Introduction: Atrofic maxillas do not allow dental rehabilitation, it is therefore necessary to perform a previous structure reconstruction that allows the installation of implants. The purpose of this work is to show the team experience in the rehabilitation of this type of patients.

Materials and patients: 46 patients treated between 2004 and 2010 will be presented. 15 reconstructions were performed using Calvarium grafts and 31 using interpositional bone grafting of Iliac Crest in connection with Le Fort I ostetomy. 115 Oseo Integrated Implants were installed on patients treated with Calvarium grafts and 244 were installed to the patients treated with Iliac Crest graft.

Results: 2 out of 15 patients (1 male and 14 females), treated with Calvarium graft, suffered a partial graft loss. 6 out of 114 installed implants suffered osseointegration failure (5% failure).

From the 31 patients treated with Le Fort I osteotomy (9 males and 22 females), 13 were done with anterior Iliac Crest graft and 18 with posterior Iliac Crest graft. Complete loss of the unilateral graft was observed in 1 patient (3%). Sinusitis and partial bone loss were observed in 15 patients (48%). 17 out of 244 installed implants suffered osseointegration failure (7% failure).

Conclusion: Maxillas reconstruction using Calvarium or Iliac Crest autologous extraoral graft is adequate for implant’s installation and patient rehabilitation considering the indication is accurate and the adequate protocols are followed.
