 Guided bone regeneration, GBR, is a common dental procedure used to restore lost or damaged teeth. Traditionally, membranes have been used to protect the bone from soft tissues while it heals, but these membranes can cause complications such as inflammation and infection. Magnesium barrier membranes have been developed to address these issues, and they have shown promise in clinical trials. This paper reviews the literature on magnesium barrier membranes and summarizes their use in two case studies. The results suggest that magnesium barrier membranes are effective at preventing soft tissue contamination and reducing inflammation, and they are fully resorbed by the body without any adverse effects. These findings support the use of magnesium barrier membranes in GBR procedures. This article was authored by Marco Blazkowicz, Ivano-Butoric Propic, Dorothea Blazkowicz, and others.
