Dental Abutment
When people typically think about dental implants, they usually picture the implant itself and the crown that restores the missing tooth. However, there’s a key component in between that plays an essential role in the success of the implant: the dental abutment. While it may not get as much attention, the abutment is a crucial part of the implant system. If you’re considering dental implants and want to understand how they work, it’s important to know what a dental abutment is and why it matters. Read on to learn more.
What Is a Dental Abutment?
A dental abutment is a small piece that connects the dental implant to the crown, bridge, or denture that will complete your tooth restoration. It is typically made from titanium or zirconia. These materials are chosen for their strength and compatibility with the body. The abutment acts as a sturdy link between the implant post, which sits in the jawbone, and the visible tooth restoration above the gumline.
Besides serving as a connector, the abutment also helps shape the gum tissue around the crown or bridge. This shaping is important for both the health of the gums and the natural appearance of the final restoration.
Types of Abutments
Not all abutments are the same. Your dentist will choose the type of abutment that best suits your needs. One common type is the healing abutment, which is placed after the implant surgery. Its main job is to cover the opening of the implant and guide the gum tissue to heal properly around the area. While it is temporary and not part of the final restoration, it plays a crucial role in preparing the site.
In many cases, your dentist may also recommend a custom-made abutment. This is designed to fit your specific anatomy, ensuring that the final crown blends seamlessly with your natural teeth. Custom abutments are especially useful for implants placed in highly visible areas, such as the front of the mouth.
Attachment Methods
There are two main ways that the crown or bridge is attached to the abutment. These methods are cementing or screwing. Each method has its advantages and drawbacks. A screw-retained crown can be removed more easily if repairs are needed, but it may have a small screw hole that affects the crown’s strength or appearance. On the other hand, cementing the crown provides a smooth, natural look, but requires careful placement to avoid excess cement, which can irritate the gums.
Why the Abutment Matters
The abutment may seem like a small part of the implant system, but its role is critical. It ensures that the dental restoration is secure, functional, and natural-looking. From guiding proper gum healing to providing a stable base for your new tooth, the abutment is a key piece of the overall success of a dental implant.
