Clinical application and research progress of All⁃on⁃Four

Abstract

To seek convenient and effective method for reconstruction of edentulous jaw, Maló and his colleagues de⁃ veloped All⁃on⁃Four implant immediate⁃function concept. The principle of All⁃on⁃Four is to support the full⁃arch pros⁃ thesis by 4 implants and to achieve immediate loading after surgery. Its advantages include avoiding additional bone grafting, evading critical anatomical structures and immediate prosthesis. In recent years, All ⁃ on ⁃ Four technique has been widely utilized in clinical practice as a viable approach for edentulous patients. With the auxiliary of guided sur⁃ gery and biomechanical researches, All ⁃on ⁃Four has achieved predictable clinical results. In this paper, the develop⁃ ment, investigation of biomechanics and main points of surgery and prosthesis of All⁃on⁃Four were briefly reviewed.
