Computer software associated with imaging techniques facilitates diagnosis, planning, and management in cases of severe maxillary atrophy, by reducing the incidence of complications and improving the postoperative course and functional outcome. This article reports on a case of a 66-year-old woman with maxillary atrophy. Computer software was used to plan and position 6 maxillary and 4 mandibular implants, taking maximum advantage of the remaining bone. Bicorticalization was sought by angulation and implant fixation in the buttresses, while rehabilitation was carried out by means of a fixed screw-retained upper prosthesis and a lower overdenture. No implants were lost after 36 months of follow-up. This technique optimized precise implant placement as planned without the need for more complex reconstruction techniques.
