Bridges: A bridge replaces missing teeth by placing crowns on the teeth next to the space and attaching a fake tooth to both of the crowns. Bridges are made from gold, porcelain fused to gold, all porcelain, or zirconium. Bridges can only replace about two to three missing teeth in a row, depending on the location. Since bridges are cemented in place, they are considered a "fixed, or permanent denture."
An overdenture is a removable dental prosthesis that covers and rests on one or more remaining tooth roots. A removable partial denture is a dental prosthesis that replaces some teeth and is built around existing natural teeth. Both the overdenture and the removable partial denture may be connected to the remaining tooth roots or remaining natural teeth with anchors made of metal or plastic. These connections improve stability and the retention of both prostheses.
