义齿基托塑料断裂、折裂是口腔修复临床最常见的问题．从简化工艺、病人舒适，成型方便等方面考虑，研制高强度的基托材料，实属最佳选择方案．本研究以现行常见口腔高分子材料为基础，研究了添加增韧剂的各种配方．研究结果表明：在现义齿基托的体系中添加一定量的甲基丙烯酸八氟戊酯（８ＦＭＡ），基托材料的冲击强度可达６．０２ｋＪ／ｍ￣２，抗弯强度达５８．５ＭＰａ，与现行材料相比，分别提高３６．６％和１８．４％，成型简便，工艺性能优良，可试用于临床，进行疗效观察．
Denture base plastic fracture, fracture is the most common clinical oral repair problems. From the simplification of technology, patient comfort, ease of molding and other considerations, the development of high-strength base material, it is the best choice. Based on the current common oral polymer materials, various formulations of toughener were studied. The results show that adding a certain amount of octafluoropentyl methacrylate (8FMA) in the denture base system, the impact strength of the base material up to 6.02kJ / m ~ 2, the bending strength of 58.5MPa , Compared with the current materials, respectively, increased by 36.6% and 18.4%, forming simple, excellent process performance, can be used in clinical trials, the efficacy observed.
