When more than one tooth is missing, there are three common treatment options: the traditional tooth supported bridge, a removable partial denture and an implant supported bridge. In this situation the benefits of implant supported teeth are even more obvious.
A removable prosthesis, such as a partial denture, actually accelerates the bone resorption process, resulting in more rapid bone deterioration. In addition, the clasps which hold the partial denture in place put extreme pressure on the natural teeth they hook onto, loosening them and in many cases, eventually leading to the loss of those teeth. Most patients with partial dentures state that they are uncomfortable and that they rarely wear them.
The advantages of replacing multiple missing teeth with implant supported bridges include the following:
- They look feel and function like natural teeth
- They are much more comfortable and stable than partial dentures
- Natural biting and chewing capacity is restored
- They virtually stop the bone resorption process (deterioration)
- The integrity of the facial structures is maintained
- Adjacent natural teeth are not compromised (ground down into peg shapes or loosened)
