摘要：

背景：全口义齿是口腔修复临床工作中常见的一种修复形式，然而全口义齿上基托中间断面的早期断裂是影响全口义齿使用寿命的一个重要因素。
目的：从力学方面分析全口义齿的早期失效问题。
方法：通过对基托的受力分析、结构分析、材料性能分析，找出上基托中间断面早期断裂的真正原因，从而提出解决上基托中间断面早期断裂的新方法，提高全口义齿的疲劳强度，延长修复体的使用寿命。
结果与结论：采用现有的优质高疲劳强度的塑料制造基托的全口义齿，与用合金钢丝或铸钢制成基托骨架的全口义齿比较：①它有延长使用寿命的作用(一般说也不会有永久寿命)。②价格要低一倍或更多。③质量轻带上舒适。

Abstract:

BACKGROUND: The complete denture is a common repair form of prosthodontics clinical work, but the early fracture on the middle plate of complete denture is an important factor influencing the life of complete denture.
OBJECTIVE: To analyze the early failure of complete denture from a view of the mechanics.
METHODS: Based on the stress analysis, structural analysis, material property analysis of the plate, the real cause of early failure in the middle section was identified, thus proposing a new proposal to solve early fracture, improve fatigue strength of complete denture, and extend the service life of complete denture.
RESULTS AND CONCLUSIONS: The existing plastic manufacturing complete denture of high quality and high fatigue strength was superior to plate skeleton complete denture made of alloy steel or cast steel in the following aspects: ① prolonging the service life (generally permanent life is not available); ② reducing prices by 100% or lower; ③ comforting due to small quality.
