`{Detailed Description of the Invention]
`{Field of the Invention]
`{0001]
`The present invention relates to a brace.
`{Background of the Invention]
`{0002]
`Conventionally, there is a thing using the wire as a brace and there are some which cured the alignment of teeth
`and tabling by giving certain force (static load) to a row of teeth by the return power of a wire. That is, when
`certain force is given to a row of teeth, it is based on the principle that orthodontics is possible because the

`alveolar bone which supports the gear tooth in the gum deforms gradually.
`{0003]
`However, in the orthodontics using a wire. for the child who is especially the marriageable age of orthodontics. a
`period is pain and does not last long in many cases from what is started very long (it being early six months,
`usually several years).
`{0004]
`if the sample A which applied certain force to the row of teeth is compared with the sample B which applied
`vibration force to the row of teeth as shown in Eigjlfia) in order to shorten the period of such orthodontics.
`research that the direction of the sample B which applied vibration force has an effect in shortening of a period
`is made (nonpatent literature 1).
`{0005]
`If similarly the sample C which applied certain force to the row of teeth is compared with the sample D which
`applied certain force + vibration force to the row of teeth as shown in Fig.1? (b). research that the direction of
`the sample D which applied certain force + vibration force has an effect in shortening of a period is also made
`(nonpatent literature 2).

`with the nonpatent literature 2, if sufficient [for 2 minutes ] at once, it is two weeks. That is, **
`What is necessary will be for what is necessary to bejust to continue the therapy only for 1.5 hours on the 1st,
`and just to continue the therapy only for 2 minutes at once with the nonpatent literature 2 by a Patent
`document 1, at two weeks.
`{0007]
`He can understand that shortening it is [the period of orthodontics ] larger to give vibration force rather than
`giving certain force with a wire etc. to a row of teeth from these researches has an effect.
`{0008]
`And the equipment (Patent document 1) which gives supersonic vibration to the circumference organization of
`the mounting part of the mouthpiece to which movement of the gear tooth for reformation is urged as what tried
`utilization of these researches, and the equipment (Patent document 2) which gives supersonic vibration to the
`gear tooth for reformation are proposed.

`
`The exploded perspective view which looked at the mouthpiece 7 of structure which Eggpiled up on the inside-
`and-outside duplex from the side front, and Fig.4 are the exploded perspective views which looked at the
`
`mouthpiece 7 of Mfrom the back side.
`{0029]
`The mouthpiece 7 comprises the inside mouthpiece 7A directly put on the row of teeth 3, and the outside
`mouthpiece 7B put on the outside of the inside mouthpiece 7A, if Fig.5 (a) is referred to.
`{0030]
`As a material of the inside mouthpiece 7A and the outside mouthpiece 7B, The material in which it was ordinarily
`used as a mouthpiece (or mouth guard) material, and the safety of the sanitary aspect was guaranteed, For
`example, if what molded the EVA (ethylene—vinyl acetate resin) sheet which is a polymer material is used (the
`manufacturing method of the mouthpiece 7 is mentioned later), since the influence of a gear tooth, the allergy to
`gum, etc. can be suppressed, it is preferable.
`{0031]
`as for an EVA sheet, electrical insulation is secured although not restricted to an EVA sheet as a material --
`thermal insulation —- also carrying out -- it is preferable in order to function. When an EVA sheet is used
`especially for the inside mouthpiece 7A, can give softness to the inside mouthpiece 7A and by this, Since
`moderating actions work to the high-speed component of the mechanical oscillation which it is transmitted from
`the electric motor 8 mentioned later to a gear teeth [for reformation / 3g and 3h 3 portion, it becomes possible
`to prevent beforehand damage to a gear teeth [for reformation / 3g and 3h ] portion.
`{0032]
`Into a gear teeth l: by the side of the surface of the outside mouthpiece 7B / for reformation / 3g and 3h ]
`portion, The outward swelling section 7a of a little larger inner shape like Fig.5 (b) than the outline shape of the
`electric motor 8 which is an actuator is formed, and the electric motor 8 small to the gap in this swelling section
`7a and lightweight is stored sideways (it becomes abbreviated rectangular directions to the row of teeth 3 like i a
`vibrating direction ]). With the eccentricity weight attached to the axis of rotation, this electric motor 8 is a
`structure which generates mechanical oscillation, and is used widely as vibrator functions, such as a cellular
`phone.
`{0033]
`And where the inside mouthpiece 7A is put inside [which stored the electric motor 8 in the swelling section 7a ]
`the outside mouthpiece 78, By ultrasonic welding etc., itjoins airtightly and the outer surface of the inside
`mouthpiece 7A and the inner surface of the outside mouthpiece 78 come to be unified so that neither saliva nor
`wash water may enter in the swelling section 7a from a superposition surface. Here, actually, the airtightness
`shouldiust be more than the level with which a watertight is maintained, as moisture does not penetrate.
`{0034]
`Like Fig.2 and Fig.5 (0), when the electric motor 8 is a direct-current (DC) motor,The electric supply line 9 is
`airtightly pulled out outside from the through hole [refer to [ of frig-JS (b) / the 7f ]] formed in the swelling
`section 7a of the outside mouthpiece 7B, is further pulled out by disclosure from between lips, and is connected
`to the cell (battery) 11 via the variable resistor volume 10 and the switch 12. The variable resistor volume 10 and
`the cell ii are installed on the desk near the user putting on the mouthpiece 7, etc. By adjusting the DC voltage
`level supplied to the electric motor 8 by the variable resistor volume 10, the rotational speed of the electric
`motor 8, i.e., vibration frequency, can be adjusted. Oscillation frequency (vibration frequency) has several Hz -
`about 100 Hz of preferable numbers. The electric motor 8 can also be used as an exchange (AC) motor.
`{0035]
`
`Next, the manufacturing method of the mouthpiece 7 is described. As shown in Fig-f: 2, a user's row-of-teeth
`plaster-model E is completed at Step 82 by molding at Step 81 by making the impression material adhere to a
`user‘s row of teeth 3, removing from the row of teeth 3, slushing gypsum fibrosum into the impression material
`holding row—of—teeth form, and taking out gypsum fibrosum, after solidifying.
`{0036]
`if correcting implements, such as the bracket 4 and the wire 5, are attached to a user's row of teeth 3, here,
`When equipping the row of teeth 3 with the inside mouthpiece 7A of the mouthpiece 7 and the inside mouthpiece
`7A is caught in the edge of a correcting implement, there is a possibility that the inside mouthpiece 7A may be
`damaged or the bracket 4 may separate from the dental surface. in order to prevent such fault, the gap between
`the portion of the bracket 4 of row-of-teeth plaster-model E or the portion of the wire 5 can be filled up with a
`waxing compound etc., and edge can be lost. According to this method, when manufacturing the inside
`mouthpiece 7A, before making the impression material adhere to the row of teeth 3, after filling up the gap
`between the bracket 4 or the wire 5 with the nonpoisonous waxing compound etc. which can be poured with

`
`water and losing edge, a user’s burden reduces compared with the case where impression extraction is
`performed.
`{0037]
`the EVA sheet heated and softened -- row-of—teeth plaster-model E -- reliance -- after carrying out suction
`molding and cooling. the inside mouthpiece 7A is completed at Step S3 by removing row-of—teeth plaster-model
`A from an EVA sheet. This step S3 is the same as the manufacturing method of the conventional mouthpiece.
`{0038]
`If manufacture of the inside mouthpiece 7A in which thickness (thick) differs is possible and the thick thin inside
`mouthpiece 7A is used by changing the thickness of an EVA sheet. while a wearing feeling will become good. the
`transfer characteristic of the mechanical oscillation from the electric motor 8 comes to improve. the gear tooth
`3 -- it is also possible by changing the thickness of the inside mouthpiece 7A every a—Sn to change the transfer
`characteristic of the mechanical oscillation to each gear teeth 3a-3n.
`{0039]
`And where the inside mouthpiece 7A is inserted in row-of-teeth plaster-model E in Step 83, Gypsum fibrosum is
`slushed into the silicon type which performed new templating and was completed by step S4 using silicon resin
`etc, and after solidifying, inside mouthpiece plaster-model F is completed at Step 35 by taking out gypsum
`fibrosum.
`
`{0040]
`At Step 86, plaster—model F’ used as the swelling section 7a of the outside mouthpiece 7B is adhered to inside
`mouthpiece plaster-model F, the EVA sheet heated and softened —— inside mouthpiece plaster-model F --
`reliance -- after carrying out suction molding and cooling, the outside mouthpiece 7B is completed at Step S7 by
`removing inside mouthpiece plaster-model F from an EVA sheet.
`{0041]
`Then, where the inside mouthpiece 7A is put at Step SS inside [which stored the electric motor 8 in the swelling
`section 7a ] the outside mouthpiece 7B, The mouthpiece 7 is completed by joining airtightly the outer surface of
`the inside mouthpiece 7A, and the inner surface of the outside mouthpiece 78 with ultrasonic welding, adhesives,
`etc.. and unifying. As for the total thickness of the mouthpiece 7, about 1-6 mm is preferable.
`{0042]
`Here the junction to the outer surface of the inside mouthpiece 7A. and the inner surface of the outside
`mouthpiece 78, Although junction of only the peripheral edge part of the swelling section 7a which stored the
`electric motor 8 of the outside mouthpiece 78 may be sufficient. it is preferable to join airtightly the whole
`periphery edge of the inside mouthpiece 7A and the outside mouthpiece 7B, in order to prevent the periphery
`edge of the inside mouthpiece 7A and the outside mouthpiece 78 from having been got turned up, and it is
`preferable also in order to wash and save after use of the mouthpiece 7.
`{0043]
`According to the mouthpiece 7 of this embodiment. since the electric motor 8 which generates mechanical
`oscillation (mechanical stimulus) is stored in a gear teeth [ of the superposition part of the mouthpieces 7A and
`7B of an inside—and-outside duplex / for reformation / 3g and 3h ] portion, vibration can be correctly given only
`to a gear teeth {for reformation / 3g and 3h ] portion.
`{0044]
`Since the electric motor 8 is stored in the mouthpiece 7, even if it does not go to a dental clinic. a therapy can
`be continued simply and safely at home at any time, for example.
`{0045]
`Since the mechanical oscillation of the electric motor 8 is transmited to a gear teeth [for reformation / 3g and
`3h ] portion via the inside mouthpiece 7A, it can soften the pain of the gear tooth resulting from direct
`transmission of the mechanical oscillation being carried out to the portion which are the gear teeth 3g and 3h for
`reformation.
`
`{0046]
`If the electric motor 8 is stored in the mouthpiece 7 by a sealed state. it will be sanitary and washing in cold
`water will also become possible further again.
`{0047]
`If the electric motor 8 is used as an actuator, it is inexpensive, and since what that is used widely as vibrator
`functions, such as a cellular phone, small and lightweight can be diverted if it is the structure which generates
`mechanical oscillation with the eccentricity weight attached to the axis of rotation of the electric motor 8, it is
`more inexpensive.
`{0048]
`If the electric motor 8 is stored in the mouthpiece 7 so that a vibrating direction may turn into abbreviated

`
`rectangular directions to the row of teeth 3, in being the structure which generates mechanical oscillation with
`eccentricity weight, Since a hand of cut and a vibrating direction correspond, even if the electric motor 8 is a
`type long to a shaft direction, the projection height from the mouthpiece 7 becomes low. and sense of
`incongruity decreases. Since vibration of the electric motor 8 can be soon given to the gear teeth 3g and 3h for
`reformation, vibration transmission efficiency becomes good.
`{0049]
`If the electric motor 8 is driven with a direct-current (DC) power supply, the vibration frequency (rotational
`speed) of the electric motor 8 can be easily adjusted by regulation of the DC voltage level by the variable
`resistor volume 10. If DC power supply are used as the cell 11, a therapy becomes possible also at places (for
`example, outdoors etc.) which do not have an AC receptacle.
`{0050]
`If the row of teeth 3 is equipped, it can make the electric motor 8 which is an actuator be placed correctly for
`generating mechanical oscillation into a gear teeth [for reformation / 3g and 3h ] portion. since the mouthpiece
`7 is form with which the whole row of teeth 3 is equipped.
`{0051]
`When direct contact of the electric motor 8 is carried out to the inner surface of the swelling section 7a, etc.,
`since vibration force is easy to be controlled, it is preferable to store in the gap in the swelling section 7a what
`was previously stored in the state where vibration force is not controlled in covering created by metal or resin
`(for example, ABS plastics).
`{0052]
`For example, as shown in $4ng (a) and (b), where it inserted in the periphery of the casing of the electric motor
`8 the covering 20 created by metal and resin of owner top cylindrical shape and the peripheral wall of the
`eccentricity weight 8a of the electric motor 8 is surrounded with this covering 20, What is necessary isjust to
`store the electric motor 8 in the gap in the swelling section 7a with the covering 20.
`{0053]
`
`As shown in frigid (a) and (b), while forming in the flexible printed circuit board 21 of rectangular form the pair of
`leads 21a and 21b for power supplies which extend in the length direction, Terminal (not shown) for electric
`supply which can contact the leads 21a and 21b, respectively is formed in the back surface of the electric motor
`8, and the type which enabled it to adjust a fitting location for the electric motor 8 along the leads 21a and 21b
`of the flexible printed circuit board 21 can be considered. In this type, after adjusting the fitting location of the
`electric motor 8. the electric motor 8 can be fixed to the flexible printed circuit board 21 with soldering the
`terminal for electric supply and the leads 21a and 21b of the electric motor 8. Terminal (not shown) for electric
`supply of the connector (for example, male connector) 22 of one side can be soldered to the leads 21a and 21b
`of the flexible printed circuit board 21.
`{0054]
`And where it inserted in the periphery of the casing of the electric motor 8 the covering 24 created by owner top
`semicircle tubed metal and resin and the peripheral wall of the eccentricity weight 8a of the electric motor 8 is
`surrounded with this covering 20, What is necessary is to lock the claw part 24a of the covering 24 to either of
`the locking holes 210 of the flexible printed circuit board 21, to fix it, andjust to store the electric motor 8 in the
`gap in the swelling section 7a with the covering 24.
`{0055]
`It can stand in a row in the swelling section 7a, the covering section 7e which covers the periphery of the
`connector 22 of one side airtightly can be formed, and the connector (for example, female connector) 23 of
`outside to the other side can be removably combined with the connector 22 in this covering section 7e from a
`right-angled direction. When combining the connector 23 of the other side with the connector 22 of one side, the
`periphery of the connector 23 of the other side also comes to be airtightly covered with the covering section 7e.
`The electric supply line 9 of the connector 23 of the other side is airtightly pulled out outside from the
`connector 23, and comes to be pulled out from between lips to disclosure.
`{0056]
`As shown in Figjiil (a) and (b), the electric supply line 9 of the electric motor 8 is airtightly pulled out outside
`from 7f of through holes formed in the swelling section 7a of the outside mouthpiece 7B, but as for the
`mouthpiece 7, it is preferable to form full water proof from washing whole with water.

`Then, as shown in Figlfi (a), the tube 25 which has the insert hole 25a of the electric supply line 9 is provided,
`and the flange 25b is formed at the tip of this tube 25, for example. The same EVA (ethylene-vinyl acetate resin)
`as the material of the mouthpiece 7 of the material of the tube 25 is the optimal. The length of the tube 25 has
`the preferable length sufficiently pulled out from between lips to disclosure.

`And the electric supply line 9 is made to insert in the insert hole 25a from the flange 25b side, and it is made to
`stick like FEMS (b) like the arrow a. pressing the flange 25b to the side surface of the swelling section 7a. In this
`state, cover the outer surface of the swelling section 7a, and the outer surface of the tube 25 with the thermal
`insulation 26A and 268, respectively, make it expose, and near the flange 25b by the dryer or a heat gun, Like
`the arrow b, if a hot wind is sprayed near the flange 25b, the flange 25b will come to be airtightly welded on the
`side surface of the swelling section 7a like Fig} 5 (c) because the flange 25b melts.

`Since the waterproofness of the drawer portion of the electric supply line 9 will improve as compared with the
`case where the electric supply line 9 is only pulled out outside, from 7f of through holes of the swelling section
`7a of the outside mouthpiece 78 if it does in this way, full water proof-ization can be attained.
`{0060]
`Since the electric supply line 9 will be covered with the tube 25 made from EVA and the electric supply lines 9,
`such as a product made from vinyl chloride, cannot touch the mouth, the safety of a sanitary aspect also comes
`to be guaranteed. Appearance also becomes good.

`As shown in Eigjffla) and (b), the electric supply line 9 of the connector 23 of the other side is airtightly pulled
`out outside from the connector 23, but as for the mouthpiece 7, it is preferable to form full water proof from
`washing whole with water.
`{0062]
`Then, for example, as shown in Figxifi (a), the tube 25 which has the insert hole 25a of the electric supply line 9
`is provided, the periphery of the connector 23 of the other side is covered at the tip of this tube 25, and the
`tubed part 25c projected further ahead is formed in it. The same EVA (ethylene-vinyl acetate resin) as the
`material of the mouthpiece 7 of the material of the tube 25 is the optimal. The length of the tube 25 has the
`preferable length sufficiently pulled out from between lips to disclosure.
`{0063]
`The covering section 7e which stands in a row in the swelling section 7a inserts the tubed part 250 of the tube
`25 in a periphery airtightly, and forms it in the shape of l in which doubling is possible ] a cartridge, The tubed
`part 25c of the tube 25 can be airtightly inserted in the covering section 7e, and the connector 23 of outside to
`the other side can be removably combined with the connector 22 of the covering section 7e from a right-angled
`direction with doubling.
`{0064]
`Since the waterproofness of the drawer portion of the electric supply line 9 will improve from the connector 23
`of the other side as compared with the case where the electric supply line 9 is only pulled out outside if it does
`in this way. full water proof-ization can be attained.
`{0065]
`Since the electric supply line 9 will be covered with the tube 25 made from EVA and the electric supply lines 9,
`such as a product made from vinyl chloride, cannot touch the mouth, the safety of a sanitary aspect also comes
`to be guaranteed. Appearance also becomes good.

`As shown in m the mouthpiece 7 may be form with which a part of row of teeth 3 (the example of Eiggjugear
`teeth 3f-3h for reformation) is equipped, in this case, the mouthpiece 7 becomes compact and the burden at the
`time of a user’s wearing comes to reduce it.
`{0067]
`Although the mouthpiece 7 also usually covers the alveolar part of mandible of the tooth form 1, in order to give
`mechanical oscillation only to the row of teeth 3, it may cut the portion equivalent to an alveolar part of
`mandible. The mouthpiece 7 becomes compact, while the mass of the mouthpiece 7 becoming small and
`becoming easier to spread vibration by such out.
`{0068]
`In order to equip the whole row of teeth 3 with the mouthpiece 7, constituted from the inside mouthpiece 7A
`directly put on the row of teeth 3, and the outside mouthpiece 7B put on the outside of the inside mouthpiece
`7A, but. As shown in Mb) and (b), it is also possible to join the square piece-shaped inside mouthpiece 7A
`airtightly, and to unify by making the inside mouthpiece 7A into square piece form, inside [ which stored the
