CHENGDU, China: Though modern treatments for periodontal disease can offer some solutions for dental tissue restoration, they often fail to reproduce the original complex anatomical structure of tissue. 3D bioprinting has revolutionised care by offering precision in tissue regeneration. A team in China has published a review of the currently available 3D-printing methods for collagen-based biomaterials and their application for regeneration of oral tissue such as pulpal nerve and blood vessels, cartilage and periodontal tissue.
