A dental implant is a dental device that is used to replace a missing tooth or to serve as an anchor for dentures. The implant consists of a metal post that is implanted into the jawbone where it acts as an artificial root. The post is made of titanium, a metal that is used in many other types of prosthetics as well, including artificial joints. In implant supported bridges and dentures, the post serves as an anchor to keep the denture or bridge securely in place. When replacing a single tooth, implant abutment is placed on the implant and serves as a connector for a dental crown.
