抄録

Denture dynamics of the free-end saddle RPD (Removable Partial Dentures) should be made as low as possible in order to restore the stable occlusal contacts and protect both supporting tissues of abutments and residual ridges. Denture dynamics were directly affected by the connecting rigidity between the abutments and the denture saddles.<BR>In this study, the denture base supporting load ratio was analyzed in relation to the connecting rigidity in patients.<BR>Materials and Methods<BR>1. Layered leaf springs were utilized to measure displacement.<BR>2. Total occlusal load and denture sharing load were continuously measured when the connecting rigidity between the abutment and the denture saddle was changed.<BR>3. Denture sharing load to total occlusal force was calculated and analyzed.<BR>Results<BR>1. Continuous change of connecting rigidity was realized using layered leaf springs as connecting components of distal extension RPD.<BR>2. The more rigid the connection was, the less the denture base sharing load was.<BR>3. Denture base sharing load was associated with the increase in total occlusal load when the connecting rigidity was low.<BR>4. Denture base sharing load ratio to total occlusal load hardly showed any change when the connecting rigidity was over a certain level.<BR>Conclusion<BR>Connecting rigidity between abutments and denture saddle of distal extension RPD has a close relationship to the occlusal force distribution between abutments and residual ridges.
