I got a tumor on the lower half of my right jaw. My jaw had to be replaced with metal and some hip bone, but my doctor said the metal is only a teperary fix and i would need another surgery to take bone from my rib to replace the rest of the joint. Its been about a year how long until i need the final surgery? Also my doctor said even after the reconstruction is compleate the artifical joints will eventually wear out how often will i have to have surgery to replace the bone?
