PROBLEM TO BE SOLVED: To provide a dental treatment wire in which three-dimensional translation is enabled without extracting a tooth in advance on the occasion of orthodontic treatment, and thereby root resorption can be prevented substantially completely and further the tissue may almost not be damaged.SOLUTION: A dental treatment wire 11 has a first portion 11a, a second portion 11b, a third portion 11c, an arch-shaped fourth portion 11d, a fifth portion 11e, a sixth portion 11f and a seventh portion 11g, and has a rectangular cross section of (0.41±0.05 mm)×(0.56±0.05 mm), and as a whole, is formed of an arch-shaped stainless steel wire. The first and seventh portions are positioned in a first plane, the second and sixth portions are positioned in a second plane, the third and fifth portions are positioned in a third plane, and the fourth portion is positioned in a fourth plane. The second plane is inclined to the first plane by 5° to 20°, the second plane is inclined to the third plane by 5° to 20° at the same side as the first plane, and the fourth plane is inclined to the third plane by 5° to 20° at the same side as the first plane, respectively.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】歯科矯正治療に際し事前に抜歯しないでも三次元的な歯体移動が可能となることにより、歯根吸収をほぼ完全に防止することができ、しかも組織にダメージをほとんど与えることがない歯科治療用ワイヤーを提供する。【解決手段】歯科治療用ワイヤー11は、第一部分11a、第二部分11b、第三部分11c、アーチ状の第四部分11d、第五部分11e、第六部分11fおよび第七部分11gを有し、(0.41±0.05mm)×(0.56±0.05mm)の長方形断面を有し、全体としてアーチ状のステンレス鋼製ワイヤーからなる。第一、第七部分は第一平面内に、第二、第六部分は第二平面内に、第三、第五部分は第三平面内に、第四部分は第四平面内に位置する。第二平面は第一平面に対し5°~20°、第二平面は第三平面に対し第一平面と同じ側に5°~20°、第四平面は第三平面に対し第一平面と同じ側に5°~20°それぞれ傾斜している。【選択図】図1
