摘要: 引导骨再生(guided bone regeneration, GBR)是最常见的骨增量手术,而其效果受到生物屏障膜的材料特性所影响。鉴于现有的生物屏障膜无法同时满足生物相容性好、力学强度高、降解可控、生物活性佳且易操作性等临床需求,亟待研发一种新型生物屏障膜材料。可降解金属(biodegradable metals, BMs)是指一种预期在体内降解的金属。其中,锌基BMs因其优异的材料特性,有望成为新一代生物屏障膜材料。然而,锌基生物屏障膜仍处于基础研究阶段。在此,笔者结合团队前期的研究工作,基于今后的临床应用考虑,系统地阐析锌基生物屏障膜在生物相容性、力学性能、降解性能和生物活性四个方面的研究进展及不足,为促进其临床转化提供科学依据。

Abstract: Guided Bone Regeneration (GBR) is the most common bone augmentation procedure in implant dentistry, and the effect of bone augmentation is determined by the material properties of the biological barrier membranes. However, are current biological barrier membranes are insufficient for all clinical requirements, including excellent biocompatibility, high mechanical properties, controllable degradation behavior, superior bioactivity, and easy clinical management. It is required to develop and investigate a novel material for the biological barrier membrane. Biodegradable metals (BMs) refer to metals that are intended to degrade in vivo. Among them, zinc(Zn)-based BMs are regarded as a novel generation of biological barrier membrane materials due to their excellent material properties. Nevertheless, Zn-based biological barrier membranes have been still in the stage of research and development. Based on our previous research studies and considering the future clinical applications, this paper systematically reviewed the research status and drawbacks of Zn-based biological barrier membranes in terms of four aspects: biocompatibility, mechanical properties, biodegradability, and bioactivity, providing scientific evidence to promote its clinical transformation.
