Contemporary research in acrylic denture base materials focuses on the development of a novel poly(methyl methacrylate) (PMMA) resin with antimicrobial properties. Although PMMA resin has fulfilled all the requirements of an ideal denture base material, its susceptibility to microbial colonization in the oral environment is a formidable concern to clinicians. Many mechanisms including the absence of ionic charge in the methyl methacrylate resins, hydrophobic interactions, electrostatic interactions, and mechanical attachment have been found to contribute to the formation of biofilm. The present article outlines the basic categories of potential antimicrobial polymer (polymeric biocides) formulations (modified PMMA resins) and considers their applicability, biological status, and usage potential over the coming years.
当前关于丙烯酸类义齿基托材料的研究聚焦于开发一种具有抗菌性能的新型聚甲基丙烯酸甲酯(PMMA)树脂。尽管PMMA树脂已满足理想义齿基托材料的所有要求,但它在口腔环境中易被微生物定植,这是临床医生极为关注的问题。已发现包括甲基丙烯酸甲酯树脂中缺乏离子电荷、疏水相互作用、静电相互作用和机械附着在内的多种机制有助于生物膜的形成。本文概述了潜在抗菌聚合物(聚合物杀菌剂)配方(改性PMMA树脂)的基本类别,并考虑了它们的适用性、生物学状况以及未来几年的使用潜力。
