Textured Surface Impacts the Fusion Process
Macro roughness promotes immediate mechanical fixation and decreased risk of migration once the device is implanted. Micro and nano textures interface with the patient's cells to promote natural production of the osteogenic and angiogenic factors necessary for bone growth and fusion.1 All three levels of roughened features work together to allow the implant to be an active participant in the fusion process.
