What was the reason, if you don't mind telling us?
I had an overbite, so the dentists removed eight teeth 4 each from upper and lower, 4 each from right and left, to reduce the number to fit into my jaws, and I wore braces to pull my upper teeth back to fill the empty spaces, and after a few years and the upper teeth moving back as far as they could, they broke and reset my lower jaw to it would extend farther forward and the lower front teeth would reach the upper front teeth.
The way they broke my lower jaw wasn't perpendicular but very slanting so there was a lot of overlap between the back and the front sections, and they moved the front section forward a little and then bolted the jaw back together so the bone would grow back together at the new length.
I imagine there was some sort of medical device to break the jaw the proper way. I wonder what the patent office examiner thought when he read an application for a jaw breaking device,. Did he think at first that it was supposed to be a torture device?
