Abstract
Description
Technical Field
[0001] This utility model belongs to the field of anti-snoring technology, and more specifically, relates to an adjustable anti-snoring device. Background Technology
[0002] Snoring is a common problem that bothers many people. It is often caused by nasopharyngeal diseases, insufficient muscle tone, or other factors that lead to narrowing of the airway. When airflow passes through the narrowed airway, it causes the surrounding soft tissues to vibrate, producing snoring sounds. Snoring can lead to health problems such as daytime sleepiness, cardiovascular disease, diabetes, and accelerated aging. Currently, common treatments for snoring include lifestyle modifications such as weight loss, sleeping on one's side, and quitting smoking and alcohol; surgical treatments such as tonsillectomy, nasal surgery, and uvulopalatopharyngoplasty; and non-surgical treatments such as continuous positive airway pressure (CPAP) and wearing anti-snoring devices. However, lifestyle modifications are sometimes less effective, surgery carries significant trauma and the risk of complications, and non-surgical treatments such as CPAP are complex and uncomfortable. Anti-snoring devices work by protruding the jaw and pulling the tongue forward to open the airway, reducing or eliminating snoring. However, existing anti-snoring devices have drawbacks such as poor wearing experience, lack of adjustability, limited applicability, and difficulty in addressing individual differences among wearers. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an adjustable anti-snoring device that solves problems such as the inability to adjust, limited applicability, and difficulty in addressing individual differences among wearers.
[0004] To achieve the above objectives, this utility model provides an adjustable anti-snoring device, comprising:
[0005] The mandibular base and the mandibular base are respectively able to be fitted onto the outer side of the upper and lower teeth. The front end of the mandibular base is provided with a mandibular limiting plate. The front end of the maxillary base is connected to a first maxillary limiting plate through a first adjustment mechanism. The first maxillary limiting plate is used to limit the engagement with the mandibular limiting plate. The rear end of the maxillary base is connected to a second maxillary limiting plate through a second adjustment mechanism. The second maxillary limiting plate is used to contact the rear end of the mandibular base. The first adjustment mechanism and the second adjustment mechanism can respectively adjust the first maxillary limiting plate back and forth and adjust the second maxillary limiting plate up and down.
[0006] Optionally, the maxillary base covers the anterior part of the hard palate, the palatal gingival surface of the bilateral maxillary anterior teeth and premolars, the pressing surface of the first molar and the axial surface of the second molar, and is adapted to the shape of the upper teeth.
[0007] Optionally, the mandibular base covers the axial surfaces of both lower teeth and is adapted to the shape of the lower teeth.
[0008] Optionally, the mandibular limiting plate extends upward from the position of the mandibular base inside the lower central incisor and corresponding to the lower canine, forming an upward convex structure.
[0009] Optionally, the first maxillary limiting plate is positioned on the palatal side of the maxillary baseplate via the first adjustment mechanism.
[0010] Optionally, the second maxillary limiting plate is positioned by the second adjustment mechanism at the occlusal position of the maxillary base between the first and second maxillary molars.
[0011] Optionally, the maxillary base, the mandibular base, the mandibular limiting plate, the first maxillary limiting plate, and the second maxillary limiting plate are all made of 3D-printed plastic material.
[0012] Optionally, the first maxillary limiting plate can be adjusted forward and backward within a range of 0-15 mm by the first adjustment mechanism; the second maxillary limiting plate can be adjusted up and down within a range of 0-5 mm by the second adjustment mechanism.
[0013] Optionally, the height of the mandibular limiting plate and the first maxillary limiting plate is 3-5 mm, and the thickness of the second maxillary limiting plate is 0.3-0.6 mm.
[0014] This utility model also provides a method for manufacturing an adjustable anti-snoring device, used to manufacture the above-mentioned adjustable anti-snoring device, comprising:
[0015] Acquire three-dimensional data of the wearer's intraoral maxillary and mandibular surfaces and data on the wearer's centric occlusion;
[0016] Acquire data on the maxillary-mandibular occlusion relationship when the wearer's mandible protrudes forward and the bite is opened by a set distance to ensure unobstructed airflow in the breathing passage;
[0017] The above-mentioned adjustable anti-snoring device is designed based on the three-dimensional data of the wearer's upper and lower jaw surfaces, the wearer's centric occlusion data, and the data of the wearer's upper and lower jaw occlusion when the mandible is protruding and the occlusion is open at a set distance to ensure unobstructed airflow in the breathing passage.
[0018] The components of the adjustable anti-snoring device, as designed above, are printed using a 3D printer.
[0019] This invention provides an adjustable anti-snoring device, the advantages of which are as follows: the adjustable anti-snoring device can be fitted onto the upper and lower teeth respectively through the upper and lower jaw bases. The lower jaw limiting plate, in conjunction with the first upper jaw limiting plate, restricts the position of the lower jaw, keeping it in a protruding state. Simultaneously, the contact between the second upper jaw limiting plate and the lower jaw base adjusts the intermaxillary height, restricting the closure of the oral cavity, thus opening the oral cavity and airway, reducing or preventing snoring. Furthermore, the first adjustment mechanism can adjust the front-to-back position of the first upper jaw limiting plate, thereby adjusting the degree of mandibular protrusion, and the second adjustment mechanism can adjust the vertical position of the second upper jaw limiting plate, adjusting the intermaxillary height, thereby adjusting the degree of opening of the oral cavity and airway. This adjustable anti-snoring device can be adjusted according to the intraoral conditions of different wearers, improving its applicability and wearing comfort.

Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0026] like Figure 1 As shown, this utility model provides an adjustable anti-snoring device, comprising:
[0027] The maxillary base 1 and mandibular base 2 can be fitted onto the outer side of the upper and lower teeth, respectively. The front end of the mandibular base 2 is provided with a mandibular limiting plate 3. The front end of the maxillary base 1 is connected to a first maxillary limiting plate 5 through a first adjustment mechanism 4. The first maxillary limiting plate 5 is used to limit the fit with the mandibular limiting plate 3. The rear end of the maxillary base 1 is connected to a second maxillary limiting plate 7 through a second adjustment mechanism 6. The second maxillary limiting plate 7 is used to contact the rear end of the mandibular base 2. The first adjustment mechanism 4 and the second adjustment mechanism 6 can adjust the first maxillary limiting plate 5 back and forth and adjust the second maxillary limiting plate 7 up and down, respectively.
[0028] Specifically, to address the problems of existing anti-snoring devices being non-adjustable, having limited applicability, and being unable to accommodate individual differences among wearers, this utility model provides an adjustable anti-snoring device. The upper jaw base 1 and lower jaw base 2 are respectively fitted onto the upper and lower teeth. The lower jaw limiting plate 3, in conjunction with the first upper jaw limiting plate 5, restricts the position of the lower jaw, keeping it in a protruding state. Simultaneously, the contact between the second upper jaw limiting plate 7 and the lower jaw base 2 adjusts the intermaxillary height, restricting oral closure and opening the oral cavity and airway, reducing or preventing snoring. Furthermore, the first adjustment mechanism 4 adjusts the front-to-back position of the first upper jaw limiting plate 5, thereby adjusting the degree of mandibular protrusion. The second adjustment mechanism 6 adjusts the vertical position of the second upper jaw limiting plate 7, adjusting the intermaxillary height and thus the degree of opening of the oral cavity and airway. This adjustable anti-snoring device can be adjusted according to the intraoral conditions of different wearers, improving its applicability and wearing comfort.
[0029] Optionally, the maxillary base 1 covers the anterior part of the hard palate, the palatal gingival portion of the bilateral maxillary anterior teeth and premolars, the pressing axial surface of the first molar and the axial surface of the second molar, and is adapted to the shape of the upper teeth.
[0030] Specifically, the upper side of the maxillary base 1 is provided with a first wearing groove, which accommodates the wearer's upper teeth and is fitted onto the upper teeth. Through the adaptation of the groove wall of the first wearing groove to the shape of the upper teeth, this design can achieve a precise match between the base and the shape of soft and hard tissues, ensuring adhesion and guaranteeing wearing stability and comfort while minimizing the base area.
[0031] In this embodiment, the anterior part of the maxillary base 1 covers the anterior third of the hard palate, the palatal gingival half of the axial surface of the bilateral maxillary anterior teeth and premolars, and extends posteriorly to the axial surface of the first molar and the second molar, conforming to the shape of the tooth.
[0032] Optionally, the mandibular base 2 covers the axial surfaces of both mandibular teeth and is adapted to the shape of the mandibular teeth.
[0033] Specifically, the lower side of the mandibular base 2 is provided with a second wearing groove, which accommodates the wearer's lower teeth and is fitted onto the lower teeth. Through the adaptation of the groove wall of the second wearing groove to the shape of the lower teeth, this design can achieve a precise match between the base and the shape of soft and hard tissues, ensuring adhesion, stability and comfort of wearing while minimizing the base area.
[0034] In this embodiment, the mandibular base 2 covers the axial surfaces of both lower teeth and conforms to the shape of the tooth.
[0035] Optionally, the mandibular limiting plate 3 extends upward from the mandibular base 2, which is located inside the lower central incisor and corresponding to the lower canine, forming an upward convex structure.
[0036] Specifically, when the wearer wears the maxillary base 1 and the mandibular base 2, the mandibular limiting plate 3 extends towards the maxillary base 1, forming a protruding structure extending upwards from the mandibular base 2. This structure engages with the first maxillary limiting plate 5 to maintain the wearer's mandible in a forward-protruding state. Precise and varied limiting positions allow the patient's mandible to protrude at different locations, thereby controlling ventilation and ensuring normal breathing.
[0037] In this embodiment, the mandibular limiting plate 3 and the mandibular base 2 are fixedly connected on the lingual side of the lower central incisor, at the level of the lower canine.
[0038] Optionally, the first maxillary limiting plate 5 is positioned on the palatal side of the maxillary base 1 via the first adjustment mechanism 4.
[0039] Specifically, when the wearer wears the maxillary base 1 and the mandibular base 2, the first maxillary limiting plate 5 is located behind the mandibular limiting plate 3. Its front surface fits and limits the mandible by adhering to the rear surface of the mandibular limiting plate 3, thus maintaining the mandible in a protruding state. The first adjustment mechanism 4 adjusts the front and back of the first maxillary limiting plate 5, which can indirectly adjust the front and back positions of the mandibular limiting plate 3 and the mandibular base 2, thereby ensuring that the wearer can achieve a good anti-snoring effect while maintaining wearing comfort according to the individual situation of the wearer.
[0040] In this embodiment, the maxillary base 1 is connected to the first maxillary limiting plate 5 on the palatal side of the upper central incisor via the first adjustment mechanism 4.
[0041] Optionally, the first adjustment mechanism 4 can adopt a sliding, threaded, or multiple slotted structure. The threaded structure may include a groove on the maxillary base 1, with the upper end of the first maxillary limiting plate 5 slidably disposed within the groove. A sliding rod is disposed within the groove, sliding through a sliding hole in the first maxillary limiting plate 5. Multiple outwardly protruding elastic parts, such as springs or balls connected to springs, are provided along the axial direction on the outer side of the sliding rod. The wall of the sliding hole in the first maxillary limiting plate 5 is provided with grooves that mate with the elastic parts. The textured structure may include a guide groove provided on the maxillary base 1, the upper end of the first maxillary limiting plate 5 being slidably disposed in the guide groove, a threaded rod being provided in the guide groove, and an operating part being provided on the threaded rod to rotate the threaded rod. The threaded rod passes through the threaded hole of the first maxillary limiting plate 5, and the first maxillary limiting plate 5 can be moved by rotating the threaded rod. The multiple slotted structure may include multiple slots arranged in sequence front and back on the maxillary base 1, and the upper end of the first maxillary limiting plate 5 is inserted into the slots.
[0042] Optionally, the second maxillary limiting plate 7 is positioned by the second adjustment mechanism 6 at the occlusal position of the maxillary base 1 between the first and second maxillary molars.
[0043] Specifically, when the wearer wears the maxillary base 1 and the mandibular base 2, the second maxillary limiting plate 7 is located below the maxillary base 1 and above the mandibular base 2. Its lower surface contacts and limits the mandibular base 2, adjusting the height between the jaws and keeping the oral cavity and airway open. The second adjustment mechanism 6 adjusts the vertical position of the second maxillary limiting plate 7, which can adjust the downward opening of the mandible, thereby ensuring that the wearer can achieve a good anti-snoring effect while maintaining wearing comfort according to the individual wearer's situation.
[0044] In this embodiment, the maxillary base plate 1 is connected to the second maxillary limiting plate 7 via the second adjustment mechanism 6 on the occlusal surfaces of the first and second molars.
[0045] Optionally, the second adjustment mechanism 6 can adopt a sliding, threaded, or multiple rods of different lengths structure. The sliding structure can include a groove on the maxillary base 1, a sliding rod on the upper side of the second maxillary limiting plate 7, the sliding rod can be inserted into the groove, and multiple outwardly protruding elastic parts, such as springs or balls connected to springs, are provided on the outer side of the sliding rod along its axial direction. The groove wall is provided with a groove that does not match the elasticity. The threaded structure can include a threaded hole on the lower side of the maxillary base 1, a threaded rod rotatably connected to the upper side of the second maxillary limiting plate 7, an operating part on the threaded rod for turning the threaded rod to rotate, the threaded rod passing through the threaded hole, and the second maxillary limiting plate 7 can be moved by rotating the threaded rod. The multiple rods of different lengths structure can include multiple rods detachably connected to the second maxillary limiting plate 7, the multiple rods having different lengths, and a slot on the lower side of the maxillary base 1. By inserting rods of different lengths into the slot, the installation height of the second maxillary limiting plate 7 can be different.
[0046] Optionally, the maxillary base 1, mandibular base 2, mandibular limiting plate 3, first maxillary limiting plate 5, and second maxillary limiting plate 7 are all made of 3D-printed plastic material.
[0047] Specifically, 3D-printed plastic materials have excellent properties such as good biocompatibility, high fatigue resistance and toughness, and high dimensional accuracy of the finished products. 3D printing can be used to manufacture adjustable antisnoring device components such as maxillary base 1, mandibular base 2, mandibular limiting plate 3, first maxillary limiting plate 5, and second maxillary limiting plate 7. The process is convenient, fast, and inexpensive, making it suitable for clinical promotion.
[0048] In this embodiment, the plasticizing material used for 3D printing is ABS.
[0049] Optionally, the first maxillary limiting plate 5 can be adjusted forward and backward by the first adjusting mechanism 4 within a range of 0-15mm; the second maxillary limiting plate 7 can be adjusted up and down by the second adjusting mechanism 6 within a range of 0-5mm.
[0050] Specifically, the first maxillary limiting plate 5 moves forward from the rearmost position of the first adjusting mechanism 4, with a range of movement of 0-15mm. The further the first maxillary limiting plate 5 is adjusted forward, the greater the mandibular protrusion. The second maxillary limiting plate 7 moves downward from the uppermost position of the second adjusting mechanism 6, with a range of movement of 0-5mm. The further the second maxillary limiting plate 7 is adjusted downward, the greater the intermaxillary height.
[0051] In this embodiment, the thickness of the maxillary base 1 and the mandibular base 2 is 0.3-0.6 mm.
[0052] Optionally, the height of the mandibular limiting plate 3 and the first maxillary limiting plate 5 is 3-5 mm, and the thickness of the second maxillary limiting plate 7 is 0.3-0.6 mm.
[0053] The manufacturing method of the adjustable anti-snoring device provided by this utility model includes:
[0054] Acquire three-dimensional data of the wearer's intraoral maxillary and mandibular surfaces and data on the wearer's centric occlusion;
[0055] Acquire data on the maxillary-mandibular occlusion relationship when the wearer's mandible protrudes forward and the bite is opened by a set distance to ensure unobstructed airflow in the breathing passage;
[0056] The above-mentioned adjustable anti-snoring device is designed based on the three-dimensional data of the wearer's upper and lower jaw surfaces, the wearer's centric occlusion data, and the data of the wearer's upper and lower jaw occlusion when the mandible is protruding and the occlusion is open at a set distance to ensure unobstructed airflow in the breathing passage.
[0057] The components of the adjustable anti-snoring device, as designed above, are printed using a 3D printer.
[0058] Specifically, in manufacturing the aforementioned adjustable anti-snoring device, firstly, three-dimensional data of the wearer's upper and lower jaw surfaces are scanned, along with data on the wearer's centric occlusion. Then, the wearer's mandible is protruded while the occlusion is opened by 2-5mm to check if the airflow in the wearer's airway is unobstructed. Data on the mandibular occlusion when the airflow in the wearer's airway is unobstructed is scanned, i.e., protrusion occlusion data. Next, the three-dimensional data of the wearer's upper and lower jaw surfaces, centric occlusion data, and protrusion occlusion data are imported into design software, such as RapidForm or Medical Design Studio. The thickness, anterior-posterior, and posterior-inferior adjustment range parameters are set and adjusted according to the wearer's condition. Data for a 3D-printed adjustable anti-snoring device is generated, and its components are printed using a 3D printer. Finally, the adjustable anti-snoring device is assembled.
[0059] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
