At first, in this study, we confirmed that the patient face were measured exactly of patients by using non-cotact 3-D shape measurement apparatus with image encoder.To investigate exact changes of soft-tissue profile on midsagittal plane associated with the vertical and horizontal movement of mandible, the face of 15 women with normal occlusion were measured by using non-cotact 3-D shapemeasurement apparatus with image encoder. In the measurement, the mandible of the subjects were respectively induced with a bite plate, horizontally downward from centric position every 1mm (1-4mm), and forward every 1mm (0-7mm) from each downward position.After each 3-D data of facial soft tissue were overlapped by using FITTING PROBRAM (3D-SPHIIU), simple regression linear analysis was performed to obtain the regression formula which determines the 2-D movement of 21 points on soft-tissue profile of mid-sagittal plane to the movement of mandible.As the results of this study, exact ratios of soft tissue changes in relationship to the simple movement of mandible were clarified.On the basis of this result, we found the exact technic of post-operative soft-tissue profile prediction of patients with jaw deformity.

首先，在本研究中，我们使用带有图像编码器的非接触式三维形状测量仪对患者的面部进行了精确测量。采用带图像编码器的非接触式三维形状测量仪对15例正常咬合女性的面部进行了测量，以了解下颌正中矢状面软组织轮廓随上下运动的确切变化。在测量中，受试者的下颌骨分别用咬板诱导，从中心位置水平向下每1mm (1-4mm)，向前每1mm （0-7mm）。利用拟合PROBRAM （3D-SPHIIU）软件对面部软组织各三维数据进行重叠后，进行简单的回归线性分析，得到中矢状面软组织轮廓上21个点对下颌骨运动的回归公式。本研究的结果明确了软组织变化与下颌骨简单运动的确切比例。在此基础上，我们找到了准确预测颌骨畸形患者术后软组织形态的技术。
