The mandibular advancing device is positioned by the screw member to set the front-back position of the curved members.

U.S. Patent Application Publication No. 2002/0000230

For mouthpieces used to prevent and treat sleep apnea syndrome and snoring, adjust the anterior-posterior position of the mandibular mouthpiece with respect to the maxillary mouthpiece and move the mandibular mouthpiece posterior to the predetermined position. A function to regulate is required. The position of the lower jaw mouthpiece in the anteroposterior direction at this time is adjusted assuming that the wearer has his mouth closed for the purpose of preventing the wearer wearing the mouthpiece from drying out in the oral cavity. Is normal. Further, from the viewpoint of suppressing the reduction of the airway opening effect due to the misalignment of the upper jaw and the lower jaw of the wearer wearing the mouthpiece, the mouthpiece may have a structure that prevents the wearer from opening freely. It is normal. In addition, in order to suppress the free opening of the wearer and maintain the closed state, it is recommended that the wearer wear the lip seal at the same time when using the mouthpiece. The wearer of the mouthpiece is maintained in the closed state at the time of wearing.

As described above, the wearer of the mouthpiece is restricted from opening while wearing the mouthpiece, and therefore it is more difficult to breathe through the mouth when wearing the mouthpiece than when not wearing it. Therefore, there is a demand for a mouthpiece that facilitates mouth breathing while maintaining a closed mouth state.

In view of the above, it is an object of the present invention to provide a mouthpiece that can facilitate mouth breathing at the time of wearing while adjusting the position of the mandibular mouthpiece in the anteroposterior direction with respect to the maxillary mouthpiece.

Mouthpieces according to one aspect of the present invention for solving the above problems include a pair of maxillary and mandibular mouthpieces, a position adjusting unit that adjusts the position of the maxillary mouthpiece in the anteroposterior direction with respect to the maxillary mouthpiece, and a position adjusting unit. A mouthpiece having a respiratory support portion provided on the maxillary and lower jaw mouthpieces. The respiratory support unit partially separates the upper and lower lips of the wearer and communicates the inside and outside of the wearer's oral cavity to support mouth breathing.

According to the present invention, there is provided a mouthpiece capable of facilitating mouth breathing at the time of wearing while adjusting the position of the lower jaw mouthpiece in the anteroposterior direction with respect to the upper jaw mouthpiece.

[First Embodiment]
FIG. 1 is a schematic perspective view showing the configuration of the mouthpiece 100 according to the first embodiment of the present invention.

The mouthpiece 100 is a pair of left and right maxillary and mandibular mouthpieces that connect the maxillary and mandibular mouthpieces that act as a position adjusting unit that adjusts the position of the maxillary mouthpiece in the anterior-posterior direction with respect to the pair of facing maxillary and mandibular mouthpieces. It has a connecting member 170 of. The maxillary mouthpiece 110 can be attached to the upper jaw of the user, and the lower jaw mouthpiece 120 can be attached to the lower jaw of the user.

Further, the mouthpiece 100 has a breathing support portion (cylindrical member 150 and cavity portion 160, which will be described later) that partially communicates air inside and outside the wearer's lips to support the wearer's mouth breathing.

The maxillary mouthpiece 110 is configured so that it can be attached to the upper jaw of the user by forming a dentition type taking portion 112 that can be attached to the dentition of the upper jaw of the user. In addition, the mandibular mouthpiece 120 is configured so that it can be attached to the lower jaw of the user by forming a dentition type taking portion 122 that can be attached to the dentition of the lower jaw of the user.

In the mouthpiece 100, one end (upper mounting portion 172a) of the connecting member 170 is attached to one side point (upper holding portion 130) of the upper jaw mouthpiece 110, and the other end (lower mounting portion 174a) of the connecting member 170 is attached. ) Is attached to another point (lower holding portion 140) on the side surface of the lower jaw mouthpiece 120, so that the lower jaw mouthpiece 120 is connected to the upper jaw mouthpiece 110.

Further, the mouthpiece 100 has an upper holding portion 130 for attaching and rotatably holding the upper mounting portion 172a of the outer 172 of the connecting member 170 on the outer wall surface of the upper jaw mouthpiece 110. Further, the mouthpiece 100 has a lower holding portion 140 for attaching and rotatably holding the lower mounting portion 174a of the inner 174 of the connecting member 170 on the outer wall surface of the lower jaw mouthpiece 120. The lower holding portion 140 is arranged at a position in front of the upper holding portion 130 when mounted.

The connecting member 170 has an outer 172 and an inner 174 that is inserted into the outer 172 and is slidably held with respect to the outer 172.

The outer 172 is a tubular member that is rotatably attached to the maxillary mouthpiece 110 by an eyelet-shaped upper attachment portion 172a. The upper mounting portion 172a included in the outer 172 is arranged laterally with respect to the main body of the outer 172 which is a tubular portion. The inner 174 is a rod-shaped insert that is rotatably attached to the lower jaw mouthpiece 120 by an eyelet-shaped lower attachment portion 174a. The lower mounting portion 174a included in the inner 174 is arranged substantially in the same straight line as the direction in which the inner 174 is inserted into the outer 172. The inner 174 is inserted into the cylinder of the outer 172 and connected to the outer 172.

When the connecting member 170 is attached to the upper jaw mouthpiece 110 and the lower jaw mouthpiece 120, the outer 172 is arranged behind the inner 174. As a result, the connecting member 170 has one point on the side surface (upper holding portion 130) of the upper jaw mouthpiece 110 to which the outer 172 is attached and another point (lower holding) on the side surface of the lower jaw mouthpiece 120 to which the inner 174 is attached. The distance to the unit 140) (minimum value of the distance) is maintained within a predetermined range. As a result, the connecting member 170 adjusts the position of the mandibular mouthpiece 120 in the anteroposterior direction with respect to the maxillary mouthpiece 110, and restricts the movement of the mandibular mouthpiece backward. In the present embodiment, the inner 174 is slidably connected to the outer 172 to expand and contract, and the minimum length of the expandable connecting member 170 is such that the lower jaw mouthpiece 120 is rearward. Specify the limit that can be displaced.

Further, the connecting member 170 enables the wearer's lower jaw to move freely forward or downward within the range in which the inner 174 can slide, and can reduce the discomfort of the user.

Further, the connecting member 170 is configured so that the maximum width that the inner 174 can be inserted into the outer 172 can be changed by a screw member (not shown) or the like. Thereby, the minimum length of the connecting member 170 can be changed to change the position of the mandibular mouthpiece 120 in the anteroposterior direction with respect to the maxillary mouthpiece 110 at the time of wearing (the limit at which the mandibular mouthpiece 120 can be displaced rearward). ..

In the present embodiment, the mouthpiece 100 has a tubular member 150 that protrudes forward from the outer wall surface of the front end of the maxillary mouthpiece 110. One end 152 of the tubular member 150 is connected to the maxillary mouthpiece 110, whereby one end 152 is arranged inside the wearer's lips when the mouthpiece 100 is attached. Further, the tubular member 150 is arranged at a position where the other end 154 extends forward from the one end 152, whereby the other end 154 is attached to the wearer when the mouthpiece 100 is attached. Placed on the outside of the lips.

The maxillary mouthpiece 110 has a cavity 160 inside. The cavity 160 is connected to one end 152 of the tubular member 150, whereby the inside of the tubular member 150 and the inside of the cavity 160 are air-communicated.

Further, in the cavity 160, a pair of left and

right air passages

162a and 162b passing through the inside of the maxillary mouthpiece 110 and a pair of left and

right air passages

162a and 162b are wall surfaces (mounted) on the left and right rear ends of the maxillary mouthpiece 110, respectively. It has a pair of left and right

first openings

164a and 164b that are opened on the posterior surface side of the back teeth of the person. As a result, the hollow portion 160 is air-communicated from the connection portion with one end portion 152 of the tubular member 150 to the

first openings

164a and 164b at the rear end portion of the maxillary mouthpiece 110. The pair of left and

right air passages

162a and 162b are one air passage connected to each other at a connection portion to one end portion 152 of the tubular member 150.

When the wearer wears the mouthpiece 100, the tubular member 150 is held by the wearer's lips, and the other end 154 of the tubular member 150 is arranged outside the wearer's lips. Therefore, the mouthpiece 100 allows the exhaled breath of the wearer that has flowed into the

air passages

162a and 162b from the

first openings

164a and 164b to the inside of the tubular member 150 through one end 152 of the tubular member 150. It is discharged to the outside from the other end 154 of the tubular member 150 arranged on the outside of the wearer's lips. Further, the mouthpiece 100 allows the external air flowing in from the other end 154 of the tubular member 150 arranged on the outside of the wearer's lips to pass through the air passage 162a through one end 152 of the tubular member 150. And 162b, and introduced from the

first openings

164a and 164b into the wearer's oral cavity (inside the dentition). In this way, the mouthpiece 100 assists the wearer's mouth breathing.

At this time, since the wall surface of the rear end of the maxillary mouthpiece 110 is open in both of the

first openings

164a and 164b, the

first openings

164a and 164b are closed even if the wearer moves the tongue. Hateful. Therefore, in the mouthpiece 100 of the present embodiment, the obstruction of mouth breathing due to the closure of the

first openings

164a and 164b by the wearer's tongue is unlikely to occur.

The length of the tubular member 150 is not particularly limited as long as the other end 154 is arranged on the outside of the wearer's lips, but can be, for example, 1 mm or more and 20 mm or less.

The diameter of the tubular member 150 is not particularly limited as long as it is large enough to allow the wearer to easily breathe through the mouth, but can be, for example, 2 mm or more and 10 mm or less.

The maxillary mouthpiece 110 and the mandibular mouthpiece 120 are made of a material that is not easily damaged by the normal human occlusal force.

For example, the maxillary mouthpiece 110 and the mandibular mouthpiece 120 are a single hard material (for example, acrylic resin) having a flexural modulus of 2000 MPa or more and 3000 MPa or less measured according to JIS T6501, or a soft material of 10 MPa or more and 300 MPa or less. It may be formed from a material in which a hard material of 1000 MPa or more and 3000 MPa or less is combined.

Further, the maxillary mouthpiece 110 and the mandibular mouthpiece 120 may be formed of a relatively soft material having a tensile strength of 150 N or more and less than 2000 N, preferably 150 N or more and 500 N or less, in order to enhance the followability of the user's teeth.

The tensile strength is obtained when a hole of φ1.5 mm is made in the dentition No. 6 of the maxillary mouthpiece of the mouthpiece (thickness 3 mm) manufactured using the Nissin standard model, and a tensile test is performed in the molar direction (posterior). In addition, it means the strength at which the maxillary mouthpiece is torn.

Examples of the material having a tensile strength of 150 N or more and less than 2000 N include an olefin resin, a polyester resin, a urethane resin, a polyamide resin, and an acrylic rubber resin. Of these, olefin resins are preferred.

The olefin resin is a polymer obtained by homopolymerizing an olefin or a copolymer obtained by polymerizing an olefin and another monomer. As the olefin, an olefin having 2 to 6 carbon atoms including ethylene, propylene, butene, methylpentene, and hexene is preferable. Examples of the other monomers include vinyl acetate and the like.

As the olefin resin, polyethylene (PE), polyethylene resin, polypropylene (PP), polypropylene resin, ethylene / vinyl acetate copolymer (EVA) and the like are preferable, and polyethylene (PE), polyethylene resin, polypropylene and the like are preferable. (PP), polypropylene-based resin and the like are more preferable.

Polyester-based resin is a polycondensate of polyunsaturated carboxylic acid (dicarboxylic acid, etc.) and polyalcohol (diol, etc.). Examples of the polyester-based resin include polyethylene terephthalate (PET) and the like.

Urethane-based resin is a polycondensate of a compound having an isocyanate group and a compound having a hydroxyl group. Examples of the urethane-based resin include thermoplastic polyurethane (TPU) and the like.

Polyamide-based resin is a (co) polymer formed by bonding a large number of monomers by amide bonds. Examples of the above-mentioned polyamide-based resin include nylon, para-based amide, meta-based amide, and the like.

Acrylic rubber resin is a (co) polymer containing acrylic rubber as a main component. Examples of the acrylic rubber include block copolymers of methyl methacrylate and butyl acrylate.

As a material having a tensile strength of 150 N or more and less than 2000 N, a commercially available material such as F327 (polypropylene resin) manufactured by Prime Polymer Co., Ltd. may be used.

The tubular member 150 is measured according to titanium or an alloy containing titanium, iron (steel containing stainless steel, etc.), a metal material such as an alloy such as gold, silver, platinum, cobalt, and chromium, and JIS T6501. It can be formed from a hard resin material (for example, polycarbonate resin) having a flexural modulus of 1000 MPa or more and 3000 MPa or less. The metal material may have improved corrosion resistance by a chemical conversion film or the like.

In the mouthpiece 100 of the present embodiment, only a part of the wearer's lips on which the tubular member 150 is arranged is partially separated from the upper and lower lips. Then, the mouthpiece 100 introduces the external air that has flowed into the tubular member 150 into the oral cavity from the back of the wearer's back teeth, and introduces the wearer's exhaled breath from the back of the wearer's back teeth into the cavity 160. It is discharged from the tubular member 150 to the outside. At this time, other parts of the wearer's lips on which the tubular member 150 is not arranged remain closed. Therefore, the mouthpiece 100 can support the wearer's mouth breathing while suppressing the dryness of the oral cavity by opening the wearer's mouth.

Since the mouthpiece 100 of the present embodiment can support the wearer's mouth breathing without opening the wearer (without moving the mandibular mouthpiece 120 in the opening direction), the mandibular mouse can be used during mouth breathing. The movement of the piece 120 in the opening direction makes it difficult for the mandibular mouthpiece 120 to be displaced in the anteroposterior direction. Therefore, the mouthpiece 100 of the present embodiment is unlikely to reduce the airway opening effect due to the displacement of the lower jaw mouthpiece 120 during mouth breathing.

Further, in the mouthpiece 100 of the present embodiment, the maxillary mouthpiece 110 has a cavity 160 inside, and air is communicated inside and outside the oral cavity through the cavity 160. Therefore, the respiratory support units (

air passages

162a and 162b) do not interfere with the use of the mouthpiece 100, and the

air passages

162a and 162b are not crushed by occlusion.

In the present embodiment, the example in which the maxillary mouthpiece 110 has a cavity 160 is shown, but the mandibular mouthpiece 120 may have a cavity, and both the maxillary mouthpiece 110 and the mandibular mouthpiece 120 may have a cavity. May have a cavity.

Further, the tubular member 150 may have a hardness that does not crush even when tightened by the upper and lower lips, and may be made of metal, a hose made of resin, or the like.

[Second Embodiment]
FIG. 2 is a schematic perspective view showing the configuration of the mouthpiece 200 according to the second embodiment of the present invention.

The mouthpiece 200 differs from the mouthpiece 100 according to the first embodiment only in the configuration of the cavity 260. Therefore, the description of the common configuration is omitted, and the differences will be described below.

In the mouthpiece 200, in addition to the pair of left and right

first openings

264a and 264b in which the cavity 260 has

air passages

262a and 262b opened in the wall surfaces of the left and right rear ends of the maxillary mouthpiece 110, respectively, the maxillary mouthpiece 110 It has a pair of left and right

second openings

266a and 266b in which

air passages

262a and 262b are opened on the inner wall surfaces of the left and right dentitions, respectively.

Since both the

second openings

266a and 266b are open to the wall surface inside the dentition of the maxillary mouthpiece 110, the openings can be wider than the

first openings

264a and 264b. Thereby, the

second openings

266a and 266b can make it easier for the wearer to breathe through the cavity 260.

Further, due to the formation of the

second openings

266a and 266b, the length of the closed portion of the

air passages

262a and 262b is shorter than that of the first embodiment. Therefore, the

air passages

262a and 262b are less likely to be blocked by the wearer's saliva or leftover food in the oral cavity. Further, in the present embodiment, since the

second openings

266a and 266b have a mesh shape, saliva of the wearer and leftover food in the oral cavity are less likely to enter the inside of the

air passages

262a and 262b. Therefore, the blockage of the

air passages

262a and 262b is less likely to occur.

The

second openings

266a and 266b may be formed over the entire width inside the dentition, but may be formed only at a part inside the dentition, for example, a part from the rear end.

Further, in order to more effectively suppress saliva and leftover food in the oral cavity of the wearer inside the

air passages

262a and 262b, the

first openings

264a and 264b may also be mesh-shaped openings. ..

Further, in the present embodiment, an example is shown in which the cavity portion 260 has both the

first openings

264a and 264b and the

second openings

266a and 266b, but the cavity portion 260 has only the

second openings

266a and 266b. You may be doing it.

The mouthpiece 200 of the present embodiment can widen the opening in the oral cavity to facilitate the wearer's mouth breathing.

Further, the mouthpiece 200 of the present embodiment is less likely to be blocked in the cavity and is easy to maintain.

[Third Embodiment]
FIG. 3 is a schematic perspective view showing the configuration of the mouthpiece 300 according to the third embodiment of the present invention.

The mouthpiece 300 differs from the mouthpiece 100 according to the first embodiment only in the configuration of the tubular member and the cavity. Therefore, the description of the common configuration is omitted, and the differences will be described below.

The mouthpiece 300 has two

tubular members

350a and 350b protruding forward from the outer wall surface of the front end of the maxillary mouthpiece 110. In each of the two

tubular members

350a and 350b, one

end

352a and 352b are connected to the maxillary mouthpiece 110, whereby when the mouthpiece 100 is attached, one

end

352a and 352b is attached to the wearer. Placed inside the lips. Further, both the

tubular members

350a and 350b are arranged at positions where the other ends 354a and 354b extend forward from the corresponding ends 352a and 352b, respectively, whereby the mouthpiece 100 When worn, the other ends 354a and 354b are both placed on the outside of the wearer's lips.

Further, each of the one

end portions

352a and 352b of the two

tubular members

350a and 350b is connected to the hollow portion 360 that the maxillary mouthpiece 110 has inside thereof, whereby the tubular member 350a is connected. The inside of the cavity 360 is air-communicated with the inside of the cavity 360, and the inside of the tubular member 350b and the inside of the cavity 360 are air-communicated.

Further, also in the present embodiment, in the cavity portion 360, the pair of left and

right air passages

362a and 362b passing through the inside of the maxillary mouthpiece 110 and the pair of left and

right air passages

362a and 362b are left and right rear of the maxillary mouthpiece 110, respectively. It has a pair of left and right

first openings

364a and 364b that are open at the ends. Further, the pair of left and

right air passages

362a and 362b are one air passage connected to each other in a region including a connection portion to one

end portion

352a and 352b of the

tubular members

350a and 350b. As a result, the hollow portion 360 allows air to communicate from the connection portion with one end portion 352a of the tubular member 350a to the

first openings

364a and 364b at the rear end portion of the maxillary mouthpiece 110, and the tubular member. Air is communicated from the connection portion with one end portion 352b of 350b to the

first openings

364a and 364b at the rear end portion of the maxillary mouthpiece 110.

The pair of left and

right air passages

362a and 362b are not communicated with each other, and even if an air passage 362a communicating with the tubular member 350a and an air passage 362b communicating with the tubular member 350b are provided independently. Good. However, if the air passage 362a and the air passage 362b communicate with each other as in the present embodiment, even when one air passage is blocked, mouth breathing using the other air passage becomes easy. Therefore, it is preferable.

Further, the number of tubular members may be two or three or more.

The distance between the plurality of tubular members 350a and the tubular member 350b is not particularly limited, but from the viewpoint of preventing the wearer from drying in the oral cavity due to the opening of the lips between the tubular member 350a and the tubular member 350b. From the above, it is preferable to keep a predetermined distance. For example, the distance between the tubular member 350a and the tubular member 350b can be 1 mm or more and 10 mm or less.

Since the mouthpiece 300 of the present embodiment has a plurality of tubular members, it is possible to make the wearer's mouth breathing easier.

In the present embodiment as well, as in the second embodiment, the cavity portion 360 has an air passage 362a and an air passage 362a on the inner wall surface of the left and right dentition of the maxillary mouthpiece 110 in addition to the

first openings

364a and 364b. 362b may each have a pair of left and right second openings that are open.

Further, in the present embodiment, the plurality of tubular members are arranged independently, but any one of the plurality of tubular members may be connected to each other by the tubular members. .. That is, in the present embodiment, the number of connecting portions in which one end of the tubular member is connected to the air passage and the number of tubular members are the same, but from one of the above connecting portions. The number of the connecting portions may be smaller than the number of the tubular members because the plurality of tubular members are branched or the like.

[Fourth Embodiment]
FIG. 4 is a schematic side view showing the configuration of the mouthpiece 400 according to the fourth embodiment of the present invention. Regarding the present embodiment as well, the description of the configuration common to the other embodiments will be omitted, and the differences will be described below.

The mouthpiece 400 has a pair of left and right spacers 480 sandwiched between the maxillary mouthpiece 110 and the mandibular mouthpiece 120.

Spacer 480 is a removable member having a predetermined thickness. By sandwiching the spacer 480 between the upper jaw mouthpiece 110 and the lower jaw mouthpiece 120, the dentition surface 414 of the upper jaw mouthpiece 110 and the dentition surface 424 of the lower jaw mouthpiece 120 are separated from each other, and the upper jaw mouthpiece A gap 484 is formed between the dentition surface 414 of 110 and the dentition surface 424 of the lower jaw mouthpiece 120.

Further, in this embodiment, the mouthpiece 400 does not have a cavity inside the maxillary mouthpiece 110. Then, one end 452 of the tubular member 450 is fixed to the wall surface on the dentition surface 414 side of the front end of the maxillary mouthpiece 110. Further, in the tubular member 450, one end 452 is a gap portion 484 at the front end of the mouthpiece 400 between the dentition surface 414 of the maxillary mouthpiece 110 and the dentition surface 424 of the mandibular mouthpiece 120. It is open to the mouth. On the one hand, the tubular member 450 is arranged so that the other end 454 is on the outside of the wearer's lips when the mouthpiece 400 is worn.

The mouthpiece 400 allows the exhaled breath of the wearer discharged from the inside of the dentition in the oral cavity to pass through the gap 484 between the dentition surfaces to one end 452 of the tubular member 450. The air that has reached one end 452 of the tubular member 450 is introduced into the inside of the tubular member 450 from the gap 484 between the dentition surfaces, and the tubular member 450 arranged on the outside of the wearer's lips. It is discharged to the outside from the other end 454 of the. Further, the mouthpiece 400 allows the external air flowing in from the other end 454 of the tubular member 450 arranged on the outside of the wearer's lips to flow from the one end 452 of the tubular member 450 to the dentition surface. It is introduced into the gap 484 between them. The air introduced into the gap portion 484 travels along the gap portion 484 between the dentition surfaces and is introduced into the oral cavity inside the dentition.

At this time, even if the space between the oral cavity inside the dentition and the gap 484 between the dentition surfaces is partially blocked by the wearer's tongue, the exhalation and air (intake) are still in other parts. Can move between the oral cavity inside the dentition and the gap 484 between the dentition surfaces. Therefore, in the mouthpiece 400, mouth breathing is not hindered by the movement of the wearer's tongue.

In addition, the spacer 480 opens the airway of the wearer more by widening the distance between the upper jaw and the lower jaw of the wearer. Therefore, the spacer 480 can sufficiently open the airway of the wearer while reducing the amount of forward position adjustment of the mandibular mouthpiece 120. As a result, the spacer 480 can also suppress a decrease in the wearing feeling of the wearer due to the large movement of the lower jaw forward.

The spacer 480 and the position where the spacer 480 of the maxillary mouthpiece 110 or the mandibular mouthpiece 120 is arranged have a shape such as a shape that meshes with each other or a shape in which one is fitted into the other. A locking structure for stopping may be formed.

The thickness of the spacer 480 is not particularly limited. For example, if the thickness of the spacer 480 is set to be about the same as the distance between the upper and lower teeth of the wearer, it is possible to facilitate mouth breathing while reducing the discomfort caused by wearing the mouthpiece 400. Alternatively, if the thickness of the spacer 480 is increased to make it easier to open the wearer's throat, the effect of suppressing sleep apnea syndrome and snoring can be enhanced at the same time. The thickness of the spacer 480 may be adjustable according to the above purpose and the like. Further, the thicknesses of the left and right spacers 480 may be different from each other depending on the shape of the wearer's oral cavity and dentition.

Further, the spacers 480 do not have to be paired on the left and right, and only one spacer 480 may be arranged at the front end portion of the mouthpiece or the like, or three or more spacers may be arranged.

Further, in order to reduce the obstruction of exhalation or inspiration by the spacer, the spacer may have a shape that allows air to pass through, such as a mesh, and the spacer may be formed by the maxillary mouthpiece 110 and the mandibular mouthpiece 120. It may be arranged so as to be in contact with only a part of the width in the inward and outward directions between the dentition surfaces.

The mouthpiece 400 of the present embodiment does not have a hollow portion, and can facilitate mouth breathing by the wearer with a simpler configuration of a spacer 480 and a tubular member 450 (breathing support portion in the present embodiment).

In this embodiment as well, as in the first to third embodiments, a cavity is provided inside the maxillary or mandibular mouthpiece, and the cavity is connected to one end of the tubular member. A respiratory support portion that is opened at the posterior end of the maxillary or mandibular mouthpiece or inside the dentition may be used in combination.

Further, in the present embodiment, the upper and lower lips of the wearer may be partially separated by using an opening member having another shape instead of the tubular member 450. The width of the opening member in the vertical direction may be large enough to separate the upper and lower lips of the wearer to allow air to communicate with each other, and not so large as to make the wearer feel uncomfortable. Further, the width of the opening member in the left-right direction may be such that the upper and lower lips of the wearer are totally separated from each other and the oral cavity of the wearer is not dried.
