The inherent limitations of smooth titanium abutments—particularly inadequate soft tissue sealing that predisposes implants to infection and inflammation—underscore the need for surface modifications. This review synthesizes evidence on magnesium-containing coatings as a bioactive solution to enhance peri-implant soft tissue healing. Through 1) modifying the surface properties of the implant abutment to promote better cell adhesion and proliferation; 2) releasing Mg 2+ to promote fibroblast migration, collagen synthesis, and angiogenesis; and 3) exerting antimicrobial effects and regulating inflammatory responses, these coatings establish a microenvironment conducive to robust tissue integration. This helps prevent peri-implant infections and inflammation, strengthens soft tissue attachment, and improves the long-term stability of dental implants, providing a new direction for the development of biomedical materials.
