次に、本実施形態の歯列矯正装置１０の作用について説明する。   Next, the operation of the orthodontic device 10 of the present embodiment will be described.

まず、上歯２の前歯３及び奥歯４を本体部２１で覆うようにマウスピース２０を装着する。次いで、拡大床３０の左右の固定ワイヤ３１，３１を奥歯４の左右の歯冠部に対応したマウスピース２０の上からそれぞれ掛止することで、マウスピース２０の奥歯４の左右の歯冠部間に装着する。   First, the mouthpiece 20 is attached so that the front teeth 3 and the back teeth 4 of the upper teeth 2 are covered with the main body 21. Next, the left and right fixing portions 31 of the enlarged floor 30 are respectively hooked from above the mouthpiece 20 corresponding to the left and right crown portions of the back teeth 4, so that the left and right crown portions of the back teeth 4 of the mouthpiece 20. Attach in between.

ところで、マウスピース２０は、上述したように前歯３の歯列を比較的長い期間を要せずに矯正することができるものの、奥歯４の歯列を横方向に拡げる力が弱いため、奥歯４の歯列を矯正するのに長い期間を要する。   As described above, the mouthpiece 20 can correct the dentition of the front teeth 3 without requiring a relatively long period of time, but the mouthpiece 20 has a weak force to expand the dentition of the back teeth 4 in the lateral direction. It takes a long time to correct the dentition.

また、拡大床３０は、上述したように奥歯４の歯列を横方向に短期間で拡げることができるものの、装着していない期間が長いと、矯正された歯列が矯正前の叢生状態に戻り易いという不具合があり、また歯と歯との間隔が広くなりすぎる場合がある。しかし、拡大床３０は、連続して長時間装着すると、口腔１内において舌への違和感が大きいという問題がある。   In addition, as described above, the enlarged floor 30 can expand the dentition of the back teeth 4 in the lateral direction in a short period of time, but if the non-attachment period is long, the corrected dentition becomes a crowded state before the correction. There is a problem that it is easy to return, and the distance between the teeth may be too large. However, when the enlarged floor 30 is worn continuously for a long time, there is a problem that a feeling of strangeness to the tongue is large in the oral cavity 1.

そこで、本実施形態では、例えばマウスピース２０は、常に装着しておき、拡大床３０は、就寝時や週末及び休日に装着する。すると、拡大床３０によって歯列を短期間で矯正することができる。そして、拡大床３０を取り外した場合でも、矯正された歯列がマウスピース２０によって矯正前の叢生状態に戻ることがなく、矯正した綺麗な状態の歯列を維持することができる。   Therefore, in the present embodiment, for example, the mouthpiece 20 is always worn, and the enlarged floor 30 is worn at bedtime, on weekends, and on holidays. Then, the dentition can be corrected by the enlarged bed 30 in a short period of time. Then, even when the enlarged bed 30 is removed, the corrected dentition does not return to the crowded state before the correction by the mouthpiece 20, and the corrected dentition can be maintained in a beautiful state.

このように本実施形態の歯列矯正装置１０によれば、マウスピース２０が少なくとも奥歯４を覆うように装着され、このマウスピース２０が装着される部位に拡大床３０が着脱自在に装着されるため、拡大床３０により歯列の矯正期間を短縮化し、かつ矯正した綺麗な状態の歯列をマウスピース２０により維持することが可能になる。   As described above, according to the orthodontic device 10 of the present embodiment, the mouthpiece 20 is attached so as to cover at least the back teeth 4, and the enlarged floor 30 is detachably attached to a portion where the mouthpiece 20 is attached. Therefore, it is possible to shorten the orthodontic period by the enlarged bed 30, and to maintain the orthodontic and clean dentition by the mouthpiece 20.

また、奥歯４の歯列を横方向に短期間で拡げることができるので、叢生状態の歯を矯正するために抜歯することがなくなり、各個人の負担を減らすとともに、上顎前突も矯正することができる。加えて、マウスピースの使用回数や使用段階数を減少させることができるため、経済性に優れた歯列矯正装置１０を提供することができる。   In addition, since the dentition of the back teeth 4 can be expanded in the lateral direction in a short period of time, there is no need to perform tooth extraction to correct the crowded teeth, reducing the burden on each individual and correcting the maxillary protrusion. Can be. In addition, since the number of times of use and the number of stages of use of the mouthpiece can be reduced, it is possible to provide the orthodontic appliance 10 excellent in economy.

さらに、本実施形態の歯列矯正装置１０によれば、拡大床３０は、左右の奥歯４の歯冠部に対応したマウスピース２０にそれぞれ装着される左右の固定ワイヤ３１，３１と、左右の固定ワイヤ３１，３１がそれぞれ取り付けられた左右の床部３２，３２と、左右の床部３２，３２及び左右の固定ワイヤ３１，３１を介して左右の奥歯４の位置を拡大する拡大ねじ３３と、を備えるため、既存のタイプの拡大床を用いることができる。その結果、経済性に優れた歯列矯正装置１０を提供することができる。
