Fixed bridges are a type of dental restoration used to replace one or more missing teeth. They are called “fixed” because they are permanently attached to the surrounding teeth, unlike removable dentures. The cosmetic dentist in Duncanville, TX, offers premium-quality bridges for teeth replacement. Let’s explore them further.
What is a fixed bridge?
A fixed bridge is a non-removable dental appliance used to replace one or more missing teeth. It consists of artificial teeth, called pontics, which are anchored to the surrounding natural teeth, known as abutment teeth, via crowns. This restoration is custom-made to match the color, shape, and size of the surrounding teeth, providing a natural-looking smile. Fixed bridges can be made from various materials, including ceramic, porcelain, metal, or composite resin.
What are the parts of a fixed bridge?
A fixed bridge typically consists of the following parts:
- Abutment teeth: The healthy teeth on either side of the gap, serve as anchors for the bridge.
- Abutment crowns: The crowns that cover the abutment teeth, providing a surface for the bridge to attach to.
- Pontics: The artificial teeth that replace the missing teeth, suspended between the abutment crowns.
- Connector: The part of the bridge that connects the pontics to the abutment crowns.
- Framework: The underlying structure of the bridge, which supports the pontics and connector.
- Retainer: The part of the bridge that attaches to the abutment tooth, holding the bridge in place.
- Occlusal surface: The chewing surface of the pontics.
- Lingual surface: The surface of the pontics facing the tongue.
- Mesial surface: The surface of the pontics facing the adjacent tooth.
- Distal surface: The surface of the pontics facing the opposite direction.
