After my left lower jaw was removed, mouth reconstructed using my leg bone, etc, a year ago I am experiencing my first "appliance" or teeth built on a cobalt chromium base. How do you keep it in place? I have a frame that goes over back right side teeth around the left side and sits on reconstructed gum. There is nothing on left side of gum to anchor the device. How do you hokd it in place when you talk, chew food, drink?
