Asymptotic Solutions OF Helmholtz's Equation Near A Cusped Caustic 赫姆霍兹方程在尖点聚焦面邻近的渐近解
Methods: The implant prosthesis and the supporting bone models under the different cusped that were 30 degree, 20 degree and 0 degree occlusal, registered simulate mastication movement and the load needing and the meet an emergency. 方法:制作种植义齿及支持骨模型,冠修复体设计成0、20、30不同牙尖斜度。记录模拟咀嚼运动所需的载荷及所产生的应变。
