About medicine and a method that is past but work

What is that metal chin, in other incarnation I was a doctor and I had a cousin that was criminal in Russia and when the person is handsome and are intro in the crime sometimes they brake the person right in the face, so the person that is handsome get ugly, probably this is the reason because criminals had the fame of be ugly, in the case of my cousin he has the chin broke and I make for him a metal chin like the medicine of the east Europe, is very expensive you send the draw of it and the factory send it make in a factory that send it back perfect and in no time (very fast), but is very expensive, in the same moment that I close the artifact he could talk, he get heal but stay still using it because he was threaten that his chin would be brake again when it heal so he stay with it for many years I think he only take it off when get out of the crimes.
