背景:复合树脂作为一种既美观又实用的嵌体修复材料,其机械性能的改进成为研发的热点。目的:用CERAMAGE与TESCERA两种嵌体固化机制作树脂试件,比较两种加工技术对嵌体材料机械性能的影响。方法:选取两种机器的配套树脂,与两种机器进行交叉配对,分成4组:A、B两组用Tescera树脂分别与TESCERA嵌体机和CERAMAGE嵌体机配对;C、D两组用Ceramage树脂分别与CERAMAGE嵌体机和TESCERA嵌体机配对,分别制作标准试件,测试试件的表面硬度,抗压强度和挠曲强度。结果与结论:在表面硬度,抗压强度上,A组高于其他3组;B组高于C、D两组(P<0.05)。在挠曲强度上,C、D两组高于A、B两组(P<0.05),C、D组间及A、B组间差异无显著性意义。结果表明,用TESCERA嵌体机加工其配套树脂,所得试件的机械性能最佳。
Background: As an attractive and practical inlay repair material, composite resin has become a hot spot in the research and development of its mechanical properties. OBJECTIVE: To make the resin specimen with CERAMAGE and TESCERA two kinds of inlay curing machines, and compare the effects of two processing techniques on the mechanical properties of inlay materials. Methods: The resin of two kinds of machines was selected and cross-paired with two kinds of machines and divided into four groups: group A and group B were respectively matched with TESCERA inlay machine and CERAMAGE inlay machine in group A and group B; Respectively, the resin is matched with the CERAMAGE inlay machine and the TESCERA inlay machine respectively to prepare standard test pieces for testing the surface hardness, compressive strength and flexural strength of the test pieces. RESULTS AND CONCLUSION: In surface hardness and compressive strength, group A was higher than the other three groups; group B was higher than group C and D (P <0.05). Flexural strength, C, D two groups was higher than A, B two groups (P <0.05), C, D group and A, B group no significant difference between. The results show that, with TESCERA inlay processing of its resin, the resulting specimen best mechanical properties.
