Today, although they can not produce a single artificial organ, they create 3D topographic map of the region to be operated with the help of EMARs, which are taken by physicians at the beginning of the operation, and they can be printed with the help of 3D printers by making them concrete objects. see what they will encounter during the operation and make the road map more comfortable, that is, they have been rehabilitating a kind operation. As can be guessed, having such a practice before the operation has a great effect on the success of the operation. In the same way, the part to be exposed to maxilofacial operation can be scanned and formed in 3D shape. Surgeons can determine how to trace a path map by performing a preliminary study on the solid model of the corresponding region in the hand.
