A term "Denture Dynamics" was originally defined as a denture movement during function by K. H. Korber, which was expanded to express the stability of occlusal contacts built on artificial teeth of removable partial dentures (RPDs) through the function of the compensatory support, bracing and retention derived from the abutment teeth and the residual ridges during mastication affected by denture movement, especially in distal extension saddle RPDs, in this paper.<BR>The rigid support concept of the distal extension RPDs were analyzed on the basis of EBM. For the purpose of exact and long-lasting occlusal contact with RPDs, attention should be paid to realize the followings:<BR>1. Denture movement in distal extension RPDs should be minimized to the extent of the minimal movement of the expanded saddle for the exact reconstruction of occlusal contact with as simple outline form as possible.<BR>2. First, choose the direct retainers with sufficient connecting rigidity for minimizing the denture movement with the healthy periodontal tissues of the abutments after extensive mouth preparations on the basis of sufficient tissue support and bracing.<BR>3. Broken stress design of low connecting rigidity RPDs are rarely indicated with poor abutments after extensive periodontal therapy, or with weak devitalized abutments.
