Article Abstract
Guided Tissue Regeneration (GTR) and Guided Bone Regeneration (GBR) are essential surgical techniques in periodontal therapy, employing barrier membranes to prevent soft tissue infiltration and create a conducive environment for bone regeneration. However, the regenerative performance of conventional barrier membranes remains limited due to poor interface management and insufficient biological functionality. Recent developments have introduced the concept of Janus membranes-structures with asymmetric, dual-function surfaces-offering promising solutions to these challenges. While various reviews have addressed barrier membranes for periodontal and bone regeneration, comprehensive reviews specifically focusing on multifunctional Janus membranes are still limited. This review highlights recent advances in Janus membrane design for GTR and GBR applications. It first outlines key structural configurations, followed by an in-depth analysis of fabrication techniques and functional strategies, including osteogenesis promotion, antibacterial activity, and immunomodulation. By summarizing current progress and challenges, this review offers valuable insights into next-generation biomaterial development for periodontal regeneration. Looking forward, Janus membranes represent a compelling avenue for enhancing clinical outcomes in GTR and GBR procedures.

Microbial contamination of absorbable collagen membranes used in guided bone regeneration (GBR) may compromise healing outcomes. This study aimed to investigate whether the minimum inhibitory concentration (MIC) of hydrogen peroxide (HO) can improve the antibacterial effect of indocyanine green (ICG)-mediated antimicrobial photodynamic therapy (PDT) on absorbable collagen membranes while reducing the need for high HO concentrations. A laboratory-based model was developed using Streptococcus sanguinis and Staphylococcus aureus.

Bone defect therapy frequently encounters bacterial infections and chronic inflammation, which impair bone regeneration and threaten implant stability. Iron oxide nanoparticles have attracted attention due to cost-effectiveness, biocompatibility, and metabolic safety. However, iron oxide nanoparticles still struggle to balance low-temperature efficient antibacterial activity, effective immunomodulation, and bone regeneration.

Reconstructing bone defects remains a significant challenge in clinical practice, driving the urgent need for advanced artificial grafts that simultaneously promote vascularization and osteogenesis. Addressing the critical trade-off between achieving high porosity/strength and effective bioactivity at safe ion doses, we incorporated strontium (Sr) into β-tricalcium phosphate (β-TCP) scaffolds with a triply periodic minimal surface (TPMS) structure using digital light processing (DLP)-based three-dimensional (3D) printing. Systematically screening Sr concentrations (0-10 mol%), we identified 10 mol% as optimal, leveraging the synergy between the biomimetic TPMS architecture, providing exceptional mechanical strength (up to 1.

Distraction osteogenesis (DO) is an endogenous bone tissue engineering technique that harnesses the regenerative potential of bone and has been widely applied in limb lengthening, bone defect repair, and craniofacial reconstruction. The DO procedure consists of three distinct phases: the latency phase, the distraction phase, and the consolidation phase, each characterized by unique biological processes. In recent years, increasing attention has been directed toward the role of the immune system during DO.

This study highlights the biomedical relevance of injectable TS (tannic acid-silk fibroin)-Mg/Sr hydrogels in alveolar bone repair, particularly their prospective role as carriers for stem cells from the apical papilla (SCAPs) in tissue regeneration. By utilizing self-assembling silk material, noted for its favorable handling properties, we present a useful approach for single-wall bone defects, such as bone fenestration and fractures in the oral cavity. Furthermore, our findings regarding the involvement of the TRPM7 ion channel indicate a possible regulatory pathway for improving alveolar bone defect repair.
