Bone implants that promote osseointegration and have antimicrobial capabilities are necessary to ensure optimal long-term functionality of implants. In this study, a porous composite osteogenic scaffold was prepared using twin-screw extruder fused deposition modeling three-dimensional (3D) printer. A polydopamine (PDA) coating used load graphdiyne oxide (GDYO) on the surface 3D printed polyetherimide-tricalcium phosphate (PEI-TCP) through π–π double-bond interactions. The resulting P-T-GDYO characterized, its mechanical properties, ability differentiation, light-responsive antibacterial activity were evaluated. When doped with 10 wt% β-TCP, properties remained in range those cancellous bone. terms promoted adhesion differentiation MC3T3-E1 cells, as well effectively promoting endogenous bone regeneration rabbit femoral condyle defects osteogenesis experiments vivo. mouse subcutaneous infection model, after near-infrared light irradiation, showed an rate 90.18 % against Staphylococcus aureus, while maintaining good tissue–organ compatibility.

Advanced Materials Technologies, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 27, 2024

Abstract Polyesters have garnered significant attention in bone tissue engineering (BTE) due to their tunable degradation rates, biocompatibility, and convenient processing. This review focuses on recent advancements challenges the 3D printing of polyester‐based scaffolds for BTE. Various techniques, such as fused deposition modeling (FDM), selective laser sintering (SLS), vat photopolymerization (VP), Wet‐spun additive manufacturing, are explored, emphasizing ability construct with precise architectural control. The main printed polyester limited mechanical properties, lack inherent bioactivity, release acidic byproducts during biodegradation. Strategies enhance scaffold performance, incorporating bioactive ceramics growth factors, discussed, focusing improving osteoconductivity, osteoinductivity, strength. Recent studies integrating these components into techniques optimize porosity biodegradability presented.
