摘要：

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。

Abstract:

BACKGROUND: Composite resin functions as a practical resin restoration material with beautiful outlook, modifying its mechanical properties has become a hot spot in research.
OBJECTIVE: To prepare resin specimens with two kinds of inlay curing machines: CERAMAGE and TESCERA, and to compare the mechanical properties of these specimens.
METHODS: The resin specimens supporting two machines were cross-matched with these machines and then divided into four groups: Group A was Tescrea resin prepared with TESCERA machine; group B was Tescrea resin prepared with CERAMAGE machine; group C was Ceramage resin prepared with CERAMAGE machine; group D was Ceramage resin prepared with TESCERA machine. The standard specimens were determined for compressive strength, hardness and flexural strength. 
RESULTS AND CONCLUSION: The compressive strength and hardness in group A were higher than those in other three groups, and group B exhibited higher compressive strength and hardness than groups C and D (P < 0.05). The flexural strength in groups C and D was higher than that in groups A and B (P < 0.05), there was no significant difference between groups C and D, neither betweens group A and B. The experimental findings indicate that TESCERA inlay machine and Tescera resin achieve the optimal mechanical properties.
