Recent Advances in the Development of Magnesium-Based Alloy Guided Bone Regeneration (GBR) Membrane

In dental implantology, the guided bone regeneration (GBR) membrane plays an active role in increasing alveolar bone volume. However, there are some drawbacks to the current commercial membranes, such as non-degradability for non-absorbable membranes and low mechanical strength for absorbable membranes. Recently, magnesium (Mg) alloys have been proposed as potential barrier membrane candidates. As a result, the purpose of this research is to assess the feasibility of Mg alloys as GBR membranes in terms of physicochemical properties and biological performance. Mg alloys were identified as potential membrane materials due to their adjustable degradation, adequate mechanical support, sound osteogenic property, good bacteriostatic activity, and favorable wound-healing ability. Nonetheless, rapid degradation and stress corrosion cracking (SCC)/corrosion fatigue (CF) are major concerns for the use of Mg-based membranes, which can be mitigated through alloying, heat treatment, thermomechanical deformation, and other methods. Finally, the prospects for the design and manufacture of Mg-based membranes in the future were put forth.
