title: [A study of changes in oral residual alveolar ridge under the partial denture bearing occlusal stress].
abstract: The change of oral residual alveolar ridge showing in X-ray films before and after wearing unilateral distal extension partial dentures for ten cases was observed by the image processing technique. It was demonstrated that the image processing technique is an available method for evaluating the degree of alveolar ridge resorption both quantatively and qualitatively. By the technique of pantomography of X-ray we can control the coincidence of the corresponding part of the X-ray film taking at different time. So we can use this method to study the regularity of the residual alveolar ridge resorption.
