材料学的发展促进口腔修复学的发展甚至飞跃,其中口腔传统修复材料影响口腔微生态的改变.近年来,许多学者对可摘局部义齿(removable partial dentures,RPDs)基托树脂的改性做出了大量研究.纳米粒子因具有光、磁、催化以及润滑等独特性质,作为填充材料有望提高材料的韧性、刚性及硬度,并同时具备抗菌性.因此,出现了许多改性RPDs基托树脂,其中之一是在树脂基托中加入纳米粒子添加剂以增强其抗菌性及机械性能,而良好的机械性能是RPDs发挥功能作用的前提保障.本文就加入纳米粒子添加剂后的RPDs基托树脂修复材料机械性能的研究进展综述如下,为口腔临床医生口腔修复材料的选择提供参考.“,”The development of oral prosthodontics were promoted by the material science,and the traditional oral repair material effecting oral ecological In recent years, a great deal of researchs on the modification of RPDs base resin have being processed . Nanoparticles as filling material can be expected to improve the toughness, rigidity and hardness of the material, and at the same time with antimicrobial properties for the unique characteristics of optical, magnetic, catalytic and lubrication. So one of the modification RPDs base resin was added nanoparticles to enhance its antimicrobial properties and mechanical properties, and good mechanical properties is the precondition of RPDs. In this paper, the mechanical properties of RPDs-based resin with nano-particle was reviewed, which can provide a reference to oral clinicians for the selection of dental restorative materials.
