Abstract Advanced periodontitis initiates with Porphyromonas gingivalis ( P. ) infection, which subsequently triggers chronic inflammation, immune imbalance, and ultimately causes alveolar bone resorption. Traditional periodontal treatment focuses on the elimination of triggering factors, but tend to ignore improvement inflammatory microenvironment remodeling osteogenic mineralization space. Herein, zinc‐aluminum layered double hydroxide nanosheets (LDHs) loaded icariin (ICA) are encapsulated into a gallic acid (GA)‐modified hydroxybutyl chitosan hydrogel (GA‐HBC), giving rise customized system named GA‐HBC‐LIC, can sequentially actualize antibacterial, anti‐inflammatory, remineralization functions. A neutral chemical‐humoral space is created for osteogenesis via means sequential regulation by smart hydrogel. Concomitantly, appropriate mechanical properties degradation performance provide desirable physical remineralization. In spatiotemporal modulation hydrogel, zinc finger E‐box‐binding homeobox 1 (ZEB1) target released ions (Zn 2+ action promotes macrophage polarization from M1 M2 phenotype, thereby releasing cytokines conducive tissue regeneration. sum, this study highlights critical role inflammation maintenance in regeneration tissues, offering new insights clinical management periodontitis.
