Description

  The present invention relates to a system for providing a mouthpiece for raising a hyoid bone.

  Obstructive sleep apnea syndrome (OSAS) is a disease in which the upper airway of a patient is obstructed during sleep and breathing is stopped. Obstructive sleep apnea syndrome has been shown to lead to a worsening of the prognosis of life due to a remarkable decrease in arterial blood oxygen saturation, through an increase in blood pressure, complications of arrhythmias and promotion of arteriosclerosis. In addition, obstructive sleep apnea syndrome causes insomnia and daytime hypersomnia due to an awakening reaction accompanying apnea, but also impairs attention, cognition, memory, etc. And work accidents. For this reason, obstructive sleep apnea syndrome is a major social problem.

  The present inventor has found that the position of the hyoid bone, particularly the position of the body of the hyoid bone, in a lateral head and neck X-ray standard photograph taken of a patient diagnosed with obstructive sleep apnea syndrome and a subject without respiratory disorders Analysis revealed that the position of the center of the body of the hyoid bone was clearly different between the two, and based on this finding, the subject was objectively and at risk of developing obstructive sleep apnea syndrome. There has been proposed a method for determining the risk of obstructive sleep apnea syndrome, which can be easily determined in a short time (see Patent Document 1). According to this risk determination method, at least the hyoid bone, Sera S, gonion Go and Menton Me detected by the lateral head and neck radiography of the subject are used, and the center of the body of the detected hyoid bone is shifted from Me. The risk of obstructive sleep apnea syndrome is determined by determining whether or not it is included in a region above a perpendicular line drawn down from the extension of the line segment S-Go. As a method of reducing this risk, when it is determined that the detected center of the body of the hyoid bone is not included in the region above the perpendicular drawn from Me to the extension of the line segment S-Go. A central occlusion when the center of the body of the hyoid bone is included in a region above a perpendicular drawn from Me to an extension of the line segment S-Go due to the forward movement of the lower jaw with respect to the upper jaw of the subject. The amount of forward movement of the lower jaw relative to the position is determined, and the amount of forward displacement of the lower jaw relative to the upper jaw relative to the distance δ between the upper anterior tooth and the lower anterior tooth at the central occlusal position of the subject is expressed as Δ + δ. It was decided to manufacture an intraoral device, and it was proposed that a patient wear this intraoral device (see Patent Document 2).

  On the other hand, as a treatment method for patients diagnosed with obstructive sleep apnea syndrome, there is a method of expanding the upper respiratory tract by wearing an intraoral device, which is considered to be somewhat effective for mild and moderate patients. . This intraoral device is manufactured such that the lower jaw is displaced forward with respect to the upper jaw (for example, see Non-Patent Document 1).

  However, both the conventional general intraoral device described in Non-Patent Document 1 and the intraoral device described in Patent Document 2 require a certain amount of forward displacement of the lower jaw with respect to the upper jaw. Not only does it place a heavy burden on the whole, but it is extremely difficult for conventional general intraoral devices to be tailored to the patient.

  In order to solve such a problem, although it is not a known technique, the present inventor has disclosed in Japanese Patent Application No. 2019-87330 that the upper jaw is lower than the upper jaw like an intraoral device known so far. The tongue can raise the user's hyoid bone without displacing the tongue forward, and thus without burdening the user, thereby improving the symptoms of obstructive sleep apnea syndrome A bonepiece mouthpiece and a method of manufacturing the same have been proposed.

  Here, in the above invention, the vertical inter-jaw distance is also referred to as an occlusal height.

  The resin sheet constituting the hyoid bone lifting mouthpiece preferably has an inner layer made of a hard synthetic resin, which comes into contact with the dentition, and an outer layer made of a soft synthetic resin outside the inner layer. Accordingly, between the inner layer and the outer layer, for example, one or more layers of a synthetic resin having a hardness between the hardness of the hard synthetic resin forming the inner layer and the hardness of the soft synthetic resin forming the outer layer May be provided. Typically, the resin sheet that constitutes the mouthpiece for raising the hyoid bone is composed of an inner layer and an outer layer. The thickness of the inner layer is 0.3 mm or more and 0.7 mm or less, and the thickness of the outer layer is 1.7 mm or more. 3 mm or less, or the thickness of the inner layer is 0.4 mm or more and 0.6 mm or less, and the thickness of the outer layer is 2.1 mm or more and 3 mm or less. Typically, the hyoid bone lifting mouthpiece is configured such that the vertical intermaxillary distance of the user is increased by 2.3 mm or more and 3.7 mm or less.

  In the present invention, typically, the member informs the reception center of the user's tooth profile in addition to the head and neck radiographed image obtained by the lateral head and neck radiography at the user's central occlusion. The gypsum model is sent by post, courier service, or the like, or three-dimensional coordinate data of the user's dentition is sent by communication.

  At the reception center, there are several methods for producing a hyoid bone elevating mouthpiece desired for the user based on the head and neck photographed images stored in the server and providing the mouthpiece to members. For example, the thickness of the resin sheet is determined within the range of 2 mm or more and 4 mm or less based on the head and neck photographed images stored in the server, and a mouthpiece for raising the hyoid bone is prepared and provided to the member. The member sends to the reception center a head and neck image obtained by lateral head and neck X-ray taken with the user wearing the provided mouthpiece for raising the hyoid bone, and the reception center receives it The captured head and neck images are stored in the server. Then, at the reception center, the suitability of the hyoid bone lifting mouthpiece is determined based on the head and neck photographed images thus accumulated in the server. If the mouthpiece for raising the hyoid bone is judged to be appropriate, the member is notified to that effect. If the tongue lifting mouthpiece is judged to be inappropriate, inform the member to that effect, determine the thickness of the resin sheet to another thickness in the range of 2 mm to 4 mm, and again, Create a mouthpiece for raising the hyoid bone and provide it to members. Then, the member sends a reception image of the head and neck image obtained by the lateral head and neck X-ray imaging performed with the user wearing the provided hyoid bone mouthpiece again to the reception center, and receiving it. The center stores the received head and neck photographed image in the server, and determines whether the mouthpiece for lifting the hyoid bone is appropriate at the reception center based on the head and neck photographed image thus stored in the server. Repeat until the desired hyoid bone lifting mouthpiece is obtained. The above-described method can provide a member with a hypnotic elevating mouthpiece that is desirable for a user to a member. There is a way. That is, in the reception center, based on the head and neck photographed images stored in the server, the thickness of the resin sheet is changed in a plurality of steps within a range of 2 mm or more and 4 mm or less to produce a plurality of mouthpieces for raising the hyoid bone. Provide to members. In this case, the user sequentially wears the plurality of hyoid bone lifting mouthpieces prepared by changing the thickness of the resin sheet in a range of 2 mm or more and 4 mm or less at the reception center. The reception center sends a plurality of head and neck radiographs obtained by the lateral head and neck radiography performed in the state, and the reception center stores the received plurality of head and neck radiographs in the server. Then, at the reception center, based on the plurality of head and neck photographed images stored in the server, the most appropriate mouthpiece for raising the hyoid bone is selected from a plurality of mouthpieces for raising the hyoid bone, and the result is provided to the member. send. The optimal hyoid bone lifting mouthpiece is typically, but not limited to, the largest hyoid bone elevation of the multiple hyoid bone lifting mouthpieces .

  Typically, members communicate by e-mail with a reception center. The reception center typically operates a homepage. This home page is configured to be browsed by members, but may be browsed by non-members. Members are typically dentists, dental clinics, doctors, hospitals, and the like.

In the reception center, there are various methods for producing the hyoid bone elevating mouthpiece based on the head and neck photographed images stored in the server, and the method is selected as necessary from these methods. In one method, a mouthpiece for raising the hyoid bone is prepared by forming a flat resin sheet having a predetermined thickness in close contact with a plaster model of the dentition while applying heat and pressure. According to another method, a mouthpiece for raising the hyoid bone is manufactured by molding a resin to a predetermined thickness by a 3D printer using the three-dimensional coordinate data of the dentition. On the other hand, when the thickness of the resin sheet is not determined in advance, there is the following method as a method of manufacturing a mouthpiece for raising the hyoid bone desired by the user. That is, in one method, using the hyoid bone, Sera S, gonion Go and Menton Me detected by the lateral head and neck radiograph in the central occlusion position of the user, the body part of the hyoid bone detected above is used. The determination device determines whether or not the center of is included in a region above the perpendicular drawn from Me to the extension of the line segment S-Go, and the center of the detected body of the hyoid bone is shifted from Me to the line If it is determined that the distance is not included in the region above the perpendicular drawn down from the extension of the segment S-Go, the center of the body of the hyoid bone is shifted from Me by the line segment S due to the increase in the vertical intermaxillary distance of the user. -To be included in the area above the perpendicular drawn down from the extension line of Go, or to increase the vertical intermaxillary distance Δ when approaching the area, determine the user's upper or lower dentition. Using a 3D printer to increase the vertical jaw distance by Δ using 3D coordinate data A mouthpiece for raising the hyoid bone is manufactured. In another method, the hyoid bone, sera S, gonion Go, menton Me and condillion Cd detected by lateral head and neck radiography in the central occlusion position of the user are used to detect the body of the hyoid bone. The center of the part is in the region above the perpendicular drawn from Me to the extension of the segment S-Go, the perpendicular drawn from Me to the extension of the segment S-Go, and the extension of the segment Cd-Go from Me. The determination device determines which of the region between the vertical line drawn down and the region below the vertical line drawn down from Me the extension of the line segment Cd-Go is included in the determination device, When it is determined that the center of the body part is included in the region between the perpendicular drawn from Me to the extension of the segment S-Go and the perpendicular drawn from Me to the extension of the segment Cd-Go, Due to the increase in the vertical intermaxillary distance of the user, the center of the body of the hyoid bone is now included in the region above the perpendicular line to the extension of the line segment S-Go from e, or, when approaching the area, the increase delta ₁ between the vertical jaw distance determined, the detected above When it is determined that the center of the body of the hyoid bone is included in a region below a perpendicular line drawn from Me to an extension of the line segment Cd-Go, the tongue is increased due to an increase in the vertical intermaxillary distance of the user. A region in which the center of the body of the bone is between a perpendicular line drawn from Me to an extension of the line segment S-Go and a perpendicular line drawn from Me to an extension of the line segment Cd-Go, or a line segment S-Go from Me. Or included in the area above the perpendicular drawn down from the extension of Me, or the perpendicular drawn down from Me to the extension of the segment S-Go, and the perpendicular dropped down from Me to the extension of the segment Cd-Go. when approaching the area between the determined increment delta ₂ between the vertical jaw distance, maxillary user or Others to produce a mouthpiece for the upper hyoid bone elevation as the distance between the vertical jaws increases delta ₁ or delta ₂ by 3D printer using three-dimensional coordinate data of the dentition of the lower jaw. The method of obtaining the three-dimensional coordinate data of the upper or lower dentition of the user is not particularly limited. For example, a plaster model of the upper or lower dentition of the user is prepared, and the plaster model is measured by a three-dimensional measuring device. Measure, obtain a three-dimensional image of the upper or lower jaw from a photographed image of the user's upper or lower jaw from at least two directions with a camera, or use a 3D scanner to read the upper or lower jaw by a 3D scanner , And three-dimensional image data is obtained to obtain three-dimensional coordinate data.

  Here, S, Go, Me, and Cd are measurement points obtained by lateral head and neck radiography, especially head radiography. FIG. 22 shows the position of each measurement point. S is an abbreviation for Sella, which is the center point of the pot-shaped shadow image of the sphenoid turkey saddle. Go is an abbreviation of Gonion, and the bisector of the angle where the line connecting the posterior margin of the temporomandibular joint head and the posterior edge of the mandibular angle intersects the mandibular plane intersects the mandibular angle Is a point. Me is an abbreviation for menton, and is the lowest point in the midline cross-sectional image of the genius. Cd is the highest point (condylion) of the condyle.

  According to the present invention, when the user wears the upper or lower jaw to cover the dentition, the vertical intermaxillary distance is increased by 2 mm or more and 4 mm or less, so that the hyoid bone can be raised. Before the attachment, if the center of the body of the hyoid bone is included in a region below a perpendicular line drawn down from Me to an extension of the line segment S-Go, the center of the body of the hyoid bone is separated from the line segment S from Me. -It can be included in the area above the perpendicular drawn down from the extension line of Go, not only can improve the symptoms of obstructive sleep apnea syndrome of the user, but also can be worn by the user. It is possible to provide a tongue-elevating mouthpiece that does not impose a burden on members, including members located at remote locations.

Then, at the reception center 103, the plurality of hyoid bone lifting mouthpieces 10 are ranked in the order of the height of the hyoid bone based on the plurality of head and neck photographed images stored in the server 102a in this way, and the recommended order is determined. Decide. For example, the hyoid bone lifting mouthpiece 10 having the largest lifting amount of the hyoid bone can be set as the optimal one having the first recommended rank. The result is notified to the member 101. By this communication, the member 101 can determine the hyoid bone lifting mouthpiece 10 to be used by the user. This notification is transmitted to the member 101, for example, attached to an e-mail as an attached file. Alternatively, the reception center 103 sends an e-mail notifying that the candidate of the hyoid bone elevating mouthpiece 10 to be used by the member 101 has been determined, instead of attaching this notification to the e-mail as an attached file, The member 101 may be able to access information previously stored in the server 102a or the cloud server by clicking the URL indicated in the e-mail. If necessary, the user may use a plurality of hyoid bone lifting mouthpieces 10 in the recommended order in which the hyoid height is relatively large. Since the wearing feeling is slightly different depending on the thickness of the resin sheet used for the hyoid bone lifting mouthpiece 10, even when the user desires a better wearing feeling even if the hyoid bone lifting amount is not the maximum. Because there is.

  A method for manufacturing the hyoid bone lifting mouthpiece 10 will be described.

  FIG. 7 shows a first example of a mouthpiece manufacturing apparatus for raising the hyoid bone.

  As shown in FIG. 7, in this mouthpiece manufacturing apparatus for raising a hyoid bone, a stage 60 is provided on the upper surface of a rectangular parallelepiped housing (not shown) containing a vacuum pump and the like. A gypsum model 70 of the tooth shape of the user of the mouthpiece 10 for lifting the hyoid bone is placed on the stage 60. A large number of suction holes (not shown) for vacuum suction are provided in a predetermined arrangement at the center of the stage 60 where the gypsum model 70 is placed. By operating a vacuum pump built in the housing, vacuum suction can be performed from these suction holes. Above the stage 60, a pair of upper and lower square sheet fixing members 81, 82 are provided in parallel with the stage 60 so as to be able to move up and down. For example, openings are provided at the four corners of the sheet fixtures 81 and 82, and four pillars erected to the stage 60 are passed through the openings at the four corners of the stage 60, and these pillars are The seat fixtures 81 and 82 are configured to be able to move up and down along with a conventionally known driving mechanism using a manual or motor. These sheet fixing devices 81 and 82 can be moved up and down independently of each other, so that the distance between them can be changed. These sheet fixing members 81 and 82 can be fixed to each other. A synthetic resin sheet 90 used for manufacturing the hyoid bone lifting mouthpiece 10 is sandwiched between the sheet fixing devices 81 and 82. At the center of the seat fixtures 81 and 82, square openings 81a and 82a having the same size as each other are provided. The size of the openings 81 a and 82 a is selected to be smaller than the synthetic resin sheet 90 to be used and sufficiently larger than the gypsum model 70. The heating device 100 is provided at a position higher than the sheet fixtures 81 and 82 so as to be able to move up and down with respect to the stage 60 integrally with the sheet fixtures 81 and 82 or independently. The heating device 100 is for heating and softening the synthetic resin sheet 90, and is not particularly limited as long as the synthetic resin sheet 90 can be heated, and examples thereof include an electric heater and a lamp heater.

  In order to sandwich the synthetic resin sheet 90 between the sheet fixing tools 81 and 82, a gap is formed by separating the sheet fixing tools 81 and 82 from each other, and the synthetic resin sheet 90 is inserted into the gap from the horizontal direction to open the opening 81a. After the synthetic resin sheet 90 is placed on the sheet fixing device 81 so as to cover the peripheral portion of the synthetic resin sheet 90 by bringing the sheet fixing devices 81 and 82 close to each other, the sheet fixing devices 81 and 82 are held in this state. Secure to each other.

  The hyoid bone lifting mouthpiece 10 is manufactured using the hyoid bone lifting mouthpiece manufacturing apparatus as follows. Here, as an example, a case of manufacturing a maxillary dentition-mounted hyoid bone lifting mouthpiece 10 will be described.

  First, an impression of a user is obtained, and as shown in FIG. 8, a plaster model 70 of an upper dentition is produced, and a hard synthetic resin sheet 91 for forming the inner layer 11 and an outer layer 12 are formed. A synthetic resin sheet 90 having a two-layer structure in which the soft synthetic resin sheet 92 of FIG. The thickness of the synthetic resin sheet 90 is selected to be equal to the increase amount of the vertical intermaxillary distance by the mouthpiece 10 for raising the hyoid bone by a method described later.

  Next, as shown in FIG. 7, the synthetic resin sheet 90 is sandwiched between sheet fixing members 81 and 82.

  Next, the synthetic resin sheet 90 is heated and softened by the heating device 100. In this state, the sheet fixtures 81 and 82 sandwiching the synthetic resin sheet 90 are gradually lowered. Then, the synthetic resin sheet 90 hits the gypsum model 70, and when further lowered, the softened synthetic resin sheet 90 is deformed to conform to the surface of the gypsum model 70. When the operation of the vacuum pump built in the housing is started when the lower surface of the sheet fixture 81 comes into contact with the stage 60, the stage 60, the synthetic resin sheet 90, and the sheet fixture 81 are passed through suction holes provided in the stage 60. Vacuum suction is performed in a space surrounded by the side surface of the opening 81a, and the synthetic resin sheet 90 is strongly pressed against the gypsum model 70 due to the pressure difference generated thereby. This state is shown in FIG. At this time, the synthetic resin sheet 90 is deformed so as to follow the tooth shape of the gypsum model 70 because it is softened.

  Thereafter, the gypsum model 70 together with the synthetic resin sheet 90 is taken out of the hyoid bone lifting mouthpiece manufacturing apparatus, and after removing the synthetic resin sheet 90 from the gypsum model 70, the synthetic resin sheet 90 is formed into a mouthpiece shape.

  As described above, the desired mouthpiece 10 for hyoid bone elevation is manufactured.

  Here, a method of determining the amount of increase in the vertical inter-chin distance (thickness of the synthetic resin sheet 90) by the hyoid bone lifting mouthpiece 10 will be described.

  First, the thickness of the synthetic resin sheet 90 is changed in several steps within a predetermined range, for example, in a range of 2.0 mm or more and 4 mm or less, and the hyoid bone lifting mouthpiece 10 is manufactured by the above-described method. For example, the thickness of the synthetic resin sheet 90 is changed to 2.5 mm, 3.0 mm, 3.5 mm, and 4.0 mm to produce the hyoid bone lifting mouthpiece 10.

  First, in a state where the mouthpiece 10 for lifting the hyoid bone is not worn, a lateral head and neck X-ray is taken at the center occlusion of the user. The imaging is performed by setting the inclination of the head in the front-rear direction such that the Frankfurt plane of the subject's head is parallel to the floor surface. Hyoid bone, sera S, gonion Go and Menton Me are detected by lateral head and neck radiography. The position of the center of the body of the hyoid bone thus detected is determined with respect to a perpendicular line drawn from Me to an extension of the line segment S-Go. As an example, it is assumed that the detected center of the body of the hyoid bone is included in a region below a perpendicular line drawn from Me to an extension of the line segment S-Go. Next, a lateral head and neck X-ray is taken in the same manner with the mouthpieces 10 for hyoid bone elevation prepared by changing the thickness of the synthetic resin sheet 90 being sequentially attached. Then, the change of the center of the body of the hyoid bone is examined for each of the mouthpieces 10 for raising the hyoid bone. From the result, the hyoid bone lifting mouthpiece 10 in which the center of the body of the hyoid bone is included in an area above a perpendicular drawn from Me to an extension of the line segment S-Go, or the area concerned Is selected from the mouthpieces 10 for raising the hyoid bone that are not included in the area and approach the area, and one of the mouthpieces 10 for raising the hyoid bone that has the highest lifting amount of the hyoid bone, or is raised. Select multiple items from the one with the largest amount to the one with a certain amount of lift. The thickness of the synthetic resin sheet 90 used for manufacturing the hyoid bone lifting mouthpiece 10 thus selected is the amount of increase in the required vertical inter-chin distance.

  Alternatively, first, a lateral head and neck X-ray is taken at the central occlusal position of the user without wearing the mouthpiece 10 for raising the hyoid bone, and the hyoid bone, sera S, gonion Go, menton Me and condillion Cd are taken. Is detected. The center of the body of the hyoid bone thus detected is checked with respect to a perpendicular line drawn from Me to an extension of the line segment S-Go or a perpendicular line drawn from Me to an extension of the line segment Cd-Go. As an example, it is assumed that the detected center of the body of the hyoid bone is included in a region below a perpendicular line drawn from Me to an extension of the line segment Cd-Go. Next, a lateral head and neck X-ray is taken in the same manner with the mouthpieces 10 for hyoid bone elevation prepared by changing the thickness of the synthetic resin sheet 90 being sequentially attached. Then, the change of the center of the body of the hyoid bone is examined for each of the mouthpieces 10 for raising the hyoid bone. From the results, the center of the body of the hyoid bone was defined as a region between the perpendicular line drawn from Me to the extension of the line segment S-Go and the perpendicular line drawn from Me to the extension of the line segment Cd-Go, or from the region Me. Mouthpiece 10 for raising the hyoid bone which is included in the area above the perpendicular drawn down to the extension of the line S-Go, or the extension of the line S-Go from Me even if it is not included in these areas The hyoid bone lifting mouthpiece 10 approaching the area between the perpendicular drawn down to the line and the perpendicular drawn down from Me to the extension of the line segment Cd-Go is selected, and in these mouthpieces 10 for lifting the hyoid bone. From the list, select one with the largest lifting amount of the hyoid bone, or select one from the largest lifting amount to the one with a relatively large lifting amount. The thickness of the synthetic resin sheet 90 used for manufacturing the hyoid bone lifting mouthpiece 10 thus selected is the amount of increase in the required vertical inter-chin distance.

  Detection of the center of the body of the hyoid bone, S, Go, Me, and Cd can be performed in the same manner as in Patent Documents 1 and 2.

  FIG. 10 shows a second example of a mouthpiece manufacturing apparatus for raising the hyoid bone. The mouthpiece manufacturing apparatus for raising the hyoid bone automatically manufactures the mouthpiece 10 for raising the hyoid bone using a 3D printer.

  As shown in FIG. 10, this mouthpiece manufacturing apparatus for raising the hyoid bone has a 3D printer 200 and a memory 300. The memory 300 stores data of the three-dimensional coordinates of the dentition of the user of the mouthpiece 10 for raising the hyoid bone. The data of the three-dimensional coordinates of the dentition can be obtained by the method described above.

  A method of manufacturing the hyoid bone lifting mouthpiece 10 using the hyoid bone raising mouthpiece manufacturing apparatus will be described. Here, as an example, a case of manufacturing a maxillary dentition-mounted hyoid bone lifting mouthpiece 10 will be described.

  Similar to the case of using the first example of the hyoid bone lifting mouthpiece manufacturing apparatus, the synthetic resin sheet used for manufacturing the hyoid bone lifting mouthpiece 10 corresponding to the required increase in the vertical interchin distance. A thickness Δ of 90 is determined. Then, the data of the three-dimensional coordinates of the dentition of the user of the mouthpiece 10 for hyoid bone elevation stored in the memory 300 is sent to the control unit of the 3D printer 200, and the resin is removed based on the data of the three-dimensional coordinates. A resin layer having a thickness Δ is formed by molding. Thus, the mouthpiece 10 for raising the hyoid bone can be manufactured.

  According to the second example of the hyoid bone lifting mouthpiece manufacturing apparatus, the hyoid bone raising mouthpiece 10 can be automatically manufactured using the 3D printer 200.

  FIG. 11 shows a third example of a mouthpiece manufacturing apparatus for raising the hyoid bone. The mouthpiece manufacturing apparatus for raising the hyoid bone automatically manufactures the mouthpiece 10 for raising the hyoid bone using a 3D printer.

  As shown in FIG. 11, the mouthpiece manufacturing apparatus for raising the hyoid bone includes a 3D printer 200, a memory 300, a determination device 400, and an arithmetic device 500. The memory 300 stores three-dimensional coordinate data of the tooth row of the user of the mouthpiece 10 for raising the hyoid bone. The data of the three-dimensional coordinates of the dentition can be obtained by the method described above. The determination device 400 uses the hyoid bone, Sera S, gonion Go and Menton Me detected by the lateral head and neck X-ray imaging at the central occlusion of the user, and the center of the detected hyoid bone body is It is determined whether or not it is included in a region above a perpendicular drawn from Me to an extension of the line segment S-Go. Arithmetic unit 500 is determined by determination device 400 to be such that the detected center of the body of the hyoid bone is not included in the region above the perpendicular drawn from Me to the extension of line segment S-Go. In this case, the increase in the vertical intermaxillary distance of the user causes the center of the body of the hyoid bone to be included in an area above the perpendicular drawn from Me to the extension of the line segment S-Go, or An increase amount Δ of the vertical inter-jaw distance when approaching the region is determined.

  A method of manufacturing the hyoid bone lifting mouthpiece 10 using the hyoid bone raising mouthpiece manufacturing apparatus will be described. Here, as an example, a case of manufacturing a maxillary dentition-mounted hyoid bone lifting mouthpiece 10 will be described.

  In the first method, first, a lateral head and neck radiograph is taken at a central occlusal position of the user to detect a hyoid bone, a serra S, a gonion Go, and a mentone Me. The determination device 400 determines whether or not the center of the body of the hyoid bone thus detected is included in a region above a perpendicular drawn from Me to an extension of the line segment S-Go. If the determination device 400 determines that the detected center of the body of the hyoid bone is not included in the region above the perpendicular drawn from Me to the extension of the line segment S-Go, Due to the increase of the vertical intermaxillary distance of the user, the center of the body of the hyoid bone is included in the area above or perpendicular to the extension of the line segment S-Go from Me, or approaches the area. At this time, the increase amount Δ of the vertical inter-chin distance is obtained. Then, the three-dimensional coordinate data of the user's maxillary dentition stored in the memory 300 is sent to the control unit of the 3D printer 200, and the resin is molded by the 3D printer 200 so that the vertical inter-chin distance increases by Δ. The mouthpiece 10 for bone elevation is manufactured.

A region where the center of the detected body of the hyoid bone is above a perpendicular line drawn from Me to an extension of the line segment S-Go, a perpendicular line dropped from Me to an extension of the line segment S-Go, and a line segment from Me. The determination device 400 determines which of a region between the perpendicular to the extension of the Cd-Go and a region below the perpendicular from the Me to the extension of the line segment Cd-Go is included in the determination device 400. . The center of the detected body of the hyoid bone is included in the region between the perpendicular drawn from Me to the extension of the segment S-Go and the perpendicular from Me to the extension of the segment Cd-Go. If it is determined that the center of the body of the hyoid bone is lower than the vertical line extending from Me to the extension of the line segment S-Go due to the increase in the vertical intermaxillary distance of the user, will be included in, or, when approaching the area, the determined increment delta ₁ between the vertical jaw distance, or center of the body portion of the detected hyoid from Me line segments Cd-Go If it is determined that it is included in the area below the perpendicular drawn down to the extension, the center of the body of the hyoid bone is extended from Me by the extension of the line segment S-Go due to an increase in the vertical intermaxillary distance of the user. Between the perpendicular drawn down to Me and the perpendicular drawn down from Me to the extension of the line segment Cd-Go or Me From the vertical line drawn from the Me to the extended line of the line segment S-Go, or from the Me line to the extended line of the line segment S-Go and an extension of the line segment Cd-Go from the Me line. when approaching the region between the perpendicular dropped to the line, obtain the increment delta ₂ between the vertical jaw distance. Then, send the three-dimensional coordinate data of the dentition of the upper jaw of the user stored in the memory 300 to the 3D printer 200, that the distance between the vertical jaws forming the resin so as to increase delta ₁ or delta ₂ by 3D printer 200 Thus, a mouthpiece 10 for raising the hyoid bone is manufactured.

  The determination device 400 can be configured by a conventionally known technique. For example, from the detected center of the body of the hyoid bone, S, Go, Me, and Cd, the determination device 400 lowers the center of the body of the hyoid bone from Me to an extension of the line segment S-Go. A program for determining whether or not the region is included in a region above the perpendicular line, or a region above the perpendicular line in which the center of the detected body of the hyoid bone is lowered from Me to an extension of the line segment S-Go, and a line from Me. The region between the perpendicular drawn down from the extension of the segment S-Go and the perpendicular drawn down from Me to the extension of the line Cd-Go, and the region below the perpendicular drawn down from Me to the extension of the line Cd-Go Out of which of the above-mentioned areas is included in the computer.

  According to the third example of the hyoid bone lifting mouthpiece manufacturing apparatus, the process from the determination of the amount of increase in the vertical intermaxillary distance to the manufacturing of the hyoid bone raising mouthpiece 10 by the 3D printer 200 is automatically performed. Can be.

  As described above, according to this embodiment, when the user wears the upper or lower jaw so as to cover the dentition, the vertical intermaxillary distance increases by 2 mm or more and 4 mm or less, thereby raising the hyoid bone. The body of the hyoid bone, for example, if the center of the body of the hyoid bone before installation is included in a region below the perpendicular drawn from Me to an extension of the segment S-Go. Can be included in a region above a vertical line drawn from Me to an extension of the line segment S-Go, and it is possible to improve the symptoms of obstructive sleep apnea syndrome of the user as much as possible. In addition, it is possible to easily and surely produce the hyoid bone lifting mouthpiece 10 which does not burden the user even when worn by the user, and to provide the member 101 quickly.
