Implants are synthetic structures that are placed in the area of the tooth normally occupied by the root. Implants are anchored to the jawbone or metal framework on the bone. The missing tooth root is replaced with an implant, which remains covered under the gum line. A healing period of up to six months allows the implant to take. After healing, the implant is uncovered and an extension is attached. A replacement tooth is affixed to the implant and extension.
