When a patient has lost a functional tooth, a single dental implant is placed into the upper or lower jaw bone as a tooth root to support a new tooth crown. Dental implants are the longest lasting dental restorations with the highest success and survival rates in the field of dentistry today. A dental implant supported tooth is the most natural and longest lasting way to replace a tooth that is lost. Implant supported crowns are permanently attached and no teeth have to be taken in and out of the mouth.
