Patent Document 1: International Publication No. 2009/001565 Patent Document 2: Japanese Patent Publication No. 2006-513738 Patent Document 3: International Publication No. 2016/191826 Patent Document 4: International Publication No. 2020/089796

[Problem to be solved by the invention]

Patent Document 1 discloses a brace that includes a front wall covering the front side of the teeth, a rear wall covering the rear side of the teeth, and a brace that connects the front wall and the rear wall and connects the upper and lower jaw teeth. The occlusal part of the occlusion between the rows; the front wall part, the rear wall part and the occlusal part are formed by using flexible and impact-absorbing porous materials. The occlusal part deforms according to the bite force between the upper and lower jaw rows, and is connected with the front wall Compared with the front wall and the back wall, the density in the cross section in the bite direction is increased, which can form a stable bite portion that is closely connected to the upper and lower jaw teeth.

According to the brace of Patent Document 1, the stress of the porous material allows the occlusal portion to deform in accordance with the shape of the tooth rows and come into close contact without gaps, thereby forming an occlusal stabilizing portion in the occlusal portion, which is fixed relative to the front wall portion and the rear wall portion. In other words, the density in the section in the bite direction is relatively increased.

Patent Document 2 discloses a dental brace that includes an upper jaw shell and a lower jaw shell that accommodate upper and lower rows of teeth respectively. The upper and lower jaw shells are connected by a method that can be separated while maintaining contact. The upper and lower jaw shells are The mandibular shell has a greater thickness than known dental appliances, and the mechanism connecting the upper mandibular shell and the lower mandibular shell also has a greater thickness than known dental appliances.

According to the braces in Patent Document 2, the large molars can be treated deep in the user's mouth. Due to the thickness between the upper and lower jaw shells, when the user installs the dental appliance in the oral cavity, the muscles in the user's oral cavity can be stimulated, and the muscles in the user's oral cavity can be stimulated. The hinge or other mechanism that connects the upper and lower jaw shells of the dental appliance can make the entire dental appliance elastic due to the increased thickness of the rear portion. The mechanism that connects the upper and lower jaw shells can limit the movement of the opposite sides of the user's jaw.

Patent Document 3 discloses the following braces, which have: a U-shaped base corresponding to at least part of the upper and lower jaws from the central incisor to the second molar; and an upper outer wall extending from the base on the upper jaw side. When worn, It is located between the central incisor of the upper jaw and the upper lip, and is formed in such a way that at least the labial side of the central incisor of the upper jaw can contact; and the lower inner wall is extended from the base to the lower jaw side, and is positioned between the central incisor of the lower jaw and the upper lip when worn. Between the tongues, at least the lingual side surfaces of the central incisors of the mandible can come into contact; and a first cutting guide portion is formed on at least a part of the base corresponding to the molar portion. Furthermore, Patent Document 4 discloses a dental brace in which a cutting guide portion is formed at a position corresponding to a first molar tooth and a second molar tooth.

However, with the recent advancement of medical technology, human lifespan has been extended, and it is difficult to maintain one's own teeth throughout life without taking any countermeasures. Therefore, it has become very important to protect teeth by using braces. Braces are usually commercially available and can be made (customized) by taking a personal dental mold or based on a standard dentition. The former has the problem of easily becoming expensive, while the latter has the problem of difficulty in finding braces that match the dentition.

Therefore, the object of the present invention is to provide a dental brace that can be used for life even if no tooth mold is taken to make it. [Means to solve problems]

The present invention solves the above problems through the following dental braces, which are characterized by: The U-shaped base corresponds to at least part of the upper and lower jaws from the central incisors to the second largest molar; The upper outer wall is extended from the base to the side of the upper jaw, and when worn, is positioned between the central incisor of the upper jaw and the upper lip, and is configured in such a way that at least the labial side of the central incisor of the upper jaw can come into contact; The lower inner wall is extended from the base to the side of the lower jaw. When worn, it is positioned between the central incisor of the lower jaw and the tongue, and is configured in such a way that at least the lingual side of the central incisor of the lower jaw can come into contact, and is formed to The position corresponding to the end of the above-mentioned base or the first molar; and The tongue resting portion extends from the lower inner wall to the inside of the U-shape of the base and toward the lower jaw, and has a groove in the center to form a U-shape in the same direction as the base; and A first cutting guide portion is formed at at least a portion of the base portion and the lower inner wall corresponding to the position between the second minor molar and the first major molar; A second cutting guide portion is formed at at least a portion of the base portion and the lower inner wall corresponding to the position between the first molar tooth and the second molar tooth; A first tongue-setting cutting guide portion and/or a second tongue-setting portion cutting guide portion respectively corresponding to the first cutting guide portion and/or the second cutting guide portion are formed on the tongue setting portion; and The tongue placement portion further includes a U-shaped cutting guide portion along the base portion. [Effects of the invention]

The braces according to the present invention are provided with: an upper outer wall extending from the base to the upper jaw side, and when worn, is located between the central incisor of the upper jaw and the upper lip, and is configured in such a way that at least the labial side of the central incisor of the upper jaw can abut. ; and the lower inner wall is extended from the base to the side of the mandible. When worn, it is located between the central incisor of the mandible and the tongue, and is constructed in such a way that at least the lingual side of the central incisor of the mandible can come into contact; therefore, it should be worn with When the head is tilted up with braces, and the force in the downward direction caused by gravity acts on the jaw, at least the central incisor of the lower jaw is hooked on at least the central incisor of the upper jaw through the braces, which prevents the jaw from moving in the downward direction when the head is tilted up. . In addition, since it has a U-shaped tongue resting portion that extends from the lower inner wall to the inside of the base and toward the lower jaw and has a groove in the center, the tongue tip can be easily connected to the hard tongue by placing the tongue on the tongue resting portion. The palate is offset to prevent and improve low tongue position or snoring. Furthermore, due to the U-shaped base and lower inner wall corresponding to at least part of the central incisors of the upper and lower jaws to the second molar, there is a gap between the second molar and the first molar and between the first molar and the second molar. At least a part of the corresponding position between the two molars is provided with a first cutting guide part and a second cutting guide part, and the lingual part is provided with a first cutting guide part and a second cutting guide part respectively corresponding to the first cutting guide part and the second cutting guide part. The first tongue setting portion cuts the guide portion and the second tongue setting portion cuts the guide portion, so it is easy to cut the brace along the first and second cutting guide portions and the first and second tongue setting portions. Cut off at the corresponding positions between the second molar and the first molar and between the first and the second molar. In this way, from the time when the deciduous teeth from the central incisor to the second molar have grown together, until the state before the second molar erupts, and when the permanent teeth from the central incisor to the second molar have grown together, the same mold can be used throughout the life. Braces.

Thereby, the user of the dental brace of the present invention obtains the following benefits. First of all, since the same molded braces manufactured at a relatively low cost can be used for life, there is no need to customize braces that match the user's dentition, which is more economical. Secondly, by preventing the jaw from moving in the downward direction when the head is raised, the position of the condyle relative to the skull, especially the mandibular glenoid fossa, can be prevented from shifting. This can prevent the onset of temporomandibular joint disease, or the onset of hearing impairment and other symptoms caused by the condyle moving toward the ear hole, compressing the ear hole or mandibular branch, and the surrounding nerves. In addition, by wearing braces when sleeping, nasal breathing is given priority, which can prevent dryness in the mouth, prevent the proliferation of bacteria or viruses, and also prevent snoring. Especially in the early childhood stage when all the deciduous teeth from the central incisor to the second molar have grown together, the state of giving priority to nasal breathing during sleep can promote the growth of the maxillary sinus. However, underdevelopment of the maxillary sinus is considered to be one of the causes of overbite or reversed occlusion (mandibular protrusion). Therefore, by continuing to use the braces of the present invention since childhood, the overbite or reversed occlusion can be suppressed. On the contrary, the onset of occlusion. In addition, tooth wear is considered to be one of the causes of aging of the corners of the mouth, such as narrowing of the mouth and wrinkles around the mouth including nasolabial folds. Therefore, by placing braces between the teeth of the upper and lower jaws, the wear of the teeth caused by the friction between the teeth can be prevented, and the aging of the corners of the mouth can also be inhibited.

Furthermore, if the thickness of the lingual resting part gradually increases from the end of the base or the position corresponding to the first molar toward the central incisor side, a brace can be formed in which the tip of the tongue can more easily come into contact with the hard palate. .

Furthermore, if the groove of the tongue setting portion is configured to expand toward the end of the base portion, or the first tongue setting portion cutting guide portion and/or the second tongue setting portion cutting guide portion is configured to be inclined toward the central incisor, , and it is easy to cut along the first tongue-position cutting guide part and/or the second tongue-position part cutting guide part, so a brace that is difficult to interfere with the genioglossus muscle can be formed.

In addition, if the tongue resting portion is further provided with a U-shaped cutting guide along the base, and the U-shaped cutting guide can be easily cut along the U-shaped cutting guide, it can be formed that is less likely to interfere with the mandibular protuberance, etc. Braces.

Furthermore, if the upper outer wall, the upper inner wall, and the lower outer wall are formed to a position corresponding to the end of the base or the first molar, each of the user's teeth will be along the upper outer wall, the upper inner wall, or the lower The outer wall can prevent malocclusion, prevent the braces from shifting in the oral cavity, and prevent the jaw from moving in the downward direction when the user sleeps sideways.

Moreover, if the upper outer wall is further provided with a U-shaped upper outer wall cutting guide along the base, the upper outer wall can be easily cut along the upper outer wall upper cutting guide, so that an even shape can be formed. It is a brace that is easy to wear for children or women who have relatively small mouths.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 11 . However, the present invention is not limited to this embodiment.

1 to 4 show a dental brace 10 according to a reference example of the present invention. The structure of the present invention other than the tongue placement portion 40 (described later) is the same as that of the brace 10, so the brace 10 will be described first. The brace 10 has a U-shaped base 12 that corresponds to the dentition, specifically, the curved shape of the dentition from the central incisors to at least part of the second molar of the upper and lower jaws of the human body. The brace 10 has a left-right symmetrical shape when viewed from above.

The base 12 is provided with: an upper outer wall 22, which is extended on the upper palate side and is positioned between the central incisor of the upper palate and the upper lip when worn, and at least the labial side of the central incisor of the upper palate can abut; and an upper inner wall 24, It is configured to be positioned from the central incisor of the upper jaw to between the second molar and the hard palate when worn, and is formed from the central incisor of the base 12 to a position corresponding to the first molar. The upper outer wall 22 and the upper inner wall 24 may be formed in any range up to a position corresponding to the end of the base 12 (see also FIG. 3 ).

As shown in FIG. 2 , the base 12 is provided with a lower inner wall 34 , which is extended on the side of the mandible, is positioned between the central incisor of the mandible and the tongue when worn, and is configured in such a way that at least the lingual side of the central incisor of the mandible can come into contact. ; and the lower outer wall 32 is formed in such a way that when worn, it is located from the central incisor of the lower jaw to between the second molar and the lower lip, and is formed from the central incisor of the base 12 to a position corresponding to the end. The lower inner wall 34 is formed to a position corresponding to the end of the base 12 or the first molar, and the lower outer wall 32 can be formed in any range to a position corresponding to the end of the base 12 (see also FIG. 4 ).

The base 12, the upper outer wall 22, the upper inner wall 24, the lower outer wall 32 and the lower inner wall 34 are made of well-known resin materials. The size, thickness and shape of the base 12, the upper outer wall 22, the upper inner wall 24, the lower outer wall 32 and the lower inner wall 34 can be set arbitrarily, for example, as long as they are based on the standard model of the gender-specific dentition or the standard size in the oral cavity. Just set it.

As mentioned above, the brace 10 is provided with: an upper outer wall 22 extending from the base 12 on the upper palate side. When worn, it is located between the central incisor of the upper jaw and the upper lip, and at least the labial side of the central incisor of the upper jaw can abut. and the lower inner wall 34 is extended from the base 12 to the mandibular side, and is positioned between the central incisor of the mandible and the tongue when worn, and is configured in such a way that at least the lingual side of the central incisor of the mandible can come into contact; therefore, When the user raises his head while wearing the braces 10 and the force in the downward direction caused by gravity acts on the user's jaw, at least the central incisors of the lower jaw are hooked on the at least central incisors of the upper jaw through the braces 10. Prevent the jaw from moving in the downward direction when the head is raised.

Furthermore, if the upper outer wall 22 , the upper inner wall 24 , the lower outer wall 32 and the lower inner wall 34 are formed to a position corresponding to the end of the base 12 or the first molar, each of the user's teeth will be along the The upper outer wall 22, the upper inner wall 24, the lower outer wall 32 or the lower inner wall 34 can prevent malocclusion and prevent the position of the braces in the oral cavity from shifting.

Furthermore, by providing the upper outer wall 22 or the upper inner wall 24 formed to a position corresponding to the end of the base 12 or the first large molar, and the lower wall 22 formed to a position corresponding to the end of the base 12 or the first large molar. The outer wall 32 or the lower inner wall 34, even when the user sleeps sideways, when the force in the downward direction caused by gravity acts on the user's jaw, any tooth of the lower jaw is hooked on the upper jaw through the brace 10 On any of the teeth, it can prevent the jaw from moving in the downward direction.

As shown in FIG. 1 , first cutting guide portions 26 a and 26 b and second cutting guide portions 28 a and 28 b are provided on the upper jaw surface of the base 12 . As long as the first cutting guide portions 26a, 26b are disposed at at least a portion of the base portion 12 at a position corresponding to the second minor molar and the first major molar, and the second cutting guide portions 28a, 28b are disposed at a position corresponding to the first major molar. At least part of the corresponding position between the molar teeth and the second molar tooth is enough.

As shown in FIG. 2 , the base 12 is also provided with first cutting guide portions 36 a and 36 b and second cutting guide portions 38 a and 38 b on the lower jaw surface. The first cutting guide portions 36a, 36b and the second cutting guide portions 38a, 38b provided on the lower jaw surface have the same structure as the first cutting guide portions 26a, 26b and the second cutting guide portion provided on the upper jaw surface. 28a and 28b have the same composition. In addition, the first cutting guide part and the second cutting guide part may be provided on either the upper or lower jaw surface of the base 12 .

In the case of the dental brace 10, the first cutting guide portions 26a, 26b, 36a, 36b and the second cutting guide portions 28a, 28b, 38a, 38b are concave grooves. In addition to grooves, the first cutting guide parts 26a, 26b, 36a, 36b and the second cutting guide parts 28a, 28b, 38a, 38b may also be protrusions, protrusions, holes or holes (including those provided continuously) , or printed or dotted lines. In addition, the first cutting guide portions 26a, 26b, 36a, and 36b and the second cutting guide portions 28a, 28b, 38a, and 38b may be linear or curved.

As mentioned above, the brace 10 is provided with the first cutting guide portions 26a, 26b, 36a, and 36b, so it is easy to cut the brace 10 along the first cutting guide portions 26a, 26b, 36a, 36b, and with the second cutting guide portion 26a, 26b, 36a, and 36b. Cut off at the corresponding position between the minor molar and the first major molar. The suitable period for cutting and using the brace 10 along the first cutting guide portions 26a, 26b, 36a, 36b is from about 5 years old when the user's first molars begin to erupt. With this, from the time when the deciduous teeth from the central incisor to the second molar are aligned, until the permanent teeth from the central incisor to the second molar are aligned, the same type of braces can be used for life.

Moreover, if the brace 10 is provided with the second cutting guide portions 28a, 28b, 38a, and 38b, it is easy to cut the brace 10 along the second cutting guide portions 28a, 28b, 38a, and 38b. The corresponding position between the first molar and the second molar is cut off. This makes it possible to form a brace 10 that is easy to use even before the second molar teeth erupt. The suitable time for cutting and using the dental brace 10 along the second cutting guide parts 28a, 28b, 38a, 38b is when the user is about 7 to 10 years old.

Here, when the upper outer wall 22, the upper inner wall 24, the lower outer wall 32 or the lower inner wall 34 are formed from the central incisor of the base 12 to a position corresponding to the first molar, the first cutting guide 26a , 26b, 36a, and 36b can also be provided on the inner or outer side of the upper outer wall 22, the upper inner wall 24, the lower outer wall 32, or the lower inner wall 34.

Furthermore, when the upper outer wall 22, the upper inner wall 24, the lower outer wall 32, or the lower inner wall 34 are formed to a position corresponding to the end of the base 12, the second cutting guide portions 28a, 28b, 38a, 38b It can also be provided on the inner or outer side of the upper outer wall 22, the upper inner wall 24, the lower outer wall 32, or the lower inner wall 34.

First cutting guides 26a, 26b, 36a, 36b and a second cutting guide 28a are provided on the inner or outer surfaces of the upper outer wall 22, the upper inner wall 24, the lower outer wall 32, or the lower inner wall 34. , 28b, 38a, and 38b, the first cutting guide portions 26a, 26b, 36a, 36b or the second cutting guide portions 28a, 28b, 38a, and 38b may also move toward each other as they move away from the base portion 12, respectively. It is formed by tilting the direction of the central incisors. With this configuration, when the brace 10 is cut along the first cutting guides 26a, 26b, 36a, 36b or the second cutting guides 28a, 28b, 38a, 38b, the upper outer wall 22 and the upper inner wall 24 The lower outer wall 32 and the lower inner wall 34 are difficult to interfere with the inner side of the cheek, the hard palate, and the tongue, so the brace 10 can be formed that is less likely to cause discomfort when worn.

Fig. 5 shows a dental brace 10a according to the first embodiment of the present invention. The parts having the same structure as the brace 10 are marked with the same symbols as the brace 10 . The dental brace 10a is provided with the tongue placement part 40. The tongue placement portion 40 is also shown in Figures 6, 7, and 9, and is provided from the lower inner wall 34 formed to a position corresponding to the end of the base portion 12 or the first molar, to the inner side of the U-shape of the base portion 12, and extends toward the lower jaw. Here, the tongue portion 40 is formed to have a groove 42 in the center (see also FIGS. 5 and 10 ), forming a U-shape in the same direction as the base portion 12 .

In addition, as shown in FIG. 5 , the tongue setting portion 40 is formed with first tongue setting portion cutting guide portions 46a, 46b corresponding to the first cutting guide portions 26a, 26b, 36a, 36b, and second cutting guide portions 46a, 46b corresponding to the first cutting guide portions 26a, 26b, 36a, 36b. The second tongue portion corresponding to the cutting guide portions 28a, 28b, 38a, 38b cuts off the guide portions 48a, 48b. The first tongue setting cutting guides 46a, 46b and the second tongue setting cutting guides 48a, 48b may be connected with the first cutting guides 26a, 26b, 36a, 36b and the second cutting guides 28a, 48b, respectively. 28b, 38a, 38b are set in a continuous manner (refer to Figures 6 and 8). Moreover, as shown in FIG. 10, the 1st tongue setting part cutting guide part 46a, 46b and the 2nd tongue setting part cutting guide part 48a, 48b may be provided on the bottom surface side.

As mentioned above, since the brace 10a is provided with the tongue resting portion 40, the user's tongue is rested on the tongue resting portion 40, whereby the tip of the tongue is easily in contact with the hard palate, which can prevent and improve low tongue position or snoring. At this time, since the tongue placement portion 40 is provided with the groove 42, it is difficult for the genioglossus muscle to interfere. In addition, since the tongue setting portion 40 is provided with the first tongue setting portion cutting guide portions 46a, 46b and the second tongue setting portion cutting guide portions 48a, 48b, it can be cut along the first and second cutting guide portions 26a, 26b, 36a, 36b, 28a, 28b, 38a, 38b and the first and second lingual cutting guide parts 46a, 46b, 48a, 48b, between the second minor molar and the first major molar and the first major molar The brace 10a can be easily cut off at corresponding positions between the second largest molar tooth and the second largest molar tooth. In this way, from the time when the deciduous teeth from the central incisor to the second molar teeth are aligned, to the state before the eruption of the second molar teeth, and from the time when the permanent teeth are aligned from the central incisor to the second molar teeth, it can be used for life. Braces of the same mold 10a.

Here, the thickness of the lingual portion 40 may be gradually thickened toward the central incisor side from the end of the base 12 or the position corresponding to the first molar (see FIGS. 6, 7, and 9). By adopting this structure, the brace 10a can be set so that the tip of the tongue can more easily come into contact with the hard palate.

Furthermore, as shown in FIGS. 5 and 10 , if the groove 42 is configured to expand in the end direction of the base 12 , or the first tongue cutting guides 46 a and 46 b and/or the second tongue cutting guides 46 a and 46 b are used. The guide portions 48a, 48b are configured to be inclined in the direction of the central incisor, and can be easily cut along the first tongue portion cutting guide portions 46a, 46b and/or the second tongue portion cutting guide portions 48a, 48b. This creates a brace that is more difficult to interfere with the genioglossus muscle.

As shown in FIGS. 7 and 8 , the dental brace 10 a has a U-shaped upper outer wall upper cutting guide portion 22 a along the base 12 formed on the upper outer wall 22 . The upper outer wall upper cutting guide 22a can be formed so that the range above the upper outer wall upper cutting guide 22a increases toward the center incisor direction. If the upper outer wall upper part cutting guide 22a is provided, the upper part of the upper outer wall 22 can be easily cut along the upper outer wall upper part cutting guide 22a. Therefore, it is possible to form a relatively small mouth even for children or women. The brace 10a is also easy for the user to wear.

Fig. 11 shows a dental brace 10b according to the second embodiment of the present invention. Since the basic structure of the brace 10b is the same as that of the brace 10a, the differences will be described below. The brace 10b is provided with a U-shaped cutting guide 44 along the base 12 (see FIGS. 5 and 10 ) on the tongue placement portion 40 . The illustration of the illustration is omitted, but the U-shaped cutting guide 44 may be provided on the bottom side. If the structure is provided with the U-shaped cutting guide 44, the tongue setting portion 40 can be easily cut along the U-shaped cutting guide 44, so the brace 10b can be formed that is less likely to interfere with the mandibular protuberance or the like. .

In the case of the braces 10a and 10b described above, the first tongue-setting cutting guides 46a and 46b, the second tongue-setting cutting guides 48a and 48b and the U-shaped cutting guide 44 are grooves. groove. In addition to grooves, these may also be protrusions, protrusions, holes or holes (including those provided continuously), or printed lines or dotted lines. In addition, the first tongue setting portion cutting guide portions 46a, 46b and the second tongue setting portion cutting guide portions 48a, 48b may be linear or curved.

Users of the braces 10a and 10b of the present invention can obtain the following benefits. First of all, the braces 10a and 10b of the same mold manufactured at a relatively low cost can be used for life, so there is no need to customize braces that match the user's dentition, which is more economical. Secondly, by preventing the jaw from moving in the downward direction when the head is raised, the positional deviation of the condyle relative to the skull, especially the mandibular glenoid fossa, can be prevented. This can prevent the onset of temporomandibular joint disease, or the onset of hearing impairment and other symptoms caused by the condyle moving toward the ear hole and compressing the ear hole or mandibular branch, or the surrounding nerves. In addition, by wearing the braces 10a and 10b while sleeping, nasal breathing is given priority, which prevents dryness in the mouth, prevents the proliferation of bacteria or viruses, and also prevents snoring. Especially in the stage of young children when all the deciduous teeth from the central incisor to the second molar have grown together, the state of giving priority to nasal breathing during sleep can promote the growth of the maxillary sinus. Underdevelopment of the maxillary sinus is considered to be one of the causes of overbite or overbite (mandibular protrusion). Therefore, by continuing to use braces 10a and 10b from early childhood, the onset of overbite or overbite can be suppressed. In addition, tooth wear is considered to be one of the causes of aging of the corners of the mouth, such as narrowing of the mouth and wrinkles around the mouth including nasolabial folds. Therefore, by placing braces between the teeth of the upper and lower jaws, the wear of the teeth caused by the friction between the teeth can be prevented, and the aging of the corners of the mouth can also be inhibited.

As described above, according to the present invention, it is possible to provide a dental brace that can be used for a lifetime even if a tooth mold is not taken to make it.
