Most people know about dental implants and crowns, but few realize how important the abutment is. This small piece connects the implant to the crown and shapes the gums for a natural-looking smile.
How Abutments Work
An abutment attaches directly to the dental implant and supports the crown, bridge, or denture. Dentists typically use titanium or zirconia because these materials are strong, durable, and look natural. The abutment also guides the gums as they heal, ensuring the crown blends seamlessly with your other teeth.
Healing vs. Final Abutments
After implant surgery, your dentist may place a healing abutment. It protects the implant opening and helps gums heal properly. Unlike the final abutment, it does not hold a crown but prepares the site for the restoration.
Custom Abutments
For visible areas of the smile, dentists may create custom abutments. These match your mouth’s anatomy and help the crown emerge naturally from the gums, improving both comfort and aesthetics.
Attaching the Crown
Dentists attach crowns to abutments in two main ways:
- Cement-retained crowns: Bonded to the abutment for a smooth appearance
- Screw-retained crowns: Secured with a screw, allowing easy removal if adjustments are needed
Each method has pros and cons. Cemented crowns can irritate gums if excess cement remains, while screw-retained crowns may have a small access hole. Your dentist chooses the best option for your situation.
Choosing the Right Abutment
Abutments come in various shapes and sizes. Your dentist evaluates your bite, gum tissue, and implant location to select the one that provides strength, comfort, and a natural look. Choosing the right abutment ensures your implant looks and functions like a real tooth.
