#Biocompatibility

Osteointegration:

Silicon nitride promotes bone growth and integration, making it ideal for spinal fusion devices and dental implants. It does not provoke an adverse immune response, facilitating quicker healing and better integration with surrounding bone tissue. Studies have shown that silicon nitride enhances osteoblast activity, promoting the formation of new bone at the implant site, which is critical for long-term implant stability.

Biocompatibility Parameter	Description
Osteoblast Activity	Increased proliferation and differentiation on silicon nitride surfaces compared to other ceramics
Immune Response	Minimal inflammatory response in surrounding tissues
Antimicrobial Properties	Reduction in bacterial adhesion and biofilm formation

Antimicrobial Properties:

The material’s surface can be engineered to exhibit antimicrobial properties, reducing the risk of post-surgical infections. Research indicates that silicon nitride surfaces can disrupt bacterial cell membranes, leading to reduced bacterial colonization and biofilm formation. This property is crucial for maintaining the long-term success of medical implants and reducing the incidence of implant-associated infections.

Pathogen	Reduction Percentage on Si3N4 Surface
Staphylococcus aureus	>90%
Escherichia coli	>85%
Pseudomonas aeruginosa	>80%
