The concept of “All-on-Four” is based on placing four conventional implants in the anterior part of fully edentulous jaws to support a provisional, fixed, and immediately loaded full-arch prosthesis. The technique stabilizes bone levels, keeping the jaws healthy. The Combination of tilted and straight implants for supporting fixed prostheses can be considered a viable treatment modality resulting in a simpler and less time consuming procedure, significantly less morbidity, decreased financial costs and a more comfortable postsurgical period for the patients. The technique also stabilizes bone levels, keeping the jaws healthy.
