Free-end saddle removable partial denture is an alternative to prevailing implant prostheses to restore the lost occlusal function. Occlusal stress distribution in free-end saddle RPD has been discussed by many prosthodontists. This problem of stress distribution must be recognized because of further application of free-end saddle RPD, realizing the limitation of its use. In this study, stress distribution in both abutment teeth and residual ridges were measured, analyzed, and discussed.<BR>The results were as follows:<BR>1. Selection of retainers influenced the occlusal force distribution even in the same free-end saddle condition.<BR>2. Occlusal force distribution in the free-end saddle was closely related to the connecting rigidity of the selected retainer. The higher the connecting rigidity was, the less the denture sharing load was.<BR>3. Abutment tooth mobility did not show any difference among the three different retainers assessed.<BR>4. Mucosal support was suggested to be important for sharing the occlusal force applied in even the rigid telescope retainer under various conditions.
