The present study measured the diametral compressive strength, flexural strength, and modulus of elasticity of composite resins used in inlay/onlay systems. The effect of additional curing also was determined. SR-Isosit material had the highest diametral compressive strength, and SR-Isosit-Dentin material had the lowest flexural strength. The SR-Isosit composite resins had lowest elastic modulus and Estilux posterior C VS resin the highest. A negative correlation was found between diametral compressive strength and elastic modulus of the materials. It was concluded that the additional curing of Brilliant resin did not result in improved mechanical properties. For Estilux resin, additional curing increased flexural strength and modulus of elasticity.
本研究测量了用于嵌体/高嵌体修复系统的复合树脂的径向抗压强度、抗弯强度和弹性模量。还确定了额外固化的效果。SR-Isosit材料的径向抗压强度最高，而SR-Isosit-Dentin材料的抗弯强度最低。SR-Isosit复合树脂的弹性模量最低，而Estilux posterior C VS树脂的弹性模量最高。研究发现材料的径向抗压强度与弹性模量之间呈负相关。得出的结论是，Brilliant树脂的额外固化并未导致机械性能的改善。对于Estilux树脂，额外固化提高了抗弯强度和弹性模量。
