Using a laboratory model simulating a free-end saddle partial denture situation, the effect of variation of the angulation of the crest of the residual alveolar ridge to the horizontal on movement of the abutment tooth and saddle was observed. It was found that the inclination of the residual ridge affected the direction and magnitude of abutment tooth movement. The direction of abutment tooth movement was not related to the position of the occlusal rest. However, the magnitude of saddle and abutment tooth movement is affected by the design of the clasp used.
利用模拟游离端鞍式局部义齿情况的实验室模型,观察了残余牙槽嵴顶与水平面角度变化对基牙和鞍基移动的影响。发现残余牙槽嵴的倾斜度影响基牙移动的方向和幅度。基牙移动的方向与支托的位置无关。然而,鞍基和基牙移动的幅度受所用卡环设计的影响。
