Abstract
Excess removable partial denture dynamics during function may cause mechanical trauma on the abutments and the resorption of the residual ridges. A removable partial denture should be stabilized in the spatial position by the compensatory support due to the remaining abutments and the residual ridges. In this study, the mechanism to diminish the removable partial denture dynamics was investigated by annual review of selected dental literature.
Rigid bracing of the denture, rather than rigid retention, should be required with the stability of theremovable partial denture under the protection of abutments and residual ridges. Rigid bracing of the denturewill be obtained through connecting rigidity between abutments and retainers. Great connecting rigidity andbracing are obtained through the guiding surface/guiding plate parallelism between the abutments andretainers. The occlusal force distribution should be controlled by changing the connecting rigidity betweenabutments and removable partial denture.
