Abstract
本研究目的在於探討新型人工牙根與支台齒之靜態破壞負載,進行植體與支台齒之應力分布研究,運用CAD電腦輔助設計新型人工牙根、支台齒模型,並佐以有限元素模擬分析技術,在靜態破壞負載模式下進行比較新型二階式人工牙根與不同的支台齒卡榫機構設計對於疲勞破壞界面之應力分析,並透過產品實測結果驗證有限元素模擬分析的合理性,以提供後續植體設計及疲勞測試之參考。依據ISO 14801: 2007標準規範設置人工牙根靜態負載模型,有限元素分析結果顯示,內六角型國維人工牙根,於不同負載所得之最大等效應力平均較內梅花型國維人工牙根降低31.53 %;實測結果顯示,內六角型國維人工牙根(???n3.5 mm × L13.5 mm)之靜態壓縮力平均值為1,120 ± 135.3 N,與內梅花型國維人工牙根(560 ± 88.9 N)結果比較,能提昇50 %之靜態壓縮力承載能力,綜合上述結果顯示內六角型設計之國維人工牙根能有效減少應力集中現象產生。
