Removable complete denture
In case of complete tooth loss, using a removable complete denture is a conventional way to replace your missing teeth. It substitutes not just the teeth but the gum too.
It leans on the mucous membrane; the facial muscles, the mucous membrane's surface, the chewing pressure, the vacuum effect and gravity all collectively ensure that it stays in its place. It is made out of a special type of plastic combined with metal parts. The plastic needs to be kept wet, so it doesn't crack and lose its form.
