In implant dentistry, a clinically appropriate definition for the term "rehabilitation" needs to account for restoring patients' ability to smile, chew, speak, and kiss as closely as possible to those conditions developed with original/pristine tooth-periodontal structures. Vertical dimensions may be altered within partially/complete edentulous patients requiring oral rehabilitation as a consequence of tooth loss, migrations, tilting, and occlusal wear. The clinician of professionals in charge of conducting the process of oral rehabilitation are expected to combine their knowledge, skills, and experience in the fields of periodontics, endodontics, oral and maxillofacial surgery, dental materials, orthodontics, prosthodontics, and implantology in order to achieve the expected and satisfactory results. Didactically, oral rehabilitation can be divided into five phases: diagnostic phase, treatment planning phase, prognosis phase, corrective phase, and follow-up/maintenance and control phase. Diagnostic phase aims to appraise the causes and nature of the tooth loss that occurred in the stomatognathic system, as well as the patient's general health.
