Effect of denture base shape on facial cosmetic based on three-dimensional measurement of face

本研究的目的是利用三维数字立体摄影测量技术，研究义齿基托外形对单侧上颌骨缺损患者面部形态的影响。随着义齿基托厚度的增加，上颌骨缺损的面部皮肤当量明显移动。大肿胀假体的面部皮肤移位方向与正常及轻度肿胀假体有很大不同。

The purpose of this study was to investigate the effect of the outer-shape of the denture base on the facial morphology in a patient with unilateral maxillary defect by using a three-dimensional digital stereophotogrammetry. The facial skin equivalent of the maxillary defect moved significantly with increasing the thickness of the denture base. The direction of displacement of the facial skin with the greatly swollen prosthesis was quite different from with normal and slightly swollen prostheses.
