発明の技術分野
本発明は、歯列保護矯正具に関し、さらに詳しくは、各
個人の歯列に応じた形状に変形が容易な歯列保護矯正具
に関する。TECHNICAL FIELD OF THE INVENTION The present invention relates to an orthodontic appliance, and more particularly to an orthodontic appliance that can be easily deformed into a shape suitable for each individual's dentition.
発明の技術的背景
ボクシング、アメリカンフットボールなどの激しい動作
を伴うスポーツでは、歯列を保護するためそして脳への
衝撃を緩和するため、一般にマウスピースと呼ばれてい
る歯列保護具が広く用いられている。Technical Background of the Invention In sports that involve strenuous movements such as boxing and American football, teeth protectors, commonly called mouthpieces, are widely used to protect the teeth and reduce the impact on the brain. ing.
また歯列の噛合状態が不充分である患者の歯列噛合状態
を改善するため、歯科医院では歯列矯正具が用いられて
いる。In addition, orthodontic appliances are used in dental clinics to improve the occlusal state of the dentition of patients whose dentition is insufficiently occlusal.

加された酢酸ビニル樹脂から形成された歯列保護矯正具
は、たん加熱して軟化させた後に温度が比較的高いうち
に速やかに噛んで変形させなければならない。By the way, the above-mentioned orthodontic protective orthodontic devices have conventionally been made of vinyl acetate resin to which a plasticizer has been added. Such orthodontic orthodontic appliances are generally heated and softened, and then
Before it hardens, it is chewed with the teeth and transformed into a shape that suits each individual's teeth. However, orthodontic orthodontic appliances made of vinyl acetate resin to which a plasticizer has been added must be heated to soften them and then quickly chewed to deform them while the temperature is relatively high.
なぜならもし温度が下がった後に噛んだのでは、歯列保
護矯正具はかなり硬化してしまい、各個人の歯列に応じ

ほどに硬化してしまうまでの時間が短いため、着用者に
は不便であった。This is because if the teeth are chewed after the temperature has dropped, the teeth-protecting orthodontic device will harden considerably and it will be difficult to transform it into a shape that suits each individual's dentition. For this reason, orthodontic orthodontic appliances made of vinyl acetate resin with added plasticizers must be chewed to deform them while they are still hot after heating, and furthermore, they harden to the point that they cannot be deformed after being heated and softened. It was inconvenient for the wearer because it took only a short time to wear off.

保護矯正具を提供することを目的としている。Purpose of the Invention The present invention aims to solve the problems associated with the prior art as described above. Orthodontic protective orthodontics that do not require the protective orthodontic appliance to be heated and softened and then chewed to deform it while it is still hot, and that it takes a long time to harden after being heated and softened, so that it is easy to handle. The purpose is to provide tools.
