摘要
通过运用三维有限元方法建立Ⅰ-Ⅳ类骨质中种植体不同角度倾斜种植模型24个,垂直集中加载300 N。分析研究显示,在同一骨质中,随着种植体倾斜角度的增加,密质骨和松质骨中的最大应力及应变量均逐渐增大;而相同角度的种植体于不同质量的颌骨中时,最大应力发展趋势为:密质骨:Ⅳ类骨质〉Ⅲ类骨质〉Ⅱ类骨质〉Ⅰ类骨质;松质骨:Ⅲ类骨质〉Ⅳ类骨质〉Ⅱ类骨质。
24 different inclined angle implant models in different types of bone were established by using three-di-mensional finite element method, vertical loading 300N. The final analysis result was: with increase of implant tilt-ing angle in the same types of bone, the maximum stress and strain of both compact bone and cancellous bone rised gradully. However, when the same angle implant applied to different type of jaw, development trend of maximum stress and strain were:compact bone:Type Ⅳ 〉 Type Ⅲ 〉 Type Ⅱ 〉 Type Ⅰ;cancellous bone:Type Ⅲ 〉 Type Ⅳ〉 Type Ⅱ.
