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 may collapse 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, a snoring prevention device that combines snoring prevention treatment with invisible shell-shaped dental appliances has been developed. Its main design is to set a sagittal device to guide the mandible forward between the upper and lower shell-shaped dental appliances, so that the patient's mandible can be kept in a sagittal forward position, thereby opening the airway to suppress snoring. The common sagittal device for guiding the mandible to prevent snoring currently includes, for example, a connecting rod movably connected to the left and right sides of the upper and lower shell-shaped dental appliances, or a protrusion protruding toward the opposite jaw on the occlusal surfaces of the upper and lower shell-shaped dental appliances. When occluding, the mesial surface of the protrusion of the upper jaw and the distal surface of the protrusion of the mandible abut against each other in the sagittal direction, so that the mandible is sagittally guided forward and kept in a position that can open the airway. However, such anti-snoring devices all have some shortcomings. For example, in the former anti-snoring device, the greater the rigidity of the connecting rod, the better the effect of opening the airway and keeping it in the corresponding position, and the lower jaw can be restricted in horizontal left and right movement. However, if the rigidity of the connecting rod located in the patient's mouth is too large, it will obviously cause discomfort to the patient. Therefore, the usual clinical practice is to reduce the rigidity of the connecting rod in order to increase the patient's comfort, that is, to select a connecting rod with a certain elasticity; but such a design will cause the connecting rod to deform elastically in the horizontal left and right directions due to the elasticity of the connecting rod, resulting in horizontal left and right movement of the patient's lower jaw. After wearing it for a long time, the jaw will be offset, which brings unexpected results to the patient and causes trouble to the patient. For another example, in the latter anti-snoring device, the device that guides the lower jaw forward in the sagittal direction is located on the occlusal surface, and it is even more unable to restrict the horizontal left and right movement of the patient's lower jaw, so after wearing it for a long time, the jaw will also be offset, which is an unexpected result.

[0004] Therefore, it is necessary to provide a snoring stopper that can limit the horizontal left-right movement of the patient's mandible. Utility Model Content

[0051] 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.

[0052] 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.

[0053] 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.

[0054] As can be seen from the background technology, in recent years, in the field of orthodontics, a snoring device that combines snoring treatment with an invisible shell-shaped dental appliance has been developed. It can guide the mandible forward in the sagittal direction and keep the mandible in a position to open the airway. However, in clinical practice, either the rigidity of the connecting rod is sacrificed to ensure comfort, resulting in horizontal movement of the patient's mandible in the left and right directions; or in a snoring device that guides the mandible forward by abutting the upper and lower protrusions, the patient's mandible may move in the left and right directions horizontally. After wearing the above-mentioned snoring device for a long time, undesirable results such as jaw deviation may occur.

[0055] Based on this, the applicant proposes a snoring stopper capable of limiting the horizontal movement of the patient's mandible, comprising a snoring stopper body and a limiting portion for limiting the horizontal movement of the patient's mandible; the snoring stopper body comprises a maxillary shell-shaped dental instrument worn on the patient's maxillary dentition, a mandibular shell-shaped dental instrument worn on the patient's mandibular dentition, and a sagittal retaining device, and when the upper and lower jaws are occluded, the sagittal retaining device sagittally retains the mandible at a predetermined position capable of opening the airway; the limiting portion is located on the side surface of the cavity in the posterior teeth area of ​​the maxillary shell-shaped dental instrument and / or the mandibular shell-shaped dental instrument, and is convexly arranged toward the opposite jaw. Through the arrangement of the limiting portion, when the snoring stopper of the present application is worn, the limiting portion can abut against the side surface of the cavity at the corresponding position of the posterior teeth area of ​​the opposite jaw, thereby limiting the horizontal leftward and horizontal rightward movement of the patient's mandible, and enabling the patient's mandible to be stably maintained at the predetermined position capable of opening the airway, thereby further improving the snoring stopper effect.

[0056] Please see Figures 1 to 4As shown, the anti-snoring device 100 of the present application includes an anti-snoring device body and a limit portion for limiting the horizontal movement of the patient's mandible; the anti-snoring device body includes a maxillary shell-shaped dental appliance 1 worn on the patient's maxillary dentition, a mandibular shell-shaped dental appliance 2 worn on the patient's mandibular dentition, and a sagittal retaining device 3, the maxillary shell-shaped dental appliance 1 and the mandibular shell-shaped dental appliance 2 respectively include a plurality of cavities 10 arranged in a U shape for accommodating a plurality of teeth, when the upper and lower jaws are occluded, the sagittal retaining device 3 sagittally retains the mandible at a predetermined position capable of opening the airway; wherein, the specific structure of the sagittal retaining device 3 is not limited, and any sagittal retaining device 3 capable of sagittally retaining the patient's mandible at a position forward enough to open the airway is acceptable. The limiting part is located on the side surface of the cavity 10 in the posterior teeth area of ​​the maxillary shell-shaped dental instrument 1 or the mandibular shell-shaped dental instrument 2, and is convexly arranged in the direction of the opposite jaw. The limiting part includes a first limiting member 4 and a second limiting member 5. The first limiting member 4 and the second limiting member 5 are respectively against the side surface of the cavity 10 at the corresponding position of the posterior teeth area of ​​the opposite jaw to limit the horizontal leftward and horizontal rightward movement of the lower jaw, so that the lower jaw is kept at the predetermined position. In the present technical scheme, a limiting part for limiting the horizontal leftward and rightward movement of the patient's lower jaw is provided on the snoring stopper body. Specifically, the first limiting member 4 and the second limiting member 5 are respectively against the side surface of the cavity 10 at the corresponding position of the posterior teeth area of ​​the opposite jaw to limit the horizontal leftward and horizontal rightward movement of the lower jaw, so that the patient's lower jaw does not deviate horizontally. In this way, through the horizontal movement restriction and sagittal position maintenance, the patient's lower jaw can be stably maintained at the predetermined position, which is used for stopping snoring and can improve the effect of stopping snoring.

[0057] Please continue to see Figures 1 to 4 As shown in the figure, the first stopper 4 and the second stopper 5 are respectively provided on the left and right sides of the same jaw. It should be noted that the "left" and "right" in this application document are based on the left and right directions presented in the drawings. Figure 1 The first stopper 4 and the second stopper 5 are both located on the lingual surfaces of the cavities 10 on the left and right sides of the posterior teeth area of ​​the mandibular shell-shaped dental instrument 2. More preferably, the first stopper 4 and the second stopper 5 are symmetrically arranged about the tooth midline L. When the first stopper 4 and the second stopper 5 are respectively against the lingual surfaces of the cavities 10 at the corresponding positions of the maxillary posterior teeth area, the paths of the patient's mandible moving horizontally to the left and right are blocked respectively, thereby stably limiting the patient's mandible in the horizontal direction.

[0058] In another embodiment, if Figure 2The first limiting member 4 and the second limiting member 5 shown are both located on the lingual surfaces of the cavities 10 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 4 and the second limiting member 5 are symmetrically arranged about the tooth midline L. When the first limiting member 4 abuts against the lingual surface of the cavity 10 at the corresponding position of the left posterior teeth area of ​​the mandible, the path of the patient's mandible moving horizontally to the right is blocked; when the first limiting member 5 abuts against the lingual surface of the cavity 10 at the corresponding position of the right posterior teeth area of ​​the mandible, the path of the patient's mandible moving horizontally to the left is blocked, thereby stably limiting the patient's mandible in the horizontal direction.

[0059] In another embodiment, if Figure 3 The first limiting member 4 and the second limiting member 5 shown are both located on the buccal surfaces of the cavities 10 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 4 and the second limiting member 5 are symmetrically arranged about the tooth midline L. When the first limiting member 4 abuts against the buccal surface of the cavity 10 at the corresponding position of the left posterior teeth area of ​​the mandible, the first limiting member 4 blocks the horizontal movement path of the patient's mandible to the left; when the second limiting member 5 abuts against the buccal surface of the cavity 10 at the corresponding position of the right posterior teeth area of ​​the mandible, the second limiting member 5 blocks the horizontal movement path of the patient's mandible to the right, thereby stably limiting the patient's mandible in the horizontal direction.

[0060] In another embodiment, if Figure 4 The first limiting member 4 and the second limiting member 5 shown are both located on the buccal surfaces of the cavities 10 on the left and right sides of the posterior teeth area of ​​the mandibular shell-shaped dental instrument 2. More preferably, the first limiting member 4 and the second limiting member 5 are symmetrically arranged about the tooth midline L. When the first limiting member 4 abuts against the buccal surface of the cavity 10 at the corresponding position of the left posterior teeth area of ​​the maxilla, the first limiting member 4 blocks the horizontal rightward movement path of the patient's mandible; when the second limiting member 5 abuts against the buccal surface of the cavity 10 at the corresponding position of the right posterior teeth area of ​​the maxilla, the second limiting member 5 blocks the horizontal leftward movement path of the patient's mandible, thereby stably limiting the patient's mandible in the horizontal direction.

[0061] In the above embodiment, when the first limit member 4 and the second limit member 5 are arranged on the left and right sides of the same jaw, by arranging the first limit member 4 and the second limit member 5 to be symmetrical about the dental midline L, it can be achieved that when the upper and lower jaws are occluded, the force restricting the horizontal movement of the patient's lower jaw from the first limit member 4 and the second limit member 5 is symmetrically distributed in the horizontal direction, so that the horizontal positioning of the left and right sides of the patient's lower jaw is more stable, thereby enabling the patient's lower jaw to be further stably maintained at the predetermined position to enhance the anti-snoring effect.

When the upper and lower jaws are occluded, the corresponding position of the posterior tooth area of ​​the mandibular shell-shaped dental instrument 2 is located between the first limiting member 4 and the second limiting member 5 to limit the horizontal upward movement of the patient's mandible, thereby stably limiting the patient's mandible in the horizontal upward direction.

[0067] In other embodiments, Figures 10 to 12 As shown, it is schematically shown that the first limiting member 4 and the second limiting member 5 are respectively arranged on the buccal surface and the lingual surface of the left side of the maxillary shell-shaped dental instrument 1, the buccal surface and the lingual surface of the right side of the mandibular shell-shaped dental instrument 2, and the buccal surface and the lingual surface of the left side of the mandibular shell-shaped dental instrument 2. When the upper and lower jaws are occluded, the corresponding position of the posterior tooth area of ​​the mandibular shell-shaped dental instrument 2 is located between the first limiting member 4 and the second limiting member 5 to limit the horizontal upward movement of the patient's mandible, thereby stably limiting the patient's mandible in the horizontal direction.

[0068] In one embodiment, especially when the first stopper 4 and the second stopper 5 are arranged on the lingual side of the left and right sides of the same jaw, please continue to refer to Figure 1 and Figure 2The sagittal holding device 3 includes a connecting piece 31 connected to the buccal side of the maxillary shell-shaped dental instrument 1 and the buccal side of the mandibular shell-shaped dental instrument 2; specifically, the buccal side of the maxillary shell-shaped dental instrument 1 is provided with a first connecting portion 32 at the position of the front teeth, and the buccal side of the mandibular shell-shaped dental instrument 2 is provided with a second connecting portion 33 at the position of the back teeth; it can be understood that the first connecting portion 32 can also be provided at the position of the buccal side of the maxillary shell-shaped dental instrument 1 at the position of the back teeth, and the second connecting portion 33 can also be provided at the position of the buccal side of the mandibular shell-shaped dental instrument 2 at the position of the front teeth; the first end 311 of the connecting piece 31 is connected to the maxillary shell-shaped dental instrument 1 through the first connecting portion 32, the The second end 312 of the connecting piece 31 is connected to the mandibular shell-shaped dental instrument 2 through the second connecting portion 33; wherein, the rigidity of the connecting piece 31 is sufficient to keep the patient's mandible in a sagittal position sufficiently forward to open the airway to suppress snoring, and has elasticity to improve the patient's comfort; as described in the background technology, the greater rigidity of the connecting piece 31 is beneficial to maintaining the sagittal position of the patient's mandible, thereby obtaining a better anti-snoring effect, but the greater rigidity directly affects the patient's comfort, such as scratching or even scratching the patient's cheek muscles; therefore, in clinical practice, elastic parts with moderate elasticity are often used to make the connecting piece 31, so as to find a balance between the anti-snoring effect and comfort, so as to stop snoring and improve the patient's comfort.

[0069] In another embodiment, especially when the first stopper 4 and the second stopper 5 are arranged on the buccal sides of the left and right sides of the same jaw, please continue to refer to Figure 3 and Figure 4 The sagittal holding device 3 includes a connecting piece 31 connected to the lingual side of the maxillary shell-shaped dental instrument 1 and the lingual side of the mandibular shell-shaped dental instrument 2; specifically, the maxillary shell-shaped dental instrument 1 is provided with a first connecting portion 32 at the lingual side close to the front teeth, and the mandibular shell-shaped dental instrument 2 is provided with a second connecting portion 33 at the lingual side close to the posterior teeth; it can be understood that the first connecting portion 32 can also be provided at the lingual side of the maxillary shell-shaped dental instrument 1 at the posterior teeth, and the second connecting portion 33 can also be provided at the lingual side of the mandibular shell-shaped dental instrument 2 at the anterior teeth; the first end 311 of the connecting piece 31 is connected to the maxillary shell-shaped dental instrument 1 through the first connecting portion 32, and the second end 312 of the connecting piece 31 is connected to the mandibular shell-shaped dental instrument 2 through the second connecting portion 33; wherein the rigidity of the connecting piece 31 is sufficient to keep the patient's mandible in a sagittal sufficiently forward position to open the airway to suppress snoring, and it is elastic to improve the patient's comfort.

[0070] In one embodiment, the first connection portion 32 includes a first protrusion 321, and the first protrusion 321 protrudes away from the buccal surface of the maxillary shell-shaped dental instrument 1; the first protrusion 321 can be formed integrally with the maxillary shell-shaped dental instrument 1, or the first protrusion 321 can be manufactured separately and then installed at the buccal position of the maxillary shell-shaped dental instrument 1 by bonding or welding. The connecting member 31 includes a hook portion 313 and a straight rod portion 314 which are connected in sequence. The hook portion 313 is arranged at the first end 311 of the connecting member 31 and is hooked and connected with the first protrusion 321 on the same side. The straight rod portion 314 is arranged at the second end 312 of the connecting member 31 and is movably connected to the buccal surface of the mandibular shell-shaped dental instrument 2 through the second connection portion 33. In this way, after the hook portion 313 and the first protrusion 321 are hooked, the patient's mandible can be kept at the predetermined position.

[0071] In one embodiment, see Fig.13 As shown, the hook portion 313 is designed to have an opening structure with an opening toward the posterior tooth area, and the overall shape is a curved hook. Fig.13 The boundary between the hooking part 313 and the straight rod part 314 is not obvious, and the boundary line is indicated by a dotted line, but the structural composition is not limited, that is, the hooking part 313 and the straight rod part 314 can be designed as an integral molding, or can be manufactured separately. The opening structure that is not fully enclosed in this embodiment is conducive to the hooking of the hooking part 313 and the first protrusion 321, and the design of the opening of the hooking part 313 facing backwards avoids the situation that the hooking part 313 falls off in the oral cavity, thereby ensuring its treatment effect and safety in use, because after the hooking, the patient's mandible has a sagittal forward force, and according to the mutual action of force, the connecting member 31 will be subjected to a sagittal backward force, then after the hooking part 313 and the first protrusion 321 are hooked, the hooking part 313 has a backward force relative to the first protrusion 321, then under the action of force, the hooking part 313 will not fall off from the first protrusion 321, which is safer and more reliable.

[0072] In one embodiment, see Fig.14As shown, the hook portion 313 is designed to be an annular structure 316 that can be sleeved on the outer periphery of the first convex column 321. In order not to affect the movable connection of the connecting member 31, the inner contour shape of the annular structure 316 can be consistent with the outer contour shape of the first convex column 321, and the aperture size of the annular structure 316 is slightly larger than the outer contour size of the first convex column 321. With such a design, when the annular structure 316 is sleeved on the outer periphery of the first convex column 321, the first convex column 321 is limited in the front and back of the shape, so that if the patient opens his mouth during sleep, the connecting member 31 will not easily detach from the first convex column 321, thereby increasing the reliability of the connection.

[0073] In one embodiment, see Fig.15 As shown, the straight rod portion 314 rotates around the normal axis Z of the side surface where the second connection portion 33 is located. In the figure, the normal axis of the side surface where the second connection portion 33 is located is indicated by Z, and the side surface where the second connection portion 33 is located is indicated by P. The normal axis Z is perpendicular to the side surface P where the second connection portion 33 is located. This design facilitates the hooking and detaching of the hooking portion 313 of the connecting member 31 and the first protruding column 321 when wearing and removing the anti-snoring device 100 of the present application, and does not interfere with each other when wearing and removing the anti-snoring device 100. Usually, after the patient wears the maxillary shell-shaped dental device 1 and the mandibular shell-shaped dental device 2, the patient first rotates the straight rod portion 314 around the normal axis of the side surface where the second connecting portion 33 is located, so that the hook portion 313 is located at a position convenient for hooking on the first convex column 321, and then hooks or sleeves the hook portion 313 on the first convex column 321; if the patient wants to take it off, the hook portion 313 is first separated from the first convex column 321, and finally the snoring stopper 100 is taken off.

[0074] In one embodiment, see Fig.16As shown, the second connection part 33 includes a second protruding column 331 protruding away from the side surface of the mandibular shell-shaped dental instrument 2, and the free end of the second protruding column 331 is provided with a mounting cap 332 extending in all directions and having a smooth edge, and the outer contour dimension D2 of the mounting cap 332 is larger than the outer contour dimension D1 of the second protruding column 331. The second end 312 of the connecting member 31 is provided with a mounting hole at a corresponding position that can be sleeved on the second protruding column 331, and the inner contour shape of the mounting hole can be consistent with the outer contour shape of the second protruding column 331, and the aperture size of the mounting hole is slightly larger than the outer contour size of the second protruding column 331, so as to facilitate the straight rod part 314 to rotate along the normal axis of the side surface where the second connection part 33 is located. The mounting cap 332 disposed at the free end of the second protrusion 331 has a circular outer edge in a "button" shape, so that after the mounting hole is sleeved on the second protrusion 331, it can be better confined between the side surface of the shell-shaped dental instrument where the second protrusion 331 is located and the mounting cap 332, and is not easy to fall off; moreover, the outer edge of the mounting cap 332 is smooth and round, and it is more comfortable to wear. Furthermore, the mounting cap 332 can be made of elastic material to further improve the comfort of the patient.

[0075] In one embodiment, the first connecting portion 32 and the second connecting portion 33 may be designed to penetrate through the through hole 322 on the buccal surface of the maxillary shell-shaped dental appliance 1 and the mandibular shell-shaped dental appliance 2. Fig.17 As shown, the first connecting portion 32 and the second connecting portion 33 are respectively provided with through holes 322 on the buccal surface of the anterior teeth area of ​​the maxillary shell-shaped dental instrument 1 and the buccal surface of the posterior teeth area of ​​the mandibular shell-shaped dental instrument 2; or in another embodiment, the first connecting portion 32 and the second connecting portion 33 are respectively provided with through holes (not shown) on the buccal surface of the posterior teeth area of ​​the maxillary shell-shaped dental instrument 1 and the buccal surface of the anterior teeth area of ​​the mandibular shell-shaped dental instrument 2; accordingly, the first end 311 and the second end 312 of the connecting member 31 are respectively provided with mounting portions 315 that can pass through the through holes 322, combined with Fig.18 and Fig.19As shown, one end 317 of the mounting portion is connected to the connecting member 31, and the other end 318 of the mounting portion is provided with a third limiting member 319 for limiting the mounting portion 315 from escaping from the through hole 322 along the distal tooth direction Y. When the mounting portion 315 passes through the through hole 322, the third limiting member 319 is clamped with the inner surface of the buccal side of the through hole 322 and does not fall off, wherein the outer contour dimension D3 of the third limiting member 319 is larger than the aperture dimension D4 of the through hole 322, and is used to limit the mounting portion 315 from escaping from the through hole 322 along the distal tooth direction Y. After connection, the first end 311 and the second end 312 of the connecting member 31 can both rotate around the normal axis of the side surface of the cavity 10 where the through hole 322 is located.

[0076] In one embodiment, the third limiting member 319 can be a separate structure from the mounting portion 315, that is, after the mounting portion 315 passes through the through hole 322, the third limiting member 319 is installed on the tongue side of the cavity 10 where the through hole 322 is located at the end of the mounting portion 315 away from the connecting member 31; it can also be an integrally molded structure, for example, when the third limiting member 319 passes through the through hole 322, it can be elastically deformed to pass through the through hole 322, and after passing through the through hole 322, the third limiting member 319 returns to its original shape and is clamped on the inner surface of the cavity 10 where the through hole 322 is located.

[0077] In one embodiment, when the third limiting member 319 can undergo elastic deformation when passing through the through hole 322 so as to pass through the through hole 322, the mounting portion 315 and the connecting member 31 can also be manufactured as one piece; it can be understood that the mounting portion 315 and the connecting member 31 can also be manufactured as separate bodies, and the connecting member 31 and the mounting portion 315 are manufactured separately. After the mounting portion 315 passes through the through hole 322, the end of the mounting portion 315 away from the tooth is installed on the connecting member 31 by a fixing method such as bonding or welding. Alternatively, the connecting member 31 and the mounting portion 315 are designed to be a detachable structure for easy disassembly and replacement, and there is no restriction in the present application.

[0078] In one embodiment, see Fig. 20 and Fig.21As shown, the outer contour dimension of the third limit member 319 near the insertion end is smaller than the aperture dimension of the through hole 322, and the outer contour dimension of the limit member away from the insertion end is larger than the aperture dimension of the through hole 322. When the mounting portion 315 is inserted into the through hole 322, the third limit member 319 is retracted and gathered inward toward the mounting portion 315 under the constraint of the through hole 322, so that the mounting portion 315 passes through the through hole 322 and is clamped with the inner surface of the cavity where the through hole 322 is located, so as to limit the movement of the mounting portion 315 along the distal tooth direction Y.

[0079] In one embodiment, the inner surface of the cavity where the mounting portion 315 is located abuts against the third limiting member 319 accommodated therein so that the third limiting member 319 is accommodated in a predetermined position between the inner surface of the cavity where the through hole 322 is located and the tooth covered by the cavity. The third limiting member 319 includes a guide portion 3191 and a supporting portion 3192 which are sequentially connected, and the guide portion 3191 and the mounting portion 315 are connected; the guide portion 3191 and the mounting portion 315 are arranged at a preset angle α, and the guide portion 3191 cooperates with the through hole 322 to guide the third limiting member 319 to gather inward, wherein the preset angle α is an acute angle between 5 degrees and 80 degrees, and in actual applications it can be between 10 degrees and 60 degrees, or 20 degrees, 30 degrees, etc.; Specifically, because the outer contour dimension of the portion of the guide portion 3191 away from the supporting portion 3192 is smaller than the aperture dimension L of the through hole 322, the portion of the guide portion 3191 away from the supporting portion 3192 is easily inserted into the through hole 322 via the insertion direction. Through the guidance of the guide portion 3191, during the gradual insertion of the third limiting member 319, the portion of the guide portion 3191 near the supporting portion 3192 is elastically compressed and gathered inwardly, that is, gathered toward the mounting portion 315, so as to pass through the through hole 322.

[0080] It can be understood that the above-mentioned resistance means that the third limit member 319 cannot fall out of the through hole 322, and does not mean a completely seamless fit and resistance. The outer contour of the mounting portion 315 and the inner contour of the through hole 322 are also not completely seamless fit. The present application is designed in this way, so that after the snoring stopper 100 is installed, the mounting portion 315 can rotate in the through hole 322, so as to realize the movably connecting the connecting member 31 to the maxillary shell-shaped dental appliance 1 and the mandibular shell-shaped dental appliance 2, so that the patient can open and close his mouth freely while being able to stop snoring.

[0081] In one embodiment, there is a gap 3193 between at least the portion of the guide portion 3191 away from the insertion end and the mounting portion 315 to provide space for the third limiting member 319 to gather toward the mounting portion 315. Specifically, the end of the gap 3193 away from the connection between the guide portion 3191 and the connecting portion is an open structure. It is further defined that there is a gap 3193 between at least the portion of the guide portion 3191 away from the insertion end and the connecting portion to achieve the inward gathering movement of the guide portion 3191. In practical applications, the gap 3193 can be achieved by a groove, such as a V-shaped groove.

[0082] In another embodiment, see Figure 22 to Figure 27 As shown, the sagittal holding device 3 includes a first jaw pad 34 and a second jaw pad 35, wherein the first jaw pad 34 is arranged on the occlusal surface of the posterior teeth area of ​​the maxillary shell-shaped dental instrument 1 and protrudes toward the mandible; the second jaw pad 35 is arranged on the occlusal surface of the posterior teeth area of ​​the mandibular shell-shaped dental instrument 2 and protrudes toward the mandible; and the mesial side of the first jaw pad 34 has an upper guide slope 341 inclined downward toward the mesial side, and the distal side of the second jaw pad 35 has a lower guide slope inclined upward toward the distal side. 351; further explained, the upper guide bevel 341 and the lower guide bevel 351 have the same inclination angle, and contact each other when the patient's upper and lower jaws are occluded. Since the upper guide bevel 341 is inclined forward and downward, and the lower guide bevel 351 is inclined backward and upward, when the patient's face is facing upward during sleep, after the upper and lower guide bevels 351 contact each other, the upper guide bevel 341 is located below the lower guide bevel 351, forming a locking effect, so that the first jaw pad 34 can lock the second jaw pad 35, thereby preventing the mandible from retreating and playing a role in stabilizing the position of the mandible. Such a sagittal retaining device 3 is not limited by the setting positions of the first limit member 4 and the second limit member 5. The first limit member 4 and the second limit member 5 can be simultaneously set on the buccal surface of the same jaw, such as Fig.23 and Fig.24 As shown, the first stopper 4 and the second stopper 5 can be arranged on the buccal side of the patient's lower jaw at the same time; it can be understood that the first stopper 4 and the second stopper 5 can also be arranged on the buccal side of the patient's upper jaw at the same time. They can also be arranged on the lingual surface of the same jaw at the same time, such as Fig.25 As shown, the first stopper 4 and the second stopper 5 can also be arranged on the lingual side of the patient's lower jaw at the same time; it can be understood that the first stopper 4 and the second stopper 5 can also be arranged on the lingual side of the patient's upper jaw at the same time. They can also be arranged on the buccal surface and the lingual surface of the same side of the same jaw, such as Fig.26As shown, the first stopper 4 and the second stopper 5 are simultaneously arranged on the buccal side and the lingual side of the left side of the patient's lower jaw; it can be understood that the first stopper 4 and the second stopper 5 can also be simultaneously arranged on the buccal side and the lingual side of the right side of the patient's lower jaw; or, simultaneously arranged on the buccal side and the lingual side of the left side of the patient's upper jaw; or, simultaneously arranged on the buccal side and the lingual side of the right side of the patient's upper jaw. It can also be arranged on the buccal side and the lingual side of different jaws, such as Fig. 27 As shown, the first limiting member 4 and the second limiting member 5 are respectively arranged on the buccal side of the left posterior teeth area of ​​the patient's maxilla and the lingual side of the right posterior teeth area of ​​the patient's mandibular; it is understandable that the first limiting member 4 and the second limiting member 5 can also be respectively arranged on the buccal side of the right posterior teeth area of ​​the patient's maxilla and the lingual side of the left posterior teeth area of ​​the patient's mandibular; or, the first limiting member 4 and the second limiting member 5 are respectively arranged on the lingual side of the left posterior teeth area of ​​the patient's maxilla and the buccal side of the right posterior teeth area of ​​the patient's mandibular; it is understandable that the first limiting member 4 and the second limiting member 5 can also be respectively arranged on the lingual side of the right posterior teeth area of ​​the patient's maxilla and the buccal side of the left posterior teeth area of ​​the patient's mandibular.

[0083] In one embodiment, please continue to see Fig. 22 As shown, in order to better guide the mandible forward, the angle β between the upper guide slope 341 and the lower guide slope 351 and the tooth jaw plane X is between 40-50 degrees, for example, can be 45 degrees.

[0084] In one embodiment, see Fig.28 As shown, in order to increase the friction between the upper guide bevel 341 and the lower guide bevel 351 when they are in contact, and thus to play a better role in guiding the lower jaw forward, the upper guide bevel 341 and the lower guide bevel 351 can be serrated guide bevels with matching concave and convex surfaces.

[0085] In one embodiment, see Fig.29 and Fig.30 As shown, the width of the first jaw pad 34 gradually narrows from the upper guide bevel 341 to the other end 342, that is, the width of the first jaw pad 34 gradually narrows from the end in contact with the mandibular second jaw pad 35 to the other end 342 in the tongue-cheek direction C, so as to enhance the strength of the first jaw pad 34 against the force from the second jaw pad 35 along the dental arch curve. It is understandable that in order to enhance the strength of the force of the second jaw pad 35 along the dental arch curve, the second jaw pad 35 can also be designed as a structure in which the width gradually narrows from the end in contact with the maxillary first jaw pad 34 (i.e., the position of the lower guide bevel 351) to the other end 352 in the tongue-cheek direction C, which will not be described in detail here.

[0086] In one embodiment, please continue to see Fig. 27As shown, the shape of the side surface 41 of the first limiting member 4 adjacent to the teeth of the opposing jaw or the side surface 51 of the second limiting member 5 adjacent to the teeth of the opposing jaw can be designed to match the concave and convex shape of the side surface of the cavity against which the jaw abuts, or the shape of the side surface 41 of the first limiting member 4 adjacent to the teeth of the opposing jaw and the side surface 51 of the second limiting member 5 adjacent to the teeth of the opposing jaw can both be designed to match the concave and convex shape of the side surface of the cavity against which the jaw abuts; such a design can make the first limiting member 4 or the second limiting member 5 and the corresponding side surface of the cavity of the opposing jaw better fit when they abut, improve the stability when abutting, and increase the comfort of the patient's posterior teeth area.

[0087] In one embodiment, the first limiting member 4 or the second limiting member 5 may be provided with a reinforcement part at the same time, or only one of the limiting members may be provided with a reinforcement part, and the reinforcement part is a strip-shaped structure or a dot-shaped structure protruding or concave toward the tooth direction on the side surface of the first limiting member 4 or the second limiting member 5 adjacent to the opposing teeth. By increasing the surface curvature of the first limiting member 4 or the second limiting member 5, the deformation resistance of the first limiting member 4 or the second limiting member 5 is increased, so that the first limiting member 4 or the second limiting member 5 will not be deformed during use, which affects the limiting effect.

[0088] In one embodiment, the first limiting member 4 protrudes from a first position on the side surface of the cavity where the first limiting member 4 is located toward the opposing jaw, wherein the first position may be at the gums on the side surface of the cavity where the first limiting member 4 is located, may be at a position where the first limiting member 4 covers 1 / 2 of the crown height of the teeth of the present jaw, or may be any position between the gums on the side surface of the cavity where the first limiting member 4 is located and the position where the first limiting member 4 covers 1 / 2 of the crown height of the teeth of the present jaw; protruding from the first position toward the opposing jaw can make the first limiting member 4 less likely to deform when it abuts against the opposing jaw, and is relatively stable, which is conducive to enhancing the limiting effect. For example, in combination with Fig.24 As shown, the first stopper 4 protrudes from the gingival end of the buccal surface of the shell-shaped dental instrument 2 of the patient's mandible to the maxilla; as another example, in combination with Fig.25 As shown, the first stopper 4 protrudes from the lingual surface of the patient's mandibular shell-shaped dental instrument 2 toward the maxilla, and the first position is located at 1 / 2 of the crown height of the tooth covered by the cavity where the first stopper 4 is located. It can be understood that the position where the second stopper 5 protrudes from the second position toward the opposite jaw can be consistent with the protruding position of the first stopper 4, which will not be repeated here.

[0089] In one embodiment, please continue to refer to Fig.24 and Fig.25As shown, the height of the first stopper 4, that is, the height of the first stopper 4 covering the opposing jaw when occluding, in the present application, the height is set as follows: the stopper covers at least the third position of the cavity side surface at the corresponding position of the opposing jaw posterior teeth area, and the third position is between the gums of the cavity side surface at the corresponding position of the opposing jaw posterior teeth area and the 1 / 2 position of the crown height of the opposing jaw teeth covered by it; clinically, it generally cannot be lower than the 1 / 2 position of the crown height of the opposing jaw teeth, otherwise the limiting effect is poor, and the opposing jaw is more likely to slip off the abutment of the first stopper 4, resulting in a failure of limiting. It can be understood that the second stopper 5 covers the fourth position of the opposing jaw, which can be consistent with the design of the first stopper 4, and will not be repeated here.

[0090] In one embodiment, please combine Fig. 27 As shown, in order to improve the wearing comfort and to reduce the foreign body sensation caused by the first limiting member 4 or the second limiting member 5 to the buccal or lingual side of the patient, the thickness h of the first limiting member 4 or the second limiting member 5 in the horizontal direction B should not be too large. In the present application, the thickness h of the first limiting member 4 or the second limiting member 5 in the horizontal direction B is designed to be 1 mm to 3 mm, for example, 2 mm.

[0091] It should be noted that the above embodiments can be freely combined as needed to form different new implementation plans without causing any contradiction. The implementation plans formed after such combination are all within the scope of protection of this application. In order to save the length of the application text, they will not be repeated here.

[0092] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the creative principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present application.

[0093] Similarly, the above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
