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 (deterioration) process that occurs naturally when teeth are lost or removed. In addition, the clasps that hold the partial denture in place put significant 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.
