FIG. 4 is a perspective view schematically showing a configuration of an apparatus for measuring a magnetic field generated due to electric power generated by the piezoelectric element in the second embodiment of the present invention.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. However, the form described below is an example, and can be appropriately modified within a range obvious to those skilled in the art.

  FIG. 1 is a diagram for explaining a portion where an intraoral tissue treatment apparatus according to the first, second, and third aspects of the present invention is installed, and is a schematic diagram showing a state in the oral cavity. .

  As shown in FIG. 1, the intraoral tissue treatment apparatus 1 according to the first aspect, the oral tissue treatment apparatus 1a according to the second aspect, and the oral tissue treatment apparatus 1a according to the third aspect are all. , The whole (or part) is installed in the oral cavity. The intraoral tissue treatment apparatus according to each aspect includes the piezoelectric element 2. The piezoelectric element 2 is installed in the oral cavity and generates electric power (that is, generates electric power) using the occlusal force acting on the occlusal surface. By using the electric power generated in this way, or the magnetic force or ultrasonic wave generated due to the electric power, the tissue in the oral cavity can be treated or healing can be promoted. As will be described later, the occlusal force is not limited to the occlusal force acting on the occlusal surface.

  The piezoelectric element 2 is an example of a power generation element. When a pressure is applied from the outside, the piezoelectric element 2 is an element that deforms according to the magnitude of the pressure and generates an electromotive force according to the degree of the deformation. In each aspect, a piezoelectric bimorph element is used as the piezoelectric element 2. Thereby, even a relatively small device (piezoelectric element) can generate a large amount of power. For example, this piezoelectric bimorph element generates a current of 0.2 to 0.6 μA and a voltage of 10 to 22 V when the strain at the center is 0.2 to 0.6 mm. That is, the piezoelectric bimorph element is superior in power generation efficiency for its size compared to other piezoelectric elements. Further, the piezoelectric bimorph element can generate a magnetic force of, for example, 0.5 to 0.6 gauss around it by generating electric power. The piezoelectric element 2 is not limited to the piezoelectric bimorph element, and may be another piezoelectric element or a combination of a plurality of piezoelectric elements. Examples of other piezoelectric elements include a piezoelectric unimorph element. Further, the current value, voltage value, and magnetic force of the electric power generated by the piezoelectric element 2 are not limited to the above-described numerical values, and are appropriately selected according to the purpose and the like.

  Hereinafter, each aspect of the present invention will be described in detail. First, the intraoral tissue treatment apparatus 1 according to the first aspect will be described.

  As shown in FIG. 1, the intraoral tissue treatment apparatus 1 according to the first aspect is installed so as to be in contact with, for example, the upper end portion (oral end portion) of the implant. The intraoral tissue treatment apparatus 1 has a prosthesis 7 in addition to the piezoelectric element 2. At least a part of the prosthesis 7 is made of a curable material. Examples of the curable material include metals, resins (resins), and composite resins. When the prosthesis 7 is a metal, it is filled by bringing the metal into a molten state. As such a metal, iron, cobalt, nickel, Fe—Co alloy, Fe—Ni alloy, Fe—Co—Ni alloy, Pt—Co alloy, Mn—Bi alloy, or bismuth can be used.

  In the first aspect, the intraoral tissue treatment apparatus 1 is installed as follows. First, the piezoelectric element 2 is arrange | positioned so that the upper end part of an implant may be contacted. Subsequently, the prosthesis 7 is installed so as to cover the piezoelectric element 2. Next, the prosthesis 7 is shaped so as to have the same shape as the external shape of the teeth. Thereby, the prosthesis 7 is arranged on the occlusal surface. Thereby, installation of the intraoral tissue treatment apparatus 1 is completed. Although the prosthesis 7 is arranged on the occlusal surface, the prosthesis 7 may be installed at any site as long as the prosthesis 7 is installed at a site where the occlusal force is applied directly or indirectly. Here, the part where the occlusal force is applied directly or indirectly includes at least one of the occlusal surface, the buccal side surface, the labial surface, the palate surface, the lingual side surface, the mesial surface, and the distal surface. That is, the prosthesis 7 is installed so as to include at least a part of any one of the occlusal surface, the cheek side surface, the labial surface, the palate surface, the lingual surface, the mesial surface, and the distal surface. .

  In the first aspect, at least a part (for example, 6 kgf (about 59 N)) of the occlusal force (for example, 60 kgf (about 588 N)) acting on the occlusal surface is applied via the prosthesis 7 with piezoelectricity. As a result, the piezoelectric element 2 generates electricity. The electric power generated by the piezoelectric element 2 acts on the living tissue in the vicinity through the implant or directly. When the prosthesis 7 is conductive, it is preferable to provide a shield or an insulator between the piezoelectric element 2 and the prosthesis 7 so that the electric power from the piezoelectric element 2 can be supplied to the prosthesis 7 As a result, the electric power from the piezoelectric element 2 can be efficiently applied to the living tissue. The magnitude of the occlusal force varies depending on the site where it acts.

  As described above, in this aspect, electrical stimulation can be induced in the oral cavity using the occlusal force. The electrical stimulation thus induced remains as it is in the nearby nervous system, muscles, bones, teeth, blood and other living tissues (especially bone tissue or periodontal tissue (periodontal ligament tissue, gingival tissue, nerves). , Including blood vessels and other tissues)). In addition, the electrical stimulation generates a magnetic force in the oral cavity, and the magnetic force acts on a nearby living tissue as a magnetic stimulation. Furthermore, it is known that the piezoelectric element including the piezoelectric element 2 generates ultrasonic waves. Therefore, the ultrasonic waves generated in this way also act on nearby living tissue. Moreover, it is preferable to adjust the direction of the generated magnetic field according to the direction of the living tissue to be cured by adjusting the arrangement of the piezoelectric elements 2. In particular, the supply of electrical stimulation, magnetic stimulation, or ultrasonic stimulation as described above is preferably performed on a site where a surgical procedure such as a fracture site or bone fracture has been performed.

  The nearby living tissue is activated by at least one of electrical stimulation, magnetic stimulation, and ultrasound stimulation, and can improve its health condition. By this activation, in this aspect, in particular, the growth, repair, and reconstruction of bone tissue and periodontal tissue in the vicinity of the oral cavity can be promoted, or the healing of the disease can be promoted. That is, according to this aspect, it is possible to provide an intracavitary tissue treatment apparatus that is useful for treating tissues in the oral cavity using an occlusal force. It can also encourage patients and users to bite. Therefore, for example, it can be used to prevent dementia. Furthermore, in this embodiment, the stimulation of the mucous membrane in the oral cavity not only provides effects such as nerve activation, prevention of dementia and prevention of denture removal, but also encourages the act of biting. As a result, effects such as prevention of dementia, activation of bone tissue and the like of the tooth defect part, and promotion of regeneration of the lost alveolar bone can be obtained.

  In particular, when the intraoral tissue treatment device 1 according to the present embodiment is used in the field of oral surgery, it is possible to shorten the time required for repair after surgery for damaging bone tissue such as fractures and fractures, and immediately after implant implantation. It is possible to shorten the time required for repair of surrounding tissue, mainly bone tissue. Moreover, the repair can be performed satisfactorily. Usually, when the occlusal force is applied to the implant immediately after the implant is struck until the start of healing, the affinity between the implant and bone tissue is disturbed. For this reason, conventionally, in order to place the prosthesis on the upper end of the implant, a predetermined elapsed time has been provided. On the other hand, in the intraoral tissue treatment apparatus 1 according to this embodiment, it is not necessary to provide an elapsed period or even if it is provided, the elapsed time may be short. It can also ease the physical and mental burden of the patient. Further, in this case, the electric power from the piezoelectric element 2 or the magnetic force resulting from the electric power is transmitted to the lower end portion of the implant through the implant. Thereby, the living tissue in the vicinity of the lower end portion of the implant can be activated efficiently.

  In particular, when the intraoral tissue treatment apparatus 1 according to the present embodiment is used in a storage region, activation / regeneration of absorbed bone tissue and surrounding tissues of a periodontal disease patient, activation of a pulp in endodontic therapy, etc. Can be achieved.

  In addition, a stimulus that has acted on a living tissue in the vicinity of the oral cavity is transmitted to an adjacent living tissue, or a living tissue activated by the stimulus circulates in the body. For this reason, the intraoral tissue treatment apparatus 1 which concerns on this aspect can also promote or promote the health of the whole biological body. In other words, the intraoral tissue treatment apparatus 1 functions alone as a health promotion device that promotes the health of the living body. Furthermore, you may comprise so that another health promotion apparatus (for example, massage device) and the intraoral tissue treatment apparatus 1 which concerns on this aspect may be made to interlock | cooperate. For example, by adjusting the current value of the massage device in accordance with the current value generated in the oral tissue treatment apparatus 1, electrical stimulation can be given to a wide range of living tissues. Thereby, a synergistic effect can be acquired.

  In the first embodiment, the intraoral tissue treatment apparatus 1 may include a mantle 4 as shown in FIG. The jacket means 4 is a means for covering the piezoelectric element 2 and is covered with a prosthesis 7. Further, in the example shown in FIG. 1, the mantle 4 is in contact with the piezoelectric element 2. Therefore, the occlusal force applied to the mantle 4 via the prosthesis 7 is directly transmitted to the piezoelectric element 2. Thereby, the conversion efficiency at the time of converting an occlusal force into an electromotive force can be maintained high.

  Here, the mantle means 4 may be made of the same material as that which can be used for the prosthesis 7, or may be made of the shielding material or the insulator. Preferably, the mantle 4 is made of a material that does not hinder the deformation of the piezoelectric element 2 (for example, a resin material).

  In the case where the jacket means 4 is not composed of the shield or the insulator, the jacket means 4 preferably contains a ferromagnetic material. In this case, the jacket means 4 may be composed only of a ferromagnetic material, or may be configured by mixing a ferromagnetic material with the above-described curable material. Examples of the ferromagnetic material include iron, cobalt, and nickel. Of these, iron is preferable because it can be easily obtained, and cobalt is preferable because it is excellent in workability. Another example of a ferromagnetic material is an alloy. Examples of the alloy include Fe—Co alloy, Fe—Ni alloy, Fe—Co—Ni alloy, Pt—Co alloy, and Mn—Bi alloy. As described above, since the mantle 4 includes the ferromagnetic material, the magnetic force generated due to the electric power generated in the piezoelectric element 2 can be effectively applied to the tissue in the oral cavity via the mantle 4 or It will work efficiently. On the other hand, the jacket 4 may include a diamagnetic material instead of the ferromagnetic material. In this case, bismuth can be cited as a diamagnetic material. As described above, by including the diamagnetic material in the mantle 4, it is possible to promote cell proliferation of the tooth tissue itself provided with the mantle 4.

  As described above, by covering the piezoelectric element 2 with the jacket 4, it is possible to prevent the piezoelectric element 2 from being exposed in the oral cavity during installation or the like. Thereby, it can prevent getting wet with the water and the liquid in the oral cavity, or can be prevented from being decomposed by the liquid in the oral cavity. For this reason, it is possible to prevent a situation in which the piezoelectric characteristics are deteriorated or the piezoelectric element 2 does not function at all due to the wetting of the piezoelectric element 2 with liquid or the like in the oral cavity.

  In addition, by installing the mantle 4, it is possible to eliminate the occurrence of problems such as electric leakage due to the piezoelectric element 2 being wet with liquid or the like in the oral cavity. Therefore, even if the intraoral tissue treatment apparatus 1 according to this embodiment is installed in the oral cavity, the safety is high.

  In the above aspect, the generated electric power and the magnetic force due to the generated electric power are directly applied to an osteosynthesis plate or an osteosynthesis screw provided at the time of fracture or separation of a jaw bone, a skull, or a nasal bone, or a living tissue. You may comprise so that it may supply via. In this case, it is preferable to use a coil. As a result, tissue repair can be promoted.

  Then, the modification (1st modification-3rd modification) of a 1st aspect is demonstrated.

  In the first aspect described above, the example in which the intraoral tissue treatment device 1 is installed so as to be in contact with the upper end portion of the implant has been described, but the present invention is not limited to this. In the first modification, the intraoral tissue treatment apparatus 1 is installed in a dental caries cavity. In this case, the piezoelectric element 2 is installed so as to be embedded in the dental caries cavity. Also in this case, the intraoral tissue treatment apparatus 1 may include a mantle means 4. Subsequently, the prosthesis 7 is installed so as to cover the piezoelectric element 2. Thereby, installation of the intraoral tissue treatment apparatus 1 is completed. In this example, the prosthesis 7 also serves as a crown material (for example, an inlay or a crown). Then, the piezoelectric element 2 is installed in a restoration such as an inlay or a crown, and the piezoelectric element 2 is installed so as to come into contact with the metal core, the cut tooth or its tooth surface, or the pulp.

  In the second modification, the intraoral tissue treatment apparatus 1 further includes power storage means (not shown). The power storage means may be a battery or a capacitor. The power storage means is connected to the piezoelectric element 2. Thereby, not only can the electric power of the power storage means be supplied to the piezoelectric element 2, but also the electric power generated by the piezoelectric element 2 can be stored. As a result, electrical stimulation can be stably supplied to living tissue in the vicinity of the oral cavity regardless of the presence or absence of occlusal force.

  The power storage means is preferably integrated with the piezoelectric element 2. Thereby, it becomes easy to install the piezoelectric element 2 and the power storage means, and the wiring between them can be completely omitted or shortened. Alternatively, the power storage means is separate from the piezoelectric element 2. In this case, the power storage means is preferably connected to the piezoelectric element 2 by wiring. In this case, the power storage means may be installed on a tooth different from the tooth on which the piezoelectric element 2 is installed. In addition, it is not necessarily provided in the oral cavity, and may be provided, for example, in the nasal cavity or outside the body. When the power storage means is provided outside the body, the power storage means is preferably constituted by a solar cell.

  In the third modification, the intraoral tissue treatment apparatus 1 is further configured to include a stimulus output means (not shown). The stimulus output means is means for performing current stimulation, magnetic stimulation, or ultrasonic stimulation. Specifically, the stimulus output means is for transmitting the electric power generated by the piezoelectric element 2 in the oral cavity or outside the oral cavity, and is electrically connected to the piezoelectric element 2 (or the power generation element 3). Yes. In addition, since the piezoelectric element 2 generates magnetism or an ultrasonic wave when electric power is applied, the piezoelectric element 2 itself may function as a stimulus output unit or a part of the stimulus output unit.

  The stimulation output means includes, for example, a conductive suture. Therefore, installation of the intraoral tissue treatment apparatus 1 can be performed as part of the treatment. Specifically, when performing surgery on the surface of the oral mucosa including teeth, gums, buccal mucosa, and wounds on the surface of the teeth, the wound is sutured with a conductive suture, and The intraoral tissue treatment apparatus 1 can be installed by connecting the suture thread as the stimulation output means to the piezoelectric element 2. Note that the suture thread for suturing the wound and the suture thread (conductive filamentous body) connected to the stimulation output means may be separate, and in this case, both suture threads are connected. Examples of the conductive suture include a metal suture or a suture using a conductive resin. Further, the target site is not limited to a wound, and may be a treatment site such as when a nerve near the root of a tooth is removed or paralyzed. In this case, it is possible to prevent the treatment site from being corrupted by the electric power generated by the piezoelectric element 2 or the like.

  And in this aspect, if electric power generate | occur | produces in the piezoelectric element 2 in the intraoral tissue treatment apparatus 1, the electric power will be transmitted to a suture. Ultimately, electrical stimulation can be transmitted to a target site such as a wound that is sutured by a suture. By doing in this way, repair and regeneration of a target part can be promoted.

  In the above-described embodiment, the piezoelectric element 2 and the conductive suture may be connected regardless of the wound suture. In this case, the suture functions as a wiring.

  Moreover, you may combine a 2nd modification and a 3rd modification. That is, the intraoral tissue treatment apparatus 1 may include a power storage unit similar to the power storage unit according to the second modification.

  Furthermore, in the third modified example described above, the stimulation output means of the intraoral tissue treatment apparatus 1 may further include a conductive resin pad installed at the target site. Examples of the conductive resin pad include a clasp, a denture base, a portion covering a mucous membrane as a target site, or a pad having a predetermined shape. When the conductive resin pad is a denture floor, the electricity generated in the piezoelectric element 2 can be transmitted to the denture floor. Thereby, the mucous membrane in the vicinity of the denture floor can be stimulated. When the conductive resin pad is a clasp, the color of the clasp matches the color of the tooth, so that not only the aesthetics are high, but also the repair and regeneration of the target part can be promoted.

  Or in the 3rd modification mentioned above, the stimulus output means of the intraoral tissue treatment apparatus 1 is a means for performing magnetic stimulation. In this case, the stimulus output means is installed in the vicinity of the target site for promoting repair and regeneration. And since a stimulus output means is a means for performing a magnetic stimulus, a strong magnetic field can be formed, As a result, repair and reproduction | regeneration can be further accelerated | stimulated. An example of means for magnetic stimulation is a coil. And the range which can be magnetically stimulated can be easily adjusted by adjusting or changing the coil to be used. In this case as well, the stimulation output means of the intraoral tissue treatment apparatus 1 may further include a conductive resin pad installed at the target site.

  Next, the intraoral tissue treatment apparatus 1a according to the second aspect will be described. FIG. 2 is a view for explaining an intraoral tissue treatment apparatus 1a according to the second embodiment of the present invention, and is a partially enlarged view of FIG.

  The intraoral tissue treatment apparatus 1a shown in FIG. 2 is installed so as to be integrated with the denture. In the example shown in FIG. 2, the prosthesis 7 and the denture are connected so as to be integrated. Moreover, this intraoral tissue treatment apparatus 1a includes a stimulus output means, as in the third modification of the first aspect described above. However, in the second mode, the stimulus output means functions as a magnetic attachment 6 for preventing the denture from falling off by exerting a magnetic force as a result of the occlusal force acting on the piezoelectric element 2. Specifically, the magnetic attachment 6 functions as an electromagnet, and is installed between a metal coping or Cornus krone installed at the upper end (oral side end) of the tooth root and the piezoelectric element 2. As a result, while the occlusal force is acting on the piezoelectric element 2, the magnetic force acts between the magnetic attachment 6 and the coping or cornus skurone, and the denture can be prevented from falling off. In addition, as shown in FIG. 2, coping and a cornus skurone are installed in the upper end part (oral cavity side edge part) of the tooth | gear which only the root remained (namely, tooth root). In addition, in the example shown in FIG. 2, although it was set as coping or a corne krone, it may replace with these and the restoration material installed in a root face upper end part may be sufficient.

  And in the 2nd aspect, when the piezoelectric element 2 generates electric power by occlusal force, the magnetic attachment 6 functions as an electromagnet, and it can prevent that a denture falls off. In particular, when the occlusal force is expressed, the magnetic attachment 6 has an increased function as an electromagnet (and consequently a drop-off preventing function). Therefore, it is possible to suppress a decrease in the magnetic force of the magnetic attachment 6 by periodically generating power. Therefore, the user actively performs the act of biting with the motive of periodically generating power. That is, the intraoral tissue treatment apparatus 1a according to the present embodiment can not only prompt the patient or user to act of biting, but can also help prevent dementia of the patient or user by the act of biting. It becomes. Further, in the oral cavity, it is difficult to apply a force in the lateral direction (the direction in which teeth are arranged) to the magnetic attachment 6. For this reason, the magnetic attachment 6 is difficult to be removed during use. On the other hand, when it is not used (when it is not engaged), no magnetic force acts, so the vertical direction (perpendicular to the tooth arrangement direction). It can be easily removed by applying a certain amount of force in the direction toward the inside of the oral cavity. Therefore, according to the second aspect, it is possible to provide an intraoral tissue treatment apparatus that is easy for a user or dentist to remove.

  In the second aspect, the intraoral tissue treatment apparatus 1a may be installed so as to be integrated with the removable bridge instead of the denture, or installed so as to be integrated with other restorations. May be. In these cases, the same effect can be achieved. In addition, the intraoral tissue treatment device 1a may be installed at the upper end of a metal (for example, titanium) implant, and in this case, it can be prevented from falling off the implant.

  Also in the second aspect, it is possible to apply at least one of the first to third modifications of the first aspect described above to the intraoral tissue treatment apparatus 1a.

  In particular, according to the second aspect, the intraoral tissue treatment device 1a can be used as a correction retention device. In this case, the magnetic attachment of the orthodontic retention device is attached to a miniscrew implant or a prosthesis. Also in this case, the repair and regeneration of bone tissue, periodontal tissue, particularly periodontal ligament tissue can be promoted, and the reversion caused thereby can be suppressed. Moreover, the intraoral tissue treatment apparatus 1a according to the second aspect can be incorporated into a floor correction apparatus for dynamic correction treatment (so-called tooth movement treatment). In this case, the intraoral tissue treatment apparatus 1a can promote activation of bone metabolism by the generated electric power, or the magnetic force or ultrasonic wave resulting from the electric power. For this reason, the intraoral tissue treatment apparatus 1a can complete the correction treatment earlier than before, and can safely perform the correction treatment. In addition, as a modification of the second aspect, an oral tissue treatment apparatus may be configured by incorporating the piezoelectric element 2 into a bracket of a normal multi-bracket apparatus (a multi-bracket apparatus of the type cured with a bracket and a wire). Good. When the magnetic implant or the magnetic attachment is not used for maintaining the retaining device, the electric power from the piezoelectric element 2 and the magnetic force resulting from it are supplied from the floor portion in contact with the oral mucosa through the oral mucosa. . In addition, the intraoral tissue treatment device may be used as a correction device or a part thereof.

  Next, a 3rd aspect is demonstrated.

  In the third aspect, the intraoral tissue treatment apparatus 1b is composed of the piezoelectric element 2 as shown in FIG. Preferably, the piezoelectric element 2 is covered by the jacket means 4.

  In the third aspect, the piezoelectric element 2 has a long shape. And one end of the piezoelectric element 2 is installed in the site | part (for example, between two adjacent teeth) where the occlusal force which acted on the occlusal surface acts in the oral cavity. Thereby, the electric power generated by the piezoelectric element 2 can be taken out from the other end. As described above, in the third aspect, by adjusting the shape of the piezoelectric element 2, it is possible to freely set the site where the electric power, the magnetic force or the ultrasonic wave resulting from the electric power should be used, in the oral cavity. As will be described later, the occlusal force is not limited to the occlusal force acting on the occlusal surface.

  In the third aspect, the piezoelectric element 2 is installed between the teeth. However, the installation location of the piezoelectric element 2 is not limited to between the teeth, and the occlusal force such as the occlusal surface is directly applied. Alternatively, the piezoelectric element 2 may be installed such that one end of the piezoelectric element 2 is embedded in the dental caries cavity and the other end is exposed to the oral cavity. Furthermore, you may install the other end of the piezoelectric element 2 between other teeth.

  In the first to third aspects described above, the occlusal force has been described by taking the occlusal force acting on the occlusal surface as an example, but it is not limited to these examples. That is, the occlusal force only needs to be expressed by the masticatory muscles. Therefore, the piezoelectric element 2 may be disposed anywhere within the oral cavity. Examples of the site to which the occlusal force is applied directly or indirectly include an occlusal surface, a cheek lateral surface, a labial surface, a palatal surface, a lingual surface, a mesial surface, and a distal surface.

  In the first to third aspects described above, the piezoelectric element 2 has been described by taking the bimorph type as an example, but is not limited to the bimorph type. That is, the piezoelectric element 2 may be a unimorph type or a laminated type. If it is a unimorph type, the power generation efficiency is inferior to that of the bimorph type, but the oral tissue treatment apparatus can be downsized. If it is a laminated type, it is possible to generate an amount of electric power corresponding to the occlusal force applied in the thickness direction or the occlusal force applied in the direction perpendicular to the thickness direction. Therefore, an element to be used as the piezoelectric element 2 is appropriately selected according to efficiency, size, and the like.

  Subsequently, a fourth aspect of the present invention will be described.

  In the intraoral tissue treatment apparatus according to the fourth aspect, the piezoelectric element 2 is disposed at a site where the occlusal force acts. An example of the site where the occlusal force works is the surface of teeth (opposite teeth) that bite each other. In this embodiment, the piezoelectric element 2 is fixed to one or both of the upper jaw mouthpiece and the lower jaw mouthpiece. In order to fix the piezoelectric element 2 to the mouthpiece, the piezoelectric element 2 is placed close to the tooth biting space in the mouthpiece tooth receiving space, or to the tooth receiving space if the mouthpiece is resinous. Install in the resin. Instead of this, the piezoelectric element 2 may be fixed to a mouthpiece in which the upper mouthpiece and the lower jaw mouthpiece are connected to each other to be integrated.

  And in a 4th aspect, activation of bone metabolism can be promoted by a user biting. In particular, according to the fourth aspect, maintenance and promotion of alveolar bone health and prevention of pathological bone resorption can be performed.

  Moreover, you may use the intraoral tissue treatment apparatus which concerns on a 4th aspect as a toe positioner (tooth positioner) which is a retention device for correction, an invisible retainer (invisible retainer), or a part thereof. As a result, it is expected to prevent reversal by increasing the metabolism of the alveolar bone. Since the invisible retainer is transparent, it is preferable in that the arrangement of the piezoelectric element 2 can be easily confirmed from the outside, but it is not necessarily transparent (invisible).

  Next, the fifth aspect of the present invention will be described.

  The intraoral tissue treatment apparatus according to the fifth aspect is installed in a person who has a higher frequency of clenching teeth than usual, such as an athlete. As a specific example, the piezoelectric element 2 is incorporated in a sports mouthpiece worn by an athlete.

  According to the fifth aspect, when the user clenches, power generation occurs, and the electric power acts to make the teeth and alveolar bone healthy. In particular, athletes often impair the health of teeth and alveolar bone due to clenching, but according to this aspect, they can prevent the health of teeth and alveolar bone from being impaired, or It can promote healing after the health of teeth and alveolar bone is impaired.

  Moreover, in the intraoral tissue treatment apparatus according to this aspect, it is preferable that the electric power generated by the piezoelectric element 2 flows as a current to bone tissue such as gums, soft tissue (gingiva or buccal mucosa) in the oral cavity, or periodontal tissue. . As a result, current stimulation can be given to the user. As a result, it is expected that users (especially athletes) who are stimulated by electric current will exhibit higher performance than usual.

  Next, the sixth aspect of the present invention will be described.

  The intraoral tissue treatment apparatus according to the sixth aspect is installed in a patient who has a toothpaste. As a specific example, the piezoelectric element 2 of the intraoral tissue treatment apparatus is installed on a resin bite plate. In this case, the piezoelectric element 2 is installed in a resin inside a space (for example, a groove) formed in the bite plate or between grooves (first groove and second groove) on the upper and lower surfaces of the bite plate.

  In the sixth aspect, the piezoelectric element 2 generates power through the bite plate when the user brushes his teeth. By using this power, it can be expected that electricity, magnetism, and ultrasonic waves will be emitted to the teeth, which will help maintain bone health.

  In the sixth aspect, the electric power obtained by the piezoelectric element 2 by the user's toothbrushing is made to flow to the bone tissue, the soft tissue in the oral cavity (gingiva or buccal mucosa), or the periodontal tissue as a current. May be. As a result, the patient himself / herself becomes aware that he / she is bruising. That is, the intraoral tissue treatment device also functions as a toothpaste sensor. Here, it is known that tooth decay has a problem for the health of teeth and bones. An example of a problem is that teeth are worn by toothpaste, which impairs dental health. Therefore, by causing the intraoral tissue treatment device to function as a toothpaste sensor, it is possible to prompt the user to stop the toothpaste, and as a result, dental health can be maintained. In addition, the health of the teeth can be maintained by using the electric power obtained by the piezoelectric element 2 by toothbrushing.

  Next, the seventh aspect of the present invention will be described.

  The intraoral tissue treatment apparatus according to the seventh aspect is configured such that the piezoelectric element 2 generates power by sound or vibration. Therefore, in this embodiment, the piezoelectric element 2 is exposed in the oral cavity. Therefore, in order to prevent the piezoelectric element 2 from getting wet, it is preferable that the outer cover 4 is covered. The sound may be generated by vibration of the throat, may be generated by vibration of the nasal cavity tissue, may be generated by the internal organs, or when the mouth is open It may be sound or vibration that enters from the outside. Examples of throat vibrations include vibrations when talking and vibrations when singing. As described above, the piezoelectric element 2 generates electric power by sound or vibration, and maintenance of bone health or the like is promoted by using the electric power or the magnetic force or ultrasonic wave generated due to the electric power.

  Next, an eighth aspect of the present invention will be described.

  The intraoral tissue treatment apparatus according to the eighth aspect is configured such that the piezoelectric element 2 generates electricity using snoring. It is preferable to configure the oral tissue treatment apparatus so that the electric power obtained by the piezoelectric element 2 by snoring flows to the bone tissue, the soft tissue (gingiva or buccal mucosa) in the oral cavity, or the periodontal tissue. Thereby, the intraoral tissue treatment apparatus also functions as a snoring sensor. When the intraoral tissue treatment device functions as a snoring sensor, the user is aware of snoring and tries to avoid snoring. As a result, the elimination of snoring is expected. And if snoring is resolved, it is expected not only to realize a good sleep, but also to prevent sleep apnea syndrome.

  In addition, all the intraoral tissue treatment apparatuses which concern on the 5th-8th aspect mentioned above function also as a health promotion apparatus. Further, in the fifth, sixth, and eighth embodiments described above, the electric power obtained by the piezoelectric element 2 is used as a current, and the soft tissue (gingiva or buccal mucosa) in the oral cavity, or the bone tissue or tooth in the vicinity of the oral cavity. As a means for flowing to the surrounding tissue, one configured in substantially the same manner as the “stimulus output means” described in the third modification of the first aspect described above can be used.

  In the first to eighth aspects described above, the intraoral tissue treatment apparatus includes the piezoelectric element 2, but instead of the piezoelectric element 2, a thermoelectric conversion element that generates electric power in accordance with a temperature difference in the oral cavity is included. But you can. An example of the heat transfer element is a Peltier element. And this thermoelectric conversion element also functions as a power generation element like the piezoelectric element 2, and the electric power generated by them, or the magnetic force or the ultrasonic wave generated due to the electric power is used for treatment in the oral cavity. The Alternatively, in the first to eighth aspects described above, the piezoelectric element 2 and the heat transfer conversion element may be used in combination. By using it together, the power generation efficiency can be increased.

  A first embodiment of the present invention will be described. In Example 1, as shown in FIG. 3, the piezoelectric element 2 of the intraoral tissue treatment apparatus 1 was attached to the dentition model, and the voltage value and current value of the electric power generated by the occlusal force were measured. Specifically, a piezoelectric bimorph element was used as the piezoelectric element 2. In addition, the piezoelectric element 2 is fixed at the left canine and premolar part of the lower jaw dentition model with only the left molar part removed, and the corresponding part of the piezoelectric element 2 is directly bitten by the left first molar of the upper jaw It was. And the voltage and electric current which were generated from the output part set behind the piezoelectric element 2 corresponding part when biting were measured. The results are shown in Table 1.

  As can be seen from Table 1, according to Example 1, when the strain at the central portion of the piezoelectric element 2 is 0.2 to 0.6 mm, the current is 0.2 to 0.6 μA and the current is 10 to 22 V. It was found that voltage was generated. Here, it is known that the alternating current electricity used in the alternating current electrical stimulation method (Semi-invasive method) has a current of 0 to 50 μAp (fixed to an optimal current of 30 μAp for bone augmentation) and a voltage of 1.25 Vp. It has been. The AC electrical stimulation method is a treatment method in which a local current is secondarily generated in the Helmholtz coil through an AC current, and the generated AC current is used for stimulation. Therefore, according to Example 1, it turned out that the electric power equivalent to an alternating current electrical stimulation method can be obtained by occlusal force.

  Next, a second embodiment of the present invention will be described. In Example 2, the magnetic field was measured when a force was applied to the piezoelectric element 2 of the intraoral tissue treatment apparatus 1. The same piezoelectric element 2 was used in Example 1 and Example 2. For the measurement of the magnetic field, a fatigue tester (see FIG. 4) prepared for measuring the magnetic field and ultrasonic waves was used. The results are shown in Table 2.

  As can be seen from Table 2, according to Example 2, it was found that 0.5 to 0.6 Gauss magnetism was generated. Here, in the AC electromagnetic stimulation method, a) 1 to 100 V = 1.0 to 1.5 mV / cm in bone is used, or b) 0.1 to 20 gauss (for example, 2 gauss) magnetism is 8 per day. It is known to expose the affected area for ~ 14 hours, or c) to expose the affected area to 800 gauss magnets 30 times a day, 3 times a day. Experimentally, it is also known that bone formation is actively performed at 0.4 to 2.0 Gauss. Therefore, according to Example 2, it turned out that the magnetic force comparable to the alternating current electrical stimulation method and the magnetic force that bone formation is performed actively are obtained by the occlusal force.

  As described above, from Examples 1 and 2, using the intraoral tissue treatment apparatus according to each aspect described above, it is necessary for the growth, repair, and reconstruction of bone and surrounding tissues by electrical stimulation or magnetic field stimulation in the oral cavity. It has been demonstrated that a large amount of power can be supplied with the patient's own or user's own occlusal force.

  Therefore, it can be seen that the oral tissue treatment apparatus of the present invention is useful for shortening the repair and regeneration of tissues by electrical stimulation and the like as well as for maintaining the health of patients by encouraging the patient or user to bite. It was. It is clear that current, voltage and magnetism are generated when force is applied to the piezoelectric element 2 as in the above data.

  The present invention can be suitably used in the field of the health appliance industry.
