摘要/Abstract

摘要：

成骨细胞是骨形成的主要功能细胞,它在种植体上的黏附是成骨细胞行使生物学功能的前提。然而临床上常见的种植体大多属于惰性金属,存在生物活性差、缺乏骨诱导等问题,不利于成骨细胞黏附,因此常需要对其进行表面改性。纳米形貌是近年来研究的热点,它具体是指种植体表面单元和尺寸为 1~100 nm的拓扑结构,其在结构上与细胞外基质相似,有着亲水性佳、生物相容性好及抗菌等多方面优势,但并非所有的纳米形貌都有利于成骨细胞黏附。本文从成骨细胞在纳米表面的黏附过程、常见纳米表面结构及其表面修饰三个方面进行综述,以期为种植体表面纳米改性和临床应用提供参考。

Abstract:

Osteoblasts are the main functional cells of bone formation, and their adhesion to the implants is the premise of biological function. However, most of the common clinical implants are inert metals, which have some problems such as poor biological activity and lack of bone induction, which are not conducive to osteoblast adhesion, so it is often necessary to modify their surface. Nano-morphology is a hot topic in recent years, which refers to the topological structure of implant surface unit and size 1-100 nm, similar to extracellular matrix in structure, with many advantages such as enhanced hydrophilicity, superior biocompatibility and antibacterial properties. However, not all nano-morphologies are conducive to osteoblast adhesion. This paper reviews the adhesion process, common nano-surface structure and surface modification of osteoblasts on nano-surface, in order to provide reference for implant surface nano-modification and clinical application.

Key words: dental implant, nanostructure, surface morphology, osteoblast, cell adhesion
