OBJECTIVE
To collect and analyze the Three-dimensional (3D) facial profile variation of edentulous patients restored by complete denture.
METHODS
The 3D facial images of 20 Atwood Class II edentulous patients were taken by DSC-2 3D facial imaging system before and after restoration of complete denture. Then, the two 3D facial images of each patient before and after restoration were registered in the same coordinate system by partial structure overlap. The differences between these two 3D facial images were statistically analyzed.
RESULTS
The major facial profile variation of Atwood Class II edentulous patients restored by complete denture focused in the area around the upper lip and the corner of the mouth. The change of lower lip and chin area was not obvious. The shift in the sagittal direction was significantly more evident than that in the vertical direction, while the shift in the horizontal direction was the least one.
CONCLUSION
The pattern of facial profile variation of edentulous patients restored by complete denture based on 3D imaging may provide reliable data support for prediction and communication in clinical practice.
目的
收集并分析全口义齿修复无牙颌患者的三维（3D）面部轮廓变化。
方法
采用DSC - 2三维面部成像系统，采集20例阿特伍德II类无牙颌患者全口义齿修复前后的三维面部图像。然后，通过部分结构重叠将每位患者修复前后的两幅三维面部图像在同一坐标系中配准。对这两幅三维面部图像之间的差异进行统计学分析。
结果
全口义齿修复的阿特伍德II类无牙颌患者主要面部轮廓变化集中在上唇及口角周围区域。下唇及下巴区域变化不明显。矢状方向的移位明显比垂直方向更显著，而水平方向的移位最小。
结论
基于三维成像的全口义齿修复无牙颌患者面部轮廓变化模式可为临床实践中的预测和沟通提供可靠的数据支持。
