Once all the teeth are lost, one treatment choice is to place a denture. The thing to remember is that as teeth are lost, some bone is also lost. It is very hard to make a well-fitting denture if too much supporting bone is lost. This can make wearing a denture very difficult. Today the fit of a denture can be improved dramatically by first placing a few dental implants. The denture then sits on these implants to improve fit and function.
