What is a anchor tooth?

In dentistry, an anchor tooth refers to a tooth that is used as a stable support or attachment point for a dental prosthesis, such as a bridge or a partial denture. It is also sometimes called an abutment tooth.

Anchor teeth are typically healthy and strong teeth that have enough bone support to withstand the forces exerted by the prosthesis. They are strategically selected based on their location, strength, and condition to provide stability and longevity to the dental restoration.

When creating a bridge, for example, the anchor teeth are prepared to receive crowns or other types of restorations that will hold the artificial tooth (pontic) in place. The pontic is then attached to the crowns on the anchor teeth, essentially bridging the gap created by the missing tooth.

Similarly, in the case of a partial denture, anchor teeth may be used to support and stabilize the denture. Clasps or other attachment mechanisms are used to connect the partial denture to the anchor teeth, ensuring a secure fit and preventing the denture from moving around in the mouth.

The selection of appropriate anchor teeth is crucial for the success and durability of the dental prosthesis. Factors such as the condition of the teeth, their location, and the amount of force they can withstand are carefully considered during treatment planning.
