Research Abstract	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.
