Implants are tooth roots made of titanium. These metallic anchors act as root substitutes. Dental Implants are surgically placed into the jawbone; the bone then integrates with the titanium, creating a strong foundation for artificial teeth (the process s called osseo-integration). Small posts called abutments are then attached to the implant which in turn supports the implant crown. Dental implants can be used to replace a single lost tooth or many missing teeth. Implants also help preserve facial structure, preventing the bone loss, which occurs when teeth are missing for extended period of time.
While high-tech in nature and expensive, dental implants are actually more conservative than traditional bridgework, since implants do not rely on neighbouring teeth for support. They are a stand alone structure which relies solely on the bone for support.
