Magnesium-Based Resorbable Biomaterials: Biological Effects to Clinical Use

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Orthopedic Surgery

Background:

• Magnesium (Mg) is a promising biomaterial for biomedical applications, particularly in bone fixation and regeneration.
• Mg-based materials offer advantages over traditional implants like polymers and permanent metals, addressing issues like stress shielding and inflammation.

Purpose of the Study:

• To review the current knowledge on Mg-based biomaterials, focusing on their biological effects and clinical potential.
• To emphasize applications in oral and craniomaxillofacial bone regeneration.
• To discuss limitations and future directions for Mg biomaterials.

Main Methods:

• Literature review of current research on Mg-based biomaterials.
• Analysis of clinical trial data and regulatory approvals.
• Exploration of Mg's biological and immunomodulatory roles in bone regeneration.

Main Results:

• Mg-based biomaterials exhibit biocompatibility, biodegradability, and suitable mechanical properties.
• Mg demonstrates pro-osteogenic, anti-osteoclastic, and anti-inflammatory effects, enhancing bone regeneration.
• Clinical applications in guided bone regeneration show potential, though regulatory hurdles exist.

Conclusions:

• Mg-based biomaterials are viable alternatives for bone fixation and regeneration, especially in oral and maxillofacial surgery.
• Further research into Mg's degradation and biological activity is needed to overcome clinical limitations.
• Innovative Mg delivery systems could unlock the full potential of these biomaterials in regenerative therapies.
