摘　　要：目的:探讨二期高温高压处理对Ceramage瓷聚体材料机械性能的影响。方法:用Ceramage瓷聚体材料分别制作20个抗压强度和直径拉伸强度测试试件,所有试件在Solidilite光聚合器中常规聚合,而后随机分为两组,一组为对照组,另一组用国产自控多用途牙用树脂聚合器进行二期热压处理,温度120℃,压力0.6 MPa,时间7 min;用Bose公司ElectroForce3520多功能材料实验机测得抗压强度和直径拉伸强度,对二期热压处理前后的测试值用单因素方差分析进行比较。结果:二期热压处理后Ceramage瓷聚体的抗压强度和直径拉伸强度都有了显著提高,提高幅度分别为12.90%和10.84%(P<0.01)。结论:二期热压处理可以明显提高Ceramage瓷聚体材料的抗压强度和直径拉伸强度。Objective：To explore the mechanical characteristic effects of secondarily treated on Ceramage ceramic optimized polymer material.Method：20 compress strength specimens and 20 diameter tensile strength specimens were made with Ceramage ceramic optimized polymer material.In each group 10 specimens cured in Solidilite light-curing case,the others were treated secondarily after cured in Solidilite,with the condition of 120 ℃,0.6 Mpa and 7 min.All specimens were tested with Bose ElectroForce 3520 type tensile testing machine.Result：The compressive strengths and diameter tensile strengths had significantly increase after secondarily treatment（P 〈0.01）,with increment of 12.90 % and 10.84 %.Conclusion：Secondarily treatment with high temperature and press can significantly improve the compressive strengths and diameter tensile strengths of Ceramage ceramic optimized polymer material.
