目标。将一种新型硅烷基修复体材料与5种甲基丙烯酸酯基修复体材料--复合体、大聚体、纳米复合材料、杂化材料和微杂化材料--的物理性能进行比较。每种修复材料都检测了以下性能：压缩强度、径向拉伸强度、弯曲强度/弹性、断裂韧性、显微硬度和聚合收缩。每组测定平均值和标准差。对每个属性进行单因素方差分析/Tukey检验(α=0.05)。不同财产组之间存在显著差异(P<；0.001)。与甲基丙烯酸酯基修复体材料相比，新型硅烷基修复体材料的聚合收缩最小，但总体力学性能混合。与甲基丙烯酸酯基修复体材料相比，硅烷基修复材料具有相对较高的弯曲强度/弹性比、断裂韧性，但抗压强度和显微硬度较低。爱思唯尔有限公司代表牙科材料学会出版。
Objectives. To distinguish the physical properties of a new silorane-based restorative material in comparison to five methacrylate-based restorative materials - a compomer, giomer, nanocomposite, hybrid and micro-hybrid.Methods. The following properties were examined per restorative material: compressive strength, diametral tensile strength, flexural strength/modulus, fracture toughness, microhardness, and polymerization shrinkage. The mean and standard deviation were determined per group. A one-way ANOVA/Tukey was performed per property (alpha = 0.05).Results. Significant differences were found between groups per property (p < 0.001).Conclusions. Compared to the methacrylate-based restorative materials, the new silorane-based material had the lowest polymerization shrinkage, but an overall mixed mechanical performance. The silorane-based material had relatively higher flexural strength/modulus, fracture toughness, but relatively lower compressive strength and microhardness than the methacrylate-based restorative materials.
