Peri-implantitis, an inflammatory condition affecting the soft and hard tissues around dental implants, poses significant treatment challenges. The complexity of peri-implantitis treatment lies in achieving thorough decontamination while promoting effective bone regeneration, necessitating advanced techniques and materials to restore implant stability and ensure optimal patient outcomes. The technological advancements are transforming the approach to peri-implantitis, making treatments more effective, less invasive, and more tailored to individual patient needs, ultimately improving the prognosis for affected implants. In particular, the demand for new materials in dentistry is driven by the need to overcome existing challenges and improve overall success of dental procedures. This has led to the introduction of novel biomaterials to enhance bone regeneration and stability around implants, promoting better long-term outcomes. The fully resorbable magnesium NOVAMAg^® membrane has emerged as a groundbreaking solution in GBR, particularly for challenging applications such as peri-implantitis and socket dehiscence.
