With an aging population, the demand for dental implants is growing. However, a common challenge is insufficient bone volume at implant sites, which could be effectively addressed by guided bone regeneration. Traditional barrier mesh and screws are non-degradable, necessitating a secondary removal surgery, which increases patient discomfort and extra cost.
Based on this, we are developing biodegradable barrier mesh and screws. Our team discovered that the magnesium-gallium alloy, with its superior mechanical properties and consistent degradation, holds vast potential in the dental field.
Our aim is to engineer degradable magnesium-gallium alloy barrier mesh and screw while refining the strategies for guided bone regeneration.
