, wherein the connection method between the second connecting part and the second fixed part can be the same as the connection method between the first connecting part and the first fixed part, or different. For example, the connection method between the second connecting part and the second fixed part adopts a threaded connection, and the connection method between the first connecting part and the first fixed part can adopt a threaded connection or a pluggable connection, as long as it is a detachable connection method.

[0053] In some embodiments, one of the first connection portion 10131 and the second connection portion 10132 can be connected to the corresponding fixing portion by hooking. In this case, one of the first connection portion 10131 and the second connection portion 10132 can be a hook formed by the corresponding end of the connector 1013, and the corresponding fixing portion forms a structure that can be hooked by the hook on the same side. The other of the first connection portion 10131 and the second connection portion 10132 can be connected to the corresponding first fixing portion 1011 or the second fixing portion 1012 in a detachable manner such as threaded connection, latch connection, or pluggable connection, such as Fig.13As shown. Taking the first connecting portion 10131 of the connecting member 1013 as a hook, for example, the corresponding first fixing portion 1011 located at the part of the maxillary shell-shaped dental appliance close to the front teeth has a shape and size that is convenient for the hook to hook. For example, the first fixing portion 1011 may include a boss protruding from the buccal surface of the maxillary shell-shaped dental appliance for hooking, and the free end of the boss is provided with a limiting portion for preventing the hook from being detached after the hook of the first connecting portion 10131 is hooked, wherein the boss is integrally formed with the maxillary shell-shaped dental appliance, or the boss can be separately manufactured and then installed on the buccal position of the maxillary shell-shaped dental appliance close to the front teeth by bonding or welding. The second connecting portion 10132 of the connecting member 1013 can be detachably connected to the second fixing portion 1012 by one of threaded connection, pin connection, and pluggable connection. The specific connection can refer to the detachable connection method in the aforementioned embodiments, which will not be repeated in this embodiment. When the patient needs to wear the connecting piece 1013 on the upper and lower shell-shaped dental appliances during sleep, the second connecting part 10132 is first connected to the second fixing part 1012 of the mandibular shell-shaped dental appliance close to the posterior teeth, and then the patient's lower jaw is pulled to the preset position, and the first connecting part 10131 in the shape of a hook is hooked on the first fixing part 1012, so that the patient's lower jaw is kept in the preset position, thereby opening the patient's airway and preventing the lower jaw from retracting, thereby achieving the purpose of suppressing the patient's snoring.

[0054] In some embodiments, the second connecting portion 10132 and the second fixed portion 1012 can be movably connected, so that the connecting member 1013 can be rotated around the normal axis of the buccal side where the second fixed portion 1012 is located after being installed on the mandibular shell-shaped dental appliance. When the connecting member 1013 needs to be worn during sleep, the connecting member 1013 can be first connected to the second fixed portion 1012, and the connecting member 1013 can be pulled so that its first connecting portion 10131 is located on the other side of the first fixed portion 1011, and then the bite is closed and the first connecting portion 10131, which is a hook, is hooked on the first fixed portion 1011, so that the patient's mandible remains in a predetermined position; if the connecting member 1013 is to be disassembled, the connecting member 1013 can be first detached from the first fixed portion 1011, and then the connecting member 1013 can be rotated in the opposite direction to a position that does not interfere with the first fixed portion 1011.

[0055] In some preferred embodiments, Fig.14As shown, the second connecting portion 10132 includes a sleeve portion 10132-1 and a traction portion 10132-2, the sleeve portion 10132-1 is a through hole arranged at the corresponding end of the connecting member 1013, the second fixing portion 1012 is provided with a through hole for connecting with the traction portion 10132-2, and the traction portion 10132-2 is movably connected to the corresponding second fixing portion 1012. In some specific examples, such as Fig.15 As shown, the traction part 10132-2 can be an integrated structure, which includes a base 10132-21, a connecting rod 10132-22 extending from the middle of a surface of the base 10132-21, and a working part 10132-23 formed at the end of the connecting rod 10132-22. In this example, in order to allow the traction part 10132-2 to rotate freely in the through hole, the through hole is preferably a circular through hole. Correspondingly, the connecting rod 10132-22 is a cylindrical structure, and the diameter of the through hole should be slightly larger than the diameter of the connecting part 10132-22. In this way, the traction part 10132-2 can be movably installed on the second fixing part 1012. After the sleeve part 10132-1 of the second connecting part 10132 is sleeved on the working part 10132-23 of the traction part 10132-2, the traction part 10132- 2 can rotate around the normal axis of the buccal side surface where the second fixing portion 1012 is located, so that the connecting member 1013 can rotate around the normal axis of the buccal side surface where the second fixing portion 1012 is located after being installed through the second connecting portion 10132; in other specific examples, in order to facilitate the installation of the traction portion 10132-2, the traction portion 10132-2 can also be a split structure. For example, the connecting rod is formed by extending from the surface of one side of the working portion, and the end of the connecting rod is connected to the base by a threaded connection. In this way, during installation, the connecting rod connected to the working portion can be first inserted into the through hole on the second fixing portion 1012, and then the base is threadedly connected to the connecting rod, so that the traction portion 10132-2 can be movably connected to the second fixing portion 1012, wherein, in order to improve the comfort of the patient, the contour edges of the base 10132-21 are all designed with arcs.

[0056] In some other preferred embodiments, in order to realize the movable connection between the second connecting part and the second fixing part, the second connecting part 10132 includes an insertion rod 10132-3 fixedly connected to the end of the connecting member 1013, and the second fixing part 1012 is provided with a through hole for the insertion rod 10132-3 to pass through, and a second limiting structure is provided at the end of the insertion rod 10132-3 away from the connecting member. When the insertion rod 10132-3 is inserted into the through hole, the second limiting structure is exposed in the second cavity 1014 of the mounting platform, and the second limiting structure is used to limit the insertion rod 10132-3 from being separated from the through hole. Fig.16As shown, at this time, the second limiting structure is only used to limit the insertion rod 10132-3 from being separated from the through hole but does not limit the rotation of the insertion rod 10132-3 in the through hole. In this embodiment, the second limiting structure includes a second limiting hole (not shown) located on the insertion rod 10132-3 and a limiting rod 10133 for inserting into the second limiting hole. When the insertion rod 10132-3 is inserted into the through hole and the second limiting hole of the second limiting structure is exposed to the second cavity 1014, the limiting rod 10132-4 is inserted into the second limiting hole to prevent the insertion rod from being disengaged from the through hole. At this time, the second limiting structure is only used to prevent the insertion rod from being disengaged and does not limit the rotation of the insertion rod in the through hole, so that the second connecting part and the second fixing part are movably connected. Similarly, in order to make the rotation of the insertion rod in the through hole more flexible, the through hole on the second fixing part 1012 is a circular through hole. Correspondingly, the insertion rod 10132-3 is cylindrical, and the diameter of the through hole on the second fixing part 1012 should be slightly larger than the corresponding cross-sectional diameter of the insertion rod 10132-3, so that when the insertion rod rotates, the hole wall of the through hole will not interfere with the rotation of the insertion rod.

[0057] In addition, during the correction process of gradually moving the patient's dentition from a first tooth layout to a second tooth layout, the position of the patient's jaw may change. When the position of the patient's jaw changes, if the positions of the first fixing portion and the second fixing portion of the connecting member used to connect the upper and lower shell-shaped dental appliances corresponding to each correction step on the corresponding upper and lower shell-shaped dental appliances remain unchanged, the connecting member will inevitably fail to pull the patient's mandible to the set position. For example, as the correction progresses, the patient's mandible has moved forward. At this time, if the initially designed connecting member and the first fixing portion and the second fixing portion are still in the positions of the upper and lower shell-shaped dental appliances, the connecting member will inevitably fail to be worn. Even if it is forcibly worn, it is difficult to generate a sagittal forward pulling force on the mandible, and it is difficult to achieve the purpose of stopping snoring. Therefore, in order to avoid this situation, in some embodiments, in the N shell-shaped dental instruments 10i for progressively moving the patient's dentition from a first tooth layout to a second tooth layout, the positions of the first fixing part and the second fixing part of the maxillary shell-shaped dental appliance and the mandibular shell-shaped dental appliance of each shell-shaped dental instrument will change with the position of the jaw in which they are located, so that in each correction step, after the connecting member connects the maxillary shell-shaped dental appliance and the mandibular shell-shaped dental appliance through the first fixing part and the second fixing part, the patient's mandible can be kept in the predetermined position. For example, when the patient's mandible moves forward, the positions of the first fixing part and the second fixing part are adjusted according to the amount of the patient's mandibular forward movement. The positions of the adjusted first fixing part and the second fixing part need to be such that after the connecting member is connected through the first fixing part and the second fixing part, the mandible can still be pulled and kept in the preset position to open the patient's airway, thereby suppressing the patient's snoring during sleep.
