The objective of this project, which was initiated from the Academy of Dental Materials, was to review and critically appraise methods to determine fracture, deformation and wear resistance of dental resin composites, in an attempt to provide guidance for investigators endeavoring to study these properties for these materials.
Test methods have been ranked in the priority of the specific property being tested, as well as of the specific test methods for evaluating that property. Focus was placed on the tests that are considered to be of the highest priority in terms of being the most useful, applicable, supported by the literature, and which show a correlation with clinical findings. Others are mentioned briefly for the purpose of being inclusive. When a standard test method exists, including those used in other fields, these have been identified in the beginning of each section. Also, some examples from the resin composite literature are included for each test method.
The properties for evaluating resin composites were ranked in the priority of measurement as following: (1) Strength, Elastic Modulus, Fracture toughness, Fatigue, Indentation Hardness, Wear-abrasion (third body) and Wear-attrition (contact/two body), (2) Toughness, Edge strength (chipping) and (3) Wear determined by toothbrush.
The following guidance is meant to aid the researcher in choosing the proper method to assess key properties of dental resin composites with regard to their fracture, deformation and wear resistance.
本项目由牙科材料学会发起，旨在回顾和批判性评估测定牙科树脂复合材料断裂、变形和耐磨性的方法，以便为致力于研究这些材料性能的研究人员提供指导。
根据所测试的特定性能以及评估该性能的特定测试方法，对测试方法进行了优先级排序。重点关注那些在实用性、适用性、有文献支持以及与临床结果相关方面被认为是最高优先级的测试。为了全面性，也简要提及了其他测试。当存在标准测试方法时，包括其他领域使用的方法，在各部分开头都已指明。此外，每种测试方法还包含了树脂复合材料文献中的一些示例。
评估树脂复合材料的性能按测量优先级排序如下：(1)强度、弹性模量、断裂韧性、疲劳、压痕硬度、磨损（三体磨损）和磨耗（接触/两体磨损），(2)韧性、边缘强度（崩裂），(3)牙刷磨损。
以下指导旨在帮助研究人员选择合适的方法来评估牙科树脂复合材料在断裂、变形和耐磨性方面的关键性能。
