Dentistry instrument tool, has with the mandibular bone integral returning/repeating vessel which multiplier effect works as a nose extended vessel and a snore prevention instrument inside the mouth. This dentistry instrument tool, it is round in the lower tooth the way, as it is formed, has the lower segment of the thermoplastic material which is connected to the upper division of the compound which extends with the upper jaw and the upper lip by the wire connector. The wire connector has the mechanism which makes the adjustment of positioning the mandible possible. Although the wire extended section which provides the acrylic pad for one end is connected by the median line of the flange, as for this wire extended section, the pad pulls the organization and the outer part nose wall of the lip and extends, obstructs the collapse which is in the midst of breathing, in order, front integral returning/repeating of the mandible to maintain opening the rear pharynx windpipe which is in the midst of sleeping which functioning is done as a snore prevention instrument it extends and has come out. As an additional use of the nose extended vessel inside the mouth, you can list the installation to the mouse guard for sport which uses the various materials.歯科用器具が、口内鼻拡張器と、いびき防止器具として相乗効果的に働く下顎骨整復器とを有する。この歯科用器具は、下歯に嵌まるよう形成されると共に上顎と上唇との間に延びる成形材料の上区分にワイヤコネクタにより連結された熱可塑性材料の下セグメントを有する。ワイヤコネクタは、下顎の位置決めの調整を可能にする機構を有する。一端にアクリルパッドを備えたワイヤ延長部は、フランジの正中線に結合され、このワイヤ延長部は、パッドが唇の組織及び外側鼻壁を引き伸ばし、呼吸中の虚脱を阻止する一方で下顎の前方整復がいびき防止器具として機能する睡眠中の後方咽頭気道の開放を維持するよう延び出ている。口内鼻拡張器の追加の用途として、種々の材料を用いたスポーツ用マウスガードへの組込みが挙げられる。
