| 摘 要： | 目的：分析在冲击载荷下无牙下颌不同厚度黏骨膜能量缓冲能力的大小。方法：利用无牙下颌标准模型建立三维有限元模型，计算不同黏骨膜厚度时能量传递率的大小。结果：随着黏骨膜厚度的增加（0～5．0mm），黏骨膜能量传递率由100％降至22．55％。结论：黏骨膜的能量缓冲能力随着其厚度的增加而增大。

| Abstract: | Objective:To study the energy relieving effect of different thickness of mucosa beneath mandibular complete denture and try to analyze clinical question of prosthodontics using energy analysis methods.Method:A 3-dimensional finite element(3-DFE) model of the mandiblar complete denture and its supporting tissue were set up.Their rate of energy transferring were respectively caculated when mucosal thickness was different.Result:The mucosal rate of energy transferring descend from 100% to 22.55%,with its different thickness grow from 0mm to 5.0mm under punching loads.Conclusion:The energy relieving effect of mucosa grows with its thickness. |
