A natural tooth has two main components: The Crown and the root. The crown is the visible part of the tooth and the root is located below the gumline, in the bone of the jaw.

Implantology is the branch of dentistry dedicated to dental implants. The dental implant is an artificial tooth root that is inserted into the jawbone (either the maxilla or the mandible). It often takes the form of a screw that is composed of titanium or titanium alloy.
