Management of loading forces on mandibular distal-extension prostheses. Part II: Classification for matching...

When a mandibular distal-extension removable partial denture is planned, consideration should be given to the capacity of the supporting structures to accept the functional loading of the prosthesis. To prescribe a treatment modality that will not cause their breakdown, an analysis should be made of the relative strength and weakness of the ridges and abutment teeth. This judgment can be visualized by classifying partially edentulous jaws into one of the four categories that are possible when the two key factors of ridge resistance and abutment teeth are combined.
