How it works

A dental implant has three main parts: the implant body in the bone, the abutment, and the crown on top. This drawing cuts through the jaw so the screw inside the abutment shows too, with a natural tooth beside it.

Implant and tooth side by side

The implant is on the left and a natural tooth on the right. The implant body sits in the bone where the tooth's root would be, the abutment passes through the gum, and the crown is the part you see.

  • On this drawing the screw is shown inside the abutment, as if the post were cut in half.

Questions and answers

What are the three parts of a dental implant?

The implant body, a threaded post set into the jawbone; the abutment, which joins it to the tooth and passes through the gum; and the crown, the artificial tooth on top. An abutment screw often holds the abutment to the body.

What is an abutment on a dental implant?

The short connecting post between the implant body in the bone and the crown. It is fixed to the body, often with a screw, and it passes through the gum.

What part of a dental implant replaces the root?

The implant body, also called the fixture. It is set into the jawbone in the place of the lost tooth's root.
