Abstract

The aim of this in vitro study was to analyze, both experimentally and theoretically, the mechanical behavior of two types of composite materials used in restoring dental integrity. The samples of each composite resin, namely Filtek Supreme XT (3M ESPE, St. Paul, MN, USA) and Filtek Z250 (3M ESPE, St. Paul, MN, USA), were experimentally analyzed by determining their compressive strength and fracture behavior. The fractured fragments of the samples were subjected to surface evaluation by scanning electron microscopy. The compressive stress-compressive strain dependencies revealed stronger cracking of the Filtek Supreme XT composite than Filtek Z250 prior to fracture. Theoretically, the evaluation was made by means of holographic implementations of such types of composite materials. A Hooke-type equation in a differential form is presented, which links the proposed theoretical model with the experimentally obtained data.

摘要

本体外研究旨在通过实验和理论分析，研究两种用于修复牙体完整性的复合材料的力学性能。对每种复合树脂（即 Filtek Supreme XT [3M ESPE，明尼苏达州圣保罗]和 Filtek Z250 [3M ESPE，明尼苏达州圣保罗]）的样本进行了实验分析，以确定其抗压强度和断裂行为。对样本的断裂碎片进行了扫描电子显微镜表面评估。压缩应力-压缩应变关系表明，在断裂之前，Filtek Supreme XT 复合材料比 Filtek Z250 更容易出现裂纹。从理论上，通过对这种类型的复合材料进行全息实现来进行评估。提出了一个微分形式的胡克型方程，将所提出的理论模型与实验获得的数据联系起来。
