A vertically deficient posterior maxillary edentulous ridge in conjunction with sinus pneumatization or extensive horizontal bone resorption presents significant challenges for implant placement and restoration with an implant-supported fixed prosthesis. Various surgical techniques have been reported for the reconstruction of the vertically deficient posterior maxilla: guided bone regeneration, sinus elevation, block and/or particulate grafting with barrier membranes, and distraction osteogenesis. This clinical report describes the technique, the management of intrasurgical complications, and the 3-year follow-up results of augmenting the vertically deficient posterior maxilla with a segmental osteotomy prior to rehabilitation with an implant-supported fixed prosthesis.
