以下、本発明を実施するための形態について図を参照しながら説明する。 Hereinafter, it will be described with reference to the drawings embodiments for practicing the invention. 本発明の歯科矯正装置は、図1~図6に見られるように、ベース1、上顎側外周壁2、下顎側外周壁3、上顎側内周壁4及び舌位置矯正フランジ5が、弾性又は可撓性を備えたシリコーン樹脂で一体成形される。 Orthodontic appliance of the present invention, as seen in FIGS. 1-6, the base 1, the upper jaw side peripheral wall 2, the lower jaw side peripheral wall 3, the upper jaw side inner wall 4 and the tongue position corrective flange 5, elastic or soluble and it is integrally molded with a silicone resin having wrinkles properties. 本例の歯科矯正装置は、各部を構成するシリコーン樹脂の変形によって位置ズレを吸収することにより、型取りを要することなく、多数の患者がそのまま利用できる(汎用性)。 Orthodontic device according to this embodiment, by absorbing the positional displacement by the deformation of the silicone resin constituting the respective sections, without requiring the mold removal, can be directly utilized a large number of patients (versatility). また、本例の歯科矯正装置は、上顎6及び下顎7の歯列61,71でベース1をしっかりと噛ませること(後掲図8参照)により、口腔の装着を安定させることができる。 Furthermore, orthodontic appliance of the present example, by firmly bite the base 1 with teeth 61 and 71 of the upper jaw 6 and the lower jaw 7 (refer 掲図 8), which can stabilize the mounting of the mouth.

このほか、可撓性又は弾性を備えたシリコーン樹脂で一体成形することにより、本例の歯科矯正装置を口腔に装着した場合、歯茎や頬9に対する圧迫が少なく、患者に痛みを与えず、また歯茎や頬9を傷つける虞もない。 In addition, by integrally molded with a silicone resin with a flexible or elastic, if the orthodontic device of the present example was attached to the oral cavity, less pressure on the gums and cheek 9, without giving pain to the patient and there is no fear of damaging the gums and cheeks 9. また、可撓性又は弾性を備えたシリコーン樹脂で一体成形された歯科矯正装置は、例えば上顎側内周壁4の外周面に形成した3条の上支持条41の倣い面411の角度を調整する場合(図7及び図8参照)、シリコーン樹脂が容易に削れるので、前記角度の調整が容易である利点がある。 Moreover, flexible or orthodontic devices that are integrally molded with a silicone resin with an elastic adjusts the angle of the scanning surface 411 of the support strip 41 on the Article 3 which is formed for example on the outer peripheral surface of the upper jaw side inner wall 4 If (see FIGS. 7 and 8), since the silicone resin is easily scraped, there is the advantage adjustment of the angle it is easy.

ベース1は、上顎6及び下顎7の歯列61,71に挟まれる平面視U字状の部分である。 Base 1 is a plan view U-shaped part between the teeth 61 and 71 of the upper jaw 6 and the lower jaw 7. シリコーン樹脂製である本例のベース1は、数mm厚である。 Base 1 in this example is made of silicone resin is several mm thick. 本例では、便宜上、前歯部611,711に挟まれる部分をベース前部11、臼歯部612,712に挟まれる部分をベース側部12と呼ぶ。 In this example, for convenience, it will be referred to the part that is sandwiched between the portion which is sandwiched between the anterior 611,711 base front 11, the molars 612,712 based side 12. 本例のベース1は、ベース前部11とベース側部12との厚みが等しくなっている。 Base 1 of the present example, the thickness of the base front 11 and the base side portion 12 are equal. しかし、例えば両者の厚みに差を設け、ベース側部12を臼歯部612,712に噛ませた状態で、前歯部611,711をベース前部11から離して、不正咬合の開咬を矯正させる働きを付加してもよい。 However, for example, providing a difference in both the thickness and in a state in which the bite the base side 12 to the posterior teeth 612,712, to release the anterior portion 611,711 from the base front 11, is added serve to correct the open bite malocclusion that may be.

ベース側部12は、上顎側の上面と下顎側の下面とが内外方向の幅が同じ大きさで、また前記上面及び下面それぞれの外周縁及び内周縁が内外方向にズレなく、一致している。 Base side 12, in the upper surface and the width is the same size of the lower surface and the inside and outside direction of the lower jaw side of the upper jaw side, also the outer peripheral edge and an inner peripheral edge of each of the upper and lower surfaces there is no shift in and out direction, match . 具体的には、上顎側外周壁2の内周面と下顎側外周壁3の内周面とがベース側部12を挟んで連続し、また上顎側内周壁4の外周面と舌位置矯正フランジ5の外周面とがベース側部12を挟んで連続しており、ベース側部12の上面と下面とが上下対称である(図4参照)。 Specifically, the inner peripheral surface and the inner peripheral surface of the lower jaw side peripheral wall 3 of the upper jaw side peripheral wall 2 is continuously across the base side portion 12 and the outer circumferential surface and the tongue position corrective flange upper side inner wall 4 and 5 the outer peripheral surface of the can is continuous across the base side portion 12, the upper and lower surfaces of the base side portion 12 is vertically symmetrical (see Figure 4). このため、上顎6の臼歯部612は、上顎側内周壁4の外周面が内側から当接し、また下顎7の臼歯部712は、ベース側部12の内周縁から下方に延びる舌位置矯正フランジ5の基部が内側から当接する。 For this reason, the molar region 612 of the upper jaw 6, the outer peripheral surface of the upper jaw side in the peripheral wall 4 is in contact from the inside, also molar region 712 of the lower jaw 7, tongue position corrective flange 5 extending from the inner peripheral edge of the base side 12 on the lower side the base of the abuts from the inside.

ベース前部11は、上顎側の上面が広く、下顎側の下面が狭い上下非対称である(図7及び図8参照)。 Base front 11, top surface of the upper side is wide, the lower surface of the lower jaw side is narrower vertically asymmetrical (see FIGS. 7 and 8). ベース前部11の上面は、上顎側外周壁2の内周面を上顎側内周壁4の外周面から遠ざけるため、広くなっている。 Upper surface of the base front 11, in order to distance the inner circumferential surface of the upper side peripheral wall 2 from the outer peripheral surface of the upper jaw side inner wall 4 is wider. これに対し、ベース前部11の下面は、下唇72に内側から当接させる下顎側外周壁3を下顎7の前歯部51にも外側から当接させるため、前記下顎側外周壁3を下方に突出させるベース前部11の外周縁が内方向にズレており、また舌位置矯正フランジ5の基部を前歯部51に内側から当接させるため、前記ベース前部11の内周縁が外方に寄せているので、内外方向の幅が狭くなっている。 In contrast, the lower surface of the base front 11, in order to abut the lower jaw side peripheral wall 3 which abut from the inside on the lower lip 72 from the outside to the anterior portion 51 of the lower jaw 7, the lower the lower jaw side peripheral wall 3 the outer peripheral edge of the base front 11 that is protruded to have displaced inwardly, also in order to abut the base of the tongue position corrective flange 5 from the inside to the anterior portion 51, an inner peripheral edge of the base front 11 outwardly We are asked, mediolateral width is narrower. この結果、ベース前部11は、上顎側の上面が広く、下顎側の下面が狭い上下非対称になっている。 As a result, the base front 11, the top surface of the upper jaw side is wide, lower surface of the lower jaw side is to narrow vertically asymmetric.

上顎側外周壁2は、ベース1の外周縁から上方に突出し、上唇62に内側から当接する外方に向けて凸な断面円弧状の壁面部分である。 Maxillary outer peripheral wall 2 is a convex arc-shaped cross section of the wall portion towards from the outer edge of the base 1 to the outside abutting protruding upward, the upper lip 62 from the inside. シリコーン樹脂製である本例の上顎側外周壁2は、数mm厚である。 Silicone resin a is this example maxillary outer peripheral wall 2 is the number mm thickness. 本例の上顎側外周壁2は、上顎6側の口腔前庭に収まる大きさ及び外形で、頬9を内側から圧迫しないように頬筋と平行に内側に傾いており、上縁の左右中央に上唇小帯回避凹部21を、上縁の左右対称位置に一対の頬小帯回避凹部22,22をそれぞれ設けている。 Maxillary outer peripheral wall 2 of the present example, the size and outer shape which fits in the upper jaw 6 side of the buccal cavity, parallel to the Ho-suji not to compress the cheeks 9 from the inside is inclined inward in the lateral center of the upper edge the upper lip frenulum avoid recess 21, are provided each with a pair of cheek frenulum avoid recesses 22 and 22 on the left and right symmetrical position of the upper edge. 上顎側外周壁2の端部は、左右の臼歯部611に及ぶところまで延びている(図8参照)ので、上唇62を介した口輪筋上部の圧力が上顎6の歯列61に加わる虞がない。 End of the upper jaw side peripheral wall 2, so extends until it covers the left and right posterior teeth 611 (see FIG. 8), a possibility that the pressure of the orbicularis muscle top through the upper lip 62 is applied to the teeth 61 of the upper jaw 6 It is not.

下顎側外周壁3は、ベース1の外周縁から下方に突出して下唇72に内側から当接し、かつ下顎6の前歯部611に外側から当接する外方に向けて凸な断面円弧状の壁面部分である。 The lower jaw outer peripheral wall 3, abuts from the inside to the lower lip 72 from the outer peripheral edge of the base 1 so as to protrude downwards, and convex circular arc-shaped cross section of the wall toward the outside which abuts from the outside to the front teeth section 611 of the lower jaw 6 Partial is. シリコーン樹脂製である本例の下顎側外周壁3は、下顎7の前歯部711に当接する付近を除いて数mm厚である。 Lower jaw outer peripheral wall of this example is made of a silicone resin 3, it is the number mm thickness, except for the vicinity in contact with the anterior portion 711 of the lower jaw 7. 本例の下顎側外周壁3は、既述したように、下唇72に内側から当接させ、下顎7の前歯部51にも外側から当接させる必要から、ベース前部11に対して内外方向に肉厚の断面山形で、ベース側部12に向かって薄くしている(図4と図7又は図8を比較対照)。 Lower jaw side peripheral wall 3 of the present embodiment, as described above, and out is allowed to abut from inside the lower lip 72, the need to contact from outside the anterior portion 51 of the lower jaw 7, the base front 11 the thickness of the cross-section in Yamagata direction, and is thinned toward the base side portion 12 (compare and contrast the Figure 4 and Figure 7 or Figure 8). これは、下顎7の前方に弾性変形しにくい肉厚のシリコーン樹脂を宛てがっているのと同じ状態である。 This is the same state as that Atega~tsu a forward elastic deformation hardly thickness of the silicone resin of the lower jaw 7. こうして、下顎側外周壁3は、特に下顎7が前方に突出しようとする発育を抑制又は防止している。 Thus, the lower jaw side peripheral wall 3, in particular inhibit or prevent the growth of the mandible 7 is to project forward.

本例の下顎側外周壁3は、下縁の左右中央に下唇小帯回避凹部32を設けている(図3参照)。 Lower jaw outer peripheral wall 3 of the present example is provided with a lower lip frenulum avoid recess 32 in left and right center of the lower edge (see Figure 3). また、本例の下顎側外周壁3は、ベース1に沿って延び、下顎7の前歯部71に外側から当接する下支持条31を内周面に設けている(図7及び図8参照)。 Also, the lower jaw side peripheral wall 3 of the present example, extends along the base 1 is provided with a lower support strip 31 which abuts from the outer to the inner circumferential surface to the anterior portion 71 of the lower jaw 7 (see FIGS. 7 and 8) . 下支持条31は、断面頂部を前記下顎7の前歯部71に部分的に当接させ、下顎7の前歯部71の成長を許容しつつ、全体的に等しく当接するように前記前歯部71の並びを矯正する。 Under the support strip 31, a cross apex partially brought into contact with the anterior portion 71 of the lower jaw 7, while allowing the growth of the anterior portion 71 of the lower jaw 7, wherein the anterior portion 71 to abut equally Overall We want to correct the sequence. 下顎7の前歯部71に対する下支持条31の当たり具合は、前記下支持条31を部分的に削って調整する。 Per condition of lower support strip 31 with respect to the anterior portion 71 of the lower jaw 7 is adjusted by cutting the bottom supporting strip 31 partially. 本例の下支持条31は、下顎側外周壁3と一体にシリコーン樹脂で形成されているので、削りやすい。 Lower support strip 31 of the present embodiment, since it is formed with a silicone resin integrally with the lower jaw side peripheral wall 3, is easily machined.

上顎側内周壁4は、ベース1の内周縁から上顎6の前歯部61に当接する高さだけ上方に突出し、前記前歯部61に内側から当接する外方に向けて凸な断面円弧状の壁面部分である。 Maxillary side inner wall 4 projects upwardly only inner height abuts on the anterior portion 61 of the upper jaw 6 from the periphery of the base 1, wherein the anterior portion 61 and outwardly abutting the inner convex arcuate cross section of the wall Partial is. シリコーン樹脂製である本例の上顎側内周壁4は、数mm厚である。 This case maxillary side inner circumferential wall 4 of which is made of silicone resin is several mm thick. 本例の上顎側内周壁4は、上顎6の前歯部61に内側から当接し、前記前歯部61を外に向けて押し、上顎の発育を助ける。 Upper jaw side in the peripheral wall 4 of the present example, the anterior portion 61 of the upper jaw 6 abuts from the inside, push the front teeth 61 toward the outside, help the growth of the upper jaw. また、上顎6の前歯部61に内側から当接する上顎側内周壁4は、舌位置矯正フランジ5の働きにより持ち上げられた舌8の舌尖81が前記前歯部61を内側から押すことを防止し、上顎6の前歯61の並びが悪くなる事態を回避する。 Also, the upper jaw side inner wall 4 in contact with the inner side to the anterior portion 61 of the upper jaw 6 is to prevent the tongue tip 81 of the tongue 8 which is lifted by the action of the tongue position corrective flange 5 pushes the front tooth 61 from the inside, sequence of front teeth 61 of the upper jaw 6 avoid the worse situation.

本例の上顎側内周壁4は、外周面が上顎6の前歯部61に直接当接するのではなく、外方に向かって下り勾配の外周面に等間隔で、それぞれベース1に沿って設けられる3条の上支持条41の断面頂部それぞれを上顎6の前歯部61に内側から当接させている(図7及び図8参照)。 Maxillary side inner circumferential wall 4 of the present example, instead of the outer peripheral surface abuts directly on the anterior portion 61 of the upper jaw 6, at equal intervals outwardly on the outer circumferential surface of the downward slope, respectively provided along the base 1 It has a cross-section top portion of the support strip 41, respectively on the article 3 by abutting the inside anterior portion 61 of the upper jaw 6 (see FIGS. 7 and 8). 上支持条41は、上顎6の前歯部61の成長を許容しつつ、全体的に等しく当接するように前記前歯部61の並びを矯正する。 Above support Article 41, while allowing the growth of the anterior portion 61 of the upper jaw 6, to correct the alignment of the anterior portion 61 so as to be in contact as a whole equally. 上顎6の前歯部61に対する上支持条41の当たり具合は、前記上支持条41を部分的に削って調整する。 Per condition the upper support strip 41 against the anterior portion 61 of the upper jaw 6 is adjusted by cutting the strip on the support 41 partially. 本例の上支持条41は、上顎側内周壁4と一体にシリコーン樹脂で形成されているので、削りやすい。 On the supporting strip 41 of the present embodiment, since the integral with the upper jaw side inner wall 4 is formed with a silicone resin, and easy shaving.

本例の上支持条41は3条あり、しかもいずれも外方に向かって下り勾配の外周面に等間隔で設けられているので、全上支持条41の断面頂部を含む倣い面411は方に向かって下り勾配である。 On the supporting strip 41 of the present example is Article 3, moreover since both are arranged at equal intervals toward the outside on the outer circumferential surface of a downward slope, the copying surface 411 that includes a cross-section top portion of the entire upper support strip 41 is rectangular It is a descending slope towards the. これから、各上支持条41を個別又は部分的に削ってそれぞれの断面頂部の高さを加減すれば、倣い面411の勾配角度を変えることができ、前記倣い面411に等しく当接するように矯正される上顎6の前歯部61の矯正具合を細かく調整できる。 From this, if adjusting the height of each cross top by cutting the respective upper support strip 41 to separate or partially, it is possible to change the slope angle of the scanning surface 411, corrected to equal abut on the copying surface 411 You can fine-tune the correction degree of the anterior portion 61 of the upper jaw 6 to be.
本例の上支持条41は、上顎側内周壁4と一体にシリコーン樹脂で形成されているので、削りやすい。 On the supporting strip 41 of the present embodiment, since the integral with the upper jaw side inner wall 4 is formed with a silicone resin, and easy shaving.

舌位置矯正フランジ5は、ベース1の内周縁から下方に延び、徐変に水平に曲がる断面湾曲状フランジ部分で、舌8下方に潜り込み、舌尖81を下顎7の前歯部711から離して、前記前歯部711が前記舌尖81に押されて下顎7が押し出される状態を解消する。 Tongue position corrective flange 5 extends from the inner peripheral edge of the base 1 down, in cross-section curved flange part to bend gradual change horizontally, tongue 8 dive down, and then release the tongue tip 81 from the anterior portion 711 of the lower jaw 7, the Anterior 711 to eliminate a state in which the lower jaw 7 is pushed is pushed to the tongue tip 81. 本例の舌位置矯正フランジ5は、平坦部分の左右中央に前後方向に延びる舌小帯回避切欠51を設けた平面視U字状であるが、前記舌小帯回避切欠51により左右に分割された舌位置矯正フランジ5を一対設ける構成でもよい。 Tongue position corrective flange 5 of the present example is a plan view U-shaped having a lingual frenulum avoiding notch 51 extending longitudinally in the lateral center of the flat portion, is divided into right and left by the lingual frenulum avoiding notch 51 the tongue position corrective flange 5 may be a pair providing configuration was. また、舌位置矯正フランジ5は、舌8を下顎7にくっつけさせない働きを有すればよく、本例より薄くても又は厚くてもよいし、例えば複数枚の薄板を積層して構成し、前記積層数を調整可能にしてもよい。 Moreover, the tongue position corrective flange 5 may if you have a function that is not to stuck to the tongue 8 to the lower jaw 7, also or even may be thicker thinner than this example, it is constituted for example by laminating a plurality of thin plates, the it may be adjustable number of layers.

本例の舌位置矯正フランジ5は、ベース側部12の内周縁から下方に延びる舌位置矯正フランジ5の基部を下顎7の歯列71に内方から当接させることにより、歯列矯正の働きも発揮する。 Tongue position corrective flange 5 of the present example, by making the inside of the base of the tongue position corrective flange 5 extending from the inner circumferential edge of the base side portion 12 in the downward teeth 71 of the lower jaw 7 abuts, acts orthodontic It also exhibited. これから、上顎6の歯列61と下顎7の歯列71とが揃うように、本例の本例の舌位置矯正フランジ5は、上顎側内周壁4の外周面と舌位置矯正フランジ5の基部の外面とを内外方向に一致させている。 Now, to align the teeth 71 of the teeth 61 and the lower jaw 7 of the upper jaw 6, tongue position corrective flange 5 of the present example of the present example, of the outer peripheral surface and the tongue position correction flange 5 of the upper jaw side in the peripheral wall 4 base It is a an outer surface to match the inside and outside direction. また、本例の舌位置矯正フランジ5は、上顎側内周壁4と厚みが等しいので、上顎側内周壁4の内周面と舌位置矯正フランジ5の基部の内面とが連続し、舌を包み込む空間を形成している。 In addition, the tongue position corrective flange 5 of the present example, since the equal upper jaw side in the peripheral wall 4 and the thickness, and the inner surface of the base of the inner circumferential surface of the upper jaw side in the peripheral wall 4 tongue position corrective flange 5 is continuous, wraps around the tongue It has to form a space. これにより、前記空間が口腔での舌8を拘束し、不正咬合の矯正に悪影響が出る舌8の動きを封じている。 As a result, the space constrain the tongue 8 at the mouth, I have sealed the movement of the tongue 8, which adversely affect the correction of malocclusion.

本発明の歯科矯正装置は、患者が起きている間に、図8に見られるように、上顎6及び下顎7の歯列61,71でベース1を噛むように口腔に装着させ、上唇62及び下唇72がくっつくように口を閉じる状態を規定時間(例えば1時間)維持させて、反対咬合を解消又は軽減させる。 Orthodontic appliance of the present invention, while the patient is awake, as seen in Figure 8, is attached to the oral cavity so as to bite the base 1 with teeth 61 and 71 of the upper jaw 6 and the lower jaw 7, the upper lip 62 and It defines the state to close the mouth as the lower lip 72 is stick time (eg 1 hour) is allowed to maintain, and to eliminate or reduce the opposite bite. 歯科矯正装置を口腔に装着して口を閉じると、上唇62が口輪筋上部に引っ張られるが、上顎側外周壁2が上唇62と上顎6の前歯部611との間に介在し、上顎側外周壁2の内周面と前記前歯部611との間に隙間Δを形成して(図7~図9参照)、前歯部611に対する上唇62の圧迫を防ぐ。 When you close the mouth with the orthodontic appliances attached to the oral cavity, but upper lip 62 is pulled in the orbicularis oris top, upper jaw outer peripheral wall 2 is interposed between the front teeth section 611 of the upper lip 62 and the upper jaw 6, upper jaw side by forming a gap Δ between the inner peripheral surface of the outer wall 2 and said anterior portion 611 (see FIGS. 7 to 9), to prevent compression of the upper lip 62 to the anterior portion 611. 上顎側外周壁2は、口輪筋上部に対応して口腔前庭に収まる外形及び大きさとしているが、頬筋と平行に内側に傾くことで頬9への圧迫をなくし、口を閉じた口腔に歯科矯正装置を装着し続けることの負担を軽減している。 Maxillary outer peripheral wall 2, although the outer shape and size fit to the buccal cavity, corresponding to orbicularis oris top eliminates the pressure on the cheek 9 by tilting inward in parallel with the cheek muscles, and mouth closed mouth thereby reducing the burden of having to continue wearing the orthodontic device.

歯科矯正装置を口腔に装着して口を閉じると、図7に見られるように、下唇72と下顎7の前歯部711との間に、内外方向に肉厚な下顎側外周壁3が介在することになり、前記下唇72に負荷を与えて口輪筋下部の発育を促すと同時に、下顎7の突出を妨げて、前記下顎7の発育を抑制又は防止する。 When you close the mouth with the orthodontic appliances attached to the oral cavity, as seen in FIG. 7, between the front teeth portion 711 of the lower lip 72 and the lower jaw 7, a thick lower jaw inside and outside direction outer peripheral wall 3 intervention it means that, at the same time promote the growth of orbicularis oris bottom by applying a load to the lower lip 72, and preventing the protrusion of the lower jaw 7, to suppress or prevent the growth of the lower jaw 7. 本例の下顎側外周壁3は、下顎7の前歯部711に対して下支持条31を当接させているが、下顎7の臼歯部712との間には隙間Δを形成している(図7~図9参照)。 Lower jaw side peripheral wall 3 of the present example, although abut the bottom supporting strip 31 against the anterior portion 711 of the lower jaw 7, to form a gap Δ between the posterior portion 712 of the lower jaw 7 ( see Fig. 7 to 9). 下顎7の発育を抑制又は防止する働きは、口を閉じなくても、歯科矯正装置を口腔に装着すれば得られるが、口を閉じることにより、口輪筋下部の発育を促す働きが得られる。 Serve to inhibit or prevent the growth of the lower jaw 7, even without closing the mouth, but the orthodontic equipment be obtained by attaching to the oral cavity, by closing the mouth, it works to encourage the growth of mouth ring muscle bottom obtained . これから、本発明の歯科矯正装置は、患者が意識的に口を閉じることのできる間、例えば起きている間での使用が好ましい。 From this, the orthodontic device of the present invention, while it is capable of closing the patient consciously mouth, preferably for use in while awake, for example.

上顎側内周壁4は、上顎6の前歯部611に内側から押し、前記上顎6の発育を助ける働きのほか、直接当接又は上支持条41が当接する前歯部611を整列させる歯列矯正の働きを有する。 Upper jaw side in the peripheral wall 4, push from the inside to the front teeth section 611 of the upper jaw 6, of working to help the growth of the upper jaw 6 addition, orthodontic direct contact or upper support Article 41 to align the contact with anterior 611 It has a function. こうした上顎側内周壁2の歯列矯正の働きは、上顎6の発育を助ける働きに対して二次的なものであり、上顎6の発育を助ける働きを十分に発揮させる観点から、歯科矯正装置を口腔に装着したら、上顎6及び下顎7を動かさないことが好ましい。 Action of orthodontic these maxillary side inner wall 2 are merely secondary to serve to assist the growth of the upper jaw 6, from the viewpoint of sufficiently exhibiting the function of helping the growth of the upper jaw 6, orthodontic devices Once you have attached to the oral cavity, it is preferable not to move the upper jaw 6 and lower jaw 7. 同様に、舌位置矯正フランジ5の基部も歯列矯正の働きを有するが、あくまで舌8を持ち上げる働きが主であり、舌8がむやみに動かないことが好ましいことから、やはり歯科矯正装置を口腔に装着したら、上顎6及び下顎7を動かさないことが好ましい。 Similarly, although the base of the tongue position corrective flange 5 also has a function of orthodontic, only it works to lift the tongue 8 is the main, since it is preferred that the tongue 8 does not work blindly, still the orthodontic appliance oral Once mounted, it is preferred to not move the upper jaw 6 and the lower jaw 7.
