Background: Although autologous bone is considered the gold standard among the grafting materials used in implant therapy, it does have a number of drawbacks, in particular morbidity at the site of donation and the limited amount of bone available. To overcome these limitations a number of alternative bone materials have been employed in the last few years. In this study we report the results of the use of homologous fresh-frozen bone from a tissue bank in patients undergoing reconstruction of bone defects in the oral cavity.
Material and methods: Between June 2004 and October 2008, 14 consecutive patients underwent bone reconstruction with fresh-frozen bone from a tissue bank. Four to eight months after surgery, implants were placed in the newly formed bone.
Results: No problems were recorded during the post-operative course. In all cases treatment was successful and osteointegrated implants were placed in the newly formed bone after 4-8 months. All implants showed good osteointegration (100% overall success rate, mean follow-up 20 months), allowing loading with a fixed cemented prosthesis.
Conclusions: Our results support the previous findings that homologous fresh-frozen bone can be considered a valid alternative to autologous bone for the reconstruction of bone defects in the oral cavity in patients undergoing implant therapy.
