Abstract

AIM:

The aim of the present clinical study is to evaluate the efficacy of autologous bone multiple harvesting in the surgery of the severe atrophic maxilla, in term of quantity and quality of the grafts for the following implant-supported prosthesis treatment.

MATHERIAL AND METHOD:

For 5 patients a combined on-lay bone grafting and bilateral sinus lift elevation procedure was performed under general anesthesia. Harvesting site was anterior iliac crest and calvaria. Clinical and radiographic (Rx-OPT and CT Dentascan) examinations were performed to evaluate the bone defects and to programme surgical treatment and during the follow up.

RESULTS:

Postoperative complications' evaluation showed no significative problems. Radiographic controls at 4 months showed a minimum or no resorption of calvaria harvesting.

CONCLUSION:

In the reconstruction of the severe atrophies of the alveolar edentoulus crests, a multiple extra-oral harvesting seems to improve quality and quantity of bone graft, so that the following implant-supported prosthesis treatment is facilitated.
