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 ...

Defect chemistry and electrical properties of sodium bismuth titanate perovskite

Journal of Materials Chemistry A, 2018
The ferroelectric perovskite Na0.5Bi0.5TiO3, NBT, can exhibit three types of electrical behaviour, i.e. oxide-ion conduction (type I), mixed ionic–electronic conduction (type II) and insulating/dielectric (type III) based on various defect mechanisms. Here we review how to tune the electrical properties of NBT via several mechanisms, including A-site ...
