Abstract
Prolonged tooth loss causes a blade-like narrowing of the alveolar bone, severely impairing chewing function and aesthetics and complicating subsequent orthodontic or restorative treatments. Bone morphogenetic protein-2 (BMP-2) can induce bone formation, but may cause many side effects in vivo due to insufficient cell targeting. In this study, we modified BMP-2 with DNA nanostructures to construct BMP-2-loaded hybrid extracellular vesicles, which were combined with a hydrogel sustained-release system. This combination effectively repaired alveolar bone defects and demonstrated the potential to promote bone tissue repair and regeneration.
