The medium-term results of 12 patients that underwent reconstruction of the severely resorbed maxilla are reported. The method described entails a two-step procedure including Le Fort I osteotomy and grafting of the floor of the sinus and nose with particulate bone and hydroxyapatite (HA). The implants were placed in a second procedure. A 5% failure rate was noted in those patients that were grafted with particulate bone mixed with HA.
