| 摘 要： | 目的:探讨预防磁性附着体义齿折裂的措施和方法。方法:选择17例病例,分成A、B2组,A组9例,采用常规树脂基托;B组8例,在树脂基托中设计金属支架。随访3～5a,观察基托隐裂或折断的发生率,采用χ2检验进行统计学处理。结果:A组有3例基托发生折断,B组均未发生。两组间存在显著差异(P<0.05)。结论:金属支架能够显著提高树脂基托的抗力,易于制作和应用,可获得良好的临床效果。

| Abstract: | PURPOSE: To investigate the methods to prevent magnetic denture from fracture. METHODS: 17 cases were selected and divided into group A and group B. 9 cases in group A only used resin base, 8 cases in group B were strengthened with frameworks. The rates of fracture or fissure in denture base were observed for 5 years, Chi(2) test was used for statistical analysis. RESULTS: In group A, 3 cases were found with damaged base, there was no fracture happened in group B. Chi(2) test showed that there was significant difference between the two groups (P<0.05). CONCLUSION: Frameworks should be designed to improve the strength of the magnetic denture base. It is easy to manufacture and apply with satisfactory clinical effects. |
