摘要:

文题释义:
种植体骨结合:是指种植体周围骨组织的改建,在形成骨结合过程的初期,骨细胞促进编织骨和板层骨骨基质的形成,发生新骨与种植体直接接触,而种植体表面之间没有纤维结缔组织长入,直接骨沉积完成骨-种植体界面的结合。种植体与周围骨的骨结合状态直接影响了种植体的稳定性,决定种植体是否成功。
种植体表面药物涂层:是指利用二氧化钛纳米管、壳聚糖、钙磷涂层等作为载体将药物加载于种植体表面,并应用层层自组装技术、仿生共沉积法、物理吸附法等不同方法使之与种植体相结合形成一层具有一定功能的覆盖层,经载体实现药物的有效加载和控释作用,药物从种植体表面局部释放改善种植体周围骨质并增加骨量。

背景:对种植体表面进行药物涂层可显著提高种植体周围骨结合形成,降低种植修复难度。
目的:综述不同药物涂层对种植体骨结合的影响。
方法:由第一作者应用计算机以“implant,osseointegration,surface coatings,systemic drugs,carrier”为英文检索词,以“种植体,骨结合,涂层,系统性药物,载体”为中文检索词,应用计算机检索PubMed、维普、万方、知网数据库中1986年1月至2020年7月已发表的相关文献,并进行筛选、归纳与总结,最终纳入67篇相关文献进行综述。
结果与结论:种植体表面药物涂层经载体局部释放后对种植体骨结合均有一定促进作用,显著提高了种植体与骨组织结合强度及种植体的成功率和最大负荷,尤其减少了骨质疏松症所带来的种植失败发生率。而目前要将这种新型涂层技术大量应用于临床还亟需深入探讨载体材料与药物结合的牢靠性、药物的释放量与释放率难以控制,局部靶组织初始缓释浓度高以及种植体植入机体后的生物相容性、长期稳定性等问题。因此,面对复杂的口腔微环境,以及患者身体状况诸多因素的影响,还有待后期进一步在临床试验中逐一验证,从而发挥药物涂层技术在口腔种植领域方面的积极作用。

Abstract: BACKGROUND: Drug coating on implant surface can effectively enhance dental implant osseointegration and reduce the difficulty of implant restoration.
OBJECTIVE: To review the effects of different drug coating on implant surface on osseointegration.  
METHODS: The first author searched PubMed, VIP, Wanfang and CNKI databases for relevant articles published from January 1986 to July 2020. The search terms were “implant, osseointegration, surface coatings, systemic drugs, carrier” in English and Chinese, respectively. Finally, 67 articles were included in result analysis after screening and summarizing.
RESULTS AND CONCLUSION: Drug coating on the surface of dental implants can promote the local release of bone binding of dental implants through the carrier, and significantly enhance osseointegration intensity and success rate and maximum load of implant, especially reducing the risk of implantation failures rates by osteoporosis. However, we need to solve some problems before this new coating technical is applied to the clinic: the reliability of the combination of carrier materials and drugs, drug release rate and release amount difficult to control, high initial sustained release concentration of local target tissue and difficult to maintain long-term stability and biocompatibility after implantation. Therefore, in the face of the complex oral microenvironment, as well as the influence of many factors of the patient’s physical condition, it needs to be further verified in clinical trials in the later stage, so as to play a positive role of drug coating technology in the field of oral implantation.
