摘要: Abstract Magnesium has been recently introduced as a novel biodegradable material for bone healing. However, the fast degradation of this results in release hydrogen which limits its clinical applications. In view that, present study, we attempt to overcome drawback using bredigite (Ca7MgSi4O16) coating. our previous work, have coated AZ91 magnesium implants with through combination anodic spark deposition (ASD) and electrophoretic (EPD) techniques. As continuation that paper, focused on vivo examination bredigite/ASD compared plain ASD uncoated substrates. The animal test greater trochanter rabbits indicated improved regeneration less inflammation upon employing implants. addition, an enhancement biodegradation was observed by reduction ion released blood plasma. summary, surface treatment promotes their healing capabilities future
