Description

  The present invention relates to a dental mouthpiece set and a mouthpiece used for periodontal disease treatment and the like.

  In recent years, the importance of oral care for preventing oral infections such as periodontal disease has been reviewed. Periodontal disease is a disease in which gums are inflamed by toxins produced by bacteria in plaque, and the gums swell and bleed. In addition, as the symptoms progress, the alveolar bone that supports the teeth melts, and the teeth sag and fall off. In addition, when inflammation continues, toxins produced by bacteria are carried throughout the body in the bloodstream, leading to various systemic diseases such as cancer and myocardial infarction.

  The basis of periodontal disease prevention is to prevent plaque from sticking, and daily brushing is effective, but in addition to physically removing plaque by brushing, periodic sterilization with drugs is regularly performed. It is desirable to do. Such sterilization is performed by applying a sterilizing and disinfecting agent to the inside of a mouthpiece prepared according to an individual's dentition and mounting it in the oral cavity (see, for example, Patent Document 1). Moreover, in order to effectively sterilize, it is preferable to use a mouthpiece provided with a drug space for holding a drug inside, and such a mouthpiece is prepared as follows, for example. . First, an impression is taken from the inside of the oral cavity of a person to prepare a tooth-shaped gypsum model, and a heated polyethylene sheet is placed on the gypsum model and subjected to pressure molding to create a spacer imitating a dentition. Next, a mouthpiece is created by covering the gypsum model covered with the spacer with a thermoplastic resin sheet such as ethylene vinyl acetate and performing pressure molding. Thus, by creating a mouthpiece using a spacer, a medicine space corresponding to the spacer is formed inside the mouthpiece.

  On the other hand, in the case of a periodontal disease patient with bleeding, it is better not to sterilize with a disinfectant to prevent anaphylactic shock. Therefore, in the treatment of periodontal disease accompanied by bleeding, the inflammation is suppressed by wearing a mouthpiece coated with an antibiotic on the inside, and sterilization using a disinfectant is performed after the bleeding disappears. Here, since the antibiotic is more expensive than the bactericidal disinfectant, the amount of the antibiotic to be used is suppressed by using a mouthpiece provided with a drug space extending along the cervical gingival line.

  In addition, tongue coating is considered to be a hotbed of bacteria, like plaque, and causes bad breath. Tongue moss is a mass of bacteria attached to the surface of the tongue, food waste, etc., when the saliva secretion is low and the mouth is dry, or when the immune system is reduced due to poor physical condition, etc. Tongue increases.

Furthermore, bruxism is one of the causes of worsening periodontal disease. Bruxism refers to clenching or biting teeth, which is performed unconsciously during sleep or the like, and gives excessive addition to the dentition. It is known that excessive addition to the dentition causes root fractures and worsening periodontal disease. As a treatment method for such bruxism, a splint therapy in which a mouthpiece called a splint is attached to a dentition is known (for example, see Patent Document 2). When the splint is attached, the force applied to the dentition is dispersed and the force applied only to a small number of teeth is prevented, and the progression of periodontal disease can be suppressed.

[First Embodiment]
Hereinafter, a dental mouthpiece set according to a first embodiment of the present invention will be described with reference to the accompanying drawings.

  With reference to FIG.1 and FIG.2, the dental mouthpiece set 100 which concerns on this embodiment is equipped with the 1st mouthpiece 1 which can be mounted | worn in the predetermined position in an oral cavity so that the patient's dentition F and the gum G may be covered. And a second mouthpiece 2 that can be mounted at a predetermined position in the oral cavity so as to cover the dentition F and gingiva G of the patient.

  The first mouthpiece 1 is a hollow member formed in a substantially U shape in plan view in accordance with an individual's dentition F and gingiva G. The first mouthpiece 1 has a cervical gingival line (tooth) on the inside of the first mouthpiece 1. A groove portion 11 serving as a drug space extending along the vicinity of the boundary between the row F and the gingiva G is provided in a ring shape and in a line shape. Similarly, the second mouthpiece 2 is a hollow member formed in a substantially U shape in plan view in accordance with the individual dentition F and gingiva G, but the first mouthpiece 1 is located inside the second mouthpiece 2. A medicine space 21 corresponding to the outer shape of the first mouthpiece 1 is provided so that the first mouthpiece 1 can be fitted perfectly inside the second mouthpiece 2 (see FIG. 2C).

  The drug space refers to a space defined between the inside of the mouthpiece and the dentition and gingiva when the mouthpiece is mounted at a predetermined position in the oral cavity. That is, as shown in FIG. 2B, when the second mouthpiece 2 is mounted at a predetermined position in the oral cavity, a medicine space 21 is defined between the second mouthpiece 2 and the dentition F and gingiva G. Particularly in the embodiment, the first mouthpiece 1 can be accommodated in the medicine space 21 as shown in FIG.

  Further, in the vertical direction D1, the depth L2 of the internal space of the second mouthpiece 2 is larger than the height L1 of the first mouthpiece 1, and the first mouthpiece 1 is mounted inside the second mouthpiece 2. In the state, the edge 12 of the first mouthpiece 1 is configured not to be exposed to the outside beyond the edge 22 of the second mouthpiece 2.

  Next, a method for treating periodontal disease accompanied by bleeding will be described. First, an antibiotic is accommodated and held in the groove 11 of the first mouthpiece 1 and is attached to the patient (see FIG. 2A). When the first mouthpiece 1 is mounted in this way, the antibiotic stored and held in the groove 11 is applied to the gingival line of the cervical region, while the inner surface of the first mouthpiece 1 excluding the groove 11 has a dentition F. And the peripheral part Ga of the gingiva G, the antibiotic does not flow out from the first mouthpiece 1 or the saliva does not enter the first mouthpiece 1 and the antibiotic is not diluted, and the affected part is affected by the antibiotic. Can be kept for a long time in the vicinity of the cervical gingival line. Moreover, since an antibiotic can be apply | coated and used for the groove part 11, the quantity of the antibiotic to be used can be suppressed, the cost concerning an antibiotic can be suppressed, and the environmental pollution by an antibiotic can be reduced. In addition, in order to fully exhibit the effect of the antibiotic, it is necessary to wear the first mouthpiece 1 continuously for about 8 hours.

  In addition, as shown in FIG.2 (c), the 2nd mouthpiece 2 can also be mounted | worn with overlapping from the 1st mouthpiece 1, and the 1st mouthpiece 1 and the 2nd mouthpiece 2 are piled up in this way. By using the antibacterial agent, the outflow of antibiotics can be more reliably prevented. In addition, if the first mouthpiece 1 is worn at bedtime at night, the first mouthpiece 1 may be damaged due to bruxism or the like, and an internal antibiotic may flow out. Thus, such a problem can be avoided.

  When inflammation is suppressed by using antibiotics and bleeding stops, bactericides such as periodontitis bacteria and caries bacteria are sterilized using a disinfectant. Specifically, a disinfectant is applied to the inside (drug space 21) of the second mouthpiece 2 and is attached to the patient (see FIG. 2 (b)). When mounted in this manner, the end space 23 of the second mouthpiece 2 is in close contact with the gingiva G to seal the drug space 21, so that the disinfectant may flow out of the second mouthpiece 2 or saliva may 2 The sterilizing / disinfecting agent can be kept in the second mouthpiece 2 for a long time without entering the inside of the mouthpiece 2 and thinning the sterilizing / disinfecting agent. In order to fully exhibit the effect of the disinfectant, the second mouthpiece 2 is worn for about 20 minutes.

  Thus, by using the first mouthpiece 1 and the second mouthpiece 2, even a severe periodontal disease accompanied by bleeding can be effectively treated. In addition, after periodontal disease is completely cured, it is preferable to perform sterilization and sterilization using the second mouthpiece 2 on a daily basis for periodontal disease prevention. Moreover, when periodontal disease recurs, the treatment using the first mouthpiece 1 may be performed again as necessary.

  Next, a method for manufacturing the mouthpiece set 100 will be described. Referring to FIG. 3, an accurate dental mold and a gingival gypsum model K are prepared based on an intraoral impression. Since the preparation method of the plaster model K is well-known, description is abbreviate | omitted. Next, the groove forming member L is linearly provided along the gingival line of the plaster model K. The groove forming member L can be provided by a method in which a photo-curing resin is applied and cured along the cervical gingival line, or a thread-like member such as tako thread or a string-like member is bonded along the cervical gingival line. And the like.

  Next, the first mouthpiece 1 is created using the plaster model K. For example, a heating / pressure molding machine for dental technicians can be used to create the first mouthpiece 1. Here, a case where a heating / pressure molding machine for dental technicians is used will be described as an example. First, the gypsum model K is placed and set on a placing table (not shown) of a heating / pressure molding machine, and the surface S11 of the polyethylene sheet S1 is heated by a heater (not shown). Next, the polyethylene sheet S1 is inverted and the heated surface S11 is opposed to the gypsum model K. In this state, the polyethylene sheet S1 is covered with the gypsum model K, and further, a sealing cover (not shown) is put over and set. . In this state, pressurize and cool, and remove from the plaster model K. Thereafter, unnecessary portions are trimmed to complete the first mouthpiece 1. By creating the first mouthpiece 1 in this manner, the shape of the individual dentition F and gingiva G is accurately reproduced on the first mouthpiece 1 and at the same time the gingival gingiva is formed by the groove forming member L. A line-shaped groove 11 along the line is formed.

  Here, when a groove forming member L is provided on the gypsum model K by adhering a string or a strand along the gingival line of the cervix, the inner surface of the groove 11 is uneven, and the groove 11 is visually recognized by the unevenness. Thus, the antibiotic can be easily applied to the groove 11.

  Next, the second mouthpiece 2 is created using the plaster model K and the first mouthpiece 1. For the production of the second mouthpiece 2, a heating / pressure molding machine for dental technicians can be used. First, the gypsum model K is placed and set on a placing table (not shown) of a heating / pressure molding machine, and the first mouthpiece 1 is set on the gypsum model K. Next, the surface S21 of the thermoplastic resin sheet S2 is heated by a heater (not shown), the thermoplastic resin sheet S2 is inverted, and the heated surface S21 is opposed to the first mouthpiece 1. In this state, the thermoplastic resin sheet S2 is placed on the gypsum model K from the top of the first mouthpiece 1, and further set with a sealing cover (not shown). In this state, it is pressurized and cooled, and is removed from the first mouthpiece 1 and the plaster model K. Thereafter, unnecessary portions are trimmed to complete the second mouthpiece 2.

  By creating the second mouthpiece 2 in this way, the shapes of the individual dentition F and gingiva G are accurately reproduced on the second mouthpiece 2, and the first mouthpiece 1 functions as a spacer. As a result, a medicine space 21 corresponding to the first mouthpiece 1 is formed.

  Thus, in this embodiment, since the spacer for forming the medicine space 21 can be used as the first mouthpiece 1 for antibiotics without destroying the spacer when creating the second mouthpiece 2, the spacer and the antibiotic are used. The manufacturing cost of the dental mouthpiece set 100 can be suppressed as compared with the conventional method of separately preparing the mouthpiece for the agent.

  Here, as the thermoplastic resin sheet S2 used for producing the second mouthpiece 2, for example, an ethylene vinyl acetate (EVA) sheet can be used. Since EVA has flexibility, if the second mouthpiece 2 is made of EVA, the wearer will not feel uncomfortable even if the edge 21 hits the gingiva G when the second mouthpiece 2 is mounted.

  Alternatively, a polycarbonate sheet can be used as the thermoplastic resin sheet S2. By making the second mouthpiece 2 made of polycarbonate, it is possible to reduce the weight of the second mouthpiece 2 as compared to the case of making it made of EVA, and its thickness (from the outer surface to the inner surface of the second mouthpiece 2). (Distance) can be made thinner, and the uncomfortable feeling when worn can be reduced. For example, the second mouthpiece 2 made of EVA requires a thickness T1 of about 3 mm due to the durability problem, and it is difficult to attach the upper jaw and the lower jaw at the same time, but the second mouthpiece 2 made of polycarbonate is thicker The length T1 can be set to 0.5 mm to 1.0 mm, and simultaneous mounting on the upper jaw and the lower jaw is possible. Further, in the case of polycarbonate, even if it is used repeatedly over a long period of time, it does not change color, has good cleanability, and can be used cleanly.

  In addition, when there are missing teeth in the dentition F, the dentition F becomes discontinuous, but in this case as well, the first mouthpiece 1 and the second mouthpiece 2 correspond to the shape of the discontinuous dentition F. Is preferably formed. In this case, the groove 11 provided in the first mouthpiece 1 can be discontinuous as necessary.

  Also, if a plurality of first mouthpieces 1 are prepared in advance, when the first mouthpiece 1 is damaged or the dirt becomes severe, only the first mouthpiece 1 can be replaced and used. Similarly, if a plurality of second mouthpieces 2 are prepared in advance, when the second mouthpiece 2 is damaged or the dirt becomes severe, only the second mouthpiece 2 can be replaced and used. .

[Second Embodiment]
Next, a dental mouthpiece set according to the second embodiment of the present invention will be described. In addition, in the following embodiment, the same reference number is attached | subjected to the thing substantially the same as 1st Embodiment mentioned above, and the description is abbreviate | omitted.

  Referring to FIG. 5, the mouthpiece set 100 </ b> A according to the present embodiment is for the upper jaw, and is placed at a predetermined position in the oral cavity so as to cover the first mouthpiece 1 and the patient's dental row F and gum G. A second mouthpiece 2A that can be mounted. The second mouthpiece 2 </ b> A includes a substantially U-shaped tooth row portion 24 and a tongue contact portion 25 fixed to the tooth row portion 24. The dentition portion 24 has the same configuration as the second mouthpiece 2 described above. That is, the dentition portion 24 is formed in a substantially U shape in accordance with the individual dentition F and gingiva G, and a drug space 21 corresponding to the outer shape of the first mouthpiece 1 is provided on the inside thereof. Thus, the first mouthpiece 1 can be fitted perfectly inside the second mouthpiece 2A (dentation portion 24).

  The tongue contact portion 25 is made of a porous member such as a sponge, for example, and is fixed to the dentition portion 24 so as to seal a U-shaped space portion by the dentition portion 24. Moreover, the height dimension of the tongue contact part 25 in the up-down direction D1 is set so as to gradually increase toward the inner side of the oral cavity. When such a second mouthpiece 2A is mounted at a predetermined position in the oral cavity, the dentition portion 24 covers a part of the maxillary dentition F and gingiva G, and the tongue contact portion 25 is in the vertical direction D1. Facing the tongue (not shown).

  By using such a second mouthpiece 2A, it is possible to sterilize bacilli such as periodontal disease bacteria present in the dentition F and gingiva G as well as the second mouthpiece 2 described above, and also clean the tongue. Can do. That is, when the disinfectant is soaked in the tongue contact portion 25 of the second mouthpiece 2A, the second mouthpiece 2A is attached to the upper jaw, and the tongue is rubbed against the tongue contact portion 25 in this state, The tongue coating is physically removed by the contact portion 25, and gonococci such as periodontal disease bacteria present on the surface of the tongue can be sterilized by the bactericidal disinfectant soaked in the tongue contact portion 25. Moreover, since the height dimension of the tongue contact part 25 is set so as to increase toward the back side in the oral cavity, the entire tongue including the back part of the tongue can be applied to the tongue contact part 25. The entire tongue is easily cleaned.

  The second mouthpiece 2A is created as follows. First, the dentition portion 24 is created by the same method as the second mouthpiece 2 described above. Next, the tongue contact portion 25 is attached to the tooth row portion 24 so as to close the U-shaped portion of the tooth row portion 24. For attaching the tongue contact portion 25 to the dentition portion 24, for example, an immediate polymerization resin used as a denture correction agent can be used as an adhesive.

  Thus, according to the 2nd mouthpiece 2A in this embodiment, the stain | pollution | contamination of a tongue is physically and chemically removed at the same time it sterilizes aspergillus etc. which exist in the dentition F and the gum G. can do. Moreover, since it only needs to be installed in the oral cavity, the oral cavity can be easily kept clean even when the user cannot use a toothbrush like a care recipient.

  In addition, the tongue contact part 25 is not limited to a sponge member, may be comprised from another member, for example, the brush member by which many brush hairs were implanted may be sufficient. When the tongue contact portion 25 is formed of a brush member, when the second mouthpiece 2A is mounted on the upper jaw, the tip of the brush hair is directed downward, and the length of the brush hair is set to the inner side of the oral cavity. What is necessary is just to make it increase gradually as it goes. In this case, by using a gel-like disinfectant, the disinfectant can be held on the brush member without dripping.

  Further, the tongue contact portion 25 of the second mouthpiece 2A may include water or artificial saliva instead of the medicine, and may be worn at bedtime. Depending on the drug administered, the secretion of saliva may be suppressed as a side effect. When such a side effect occurs, the oral cavity and lips may dry out at bedtime and may cause discomfort, but the second mouthpiece 2A Such discomfort can be reduced by attaching water or artificial saliva to the tongue abutting portion 25.

  In addition, although the 2nd mouthpiece 2A of this embodiment is for upper jaws, you may provide a tongue contact part in the 2nd mouthpiece for lower jaws. In this case, when the second mouthpiece is mounted on the lower jaw, the dentition portion covers the lower dentition and part of the gingiva, and the tongue contact portion faces the tongue in the vertical direction. Good.

[Third Embodiment]
Next, a dental mouthpiece set according to a third embodiment of the present invention will be described. With reference to FIG. 6, the dental mouthpiece set 100B according to the present embodiment includes the first mouthpiece 1 (see FIG. 1) and the second mouthpiece 2B described above. The second mouthpiece 2B has substantially the same configuration as the second mouthpiece 2 described above, but differs in that artificial teeth 26 are provided corresponding to the missing teeth. More specifically, the 2nd mouthpiece 2B adheres to the mouthpiece main body 27 produced in the substantially U shape according to the personal dentition F and the gingiva G, and the location corresponding to the missing tooth of the mouthpiece main body 27. One or a plurality of artificial teeth 26. Inside the second mouthpiece 2B (mouthpiece body 27), a medicine space 21 (see FIG. 2B) corresponding to the outer shape of the first mouthpiece 1 is provided, whereby the inside of the second mouthpiece 2B. In addition, the first mouthpiece 1 is configured to be fitted perfectly.

  Thus, since the second mouthpiece 2B of the present embodiment is provided with the artificial teeth 26 corresponding to the missing teeth, the second mouthpiece 2B can be stably mounted. In other words, if there is a missing tooth and a second mouthpiece that does not have artificial teeth 26 is mounted, the teeth are incompletely meshed and the second mouthpiece tends to float with respect to the dentition F. This causes the disinfectant to leak from the second mouthpiece. On the other hand, by providing the artificial tooth 26, the meshing of the teeth can be improved, the mounting property of the second mouthpiece 2B can be improved, and the leakage of the sterilizing / disinfecting agent can be more reliably prevented.

  Here, the mouthpiece body 27 is preferably made of polycarbonate. By making the product made of polycarbonate, the shape is stabilized instead of lacking flexibility as compared with the product made of EVA. Therefore, the artificial tooth 26 can be easily and firmly secured using the above-mentioned adhesive such as an immediate polymerization resin. The main body 27 can be adhered.

[Fourth Embodiment]
Next, a dental mouthpiece according to a fourth embodiment of the present invention will be described. Referring to FIG. 7 (a), the illustrated mouthpiece 3 is made of polycarbonate, made in a substantially U shape in accordance with the individual's dentition F and gingiva G, and mounted at a predetermined position in the oral cavity. In this case, a part of the dentition F and the gingiva G is covered so as to be accommodated in the internal space. The mouthpiece 3 is provided with a medicine space 34. When the mouthpiece 3 is mounted at a predetermined position, the medicine space 34 is defined between the inner surface 31 of the mouthpiece 3 and the outer surfaces of the dentition F and the gingiva G. At the same time, the drug space 34 is sealed by the end edge portion 32 closely contacting the gum G. Accordingly, by applying a medicine such as a sterilizing and disinfecting agent to the inner surface 31 of the mouthpiece 3 and mounting it in the oral cavity, periodontal disease bacteria and the like can be killed by the sterilizing and disinfecting effect of the medicine.

  Although the mouthpiece 3 has substantially the same configuration as the second mouthpiece 2 described above, the mouthpiece 3 is particularly a solid line from the original position where the gingiva G is indicated by a two-dot chain line as shown in FIG. It is lowered to the position shown, and is preferably used when a part of the tooth root Fc is exposed from the gingiva G. In other words, 8020 exercise (exercise to leave more than 20 teeth at the age of 80) has increased the percentage of people who still have their teeth even when they are older, but most of them are due to gum decay. The tooth root Fc is exposed from the gingiva G. Root Fc covered with cementum becomes caries not only by sugar but also by carbohydrates, but as it gets older, it tends to become a soft and chewable carbohydrate-based diet. It is effective to apply, and the mouthpiece 3 in this embodiment can be effectively used for such fluoride application.

  More specifically, the mouthpiece 3 is located on the top side of the tooth Fa with respect to the maximum bulge portion (hereinafter, simply referred to as “maximum bulge portion”) based on the attachment / detachment direction D3 (usually the vertical direction D1) of the mouthpiece 3. It has the 1st part 3A located in the (occlusion surface side), and the 2nd part 3B located in the gum G side rather than the largest swelling part of the tooth Fa.

  The first portion 3A is opposed to the range from the maximum bulge portion of the tooth Fa to the crown, and the second portion 3B is a region on the gingival G side from the maximum bulge portion of the tooth Fa including the root Fc portion exposed from the gingiva G. It faces a part of the gingiva G. In the width direction D2 (the direction from the cheek side or the lip side toward the tongue side or the palate side), the minimum inner dimension of the second portion 3B of the mouthpiece 3 is the projected dimension of the tooth Fa in the attachment / detachment direction D3 of the mouthpiece 3 T2 or more.

  Thus, since the mouthpiece 3 is made of polycarbonate, as described above, the thickness T1 (the thickness of the first portion 3A and the thickness of the second portion 3B) is 0.5 mm to 1.0 mm. It can be attached to the upper jaw and the lower jaw simultaneously and can be used cleanly over a long period of time. Note that if the thickness of the mouthpiece T1 is less than 0.5 mm, durability may be impaired and it may not be able to withstand long-term use. If the thickness T1 exceeds 1.0 mm, simultaneous application to the upper jaw and lower jaw Wearing may be difficult.

  Further, in the width direction D2, the minimum inner dimension of the second portion 3B of the mouthpiece 3 is equal to or larger than the projection dimension T2 of the tooth Fa. Therefore, even if the mouthpiece 3 is made of polycarbonate, it can be moved to a predetermined position in the oral cavity. It can be easily attached and detached. That is, since the mouthpiece 3 made of polycarbonate does not expand and contract unlike the mouthpiece made of EVA, for example, the minimum inner dimension of the second portion 3B of the mouthpiece 3 is set from the projection T2 of the tooth Fa according to the width dimension of the root Fc. However, when the mouthpiece 3 is attached / detached, the second portion 3B cannot get over the maximum bulge portion of the tooth Fa, but the minimum inner dimension of the second portion 3B should be equal to or greater than the projected dimension T2 of the tooth Fa. Thus, such a problem can be avoided.

  The mouthpiece 3 can be created as follows, for example. Referring to FIG. 8, an individual's accurate tooth shape and gingival gypsum model K1 are prepared by an intraoral impression (preparation process). Next, a survey is performed on the plaster model K1, and a survey line is drawn on the teeth K11 and the gingiva K12 of the plaster model K1. Thus, the survey line (first survey line) drawn on the tooth K11 shows the maximum bulge of the tooth K11 (tooth Fa), and the survey line (second survey line) drawn on the gingiva K12 is a mouse. The projection line of the tooth K11 in the attachment / detachment direction D3 of the piece 3 is shown. Next, the putty P is placed in a predetermined range to adjust the gypsum model K1, and an adjusted gypsum model K1 'is created (adjustment process). The predetermined range in which the putty P is piled up includes at least the range R3 to the first survey line and the second survey line, and the thickness in the width direction D2 of the adjusted plaster model K1 ′ in this range R3 is the maximum bulge portion. The projected dimension T2 or more is set. Then, using the adjusted gypsum model K <b> 1 ′, a spacer is created by the same procedure as that for the first mouthpiece 1 described above. That is, a preheated uniform thickness polyethylene sheet is placed on the adjusted gypsum model K1 ', covered with a sealing cover, pressurized and cooled, and removed from the gypsum model K1'. Thereafter, a spacer made of polyethylene is completed by trimming unnecessary portions (spacer creation step). Next, the mouthpiece 3 is created in the same procedure as the above-described second mouthpiece 2 by using the spacer thus created and the adjusted gypsum model K1 '. That is, the adjusted gypsum model K1 'is covered with a spacer, and a preheated polycarbonate sheet (thermoplastic resin sheet) is put on the adjusted gypsum model K1' from above the spacer. Cover with a sealing cover, pressurize and cool, and remove from the spacer and adjusted gypsum model K1 '. Thereafter, the mouthpiece 3 is completed by trimming unnecessary portions (mouthpiece forming step).

[Fifth Embodiment]
Next, a dental mouthpiece according to a fifth embodiment of the present invention will be described. Referring to FIG. 9, the illustrated mouthpiece 4 is a dental mouthpiece made of polycarbonate that can be mounted at a predetermined position in the oral cavity so as to cover the dentition F and the gingiva G, and is substantially the same as the above-described mouthpiece 3. Have the same configuration. However, in the mouthpiece 4 of the present embodiment, when the mouthpiece 4 is mounted at a predetermined position in the oral cavity, the tip portion 41 abuts on the crown of the crown Fb (dentition F), and the edge portion 42 is A drug space 44 is defined by an intermediate portion 43 that is in close contact with the gingival G and is located between the distal end portion 41 and the end edge portion 42, and is configured so that a drug (such as a disinfectant) can be held in the drug space 44. This is different from the mouthpiece 3 described above. The mouthpiece 4 having such a configuration is also preferably used when the position of the gingiva G is lowered due to gingival decay and a part of the root Fc is exposed from the gingival G as shown in FIG.

  That is, in a state where a part of the tooth root Fc is exposed as described above, the tooth Fa is not sufficiently supported by the gum G, and the tooth Fa is wobbled. When the mouthpiece 3 shown in FIG. 7 (a) is mounted in such a state that the tooth Fa is wobbled, the mouthpiece 3 is supported with its end edge portion 32 in close contact with the gum G. In this case, the mouthpiece 3 is not sufficiently supported, and the mouthpiece 3 may be wobbled to cause pain in the wearer.

  On the other hand, in the mouthpiece 4 of the present embodiment, the distal end portion 41 and the end edge portion 42 are supported by being in contact with and closely attached to the crown Fb and the gingiva G, respectively. So that the wearer does not experience pain. In addition, since the mouthpiece 4 is made of polycarbonate, for example, the shape of the mouthpiece 4 is more stable than when the mouthpiece 4 is made of a vinyl-based material. Can be stably fixed at a predetermined position.

  Here, in the dentition F and gingiva G of the wearer covered with the mouthpiece 4, from the top of the crown Fb to the maximum bulge of the tooth Fa (maximum bulge with reference to the mounting direction D3 of the mouthpiece 4). Is the first region R1, and the region from the maximum bulge portion of the tooth Fa to the edge 45 of the mouthpiece 4 is the second region R2, the tip 41 of the mouthpiece 4 is in close contact with the first region R1. It is preferable to configure as described above. With such a configuration, the mouthpiece 4 can be mounted stably and easily. However, when the tooth Fa extends obliquely with respect to the gingiva G, it is difficult to attach the mouthpiece 4 if the distal end portion 41 of the mouthpiece 4 is in close contact with the entire first region R1. In such a case, the distal end portion 41 may be configured to be in contact with at least the crown of the dentition F.

  Also in this embodiment, about the site | part corresponding to 2nd area | region R2 among the mouthpieces 4, the mouthpiece 4 is set by making the minimum inner dimension in the width direction D2 more than the projection dimension T2 of the largest bulging part of the tooth Fa. Can be easily attached and detached.

  In addition, the mouthpiece 4 can be manufactured by omitting the spacer preparation process from the manufacturing process of the mouthpiece 3 described above, and directly applying a heated polycarbonate sheet to the adjusted gypsum model K1 'and applying pressure and cooling.

[Sixth Embodiment]
Next, a dental mouthpiece according to a sixth embodiment of the present invention will be described. Referring to FIG. 10, the mouthpiece 5 in the present embodiment is configured to be able to scrape the dentition F and the gingiva G, and particularly suitable when a part of the root Fc is exposed from the gingival G due to gingival attenuation. Used for. Specifically, the mouthpiece 5 includes a mouthpiece body 51 having a substantially U shape in plan view that covers a part of the dentition F and the gingiva G when mounted at a predetermined position in the oral cavity, and an inner surface of the mouthpiece body 51. And a rubbing member 52 disposed on the surface. Since the mouthpiece body 51 has the same configuration as the mouthpiece 3 in the above-described fourth embodiment, a detailed description thereof is omitted.

  The rubbing member 52 is made of, for example, a foamed resin, a nonwoven fabric, a brush member, and the like, and includes a first portion 52a that faces the first region R1 and a second portion 52b that faces the second region R2. In the direction perpendicular to the inner surface 51a of the mouthpiece body 51, the second portion 52b is formed thicker than the first portion 52a. Therefore, as shown in FIG. 10, even if the distance from the inner surface 51a of the mouthpiece body 51 to the surface of the tooth Fa or gingiva G is not constant, the rubbing member is applied to almost the entire first region R1 and second region R2. 52 can be brought into contact. Moreover, the 2nd site | part 52b is comprised with the softer material than the 1st site | part 52a. Therefore, even when the second part 52b is configured to be thicker than the first part 52a and the minimum inner dimension of the second part 52b in the width direction D2 is smaller than the projected dimension T2 of the maximum bulge portion of the tooth, the mouthpiece 5 can be attached and detached. Sometimes, the second part 52b can easily get over the maximum bulge portion of the tooth Fa, and the mouthpiece 5 can be easily attached and detached.

  The mouthpiece 5 configured as described above is used as follows. First, the mouthpiece 5 is attached to a predetermined position (upper jaw or / and lower jaw) in the oral cavity. Then, the inner surface of the scraping member 52 comes into contact with a part of the dentition F and the gingiva G, and the edge 53 of the mouthpiece body 51 is in close contact with the gingival G.

  Next, the upper and lower dentitions are bitten. Then, the rubbing member 52 that contacts the crown of the dentition is compressed, and the entire mouthpiece 5 moves to the gingival G side. Further, when the occlusion of the upper and lower dentitions is released, the compression of the rubbing member 52 is released, the original thickness is restored, and the entire mouthpiece 5 moves in the opposite direction. Thus, when the mouthpiece 5 moves relative to the dentition F and the gingiva G, the dentition F and the gingiva G are scraped by the scraping member 52. By rubbing the dentition F in this way, the surface of the dentition F can be polished and the dentition F can be cleaned, and when the gingiva G is rubbed, the gingival G is tightened by the fretting stimulus effect, and the periodontal pocket is formed. The growth of periodontal disease bacteria and the like can be suppressed by reducing the size.

  Thus, according to the mouthpiece 5 in the present embodiment, the thickness of the second portion 52b of the scraping member 52 corresponding to the second region R2 is made larger than the thickness of the first portion 52b corresponding to the first region R1. Therefore, even when the gum G is lowered and a part of the root Fc thinner than the crown Fb is exposed from the gum G, the scraping member 52 is surely brought into contact with the gum G or the exposed root Fc. Therefore, the teeth Fa and the gum G can be reliably scratched. Further, in the scraping member 52, the second part 52b is made of a material softer than the first part 52a to facilitate attachment / detachment of the mouthpiece 5, and at the same time, the first part 52a is more rigid than the second part 52b. By configuring with a material, the mouthpiece 5 can be made difficult to come off. That is, if the first part 52a is made of a soft material like the second part 52b, the mouthpiece 5 is easily detached when the mouthpiece 5 is attached and the upper and lower teeth are repeatedly bitten. Such a problem can be avoided by configuring 52a with a material having higher rigidity than that of the second portion 52b.

  In addition, in order to make mounting | wearing of the mouthpiece 5 easier, you may provide the some slit (not shown) extended in the up-down direction D1 in the 2nd site | part 52b of the abrasion member 52. FIG. Further, the scraping member 52 can be used by containing a medicine. Even in this case, since the edge 53 of the mouthpiece body 51 is in close contact with the gingiva G, the medicine can be prevented from leaking out of the mouthpiece 5.

  Further, a plurality of protrusions may be provided on the inner surface 51a of the mouthpiece body 51, and the tooth row F and the gingiva G may be scraped by these protrusions.

[Seventh Embodiment]
Next, a mouthpiece according to a seventh embodiment of the present invention will be described. Referring to FIG. 11, the mouthpiece 6 according to the present embodiment has substantially the same configuration as the second mouthpiece 2 described above, but the medicine space 64 of the mouthpiece 6 is the medicine space of the second mouthpiece 2. It differs in that it is provided wider than 21. The mouthpiece 6 is mainly used for children, and by providing such a relatively wide drug space 64, the mouthpiece 6 can be used continuously even if teeth are replaced from a deciduous tooth to a permanent tooth. Can do.

  The mouthpiece 6 has a main body 62 that defines a drug space 64 between an end edge portion 63 that is in close contact with the gingiva G when mounted in a predetermined position and a tooth row F that is provided continuously with the end edge portion 63. The mouthpiece 6 can be produced in the same manner as the mouthpiece 3 described above. First, referring to FIG. 12, an accurate tooth shape and a gingival gypsum model K2 of an individual are prepared by an intraoral impression (preparation process). Next, survey is performed on the plaster model K2, and a first survey line is marked on the surface of the tooth K2 of the plaster model K2, and a second survey line is marked on the surface of the plaster model K2. Next, the gypsum model K2 is adjusted by placing the putty P in a predetermined range on the surface of the gypsum model K2, and a finished gypsum model K2 'is prepared (adjustment process). The predetermined range where the putty P is accumulated includes at least the range R3 to the first survey line and the second survey line, and the thickness in the width direction D2 of the adjusted plaster model K2 ′ in this range R3 is the maximum bulge portion. The projected dimension T2 or more is set. In addition, when the size of the permanent teeth that can be estimated can be estimated, it is preferable that the putty P is thickened more or the putty P is piled up in a wider range to deal individually. Further, with regard to the maxillary incisor, since permanent teeth generally grow inside the deciduous teeth, the inner side (lingual side or palate side) of the plaster model K2 in the width direction D2 than the outer side (cheek side or lip side). ) It is preferable to put more putty P, and for maxillary canines, since permanent teeth generally grow outside the deciduous teeth, more putty P is put on the outside than the inside of the plaster model K2 in the width direction D2. Is preferred.

  Thereafter, a spacer is created using the adjusted gypsum model K2 ′, and the mouthpiece 6 is further created using the spacer and the adjusted gypsum model K2 ′. These procedures are the same as those in the fourth embodiment described above. Since it is the same, description is abbreviate | omitted.

  Thus, since the mouthpiece 6 according to the present embodiment is provided with a relatively wide drug space 64 corresponding to the thickness of the spacer and the putty P, the mouthpiece 6 can be used even if the mouthpiece 6 is replaced with a permanent tooth larger than the deciduous tooth. The mouthpiece 6 can be used for a long period of time.

  In addition, when milk teeth and permanent teeth are mixed in the dentition F, the width (first width) of the drug space 64 at the position corresponding to the milk teeth in the width direction D2 is set as the drug at the position corresponding to the permanent teeth. The space 64 may be wider than the width (second width). In this case, it is only necessary to put the putty P only on the tooth K21 corresponding to the deciduous tooth among the plurality of teeth K21 of the plaster model K2, and by creating the mouthpiece 6 in this way, the portion corresponding to the permanent tooth is a spacer. The medicine space 64 corresponding to the thickness of the teeth can be provided, and the medicine space 64 corresponding to the thickness of the spacer and the putty P can be provided at the location corresponding to the milk teeth.

[Eighth Embodiment]
Next, a mouthpiece according to the eighth embodiment of the present invention will be described. Referring to FIGS. 13 to 15, the illustrated mouthpiece 7 has substantially the same configuration as the above-described mouthpiece 4, but the mouthpiece 7 is particularly firmly held in the dentition F by a healthy gingiva G. A tooth Fa in which the root Fc is not exposed (hereinafter referred to as “first tooth Fa”) and a tooth Fa in which a part of the root Fc is exposed from the gum G due to gingival decay (hereinafter referred to as “second tooth Fa”). In the same way as the second mouthpiece 2 described above, the first tooth Fa defines the drug space 74 around the entire crown Fb, while the first tooth Fa As with the mouthpiece 4 described above, the second tooth Fa ′ is configured to contact at least the top of the second tooth Fa ′. In other words, in a state in which the mouthpiece 7 is mounted at a predetermined position in the oral cavity, the tip 71 is not in contact with the top of the first tooth Fa, and between the top of the first tooth Fa. While defining the medicine space 74, it abuts on the top of the second tooth Fa '.

  The mouthpiece 7 is formed as follows, for example. Here, it is assumed that the left first tooth and the left second tooth correspond to the second tooth Fa '. First, an individual's accurate dental mold and gingival gypsum model are prepared based on an intraoral impression, and only a portion corresponding to the first tooth Fa ′ on the surface of the gypsum model is put into a predetermined range and adjusted gypsum. Create a model. The predetermined range where the putty is piled up includes the range (R3) from the first survey line to the second survey line of the gypsum model as in the fourth embodiment described above, and the adjusted gypsum model in this range (R3) The thickness in the width direction D2 is set to be equal to or greater than the projected dimension (T2) of the maximum bulge portion (see FIG. 8).

  And spacer SP (FIG. 16) is created in the procedure substantially the same as the 1st mouthpiece 1 mentioned above using the adjusted plaster model. That is, a preliminarily heated polyethylene sheet having a uniform thickness is placed on the adjusted gypsum model, covered with a sealing cover, pressurized and cooled to form a spacer intermediate P, which is removed from the adjusted gypsum model. . After that, in the spacer intermediate P, the lower end Pa indicated by the dotted line and the upper end Pb corresponding to the upper end of the second tooth Fa ′ are cut out to create the spacer SP. By cutting off the upper end Pb in this way, an opening is formed on the upper surface of the spacer SP, and when the spacer SP is put on the adjusted gypsum model, it corresponds to the top of the second tooth Fa ′ of the adjusted gypsum model. A portion to be exposed is exposed from the spacer SP through the opening. In addition, it is preferable that the upper end Pb to be excised is from the maximum bulge portion of the second tooth Fa ′ to the top of the head, but when the second tooth Fa ′ is growing obliquely, the vicinity of the top of the head It is good only as well. Next, the mouthpiece 7 is created in the same procedure as the second mouthpiece 2 described above using the spacer SP and the adjusted gypsum model thus created.

  As described above, the mouthpiece 7 contacts the crown of the second tooth Fa ′ from which the tooth root Fc is exposed, thereby suppressing the wobble of the second tooth Fa ′, while maintaining the first held by the healthy gum G. The tooth Fa can be sterilized over a wider range by providing a medicine space between the crown and the mouthpiece 7.

[Ninth Embodiment]
Next, a mouthpiece according to the ninth embodiment of the present invention will be described. Referring to FIG. 17, the illustrated mouthpiece 8 includes a mouthpiece body 81 and an elastic member 85 provided on the inner surface of the mouthpiece body 81. The mouthpiece body 81 has substantially the same configuration as that of the mouthpiece 2 described above, and is created according to the individual's dental row F and gum G. The elastic member 85 is preferably configured to have an elastic porous member such as a sponge member, and is disposed on the inner peripheral edge of the mouthpiece body 81. When the mouthpiece 8 is mounted at a predetermined position in the oral cavity, the gum G It is elastically pressed against.

  With this configuration, the mouthpiece 8 can be continuously used even if the gum G is thinned or swelled. That is, when the tooth Fa forming the dentition F is lost, the gum G supporting the missing tooth Fa is thinned. Further, as periodontal disease progresses, the gingiva G is attenuated and thins. In this way, when the gingiva G is thinner than the original, for example, when the mouthpiece 2 described above is attached, a gap is generated between the gingival G and the edge 23 of the mouthpiece 2, and the medicine is the drug space 21. The problem of leaking out occurs. However, in the case of the mouthpiece 8 including the elastic member 85, even if the gingiva G is thinner than the original, the elastic member 85 causes the elastic member 85 to provide a gap between the edge 83 of the mouthpiece body 81 and the gingival G. Since it is sealed, it is possible to prevent the medicine from leaking out from the medicine space 84.

  On the other hand, when the dentition Fa is changed from a milk tooth to a permanent tooth, the gingiva G swells. Moreover, when the periodontal disease is completely cured, the thin gingiva G also swells to its original state. When the mouthpiece 2 described above is mounted in a state where the gingiva G is swollen from the beginning as described above, the swollen gingival G is excessively pressed by the mouthpiece 2 or the mounting itself may be difficult in some cases. End up. However, if it is the mouthpiece 8 provided with the elastic member 85, the elastic member 85 will be elastically compressed and the burden to the swollen gum G can be reduced.

  Moreover, if the elastic member 85 is comprised from an elastic porous member, a chemical | medical agent can be hold | maintained at the elastic member 85, and the gingival G part which the elastic member 85 contacts can be sterilized.

  Such a mouthpiece 8 can be manufactured as follows, for example. First, an impression is taken from an individual's oral cavity to prepare a dental plaster model (K, see FIG. 3), and a spacer is created using this plaster model. That is, a heated polyethylene sheet is placed on a gypsum model, and a hermetic cover is placed on the model, and after pressing, it is cooled to trim unnecessary portions. Next, a spacer is placed on the plaster model, and an elastic sheet made of a sponge material or the like is placed thereon. The heated thermoplastic resin sheet is placed on the plaster model from the top of the elastic sheet, set with a hermetic cover, pressurized and cooled. Thereby, the intermediate mouthpiece MP (FIG. 18) having the elastic sheet fixed inside is completed. Next, the elastic member 85 is completed by excising the upper end portion Pc of the intermediate mouthpiece MP. Then, the elastic member 85 is set on the plaster model, and the mouthpiece 8 is created in the same procedure as the mouthpiece 2 described above. That is, the heated thermoplastic resin sheet is placed on the plaster model from above the elastic member 85, set with a hermetic cover, cooled after pressurization, and unnecessary portions are trimmed. Thereby, the mouthpiece 8 with the elastic member 85 fixed inside is completed.

[Tenth embodiment]
Next, a mouthpiece according to the tenth embodiment of the present invention will be described. Referring to FIG. 19, the illustrated mouthpiece 9 also has a function as a splint used for treatment of bruxism or the like, and a mouthpiece body 91 and a splint portion 96 disposed on the top of the mouthpiece 91. And comprising. The mouthpiece body 91 has substantially the same configuration as that of the mouthpiece 2 described above, and is created according to the individual's dental row F and gum G. The splint portion 96 has a substantially flat occlusal surface 96a.

  When such a mouthpiece 9 is attached to a predetermined position (usually the upper jaw) in the oral cavity, the occlusal surface 96a of the sprint portion 96 is substantially flat. It can move smoothly without being obstructed, can prevent excessive addition to the dentition F, and can be used to treat bruxism. In addition, a drug space is defined between the mouthpiece 9 (mouthpiece body 91) and the dentition F and gingiva G, and the inner peripheral edge of the mouthpiece 9 is in close contact with the gingival G so that the drug space is sealed. Stopped. Therefore, as in the case of the first embodiment described above, periodontal disease bacteria and the like present in the dentition F and the gingiva G can be sterilized and sterilized by accommodating and holding the drug in the drug space. Moreover, since the inner surface of the mouthpiece 9 can be sterilized at the same time, the mouthpiece 9 can be kept clean.

  The mouthpiece 9 can be created as follows, for example. First, the mouthpiece body 91 is created by the same method as the mouthpiece 2 described above. By creating the mouthpiece body 91 in this way, the inner surface of the mouthpiece body 91 has a shape corresponding to the shape of the dentition F and the gingiva G. Next, a room temperature polymerization resin (for example, “Facet Resin” manufactured by GC Corporation) is placed on the upper surface of the mouthpiece body 91 to make the surface flat and harden. Thereby, the mouthpiece 9 having the sprint portion 96 fixed to the mouthpiece body 91 is completed. Thereafter, the mouthpiece 9 is actually attached to the patient and the occlusal surface 96a is finely adjusted.

  Here, the mouthpiece body 91 is preferably made of polycarbonate. Since the shape of the mouthpiece main body 91 is stabilized by being made of polycarbonate, it is possible to prevent the mouthpiece main body 91 from being deformed and the sprint unit 96 from falling off the mouthpiece main body 91.

  In addition, although the mouthpiece 9 in this embodiment has a medicine space, it is not necessary to provide a medicine space. When no medicine space is provided, the mouthpiece 9 is in close contact with both the dentition F and the gingiva G. Even in this case, the mouthpiece 9 can be applied by applying the medicine to the inner surface of the mouthpiece 9. The sterilizing and disinfecting effect by the applied medicine can be obtained.

  As mentioned above, although the dental mouthpiece set and the dental mouthpiece which concern on embodiment of this invention were demonstrated with reference to attached drawing, this invention is not limited to this embodiment, and deviates from the scope of the present invention. Various modifications or corrections are possible.

  For example, the tongue contact portion 25 of the second embodiment may be attached to the second mouthpieces 2 and 2B of the first and third embodiments and the mouthpieces 3 to 9 of the fourth to tenth embodiments. Moreover, the medicine space 21 can be omitted from the second mouthpiece 2A of the second embodiment, and the mouthpiece can be configured as a mouthpiece dedicated to tongue cleaning. Furthermore, you may provide the artificial tooth 26 corresponding to a missing tooth in the mouthpieces 3-9 of 4th-10th embodiment.

  The first mouthpiece 1, the second mouthpiece 2 (2A, 2B), and the mouthpieces 3 to 9 can be used for the treatment or prevention of periodontal disease, as well as for whitening treatment, and sports. It can be used as a mouth guard or night guard.

  In particular, if the mouthpiece set 100 of the first embodiment (the first mouthpiece 1 set inside the second mouthpiece 2) is used as a sports mouth guard, the dirt on the first mouthpiece 1 becomes severe. In some cases, only the first mouthpiece 1 can be replaced and used, and the sports mouth guard can be cleaned. In other words, athletes often take sports drinks that contain a lot of sugar during practice or at the time of a game. By using a sports mouth guard having a double structure of the first mouthpiece 1 and the second mouthpiece 2, only the first mouthpiece 1 can be exchanged and used. In addition, when using as a sports mouth guard, the groove part 11 of the 1st mouthpiece 1 can be abbreviate | omitted.

  In addition, the night guard tends to have holes due to bruxism, and the night guard with holes is generally discarded, but the mouthpiece set 100 of the first embodiment (the first mouthpiece 1 is replaced with the second mouthpiece). 2) is used as a night guard. Even if the night guard (first and second mouthpieces 1 and 2) is perforated by bruxism, only the first mouthpiece 1 is replaced. Can be used.

  In addition, the mouthpiece in each of the above embodiments can be manufactured using a heating / pressure molding machine for dental technicians as described above, and can also be manufactured using a 3D printer. May be manufactured based on the accurate tooth mold and gingival 3D data obtained by.
