NUS Researchers Use AI and 3D Bioprinting for Personalized Dental Grafts

The National University of Singapore (NUS) has developed a novel approach that combines 3D bioprinting with artificial intelligence (AI) to create personalized gingival tissue grafts, announced in a press release. This innovative method aims to improve dental treatments by offering a more customizable and less invasive alternative to traditional grafting techniques.

Led by Assistant Professor Gopu Sriram, the NUS team has addressed key challenges in dental procedures, such as repairing gum defects from periodontal disease or dental implants. The AI-enhanced bioprinting process optimizes parameters like extrusion pressure and print speed, significantly reducing the time and resources required for graft fabrication.

The bioprinted gum tissue grafts maintain high cell viability and structural integrity, closely resembling natural gum tissue. This advancement not only reduces patient discomfort but also minimizes the risk of complications during recovery. The research, supported by grants from the National Additive Manufacturing Innovation Cluster and National University Health System, was published in the journal Advanced Healthcare Materials.
