Planning a treatment strategy at orthodontic treatment, the position of the teeth play a very important role and both pressures and toniciry of tongue and lip are usually considered as a major element of it. However, this kind of estimations are usually done subjectively and qualitatively without using some devices to evaluate these objectively. From mis point of view, the establishment of methodology to evaluate the hardness and the tonicity of a lip and tongue are really needed. The purpose of this study was to construct a database with measuring and evaluating the tonicity and hardness of the soft tissues by using of newly developed vibration sensor and torque sensor.The results obtained were as follows:1) Nose and Chin were the hardest, the next followed Tongue and Cheek, and Lip was softest.2) The hardness of soft tissues at a male was generally harder compared with that of a female.3) Cl.III malocclusion showed a softer tendency.4) The tonicity was lowest at Chin, and highest at Tongue.5) Female showed a lower tonicity at Nose, Chin and Cheek, on the other hand, male showed a lower tonicity at Tongue and Lip.6)At cl.III malocclusion, the tonicity was generally lower, but higher at cl. II.These newly developed systems would contribute to the objective evaluation of hardness and tonicity of the soft tissues.

在正畸治疗中制定治疗策略时，牙齿的位置起着非常重要的作用，舌和唇的压力和张力通常被认为是其中的主要因素。然而，这种估计通常是主观和定性的，没有使用一些设备来客观地评估这些。从我们的角度来看，确实需要建立评估唇舌硬度和张力的方法。本研究的目的是利用新开发的振动传感器和扭矩传感器构建一个测量和评估软组织张力和硬度的数据库。获得的结果如下：1）鼻子和下巴最硬，其次是舌头和脸颊，嘴唇最软。2）男性软组织硬度普遍较女性硬。3）Cl.III错牙合表现出较软的趋势。4）下巴张力最低，以及最高的5) 女性在鼻子、下巴和脸颊处表现出较低的张力，而男性在舌头和嘴唇处表现出较低的张力。6) 在 cl.III 错牙合畸形中，张力普遍较低，但在 cl.III 错牙合畸形中张力较高。 。 II.这些新开发的系统将有助于客观评估软组织的硬度和张力。
