The curved portion 20 protrudes toward the lip side with respect to the rod-shaped main body 19. The bending portion 20 of this example is formed by bending a part of the rod-shaped main body 19. The bending portion 20 can apply a holding force for holding the position to the rod-shaped main body 19 by contacting the oral cavity, particularly a holding force related to the direction from the soft palate to the lips.

斯かる形状保持部材６は、Ｕ字形状のマウスピース１１の両端近傍の部位１６及び１８が互いに変位しないように当該部位１６及び１８を橋絡してこれら相互の位置を保持している。換言すれば、形状保持部材６は、マウスピース１１の歪みに抗する力を生じるようにマウスピース１１に固着されている。   Such a shape holding member 6 bridges the parts 16 and 18 in the vicinity of both ends of the U-shaped mouthpiece 11 and holds the positions of the parts 16 and 18 so as not to be displaced from each other. In other words, the shape holding member 6 is fixed to the mouthpiece 11 so as to generate a force against the distortion of the mouthpiece 11.

形状保持部材６は、本例では金属製であるが、例えば合成樹脂製、硬質プラスチック製であってもよく、マウスピース１１に対して硬質であってもよく、透光性を有していてもよく、また、形状保持部材６は、本例では棒状であるが、例えば帯状であってもよい。   The shape holding member 6 is made of metal in this example, but may be made of, for example, synthetic resin or hard plastic, may be hard with respect to the mouthpiece 11, and has translucency. In addition, the shape holding member 6 has a rod shape in this example, but may have a band shape, for example.

本例の歯列矯正具１は、形状保持部材６に代えて又は加えて、例えば図４から図６の夫々に示すように、歯列２に沿ってＵ字形状に伸びていると共に矯正具本体５の形状を保持すべくマウスピース１１の舌側の部位３１に固着された形状保持部材５１及び歯列２に沿ってＵ字形状に伸びていると共に矯正具本体５の形状を保持すべくマウスピース１１の頬側の部位３２に固着されている形状保持部材５２のうちの少なくとも一方を具備していてもよい。斯かる場合には、マウスピース１１には、形状保持部材５１又は５２が配されるように歯列２に沿って伸びた溝が形成されていてもよい。尚、図４から図６においては、歯列矯正具１を簡略に示している。   The orthodontic appliance 1 of the present example extends in a U shape along the dentition 2 as shown in FIGS. 4 to 6, for example, instead of or in addition to the shape retaining member 6, and the orthodontic appliance. In order to maintain the shape of the main body 5, the shape maintaining member 51 fixed to the tongue-side part 31 of the mouthpiece 11 and the U-shape along the dentition 2 are extended, and the shape of the correction tool main body 5 is maintained. At least one of the shape holding members 52 fixed to the cheek side portion 32 of the mouthpiece 11 may be provided. In such a case, the mouthpiece 11 may be formed with a groove extending along the tooth row 2 so that the shape holding member 51 or 52 is disposed. 4 to 6 show the orthodontic appliance 1 in a simplified manner.

図４に示す形状保持部材５１は、本例では、金属製の棒状又は帯状のワイヤ等からなる。形状保持部材５１は、マウスピース１１に沿ってＵ字形状に伸びていると共にマウスピース１１に沿う方向において所定の間隔をもってマウスピース１１の舌側の部位３１に固着されており、本例では、一端が一方の頬側の大臼歯１５に対応する形状を有したマウスピース１１の舌側の部位１６に固着されており、他端が他方の頬側の大臼歯１７に対応する形状を有したマウスピース１１の舌側の部位１８に固着されており、そして、マウスピース１１の伸びる方向において一端と他端との間に位置する中央部が前歯１４に対応する形状を有したマウスピース１１の舌側の部位２５に固着されている。形状保持部材５１はマウスピース１１に対して硬質である。形状保持部材５１は、マウスピース１１の歯肉を覆う部位に配されているが、例えばマウスピース１１の歯牙３を覆う部位に配されていてもよい。尚、形状保持部材５１は、マウスピース１１の歯牙３と歯肉との境界を覆う部位に沿うように湾曲して波形状に形成されていてもよい。また、形状保持部材５１は、本例では所定の間隔をもってマウスピース１１に固着されているが、例えばその全体がマウスピース１１に埋設等により固着されていてもよい。   In this example, the shape holding member 51 shown in FIG. 4 is made of a metal rod-like or strip-like wire. The shape holding member 51 extends in a U shape along the mouthpiece 11 and is fixed to the tongue-side portion 31 of the mouthpiece 11 with a predetermined interval in the direction along the mouthpiece 11. One end is fixed to the tongue-side portion 16 of the mouthpiece 11 having a shape corresponding to one buccal molar 15 and the other end has a shape corresponding to the other buccal molar 17. The mouthpiece 11 is fixed to the tongue side portion 18 of the mouthpiece 11, and the center portion located between one end and the other end in the extending direction of the mouthpiece 11 has a shape corresponding to the front tooth 14. It is fixed to the part 25 on the lingual side. The shape holding member 51 is hard with respect to the mouthpiece 11. The shape holding member 51 is disposed at a portion that covers the gums of the mouthpiece 11, but may be disposed at a portion that covers the teeth 3 of the mouthpiece 11, for example. In addition, the shape holding member 51 may be curved and formed in a wave shape along a part covering the boundary between the tooth 3 and the gingiva of the mouthpiece 11. Further, in this example, the shape holding member 51 is fixed to the mouthpiece 11 with a predetermined interval. However, the entire shape holding member 51 may be fixed to the mouthpiece 11 by being embedded or the like.

また、歯列矯正具１が形状保持部材６及び５１を具備している場合には、例えば図５に示すように、形状保持部材６の一端が形状保持部材５１の一端に一体的に連結されていると共に形状保持部材６の他端が形状保持部材５１の他端に一体的に連結されて、一つの形状保持部材が形成されていてもよい。   Further, when the orthodontic appliance 1 includes the shape holding members 6 and 51, one end of the shape holding member 6 is integrally connected to one end of the shape holding member 51, for example, as shown in FIG. 5. In addition, the other end of the shape holding member 6 may be integrally connected to the other end of the shape holding member 51 to form one shape holding member.

図６に示す形状保持部材５２は、本例では、金属製の棒状又は帯状のワイヤ等からなる。形状保持部材５２は、マウスピース１１に沿ってＵ字形状に伸びていると共にマウスピース１１に沿う方向において所定の間隔をもってマウスピース１１の頬側の部位３２に固着されており、本例では、一端が一方の頬側の大臼歯１５に対応する形状を有したマウスピース１１の頬側の部位２６に固着されており、他端が他方の頬側の大臼歯１７に対応する形状を有したマウスピース１１の頬側の部位２７に固着されており、そして、マウスピース１１の伸びる方向において一端と他端との間に位置する中央部が前歯１４に対応する形状を有したマウスピース１１の頬側（口唇側）の部位２８に固着されている。形状保持部材５２はマウスピース１１に対して硬質である。形状保持部材５２は、マウスピース１１の歯肉を覆う部位に配されているが、例えばマウスピース１１の歯牙３と歯肉との境界を覆う部位に沿うように湾曲して波形状に形成されていてもよい。また、形状保持部材５２は、本例では所定の間隔をもってマウスピース１１に固着されているが、例えばその全体がマウスピース１１に埋設等により固着されていてもよい。   In this example, the shape holding member 52 shown in FIG. 6 is made of a metal rod-like or strip-like wire. The shape holding member 52 extends in a U shape along the mouthpiece 11 and is fixed to the cheek side portion 32 of the mouthpiece 11 at a predetermined interval in the direction along the mouthpiece 11. One end is fixed to the buccal side portion 26 of the mouthpiece 11 having a shape corresponding to the one buccal side molar 15, and the other end has a shape corresponding to the other buccal side molar 17. The mouthpiece 11 is fixed to the cheek-side portion 27 of the mouthpiece 11, and the center portion located between one end and the other end in the extending direction of the mouthpiece 11 has a shape corresponding to the front tooth 14. It is fixed to the part 28 on the cheek side (lip side). The shape holding member 52 is hard with respect to the mouthpiece 11. The shape holding member 52 is arranged in a portion covering the gum of the mouthpiece 11, and is curved and formed in a wave shape, for example, along a portion covering the boundary between the tooth 3 and the gum of the mouthpiece 11. Also good. In addition, in this example, the shape holding member 52 is fixed to the mouthpiece 11 with a predetermined interval. However, the entire shape holding member 52 may be fixed to the mouthpiece 11 by embedding or the like.

以上の歯列矯正具１が上顎側の歯列２に装着された場合には、凹状内面１３の部位４が矯正すべき歯牙３に圧接することにより、当該歯牙３に対して予め定めた目的位置に向かう適切な圧力が与えられる。ところで、仮にマウスピース１１に歪みが生じると、部位４の矯正すべき歯牙３に対する当接角が変化してしまい、矯正すべき歯牙３に対する目的位置に向かう圧力が分散する結果、適切な圧力を矯正すべき歯牙３に与え得なくなる。しかしながら、本例の歯列矯正具１は、上述のようなマウスピース１１の歪みを形状保持部材６によって生じさせないように形成されているので、矯正すべき歯牙３に対して適切な圧力を与え続けることができ、而して、歯列矯正の効率化を図り得る。   When the orthodontic appliance 1 described above is mounted on the maxillary dentition 2, the portion 4 of the concave inner surface 13 is pressed against the tooth 3 to be corrected, whereby a predetermined purpose is set for the tooth 3. Appropriate pressure towards the position is provided. By the way, if the mouthpiece 11 is distorted, the contact angle of the part 4 with the tooth 3 to be corrected changes, and the pressure toward the target position with respect to the tooth 3 to be corrected is dispersed. It cannot be given to the tooth 3 to be corrected. However, since the orthodontic appliance 1 of this example is formed so as not to cause the distortion of the mouthpiece 11 as described above by the shape holding member 6, an appropriate pressure is applied to the tooth 3 to be corrected. Thus, it is possible to improve the efficiency of orthodontics.

本例の歯列矯正具１によれば、歯列２に着脱自在となるように当該歯列２に沿って伸びていると共に、矯正すべき歯牙３の形状に対応する形状を有した部位４が、当該歯牙３が矯正後に配されるべき目的位置に対応する位置に配されている矯正具本体５と、口腔に沿って伸びていると共に矯正具本体５の形状を保持すべく矯正具本体５に固着されている形状保持部材６とを具備しているために、装着時において不測の歪みを生じる虞をなくし得て、矯正すべき歯牙３に対して目的位置に向かう適切な圧力を与えることができ、而して、矯正すべき歯牙３を目的位置に効率よく移動させることができる。   According to the orthodontic appliance 1 of this example, the part 4 has a shape corresponding to the shape of the tooth 3 to be corrected while extending along the tooth row 2 so as to be detachable from the tooth row 2. However, the orthodontic appliance main body 5 arranged at a position corresponding to the target position where the tooth 3 should be arranged after correction, and the orthodontic appliance main body extending along the oral cavity and maintaining the shape of the orthodontic appliance main body 5 Since the shape holding member 6 fixed to 5 is provided, it is possible to eliminate the possibility of unexpected distortion at the time of mounting, and to apply an appropriate pressure toward the target position to the tooth 3 to be corrected. Thus, the tooth 3 to be corrected can be efficiently moved to the target position.

歯列矯正具１によれば、形状保持部材６は、マウスピース１１の両端又はその近傍を橋絡しているために、Ｕ字形状であるマウスピース１１の両端又はその近傍が互いに変位しないように当該マウスピース１１の歪みに抗する力を生じることができる。   According to the orthodontic appliance 1, since the shape maintaining member 6 bridges both ends of the mouthpiece 11 or the vicinity thereof, both ends of the mouthpiece 11 having a U shape or the vicinity thereof are not displaced from each other. In addition, a force that resists the distortion of the mouthpiece 11 can be generated.

歯列矯正具１によれば、形状保持部材５１が、マウスピース１１に沿う方向において間隔をもってマウスピース１１の内側の部位３１に固着されているために、マウスピース１１の微少な撓みを許容する一方、形状保持部材５１によりマウスピース１１の許容量以上の撓みを、例えばマウスピース１１の弾性力よりも大きな弾性力をもって禁止することができ、而して、装着者にマウスピース１１の異物感を与える虞を低減すると共に矯正すべき歯牙３を目的位置に効率よく移動させることができる。また、歯列矯正具１によれば、形状保持部材５２が、マウスピース１１に沿う方向において間隔をもってマウスピース１１の外側の部位３２に固着されているために、前記同様の効果を奏し得る。   According to the orthodontic appliance 1, since the shape holding member 51 is fixed to the inner portion 31 of the mouthpiece 11 with a space in the direction along the mouthpiece 11, a slight deflection of the mouthpiece 11 is allowed. On the other hand, the shape holding member 51 can prevent the mouthpiece 11 from being bent more than an allowable amount, for example, with an elastic force larger than the elastic force of the mouthpiece 11. The tooth 3 to be corrected can be efficiently moved to the target position. Further, according to the orthodontic appliance 1, since the shape holding member 52 is fixed to the portion 32 outside the mouthpiece 11 at intervals in the direction along the mouthpiece 11, the same effect as described above can be obtained.
