When several teeth are missing in a particular area, an implant bridge can be used. The first step is to place at least two implants in the desired area to anchor the bridge. The bridge, comprised of three or more teeth, is then attached to the implants in order to replace the missing teeth. These bridges are typically made from a white porcelain material and anchored to the implants with titanium screws. These bridges can be removed by your doctor if absolutely necessary, however they are typically left in place indefinitely. Implant bridges can serve as a very natural way to replace missing teeth, and the patient would likely find them indistinguishable from natural teeth.
