种植全口覆盖义齿侧方和前伸咬合平衡者均较不平衡者骨界面应力明显降低。
To the osseointegrated implant-supported overdenture, its stresses in protrusive and lateral balanced occlusions were lower than those in their unbalanced ones.
方法：建立种植全口固定义齿和种植全口覆盖义齿的三维有限元模型，然后进行侧方咬合平衡与不平衡、前伸咬合平衡与不平衡模拟加载分析。
METHODS: A 3-D finite element model of mandibular complete dentures supported by implants was established to analyze the stress status with protrusive or lateral occlusions.
