I'm 42 with the teeth of a 70 year old. I have 6 crowns already all of which are damaged and need to be replaced. Other crowns are needed. The procedure would take up to 9 months, involve many many dentist visits, result in crowns on ALL teeth, realign my jaw, and lots more. I don't really understand it.
Gnathological reconstruction IS a proven and valid treatment for many situations.
It is used to correct a person's bite, or occlusion. When you grind your teeth over the course of many years, your teeth become shorter and shorter. This can create stress on your jaws, muscles, and joints. Now that it has become necessary to replace many of your crowns, a decision needs to be made about what height to make them. If we design your crowns at their 'appropriate' height, then you will need full-mouth gnathological reconstruction to equilibrate the rest of your bite.
