Dental implantology is a set of surgical techniques aiming at the functional rehabilitation of a patient affected by total or partial edentulism, by using dental implants, i.e. metal elements surgically inserted in the mandibular or maxillary bone, or above them but under the gum. These elements are fitted with connectors to fasten them to fixed or removable prostheses, to enable chewing functionality. Such implants can have different shapes, they can be inserted in different positions, with different techniques, then connected to prostheses at different times.
