  In clinical practice, many a times, fixed prosthesis for edentulous patients requires alternative approach due to severely resorbed ridges or large antra or financial reasons preventing placement of a sufficient number of implants for prosthetic rehabilitation. The rehabilitation of such arches requires bone graft, bone augmentation procedures to facilitate implant placement and loading for function. However, to avoid additional surgeries, cost, extended length of treatment, and co morbidities precluded others to become innovative and to circumvent these procedures and problems. In an effort to solve this problem, the concept of angled distal implants was introduced. This technique favoured many clinicians in terms of stability, anchorage, retention and immediate loading of implant supported prosthetic treatment. It also eliminated many problems of cantilevering and additional surgical protocols like grafting or augmentation that is usually encountered in treatment plan of implant retained prosthesis.

  The aim of this article is to systematically review the literature on All on Four Implants regarding its principle, evolution, biomechanics inclusion criteria and prosthetic management.
