The three-dimensional finite element stress analysis method was used to determine the distribution of stresses in and around a model of six implants which supported a typical fixed complete-arch prosthesis in a simulated human mandible. A load of 100 N was applied at different intervals along the cantilever segment. There was a decrease of stress that reached a minimal level at 15 mm along the cantilever segment. Thereafter, a progressive increase of stresses in the lingual and buccal plates was demonstrated.
采用三维有限元应力分析方法,确定在模拟人类下颌骨中支持典型固定全牙弓修复体的六个种植体模型内部及周围的应力分布。沿悬臂梁段在不同间隔处施加100 N的载荷。沿悬臂梁段在15 mm处应力降低至最低水平。此后,舌侧板和颊侧板中的应力逐渐增加。
