AbstractThe current review was undertaken to obtain a better understanding of the knowledge base of implant‐assisted complete dental prostheses (fixed and removable) in the treatment of the completely edentulous maxilla or mandible. Indications, advantages and disadvantages, complications and maintenance issues, as well as the cost‐effectiveness of both treatments, are discussed to help clinicians in their therapeutic decision‐making. In summary, when indicated and depending on the patients’ needs, both removable and fixed implant‐assisted prostheses are highly safe, reliable and satisfactory treatment modalities for the rehabilitation of edentulous jaws. Careful and precise treatment planning is highly recommended to assist the clinician in preventing potential prosthetic failures. The review also reveals that there is still a need for data, generated using robust research methods, on some patient‐based and clinical outcomes.
