Abstract: BACKGROUND: 3D-printed biomimetic bioceramic scaffolds, characterized by personalized design, superior biocompatibility, and osteogenic potential, represent an ideal solution for jaw defect repair.
OBJECTIVE: To systematically review recent advances in 3D-printed bioceramic scaffolds with biomimetic structures for jaw repair.
METHODS: Literature searches were conducted on PubMed and CNKI from database inception to 2025 using Chinese and English search terms “3D printing, scaffold, bionic, biomimetic, ceramic, maxillofacial repair, jaw repair.” Sixty-eight relevant articles were included for critical analysis.
RESULTS AND CONCLUSION: Jaw defect repair requires balancing anatomical restoration and functional recovery. 3D-printed biomimetic bioceramic scaffolds, through designs such as gradient porosity and mechanical adaptation, precisely match defect morphology, outperforming traditional grafts (e.g., autologous bone) in bioactivity and osteoconductivity. Osteomimetic structures (e.g., trabecular bone simulation) and bioinspired hierarchical architectures enhance osseointegration efficiency. The current research on 3D-printed bioceramic scaffolds in jaw repair is still in its infancy. While initial studies confirm mechanical stability and biosafety, long-term degradation kinetics, immune responses, and clinical scalability require further investigation.
