Which Component Of A Fixed Bridge Anchors To Existing Teeth
When it comes to dental bridges, there are two main types: removable and fixed. Removable bridges can be taken out and cleaned, while fixed bridges are permanent and require special care. Fixed bridges are anchored to existing teeth, but which component of the bridge actually anchors to the teeth?
Abutment Teeth
The part of the bridge that anchors to existing teeth is called the abutment. The abutment teeth are the teeth on either side of the gap where the missing tooth or teeth used to be. These teeth are prepared by removing some of the enamel so that the bridge can be cemented onto them.
The abutment teeth are crucial to the success of the bridge, as they provide the support needed to hold the bridge in place. Without strong and healthy abutment teeth, the bridge may not be able to stay in place and could shift or come loose.
Pontic
The other component of a fixed bridge is called the pontic. This is the part of the bridge that replaces the missing tooth or teeth. The pontic is made of porcelain or other materials that are designed to look and function like natural teeth.
The pontic is attached to the abutment teeth by means of crowns or other attachments. These attachments are designed to hold the pontic securely in place and prevent it from shifting or coming loose.
Crowns
Crowns are an important part of fixed bridges, as they are used to anchor the pontic to the abutment teeth. Crowns are custom-made caps that are placed over the existing teeth to provide a secure base for the bridge.
Before the crowns can be placed, the abutment teeth must be prepared by removing some of the enamel. This allows the crowns to fit securely over the teeth and provide the necessary support for the bridge.
Implants
In some cases, dental implants may be used to anchor the bridge instead of abutment teeth. Implants are artificial tooth roots that are placed into the jawbone and allowed to fuse with the bone over time.
Once the implants are securely in place, the bridge can be attached to them using special attachments. This provides a secure and stable base for the bridge, and eliminates the need to prepare healthy teeth for crowns.
Conclusion
When it comes to fixed bridges, the abutment teeth are the component that anchors the bridge to the existing teeth. Crowns or other attachments are used to secure the bridge to the abutment teeth, while the pontic replaces the missing tooth or teeth.
Implants may also be used to anchor the bridge, providing a secure and stable base without the need for healthy teeth to be prepared for crowns. Proper care and maintenance of the abutment teeth and the bridge itself is essential to ensure the success and longevity of the fixed bridge.
