摘要：当今，种植磁性覆盖义齿已广泛应用，是无牙颌患者的有效的治疗方法。种植覆盖义齿的普及创造了检查各种连接系统被使用的必要性，分配到牙槽骨的应力。因此，三文有限元进行分析在下颌骨应力分布与种植体支持的有球帽性和不同直径的磁性附着体覆盖义齿。一段下颌骨前牙区种植覆盖义齿进行。四种不同的模型生成具有球帽型和磁性附着体。从水平、垂直和倾斜方向分别施加10、35和70N的力，并研究了应力分布。得出的结论是压力最大浓度出现在皮质骨嵴可减少使用较小尺寸的高度，种植覆盖义齿。论文网

随着人类寿命的延长，很多人活得比他们的牙齿。对治疗老年患者，特别是那些残疾人，可能是一项艰巨的挑战。处理此类案件的最终目标是使患者恢复到一定水平的满意的美学，语音的生理功能、吞咽和咀嚼功能。完整的下颌义齿功能的问题，造成问题的最主要的原因是因为保留的很少。同时骨吸收明显的下颌骨比上颌骨牙多。由于全口义齿依靠残余牙槽嵴的支持和保留，这是最受影响的下颌义齿的自然过程。覆盖义齿可以作为一种治疗方式损害完全无牙颌患者尤其是下颌弓。整口覆盖义齿是通过种植体支持固位钉或磁性附着体是类似于天然牙的牙。植入物的最小数量的使用是足够的修复支持和保留也是经济效益的患者。
