The 1 to 8 years follow-up results on a group of 15 patients who underwent a Le Fort I osteotomy with interposed bone grafts and who received implants at a second stage, are reported. The procedure proved to be extremely reliable in that sufficient bone was present for maximum size implants, whilst implant survival appeared to be high (94.6%). The forward advancement was stable and no discernible relapse occurred after prosthesis placement. All patients but one were highly satisfied with the aesthetic result and the rehabilitation of function.

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.
