Researchers at the University of Waterloo have made a breakthrough in the field of medical 3D printing by developing a novel material that can be used to create personalized bone grafts. This innovation has properties similar to bone, so it can revolutionize bone reconstruction procedures by offering personalized solutions.
Traditionally, whenever there’s an injury to bone, the process of reconstruction involves using metal implants or grafts from human donors. But it comes with multiple complications.
Finding a donor bone that perfectly matches the patient’s shape and structure can be difficult. On the other hand, metal implants can lead to post-operative issues like infections or rejection. Existing synthetic grafts may not fully replicate the mechanical properties of natural bone or integrate effectively.
So, this research team, led by Professor Thomas Willett, found the perfect solution for it. They managed to create this new nanocomposite material, that can be 3D printed. It combines a triglyceride-like fat with hydroxyapatite, that makes the material stronger and more durable. Kt creates an ideal surface for bone cells to integrate with the graft, promoting natural regeneration of the damaged bone.
The material can be 3D printed with high precision to match each patient’s unique anatomy, simplifying surgical operations. This customized approach can minimize post-operative complications such as infections or rejection.
The researchers are continuing to refine this material to ensure it can withstand the physical stresses of the human body while being compatible with advanced 3D printers.
