The current trends in extensive oral rehabilitation involve the achievement of screw-retained implantsupported restorations. Marketing and efforts to meet patient demands have led to a single type and method of rehabilitating maxillary or mandibular edentulous patients to become predominant and become a kind of "universal panacea" in the treatment of this type of complete edentulism. The conference aims to discuss the fundamental principles directly involved in therapeutic decision algorithms regarding the approach to this subject and to draw guidelines regarding the appropriate therapeutic decision that provides predictability for this type of implant-supported restorations.
