AI Technical Summary

Technical Problem

Existing magnesium alloy barrier membranes have low strength and degrade too quickly, making it impossible for them to exert synergistic antibacterial and osteogenic effects.

Method used

A Mg-Ca/Mg-Cu composite barrier membrane is prepared by controlling the content of Ca and Cu elements. The preparation method involves heating and stacking magnesium alloy plates on rollers to form a barrier membrane with appropriate strength, antibacterial properties, and controllable degradation.

Benefits of technology

It achieves high strength, bone-promoting and antibacterial effects of the barrier membrane, with a moderate degradation rate, meeting the needs of alveolar bone repair and preventing bacterial infection.
