A fixed bridge is a dental restoration offered by the cosmetic dentist in Scottsdale, AZ. It replaces one or more missing teeth by spanning the gap between adjacent teeth. It is a non-removable appliance that is cemented or bonded to the surrounding teeth. Let’s explore some common facts about fixed bridges.
What are the benefits of fixed bridges?
There are several types of fixed bridges, including:
Traditional fixed bridge: Made of ceramic or porcelain fused to metal (PFM), this is the most common type of fixed bridge.
All-ceramic fixed bridge: Made of ceramic or porcelain only, this type of bridge is more aesthetically pleasing and suitable for front teeth.
Cantilever fixed bridge: Used when only one adjacent tooth is available, this type of bridge has a pontic that is supported by a single abutment tooth.
Resin-bonded fixed bridge: A metal or ceramic wing is bonded to the back of adjacent teeth, making it a more conservative option.
Maryland bonded bridge: A type of resin-bonded bridge that uses a metal or ceramic framework with wings that are bonded to the back of adjacent teeth.
Implant-supported fixed bridge: Supported by dental implants instead of natural teeth, this type of bridge is suitable for patients with multiple missing teeth.
Hybrid fixed bridge: A combination of a fixed bridge and a removable partial denture, this type of bridge is suitable for patients with multiple missing teeth.
Zirconia fixed bridge: Made of zirconia ceramic, this type of bridge is strong and aesthetically pleasing.
E-max fixed bridge: Made of lithium disilicate ceramic, this type of bridge is strong and aesthetically pleasing.
3/4 crown fixed bridge: A type of bridge that covers only 3/4 of the abutment tooth, leaving some natural tooth structure visible.

The components of a fixed bridge include:
Pontic: The artificial tooth that replaces the missing tooth.
Abutments: The teeth on either side of the gap that support the bridge.
