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.
