Abstract The repair of critical‐sized bone defects remains a substantial clinical challenge. While 3D printing bioceramics has emerged as promising strategy to address this issue, conventional often exhibit limited antioxidant and osteogenic activities. To these limitations, novel approach is introduced enhance 3D‐printed hydroxyapatite (HA) scaffolds by incorporating cerium‐containing mesoporous bioactive glass nanoparticles (Ce‐MBGNs) into the digital light processing. nanocomposite bioceramic are systematically optimized varying weight concentrations Ce‐MBGNs (1, 3, 5 wt%). results demonstrate that incorporation significantly enhances mechanical properties, mineralization, capacity, potential HA when compared pure containing Ce‐free MBGNs. In vivo effects wt% (5Ce‐MBGs) group further assessed in rat calvarial defect model. indicate 5Ce‐MBGs effectively facilitate defects. This study highlights integrating with improve scaffold performance. Such an holds promise for developing personalized more effective therapeutic strategies repair, particularly challenging scenarios involving inflammation.

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. This study represents important development GDYO-based photothermal materials field orthopedics expands application biomedical field.

Antimicrobial, Optical, and Mechanical Properties of Saliva-Contaminated Silver–Zeolite Nanoparticle-Incorporated Dental Acrylic Resins

Inorganics, Год журнала: 2024, Номер 12(10), С. 258 - 258

Опубликована: Сен. 25, 2024

Background and Purpose: This study aimed to evaluate the flexural strength, color change antimicrobial effect of silver–zeolite nanoparticles (NPs) in acrylic resin materials. Methods: Fifty-six disc-shaped samples were divided into four groups (n = 7) according concentrations NPs (0%, 2%, 4%, 5%). Discs contaminated with C. albicans S. mutans. The was tested by inoculating discs on Tryptic soy agar (TSA), Sabouraud Dextrose Agar (SDA), broth (TSB), dextrose (SDB). Forty rectangular 65 × 10 2.5 mm specimens also classified 10) NPs. For change, L, a, b values examined a spectrophotometer. A three-point bending test performed using Devotrans device determine bond strength specimens. Scanning electron microscope analysis (SEM/EDX analysis) performed. Results: In this study, increased concentration added discs. our adding 2% more effective against albicans. mutans (<0.001). colonization significantly reduced significant increase observed as nanoparticle percentage ratio (p < 0.001). containing 4% found be clinically acceptable. Conclusions: showed that bacterial fungal is Based its antimicrobial, physical, mechanical properties, we recommend material for optimal results.
