Robotic-assisted 3D printing for bone defect reconstruction
Reconstruction of bone defects has always been a challenging task for the surgeons over the years. The expected goals of this kind of reconstructive surgery are not only to restore bone function but also to maintain the appearance of the human body. One of the methods to repair the defected bone is …
