A crown and one single dental implant can be used to replace a missing single tooth and its root. The affected single tooth can be replaced without compromising with the health of the adjacent teeth only by a dental implant. Whereas, in other dental procedures dedicated to cure the lost single tooth, the neighboring teeth are grounded down to support the cemented bridge. This artificial tooth root preserves the tooth by holding a replacement of a tooth or a bridge. The dental implants are fixed into the jawbone surgically.
