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。
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, X^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. X^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, Supported by Research Fund of Science and Technology Committee of Shanghai Municipality （Grant No.964419041）.
