US Patent 8483863 Surgical bone and cartilage shaping on demand with 3D CAD/CAM

In order to effectuate proper construction of prosthetic devices during surgery, a device that will shape the prosthetic device from the patient's own tissue has been contemplated. Although ear surgery requires exacting measurements because of the size that is involved is discussed, many other types of artificial devices can be manufactured during a number of different types of procedures to include orthopedic and dental prosthesis. Many different types of tissues may be used and a computer with associated software will enable a milling machine to manufacture the required prosthetic device at the time of the procedure.
