Implantology, a branch of dentistry focused on dental implants.The dental implant is a root of the artificial tooth which is inserted into the maxillary bone (maxilla or mandible). It often takes the shape of a screw made of titanium or titanium alloy. Dental implants can be considered for patients who lack one or more teeth. A dental implant alone does not replace a natural tooth. An abutment must be mounted on the implant once it has been inserted into the maxillary bone. Depending on the number of teeth to be replaced, an artificial crown, a total or partial prosthesis or a bridge will be prepared and installed on the abutments. If the patient has only one missing tooth, a single crown will suffice.
