Implant is a bio compatible titanium capsule like device placed in the bone on which a crown is fixed without disturbing the adjacent teeth. Implant is a very good and safe option in case one does not want to get adjacent teeth grinded, as needs during bridge placement. There are different designs of an implant. The most relevant design is selected by a dentist looking at the OPG X- Ray and sometimes CT-Scan of the teeth.
The advantage is better longevity in comparison with tooth supported fixed bridge.
