PROBLEM TO BE SOLVED: To provide a dental treatment tool in which a main portion of a fan of a foot rest capable of placing patients feet in a wide angle is formed in a vertically swingable manner and an own weight drop containing a patients body weight is instantaneously stopped by a cradle and an abutment body after raising patients heel sides, and thereby the impact of the own weight drop is imparted in a concentrated manner from heels to a pelvis and an occlusion balance effect can be connected to an improvement effect of distortion of the pelvis and spine in a short time, resulting in causing occlusion displacement.SOLUTION: A dental treatment tool concerning the present invention is characterized in that a substantially fan-shaped left and right foot rests are disposed on a base in a swingable manner while leading edge portions of fans are faced outward to each other, and an abutment body collides with a cradle and impact is repeatedly imparted to the main portion of the fan of the foot rest when a foot rest descends by own weight containing a patients body weight.COPYRIGHT: (C)2015,JPO&INPIT【課題】患者の足を広角度に載置できる足置台の扇の要部分を上下揺動自在とし、患者の踵側を上昇させた後に患者の体重を含む自重落下を受台と当接体とで瞬間的に停止させ、自重落下の衝撃を踵から骨盤にかけて集中して付与し、短時間で咬合バランス効果を骨盤や背骨の歪みの改善効果につなげ、咬合ズレを生起させることができる歯の治療具を提供する。【解決手段】本発明に係る歯の治療具は、略扇形状の左右足置台を互いに扇の先縁部分が外方を向いた状態で基台に揺動自在に配置し、足置台が患者の体重を含む自重により降下する際に当接体が受台に衝突して足置台の扇の要部分に衝撃を繰返して付与する構成としたことを特徴とする。【選択図】図1
