摘要

目的:对比研究3种暂时冠桥材料的抗压强度

为临床应用提供实验依据。方法:参照GB/T7314-2005标准

制作直径12mm、高30mm的圆柱体试件18个

其中自凝树脂、Switf-Temp和ProtempⅡ各6个。采用MTS880万能材料试验机对试件进行加载并测定其抗压强度。结果:自凝树脂（215.67±22.66）MPa与Switf-Temp（110.19±18.57）MPa、ProtempⅡ（114.75±20.83）MPa的抗压强度比较有显著统计学差异（P<0.05）;而Switf-Temp与ProtempⅡ的抗压强度比较无统计学差异（P>0.05）。结论:自凝树脂的抗压强度高于Switf-Temp与ProtempⅡ。口腔医师应根据患牙的不同情况选用合适的暂时冠桥材料。

Abstract

Objective:To compare the compression strength of three provisional restorative materials. Methods:Eighteen cylinder specimens were fabricated with 12mm in diameter and 30mm in height according to the GB/T 7314-2005 standards. Six specimens were made of self-curing resin

Switf-Temp and Protemp Ⅱ respectively. Then all specimens were compressively loaded and the data were recorded by MTS880 testing machine. Results:There were significantly statistical differences (P<0.05) between self-curing resins (215.67 ± 22.66)MPa

Switf-Temp(110.19 ± 18.57)MPa and Protemp Ⅱ(114.75 ± 20.83)MPa

while nostatistical difference was found between Switf-Temp and Protemp Ⅱ (P>0.05)in terms of compression strength. Conclusion:The self-curing resins have higher compression strength than those of Switf-Temp and Protemp Ⅱ. The dentists must be aware of different situations of teeth and choose the provisional material appropriate for each tooth.
