Description

一种新型口腔义齿材料及其制备方法
技术领域
本发明属于医用高分子技术领域,涉及一种新型口腔义齿材料及其制备方法。
背景技术
PMMA(聚甲基丙烯酸甲酯)是口腔科常用的修复材料,主要应用于活动义齿的基托、人造牙、临时冠、桥、个别托盘、正畸活动矫治器、传统颌垫、传统保持器等,因其具有适应症广泛、价格低廉、不伤及邻牙、容易修理等优点,是目前常用的修复材料,但是其耐磨性差,强度不足,常造成义齿的过度磨损、老化和断裂,使其寿命一般在5-8年;同时无抗菌性,容易患龋,引起牙龈炎、牙周炎及口腔软组织炎症等,在使用中给患者带来不便。
对于其改性,主要是提高其机械性能和抗菌性能,目前常通过增加金属增强物、纤维或无机纳米粒子来进行改性。金属的加入会影响义齿的色泽,降低其实用性;纤维可以增强其机械性能,但制作工艺要求较高,工业化生产困难;无机纳米粒子填料主要有CaCO3,SiO2,Ag2O,Al2O3等,这些粒子极易发生团聚从而使纳米材料的优点不能很好地表现出来,同时会影响其色泽。
石墨烯具有优异的导热、导电和力学性能,同时具有良好的生物相容性、热稳定性、化学稳定性和抗菌性,近年来倍受材料界的关注。其衍生物包括氧化石墨烯、氮化石墨烯、溴化石墨烯、氟化石墨烯等,这些衍生物不仅保留了石墨烯的优良特性,而且具有各自的独特性质。有报道将氧化石墨烯添加到PMMA中增加PMMA的力学性能,但所得材料色泽不稳定,影响美观,其临床实用性不足。氟化石墨烯是将氧化石墨烯在高温高压下氟化制得,其表面有大量C-F键、羟基、环氧基、羧基等活性官能团,而且氟化石墨烯是白色,其分散液呈透明状,不影响义齿的色泽。
发明内容
本发明的目的是提供一种具有抗菌性、优异的耐磨性、抗老化性、生物相容性和美观性的新型口腔义齿材料及其制备方法。
本发明将白色的氟化石墨烯(FG)添加到聚甲基丙烯酸甲酯(PMMA)粉剂中制备了新型口腔义齿材料,使其比目前临床使用的义齿材料具有更加优异的耐磨性、抗老化性和生物相容性,具有极强的抗菌性,并且色泽美观,临床使用性强。
一种新型口腔义齿材料,其特征在于该材料由98 wt%-99.9 wt %的聚甲基丙烯酸甲酯和0.1 wt%-2 wt %的氟化石墨烯组成,其中氟化石墨烯中氟元素的质量百分比大于20%。
如上所述新型口腔义齿材料的制备方法,其特征在于具体步骤为:
将FG加入无水乙醇超声分散2-4 h,与PMMA粉剂混合,在研钵中研磨均匀并使乙醇挥发完全,所得粉末分散在无水乙醇中超声30-120 min,再次研磨至乙醇挥发完全,得到PMMA/FG混合粉剂。
本发明具有以下优点:
1、本发明所用的制备方法简单,设备简单,易于大规模推广。
2、本发明所制得新型口腔义齿材料在不影响色泽的情况下具有抗菌性和较
好的生物相容性。
3、本发明所制得新型口腔义齿材料具有更好的耐磨性、耐久抗老化性,使用寿命可延长 5-10 年。
