"However, using CT scanning techniques at Pamukkale University, detailed images of the shattered bones that remained of the turtle's jaw were sent to a medical printing company BTech Innovation. With the help of information known about loggerhead turtle anatomy, they were able to reconstruct a replacement jaw that could be fitted to the injured animal's head. They then used 3D printing to create a prosthesis out of medical-grade titanium. ... Professor Enas Altug, the veterinary surgeon who attached the jaw, said that 18 days after the operation the animal appeared to be recovering well and the turtle appeared to be healthy."
