A dental implant is designed to replace the root of a missing tooth. An implant may act as an anchor to support a crown when a single tooth is missing. Two or more implants may support a bridge to replace several teeth. An implant may also provide support for a removable denture.
Dental implants are made of materials that are accepted extremely well by the body (such as titanium). After the implant is placed into the bone, the bone fuses to it in a process known as osseointegration.
