文题释义:
生物活性玻璃:是一类以硅酸盐为主要基质的人工复合材料,因其能在材料表面诱导特定生理反应,使组织与之结合,被称为生物活性玻璃。其已被广泛运用在骨科以及口腔科临床疾病治疗上,口腔疾病方面主要应用于填充拔牙窝、牙周病导致的骨缺损、牙本质过敏等;骨科方面只要应用于非承重部位骨缺损修复、骨折的愈合、脊柱融合等。
纳米生物活性玻璃:是一种主要通过溶胶-凝胶法制备出的纳米级生物活性材料,由大量纳米级球形生物活性玻璃颗粒堆积而成,颗粒的直径通常为2-50 nm,颗粒堆积形成大量的纳米孔隙,除了具有传统生物活性玻璃的性能,还具有高比表面积、高生物活性、高降解性的特点,近年来成为组织再生领域的研究热点之一。
 
 
背景:纳米生物活性玻璃的发展为口腔组织再生修复提供了更多的选择,是现今口腔组织再生材料的研究热点。
目的:通过对国内外相关论文的总结讨论,综述纳米生物活性玻璃的口腔组织再生领域的研究进展。
方法:以“生物玻璃,纳米”为中文检索词,以“bioactive glass,nanostructure,mesoporous”为英文检索词,应用计算机检索中国期刊全文数据库CNKI和PubMed数据库中2000年1月至2017年3月有关纳米生物活性玻璃应用于口腔组织方面的文章。

结果与结论:与传统生物活性玻璃相比,纳米生物活性玻璃材料具有更优秀的生物活性、降解性能、载药性、抗菌性等。为进一步提高纳米生物活性玻璃材料的理化和生物性能,可在材料中添加镁、锌、锶、铜、银等元素。目前制备纳米生物活性玻璃材料的方法有溶胶-凝胶法、模板合成法、微乳液法、火焰喷雾法、3D打印等,其中的3D打印技术可能为今后制备纳米生物活性玻璃材料的较理想方法。纳米生物活性玻璃在口腔组织再生中的应用基本停留在体外和动物实验阶段,已证明其可促进颌骨和牙体硬组织的再生,但尚未见临床报道,所以未来依然需要更多长期详细的研究,使各类纳米生物活性玻璃材料能够在临床上安全有效的使用。

Abstract:

BACKGROUND: The development of nanostructured bioactive glasses that are a popular material for oral tissue regeneration provides a better choice for dental tissue regeneration.

OBJECTIVE: To summarize the research progress of nanostructured bioactive glasses in the field of oral tissue regeneration by reviewing relevant domestic and foreign literatures.
METHODS: With the key words of “bioactive glass, nanostructure, mesoporous” in Chinese and English, we performed a computer-based search in CNKI and PubMed database for relevant articles published from January 2000 to March 2017.

RESULTS AND CONCLUSION: Nanostructured bioactive glasses have better bioactivity, degradation, drug-loading capability and antibacterial property compared with traditional bioactive glasses. Addition of various ions, such as magnesium, zinc, strontium, copper, silver, can further improve the physiochemical and biological properties of nanostructured bioactive glasses. A variety of methods, including sol-gel, template-directed synthesis, microemulsion, flame spray and 3D printing, have been performed to fabricate nanostructured bioactive glasses, among which, 3D printing may be an ideal method in the future. Studies on nanostructured bioactive glasses are still at in vitro and animal experimental levels, though they have been confirmed to be used in regeneration of maxillofacial bone and tooth. Considering that there are still no relevant clinical reports, further investigations are needed to verify its clinical effects and safety.
