 note = {P(論文), The purpose of this laboratory study was to clarify the effects of sagittal inclination of residual ridges to abutment tooth movement when the locations of indirect retainers used for the cross arch stabilization were altered. Three mandibular test models simulating a free-end saddle were used in this study. The sagittal angulation of the posterior residual ridges were +15 degrees, zero angulation, and -15 degrees. The chrome-cobalt removable partial denture castings were fabricated in the usual procedure. The component parts of the removable partial denture were metal base with loading platforms, Akers clasp on the abutment tooth, indirect retainers (double Akers's clasp type on teeth Nos. 44, 45 and Akers' clasp type on teeth Nos. 44,47), and a lingual bar. The loading apparatus was used to apply uniform loads. Each partial denture was seated with a 2 kgfload. The movement of abutment tooth was magnified using indicator rod attached to the abutment tooth. Sirognatho analizer system was used to analyze the direction and magnitude of abutment tooth movement. The results were as follows. 1. The inclination of the residual ridge affects the direction and magnitude of abutment tooth movement. 2. The direction of abutment tooth movement was disto-lingual. 3. When comparing +15, zero, and -15 degrees angulation of residual ridge, -15 degrees angulation of residual ridge produced greatest abutment tooth movement for distal. 4. Abutment tooth movement under the indirect retainers of Akers' clasp on teeth Nos. 44, 47 was smaller in many directions when compared with the indirect retainers of double Akers' clasp on teeth Nos. 44, 45.},
