The influences of the retainer of the free end saddle partial denture to the abutment tooth were examined. When the distal rest was applied with bracing arm, it led to increase of the horizontal pressure to the abutment tooth. But the bracing arm in combination with mesial rest led the abutment tooth pressure to the tooth axis direction, and the horizontal direction pressure was reduced. It was suggested that the pressure of the denture abutment tooth tends to be affected by the position of the rest and the degree ofbracing action.

研究了自由端鞍座局部义齿固位体对基牙的影响。当远端支架与支撑臂一起使用时，会导致基牙的水平压力增加。而支撑臂与近中托相结合，将基牙压力引向牙轴方向，降低了水平方向压力。有人认为，义齿基牙的压力往往会受到托牙位置和支撑作用程度的影响。
