Alveolar Bone Regeneration: Smart Biomaterials and Physical Stimulation

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 4, April 2026.
ABSTRACT Large‐area bone loss from disease, trauma, or congenital defects requires surgical procedures and bone grafting. Alveolar bone loss from severe periodontal disease and non‐unions often demands immediate grafting. Treating large alveolar bone defects using grafts and substitutes is challenging due to the complex oral environment, infection ...
