Dental bridge, also known as fixed partial denture, is a prosthetic tooth that attaches on one or both sides to teeth prepared with dental crowns. It consists of a pontic (false tooth) to replace the missing tooth and 2 crowns to anchor the pontic in place.The pontic is fused in between 2 crowns, thereby bridging them together. A bridge can restore your appearance and dental function by replacing 1 to 2 missing tooth. It not only fills gaps, but also prevents repositioning of remaining teeth. It can improve your speech and chewing,correct a misaligned bite, and maintain your face shape. The materials used for bridges include gold, porcelain fused to metal, or porcelain alone.
There are 3 main types of dental bridges. Traditional fixed bridge is the most common type of bridge and consists of a pontic fused between 2 porcelain crowns that are anchored on neighboring teeth or implants. Resin-bonded or Maryland-bonded bridges are used when the gap to be filled is in between the front teeth or when the teeth on either side of the missing tooth are h3 and healthy without large fillings. The pontic is fused to metal bands or “wings” that are bonded to the adjacent teeth using cement that is hidden from view. Cantilever bridges are used when there are teeth present on only one side of the space, where the pontic is anchored to one or more adjacent teeth on one side.
