title: Osteoplastic reconstruction of severely resorbed maxilla by stack plasty: combining sinus augmentation with lateral and vertical onlay bone grafting.
abstract: Progressive loss of the alveolus with aging leads to defects in the buccolingual and vertical dimensions. Maxillomandibular spatial discrepancies and deficits in sagittal facial projection develop at the same time as deficiencies of the periodontal unit, alveolar bone, and attached gingiva increase, depending on the extent of the atrophy. To restore the anatomy, a sinus lift should be combined with lateral and vertical bony augmentation in an osteoplastic procedure. To achieve this, "block over block" replacement with bone from the iliac crest allows precise functional and aesthetic restoration of the alveolus and the nasomaxillary region by combining inlay, interpositional, and onlay grafting. To our knowledge, preprosthetic osteoplastic reconstruction with stacked bone grafts has not previously been documented with a large number of patients. We report the results of this procedure in 62 patients with severe maxillary atrophy.
