A dental implant is essentially an artificial tooth root that is surgically placed into the jawbone. One or more missing teeth can be replaced by attaching a crown, a fixed bridge, or a full set of dentures on top of the implants. The implant material, which is typically pure titanium, is extremely biocompatible since the bone treats the implant just as if it were bone. The effect is that the bone cells attach themselves to the implant and the interface between the bone and the implants is termed osseointegration. After an initial healing period, during which the implant(s) is left undisturbed underneath the gum tissue, it is uncovered and connected to a small post that serves as the foundation for the tooth or teeth that the implant will be supporting.
