Description

Technical Field

[0001] The utility model relates to the field of medical instruments, more specifically to the field of oral appliances, and in particular to an anti-snoring device. Background Art

[0002] The threat of snoring to health has been gradually recognized by people. There are many reasons for snoring, most of which are caused by airway obstruction. The human nasal cavity and oral cavity are connected to the airway. When a person is asleep, the airway tissue collapses due to muscle relaxation, mandibular retraction, and tongue falling back, causing airway obstruction. Especially for obese people, their airways are usually narrower, which makes airway obstruction more likely. One way to open the airway is to stretch the mandible forward to increase the muscle tension of the throat, tongue and soft palate, thereby opening the airway that collapses due to muscle relaxation during sleep. Therefore, the way to stop snoring caused by this reason is to pull the mandible forward to the ideal position to open the airway.

[0003] In recent years, in the field of orthodontics, snoring prevention devices that combine snoring prevention treatment with invisible shell-shaped dental appliances have been developed. They are mainly structures designed on the sides or maxillofacial surfaces of the patient's upper and lower jaws to protrude the mandible. There are mainly two types: one is a connecting rod connected to the left and right sides of the upper and lower mandibular shell-shaped dental appliances, and the connecting rod has a certain rigidity and can keep the patient's mandible in a sagittal forward position that can open the patient's airway; the other is protrusions on the occlusal surfaces of the upper and lower mandibular shell-shaped dental appliances that protrude toward the opposite jaw, respectively. When occluding, the mesial surface of the protrusion of the maxilla and the distal surface of the protrusion of the mandible abut against each other in the sagittal direction, thereby guiding the mandible sagittally forward and keeping it in a position that can open the airway. However, in clinical practice, the applicant found that the lateral or maxillofacial structure is largely restricted by the patient's teeth and dentition structure during the design of protrusion, which will lead to loose sagittal locking and thus cause failure to stop snoring. For example, due to the short clinical crown, it is impossible to design a lateral protrusive structure on the side; or due to the limited jaw opening height, or a large number of missing teeth in the posterior area of ​​the dentition, etc., it is also impossible to complete the maxillofacial protrusive structure design; for such patients, it is often impossible to treat them with the above-mentioned existing snoring prevention structures, which leads to patient loss.

[0004] Therefore, it is necessary to provide a snoring control device with a wide range of applications and a simple structure to provide snoring control diagnosis and treatment for different patients. Utility Model Content

[0027] Compared with the prior art, the present invention adopts the above technical solution, which has at least one of the following beneficial effects:

[0028] (1) The anti-snoring device provided by the utility model has a sagittal retaining device arranged in the anterior tooth area of ​​the maxillary shell-shaped dental appliance. It is not only more applicable, but also does not need to rely on the influence of the patient's tooth body and dentition structure. It is especially suitable for cases where the clinical crown is short, or the jaw opening height is limited, or there are many missing teeth in the posterior tooth area. The anti-snoring device of the present application can only include the maxillary shell-shaped dental appliance, and the sagittal retaining device is arranged in the anterior tooth area of ​​the maxillary shell-shaped dental appliance. Compared with the current anti-snoring device combined with the invisible brace, it can also save raw materials.

[0029] (2) The snoring stopper of the present invention designs the labial surface of the retaining part into a positioning groove that matches the surface convexity of the teeth at the corresponding position of the anterior teeth area of ​​the mandible. On the one hand, the labial surface of the retaining part can better match the teeth when they are in contact with each other, thereby improving the stability during the contact and increasing the comfort of the patient's posterior teeth area. On the other hand, the positioning groove can also quickly guide the teeth at the corresponding position of the mandible of the patient to contact with the corresponding positioning groove.

[0030] (3) The anti-snoring device of the present invention is provided with a reinforcement portion on the labial surface of the retaining portion along the mesiodistal direction or the gingival-maxillary direction. The reinforcement portion is a strip-shaped structure or a point-shaped structure that is raised or recessed toward the teeth on the labial surface of the retaining portion. By increasing the surface curvature of the labial surface of the retaining portion, the deformation resistance of the retaining portion is improved, so that the retaining portion will not be deformed during use, thereby not affecting the anti-snoring effect.

[0031] (4) The snoring stopper of the present invention limits the horizontal movement of the patient's mandible by setting a limit part in the posterior teeth area of ​​the maxillary shell-shaped dental instrument, and the limit part includes a first limit part and a second limit part, and the first limit part and the second limit part are respectively set on the buccal side of the left and right sides of the maxillary shell-shaped dental instrument or respectively set on the lingual side of the left and right sides of the maxillary shell-shaped dental instrument, and the first limit part and the second limit part are respectively abutted against the side surfaces of the teeth at the corresponding positions in the posterior teeth area of ​​the opposite jaw, and are used to limit the horizontal movement of the mandible at the predetermined position, so that the patient's mandible can be kept at the predetermined position in the sagittal direction while being able to remain stable in the horizontal direction, which is beneficial to improving the effect of stopping snoring.

[0047] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the various embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings. However, it can be understood by those skilled in the art that in each embodiment of the utility model, many technical details are proposed in order to enable readers to better understand the utility model. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed for protection of the utility model can also be implemented. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the utility model.

[0048] Directional terms such as "upper", "lower", "left", and "right" used in the description herein are directions in the drawings and do not refer to special limitations. Unless otherwise specified and limited, the term "connection" in this article should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, and can be directly connected or indirectly connected through an intermediate medium.

[0049] 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, teeth 4-8 in the FDI notation, and teeth 1-3 in the anterior tooth area in the FDI notation. The teeth in the anterior tooth area include central incisors, lateral incisors and canines.

[0050] From the background technology, it can be seen that in recent years, in the clinical practice of using invisible braces to stop snoring, the applicant has found that the lateral or maxillofacial structure is largely restricted by the patient's teeth and dentition structure during the design of protrusion, especially the condition of the patient's teeth and dentition structure in the posterior area. If the patient's teeth or dentition structure are not in good condition, it may cause the sagittal locking to be loose, thereby leading to the failure of stopping snoring, that is, the application cases of snoring prevention devices are limited.

[0051] Based on this, the applicant proposed an anti-snoring device with a simple structure and not limited by case conditions, comprising a maxillary shell-shaped dental instrument and a sagittal retaining device arranged in the anterior tooth area of ​​the maxillary shell-shaped dental instrument; the sagittal retaining device comprises a retaining portion protruding from a position between the lingual side and the labial side of the maxillary anterior tooth area toward a corresponding position of the mandibular anterior tooth area; when worn, the lingual side surface of the teeth at the corresponding position of the mandibular anterior tooth area abuts against the labial surface of the retaining portion to maintain the mandible sagittally upward at a predetermined position to open the patient's airway, thereby preventing snoring.

[0052] Please see Figures 1 to 6 As shown, the snoring stopper 100 of the present application comprises a maxillary shell-shaped dental appliance 1 and a sagittal retaining device arranged in the anterior teeth area of ​​the maxillary shell-shaped dental appliance 1; the maxillary shell-shaped dental appliance 1 comprises a plurality of cavities 10 arranged in a U shape for accommodating a plurality of teeth 3; the sagittal retaining device comprises a retaining portion 21, the retaining portion 21 protrudes from a position A between the lingual side and the labial side of the maxillary anterior teeth area toward a corresponding position of the mandibular anterior teeth area, specifically, as shown in FIG. Figure 3 As shown, the retaining portion 21 in this embodiment protrudes from position B of the cavity 10 toward the mandibular anterior teeth area, and position B is located in the interval of position A between the lingual side and the labial side of the maxillary anterior teeth area. When worn, the lingual side surface 31 of the tooth 3 at the corresponding position of the mandibular anterior teeth area abuts against the labial surface of the retaining portion 21, which can maintain the patient's mandible in a sagittal upward position to open the patient's airway. When the patient is in a sleeping state, a sagittal forward force F1 can be given to the patient's mandible to prevent the patient's mandible from retreating and maintain the patient's mandible in the predetermined position. Specifically, when determining the predetermined position, it can be determined by 60% to 100% of the maximum protrusion of the patient's mandible, for example, the patient's mandible can be protruded between 70% and 80% of the maximum protrusion, or 75% of the maximum protrusion. The mandibular position at this position enables the patient to obtain a good snoring control effect and be more comfortable. Among them, as Figure 4 The figure shows the relative position of the upper and lower jaws of the patient in a normal state. Figure 5 The relative positions of the upper and lower jaws of the patient shown in FIG. 1 when the mandible is protruded to the maximum protrusion position, and the maximum protrusion amount L of the mandible described in the present application is as follows: Figure 6As shown in , it is the distance from the mandibular position C of the patient's mandible when it is in a normal occlusal state to the mandibular position D when it is sagittally extended forward to the maximum position D. The technical solution of the present application does not need to rely on the influence of the patient's tooth body and dentition structure, especially for the case of short clinical crowns, or limited jaw opening height, or a large number of missing teeth in the posterior teeth area, and the snoring stopper 100 of the present application can only include the maxillary shell-shaped dental appliance 1 worn on the patient's upper jaw, and the sagittal retaining device is arranged in the anterior teeth area of ​​the maxillary shell-shaped dental appliance 1, which can save nearly half of the material compared with the current snoring stopper 100 combined with the invisible brace. Of course, it can be understood that the snoring stopper 100 of the present application can also include a mandibular shell-shaped dental appliance worn on the patient's lower jaw, and this embodiment will be described in subsequent embodiments.

[0053] In another embodiment, see Figures 7 to 10 As shown, the sagittal retaining device also includes an auxiliary portion 23, which is protruding from the position A between the lingual side and the labial side of the maxillary anterior teeth area toward the corresponding position of the mandibular anterior teeth area. The auxiliary portion 23 is located on the labial side of the retaining portion 21, and the auxiliary portion 23 and the retaining portion 21 enclose a receiving space 24 capable of accommodating the tooth 3 at the corresponding position of the mandibular anterior teeth area. When worn, the labial side surface 33 of the tooth 3 at the corresponding position of the mandibular anterior teeth area contacts the lingual surface of the auxiliary portion 23, as shown in FIG. Fig. 9 As shown, with such a design, the tooth 3 in the mandibular anterior teeth area of ​​the patient can be accommodated in the accommodating space 24, the lingual side surface 31 of the tooth 3 abuts against the labial side of the retaining portion 21, and the labial side surface 33 of the tooth 3 abuts against the lingual side of the auxiliary portion 23, so that the tooth 3 can be stably and securely limited in the accommodating space 24 in the sagittal direction, and the snoring control effect can be better guaranteed; in another embodiment, when worn, the lingual side of the tooth 3 in the mandibular anterior teeth area of ​​the patient abuts against the labial side of the retaining portion 21, and the labial side surface 33 of the tooth 3 at the corresponding position of the mandibular anterior teeth area and the lingual surface of the auxiliary portion 23 are set at a first preset distance L1, as shown in FIG. Fig.10 As shown, the teeth 3 can be given a certain amount of space for movement in the sagittal direction. With this design, when the patient's lower jaw grinds or opens the mouth slightly during sleep, the patient can have a certain degree of comfort. In clinical practice, the position of the prime auxiliary part 23 can be designed according to the needs of the patient.

[0054] In one embodiment, the first preset distance L1 can be 1mm to 3mm, and such a range has been proven to be more conducive to the treatment of snoring. For example, when the first preset distance L1 is 3mm, it can provide space for the patient's lower jaw to grind teeth or open the mouth slightly during sleep, and it is not easy to slip out of the accommodation space 24, so as to ensure the anti-snoring effect; when the first preset distance L1 is 1mm, while providing space for the patient's lower jaw to move, it can also accommodate the patient's lower jaw relatively stably in the accommodation space 24, so as to ensure the anti-snoring effect; in addition, considering the comfort of the patient wearing, the first preset distance L1 can also be designed to be 2mm in clinical practice.

[0055] In one embodiment, see Fig.11 and Fig.12 As shown, the sagittal retaining device can be symmetrically arranged along the tooth midline Z. The sagittal retaining device can be a case where it only includes the retaining portion 21 (such as Fig.11 As shown), it may also include a holding portion and an auxiliary portion 23 (as shown Fig.12 As shown, since it is a labial frontal view, the retaining portion located on the lingual side is not shown. Such a design can enable the left and right sides of the patient to give the patient's mandibular symmetrical sagittal forward force. On the one hand, it can increase the patient's comfort. On the other hand, it can also avoid the patient's mandibular anterior teeth from being subjected to asymmetric forces on the left and right sides, causing unexpected movement.

[0056] In one embodiment, the sagittal retaining device is arranged at a position that can cover 2 to 6 teeth in the maxillary anterior region, and further preferably, the length of covering 3 or 4 teeth is preferred. For example, please continue to refer to Fig.11 As shown, it is better to extend from the 1 / 2 position of the left lateral incisor of the patient's maxillary maxilla to the 1 / 2 position of the right lateral incisor in the mesiodistal direction. With this design, the total length covering 3 teeth can not only ensure the effective length of the sagittal retaining device when it abuts against the teeth in the mandibular anterior area to a certain extent, and ensure its mechanical strength, thereby effectively limiting the patient's mandibular recedement; it can also reduce the foreign body sensation in the patient's anterior area, and achieve a good balance between the anti-snoring effect and the foreign body sensation.

[0057] In one embodiment, see Fig.13 As shown, in order to increase the stability of the teeth in the mandibular anterior region of the patient when they rest against the labial surface of the retaining portion 21, the present application designs the labial surface of the retaining portion 21 into a positioning groove 25 that matches the surface contour of the teeth at the corresponding position of the mandibular anterior region. At the same time, the positioning groove 25 can also guide the teeth at the corresponding position of the patient's mandibular anterior region into the corresponding positioning groove 25.

[0058] In another embodiment, in order to further enhance the patient's comfort, when the sagittal retaining device only includes the retaining portion 21, the overall shape of the labial surface of the retaining portion 21 along the mesiodistal direction can also be designed to be an arc shape consistent with the patient's dental arch; when the sagittal retaining device includes both the retaining portion 21 and the auxiliary portion 23, the overall shape of the labial surface of the auxiliary portion 23 along the mesiodistal direction can be designed to be an arc shape consistent with the patient's dental arch; with such a design, when the lip muscles are in contact with the labial surface of the retaining portion 21 or the auxiliary portion 23, the lip muscles can be evenly covered on the labial surface, thereby reducing discomfort.

[0059] In one embodiment, the sagittal retaining device and the maxillary shell-shaped dental appliance 1 are an integrally formed structure. For example, when a hot pressing film process is used, after a solid dental model with a sagittal retaining device is printed out, it is directly pressed and formed by hot pressing film. This integrally formed mechanism makes the hot pressing film process relatively simple and easy to operate. It is understandable that, in another embodiment, the sagittal retaining device can also be a separate structure from the maxillary shell-shaped dental appliance 1, which are manufactured separately and then installed in the anterior tooth area of ​​the maxillary shell-shaped dental appliance 1 by bonding or welding. The technical solution of the split structure allows the sagittal retaining device to be installed according to the doctor's instructions when snoring is needed; the sagittal retaining device with different mandibular protrusion amounts can also be replaced in time according to the progress of the snoring treatment, which is flexible to use.

[0060] In one embodiment, please continue to refer to Figure 3 As shown, the retaining portion 21 protrudes from the predetermined position B of the cavity 10 where the tooth 3 in the maxillary anterior teeth region is located toward the mandible, and the predetermined position is between the gum line of the tooth 3 covered by the retaining portion 21 and the position 1 / 2 of the crown height of the gum line of the tooth 3 covered by it. When the sagittal retaining device includes both the retaining portion 21 and the auxiliary portion 23, please continue to refer to Fig. 9As shown, the retaining portion 21 protrudes from the predetermined position B of the cavity 10 where the teeth 3 of the maxillary anterior teeth area are located to the mandible, and the auxiliary portion 23 protrudes from the predetermined position E of the cavity 10 where the teeth 3 of the maxillary anterior teeth area are located to the mandible, and the predetermined positions are located between the gum line of the teeth 3 covered by the retaining portion 21 and the auxiliary portion 23 and the position 1 / 2 of the crown height of the gum line of the teeth 3 covered by them. The design of protruding from the predetermined position to the mandible enables the maxillary shell-shaped dental instrument 1 to wrap part of the teeth 3 of the anterior teeth area, which is beneficial to the retention effect of the maxillary shell-shaped dental instrument 1. If the predetermined position is located above the patient's gum line, that is, protruding to the mandible, the wrapping force of the maxillary shell-shaped dental instrument 1 is insufficient, which will result in a weak retention force of the maxillary shell-shaped dental instrument 1, and may cause the retaining portion 21 to tilt toward the tongue side, ultimately affecting the anti-snoring effect. It is further explained that the retaining portion 21 extends from the predetermined position B area of ​​the cavity 10 where the tooth 3 in the maxillary anterior teeth area is located, and the auxiliary portion 23 extends from the predetermined position E area of ​​the cavity 10 where the tooth 3 in the maxillary anterior teeth area is located, and the teeth 3 covered by the sagittal retaining portion protrude toward the mandible along the corresponding two sides (lingual side and labial side) in the sagittal direction, and are connected at the position near the incisal end of the covered tooth 3, and do not contact the incisal end of the covered tooth 3. Such a design can prevent the covered tooth 3 from being subjected to the force from its cavity 10 along the gingival and jaw direction, so as to prevent the tooth 3 from undergoing unexpected movement.

[0061] In another embodiment, as described in the previous embodiment, if the protruding predetermined position of the retaining portion 21 is closer to the gum line, or even at the gum line, the wrapping force of the maxillary shell-shaped dental device 1 on the front teeth 3 covered by it is weaker, which may easily cause insufficient retention force, thereby affecting the anti-snoring effect. Therefore, the maxillary shell-shaped dental device 1 of the present application may also include a retention portion 11; when the sagittal retaining device only includes the retaining portion 21, the retention portion 11 is formed by the labial surface of the cavity 10 of the tooth 3 covered by the retaining portion 21 extending from the gum line 32 toward the gums of the mandible, please refer to Fig.14 When the sagittal holding device includes a holding portion 21 and an auxiliary portion 23, the retaining portion 11 is formed by the labial surface of the cavity 10 of the tooth 3 covered by the auxiliary portion 23 extending from the gum line 32 toward the gums of the jaw, see Fig.15 As shown; when worn, the retaining portion 11 can abut against the gum surface of the present jaw, and the design of the retaining portion 11 enhances the rigidity and retaining force of the maxillary shell-shaped dental appliance 1, thereby reducing the probability of the maxillary shell-shaped dental appliance 1 being detached and ensuring the anti-snoring effect.

[0062] In one embodiment, please continue to refer to Fig.14 and Fig.15 , and combined with Fig.16As shown, the thickness dimension h of the retaining portion 21 along the sagittal direction ranges from 2 mm to 5 mm, for example, 3 mm. The thickness dimension h within the range can ensure the mechanical strength of the retaining portion 21 and prevent the retaining portion 21 from breaking when it abuts against the mandibular anterior teeth; when the thickness dimension h of the retaining portion 21 exceeds 5 mm, the patient will have obvious discomfort of foreign body; when the thickness dimension h of the retaining portion 21 is less than 2 mm, it is easy to break and difficult to demold during production.

[0063] In one embodiment, see Fig.17 As shown, the depth H of the accommodation space 24 along the gingival and maxillomandibular direction is set to: when worn, the accommodation space 24 at least covers 1 / 3 of the crown height of the tooth at the corresponding position of the mandibular anterior teeth area. The depth H refers to the distance from the lowest point of the accommodation space 24 in the gingival and maxillomandibular direction to the highest point of the retaining portion 21 in the gingival and maxillomandibular direction. Such a distance is set to ensure the effective area of ​​the labial side of the retaining portion 21 against the lingual side of the tooth at the corresponding position of the mandibular anterior teeth area, so as to stably maintain the patient's mandible at the predetermined position to open the patient's airway.

[0064] In some embodiments, please continue to see Fig.17As shown, the labial surface of the auxiliary part 23 is a plane or an arc in accordance with the dental arch along the mesiodistal direction. When the labial surface of the auxiliary part 23 is an arc in accordance with the dental arch along the mesiodistal direction, the patient's lip muscles 4 and the arc of the labial surface of the auxiliary part 23 are in uniform contact, which can relieve discomfort. When the labial surface of the auxiliary part 23 is a plane along the mesiodistal direction, the labial surface and the patient's coronal plane G are set at a preset angle α; when the labial surface of the auxiliary part 23 is an arc in accordance with the dental arch along the mesiodistal direction, the tangent N of the auxiliary part 23 passing through the highest point M of the labial surface along the gingival-mandibular direction and the patient's coronal plane G are set at a preset angle α. Specifically, the coronal plane is indicated by G, M is the highest point of the labial surface of the auxiliary part 23, and the tangent of the labial surface of the auxiliary part 23 in the gingival-mandibular direction is indicated by N, wherein the preset angle α is 5° to 30°, for example, it can be 15° to 20°, and can also be 20°. The setting of the preset angle α can enable the accommodating space 24 to accommodate the mandibular anterior teeth at different predetermined positions in the sagittal direction, or to accommodate the mandibular anterior teeth with lip inclination. For example, when the preset angle α is 5°, the accommodating space 24 can accommodate the mandibular anterior teeth of the patient more stably, which is applicable to most patients; when the preset angle α is 30°, the sagittal space of the accommodating space 24 is larger, which can accommodate cases with mandibular lip inclination, and can also be applicable to cases when the mandibular needs to be guided forward to a larger protrusion, and at this angle, the patient's mandibular has space to open the mouth; the preset angle α can also be designed to be 20°. This angle design can not only reduce the strong foreign body sensation caused by the excessive volume of the sagittal retaining device in the sagittal direction, but also take into account the comfort of the patient wearing and the applicability of clinical application. Therefore, in clinical practice, the preset angle can be selected purposefully based on the comprehensive anti-snoring effect and patient comfort.

[0065] In one embodiment, the labial side of the retaining portion 21 may also be provided with a first reinforcement portion, which may be provided in the mesiodistal direction or in the gingival-mandibular direction, and the specific structure may be a strip-shaped structure or a point-shaped structure protruding toward the teeth on the labial surface of the upper portion of the retaining portion 21, or a strip-shaped structure or a point-shaped structure recessed toward the teeth. By increasing the surface curvature of the labial surface of the retaining portion 21, the deformation resistance of the retaining portion 21 is increased, so that the retaining portion 21 will not be deformed during use, thereby affecting the anti-snoring effect.

[0066] In one embodiment, see Figures 18 to 21As shown, the anti-snoring device 100 may also include a mandibular shell-shaped dental device 2 worn on the patient's mandibular dentition. Similarly, the mandibular shell-shaped dental device 2 includes a plurality of cavities arranged in a U shape for accommodating a plurality of teeth. At this time, when worn, the labial surface of the retaining portion 21 abuts against the lingual surface of the cavity at the corresponding position of the anterior teeth area of ​​the mandibular shell-shaped dental device 2 to prevent the patient's mandible from receding and to retain the patient's mandible at the predetermined position. A protrusion 20 may also be provided on the labial side of the anterior teeth area of ​​the mandibular shell-shaped dental device 2 protruding toward the distal teeth. When worn, the patient's lip muscles 4 contact the protrusion 20 to apply a sagittal X-backward force F2 to the teeth 3 at the corresponding position of the mandibular anterior teeth area, which is used to partially offset the sagittal X-forward force F3 of the retaining portion 21 on the teeth 3, thereby avoiding the lip tilt of the mandibular anterior teeth. Specifically, when F2<F3, the force F2 can partially offset the force F3 applied to the tooth 3 in the sagittal direction X forward when the retaining portion 21 abuts against the tooth 3, thereby reducing the amplitude of the labial inclination of the mandibular anterior teeth; when F2=F3, the force F2 is sufficient to completely offset the force F3 applied to the tooth 3 in the sagittal direction X forward when the retaining portion 21 abuts against the tooth 3, thereby avoiding the labial inclination of the mandibular anterior teeth.

[0067] For further explanation, please continue to see Fig. 20 As shown, when the sagittal retaining device includes a retaining portion 21 and an auxiliary portion 23, the raised portion 20 and the auxiliary portion 23 are arranged at a second preset distance L2 in the gingival and maxillary direction, and the second preset distance L2 can range from 0 to 3 mm. This design is to ensure that the raised portion 20 and the auxiliary portion 23 do not interfere with the labial side of the teeth 3 in the patient's mandibular anterior teeth area; it can be understood that the second preset distance L2 can be 0.

[0068] In some embodiments, see Fig. 22 and Fig.23 As shown, the anti-snoring device 100 can also be provided with a limiter for limiting the horizontal movement of the patient's mandible, and the limiter includes a first limiter 51 and a second limiter 52, and the first limiter 51 and the second limiter 52 are respectively provided on the buccal side of the left and right sides of the maxillary shell-shaped dental device 1 or respectively provided on the lingual side of the left and right sides of the maxillary shell-shaped dental device 1. When worn, the first limiter 51 and the second limiter 52 are respectively abutted against the side surfaces of the teeth at the corresponding positions of the posterior teeth area of ​​the opposite jaw, so as to limit the horizontal movement of the mandible at the predetermined position. Specifically, as Fig. 22The first limiting member 51 and the second limiting member 52 shown are both located on the buccal surfaces of the cavities on the left and right sides of the posterior teeth area of ​​the maxillary shell-shaped dental instrument 1. More preferably, the first limiting member 51 and the second limiting member 52 are symmetrically arranged about the tooth midline Z. When the first limiting member 51 abuts against the buccal side of the tooth at the corresponding position of the left posterior teeth area of ​​the mandible, the first limiting member 51 blocks the horizontal movement path of the patient's mandible to the left; when the second limiting member 52 abuts against the buccal side of the tooth at the corresponding position of the right posterior teeth area of ​​the mandible, the second limiting member 52 blocks the horizontal movement path of the patient's mandible to the right, thereby stably limiting the patient's mandible in the horizontal direction. Fig.23 The first limiting member 51 and the second limiting member 52 shown are both located on the lingual surfaces of the cavities on the left and right sides of the posterior teeth area of ​​the maxillary shell-shaped dental instrument 1. More preferably, the first limiting member 51 and the second limiting member 52 are symmetrically arranged about the tooth midline Z. When the first limiting member 51 and the second limiting member 52 are respectively abutted against the lingual sides of the teeth at the corresponding positions in the maxillary posterior teeth area, the paths of the patient's mandibular horizontal movement to the left and right are respectively blocked, thereby stably limiting the patient's mandibular horizontal position. It is understandable that when the snoring stopper 100 also includes the mandibular shell-shaped dental instrument 2, the first limiting member 51 and the second limiting member 52 are respectively abutted against the side surfaces of the cavities at the corresponding positions in the posterior teeth area of ​​the mandibular shell-shaped dental instrument 2, thereby stably limiting the patient's mandibular horizontal position.

[0069] In some embodiments, see Figure 24 to Figure 27 As shown, the first limiting member 51 and the second limiting member 52 are arranged at different jaws. Specifically, as shown in FIG. Fig.24 As shown, it is illustrated that the first limiting member 51 is arranged on the buccal surface of the left side of the maxillary shell-shaped dental instrument 1, and the second limiting member 52 is arranged on the lingual surface of the right side of the mandibular shell-shaped dental instrument 2. At this time, the first limiting member 51 abuts against the buccal surface of the cavity at the corresponding position of the mandibular posterior teeth area, blocking the horizontal movement path of the patient's mandible to the left, and the second limiting member 52 abuts against the lingual surface of the cavity at the corresponding position of the maxillary posterior teeth area, blocking the horizontal movement path of the patient's mandible to the right, thereby stably limiting the patient's mandible in the horizontal direction. Fig.25As shown, it is illustrated that the first limiting member 51 is arranged on the lingual surface of the left side of the mandibular shell-shaped dental instrument 2, and the second limiting member 52 is arranged on the buccal surface of the right side of the maxillary shell-shaped dental instrument 1. At this time, the first limiting member 51 abuts against the lingual surface of the cavity at the corresponding position of the maxillary posterior teeth area, blocking the horizontal movement path of the patient's mandible to the left, and the second limiting member 52 abuts against the buccal surface of the cavity at the corresponding position of the mandibular posterior teeth area, blocking the horizontal movement path of the patient's mandible to the right, thereby stably limiting the patient's mandible in the horizontal direction. Fig.26 As shown, it is illustrated that the first limiting member 51 is arranged on the lingual surface of the left side of the mandibular shell-shaped dental instrument 2, and the second limiting member 52 is arranged on the buccal surface of the right side of the maxillary shell-shaped dental instrument 1. At this time, the first limiting member 51 abuts against the lingual surface of the cavity at the corresponding position of the mandibular posterior teeth area, and the second limiting member 52 abuts against the buccal surface of the cavity at the corresponding position of the maxillary posterior teeth area, and together they stabilize the patient's mandible in the horizontal direction. Another example is Fig. 27 As shown, it is illustrated that the first limiting member 51 is arranged on the lingual surface of the left side of the maxillary shell-shaped dental instrument 1, and the second limiting member 52 is arranged on the buccal surface of the right side of the mandibular shell-shaped dental instrument 2. At this time, the first limiting member 51 abuts against the lingual surface of the cavity at the corresponding position of the maxillary posterior teeth area, blocking the horizontal movement path of the patient's mandible to the right, and the second limiting member 52 abuts against the buccal surface of the cavity at the corresponding position of the maxillary posterior teeth area, blocking the horizontal movement path of the patient's mandible to the left, thereby stably limiting the patient's mandible horizontally.

[0070] In one embodiment, the first stopper 51 and the second stopper 52 each include an action surface adjacent to the opposing teeth or the cavity accommodating the opposing teeth, and the shape of the action surface matches the shape of the tooth side surface or cavity side surface of the opposing teeth against which the first stopper 51 or the second stopper 52 abuts. Such a design can make the first stopper 51 or the second stopper 52 and the corresponding cavity side surface of the opposing jaw fit better when abutting, improve the stability when abutting, and increase the comfort of the patient's posterior teeth area.

[0071] In one embodiment, the action surface is further provided with a second reinforcement portion arranged in the mesiodistal direction or the gingival-maxillary direction, and the second reinforcement portion is a strip-shaped structure or a point-shaped structure that is convex or concavely arranged in the horizontal direction toward the jaw direction of the action surface. By increasing the surface curvature of the action surface of the first limiting member 51 or the second limiting member 52, the deformation resistance of the first limiting member 51 or the second limiting member 52 is improved, so that the first limiting member 51 or the second limiting member 52 will not be deformed during use, thereby affecting the limiting effect.
