• Interrelationships between mandibular bone reduction and morphological features of craniofacial skeleton was fundamentally demonstrated in this study. Forty-nine denture wearers were engaged in this research as edentulous subjects, and categorized into three groups based upon their resorption points on radiographic and cephalometric views. Cephalometric landmarks and lines after Downs and Ricketts were independently employed in informations of multivariate data base, and the data were analyzed in components and summarized as follows : Ricketts' landmarks were more advisable to prosthetic applications than Downs' anatomical ones. The resorption peaks shifted forward as mandibular reduction increased. Mental regions were shifted "forward-upward" as longitudinal reductions progressed. Sharp angles and narrow rami were induced by apparently resorption of mandibles.
