Have you ever wondered what a dental implant is? Maybe you’ve had a tooth removed and your dentist has offered implants as a replacement option. In this blog post, I will focus on discussing the components that make up an implant restoration.
Let’s start by explaining what makes up a dental implant. Wikipedia defines dental implants this way:
A dental implant… is a surgical component that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, (or) denture.
In most cases, the dental implant therapy involves three components:
First is the implant itself. This is the part that, as Wikipedia says, interfaces with the bone of the patient’s jaw. The dental implants we use today are made of titanium. Through a process called osseointegration, the implant will form an intimate bond with the patient’s bone, which anchors it in place. Most times, the implants’ shapes and sizes are designed to mimic the root of the tooth it is replacing. Implants typically have a tapered, threaded design which allows for accurate and stable placement. Dental implants also have a special coating or treatment on their surfaces that help them integrate with the jaw bone.
The second part of the dental implant therapy is the implant abutment. This is the intermediary part that joins the crown, bridge or denture to the implant. The abutment interfaces with the implant with very precise machined surfaces and is often held in place with a screw through its center. The screw is then tightened to a specific setting using a special torque wrench. The implant abutment serves as the transition piece from the implant through the gum tissue to the final restoration.
The third part is the crown or bridge. This is the part that completes the implant therapy. It resembles the tooth in form and function. It is most times an individual crown or bridge and is held to the implant abutment by cement. Once the cement is cured, the restoration (crown or bridge) is then ready for normal use. Most times these components are fixed, or are anchored, permanently in a patient’s mouth. The crown or bridge will not need to be removed.
Each component of a dental implant also typically carries its own fee, so you may find that the fee breakdown from your dentist will list the fee for each of these parts separately.
