Crown refers to the restoration of teeth where a fabricated crown is used to cap or completely cover a tooth.
An abutment crown is a component used in dental restorations, specifically in the context of dental implants. When a patient undergoes a dental implant procedure, a titanium implant is surgically placed into the jawbone to serve as an artificial tooth root. After a period of healing, an abutment is attached to the implant.

What is an abutment crown?
An abutment crown is a dental restoration that is placed on a dental abutment, which is a natural tooth or a dental implant. It serves as the supportive structure for a dental prosthesis, such as a bridge or a single-tooth implant crown.
When is an abutment crown used?

How does an abutment crown differ from a regular dental crown?
An abutment crown is similar to a regular dental crown in terms of its appearance and function. However, the key difference is that an abutment crown is specifically designed to act as a support or attachment for a dental prosthesis, providing stability and a secure foundation.
What materials are used for abutment crowns?
Abutment crowns can be made from various materials, including metal alloys, porcelain-fused-to-metal (PFM), zirconia, or all-ceramic materials. The choice of material depends on factors such as aesthetics, strength, and the location of the abutment.

Is the placement of an abutment crown a painful procedure?
The placement of an abutment crown is typically done under local anesthesia to ensure that the patient is comfortable and experiences minimal discomfort during the procedure.
How long do abutment crowns last?
The lifespan of abutment crowns can vary depending on factors such as oral hygiene, biting forces, and the materials used. With proper care and regular dental check-ups, abutment crowns can last for many years.
Can abutment crowns be replaced if needed?
Yes, if an abutment crown becomes damaged or if there are changes in the surrounding dental structures, it can be replaced. The process involves removing the existing crown and fabricating a new one to fit the abutment.
Are abutment crowns covered by dental insurance?
The coverage for abutment crowns by dental insurance can vary depending on the specdentific terms of the insurance plan. It’s advisable to check with the insurance provider for details on coverage.
