The “ALL ON FOUR” treatment concept was developed to maximize the use of the remaining bone available in atrophic jaws. This procedure is indicated for patients who have already been completely edentulous for at least one year before the procedure. The protocol uses four implants in the anterior part of completely edentulous jaws to support a provisional, fixed and immediately loaded temporary prosthesis (in certain patients).
In the all-on-four technique, acrylic prostheses are used for mechanical reasons, as ceramic prostheses exert too much force on the implants.
This procedure is performed in an operating room under intravenous sedation supervised by a board-certified anesthesiologist who specializes in this type of surgery.
