好的牙·讯|阿曼牙科学院(Oman Dental College)研究团队近日宣布成功开发出一种创新型牙科填充材料,该材料通过将阿曼波特兰硅酸钙与碳纳米板复合,实现机械强度与生物组织相容性的双重突破。

据阿曼通讯社(ONA)报道,该项目历时五年,现已进入二期人体试验阶段,并获得阿曼苏丹国专利及国际注册认证。

研究团队成员Malak Khalifa Al Harthy指出,传统的牙科填充材料在强度与生物相容性之间存在难以兼顾的问题。为解决这一难题,团队通过将本土产波特兰硅酸钙与石墨烯片结合,最终研制出一种机械效能显著提升且具备优异生物相容性的新型复合材料。

此项研究成果的动物实验阶段与阿曼皇家骑警指挥部(Mounted Police Command)的合作验证了材料的安全性,目前二期人体试验的初步数据已显现积极效果。

据介绍,该复合材料展现出多项突破性特征。碳纳米板的整合不仅增强了材料的机械性能,其与生理体液中的钙离子反应形成的协同效应,为周围牙体组织重建细胞创造了理想的再生环境。此外,纳米板特有的体积膨胀效应使得材料具备密封性,特别适用于需要严格防渗的复杂牙科场景。

据悉,该材料已进入市场化筹备阶段,预计将率先在阿曼本土应用,后续逐步推广至全球市场。
