FUNCTIONAL MANDIBULAR RECONSTRUCTION USING OSSEOINTEGRATED IMPLANTS IN VASCULARIZED ILIAC CREST

Abstract

In mandibular reconstruction, the iliac crest provides a sufficient amount of bone graft matreial. Vascularized iliac graft showed little bone resorption and a high viability rate even in primary reconstruction and allowed application of the prosthetic restoration early after surgery. In this study, we review cases in which vascularized iliac crest grafts were used with implants to evaluate whether implants are useful for improving the oral function as comparing with the conventional prosthetic restoration, and whether the vascularized iliac crest provides sufficient support to the implants.
12 patients were performed implant-anchored prosthesis, and 38 Bronemark Mark II, 8Bronemark standard, 7 ITI Bonefit and 2 ITI Hollowscrew implants were inserted via intra oral approach. One of the implants failed to osseointegration initially, and 1 implant was removed, because marked inflammation and bone resorption were observed around it. For implants in three patients were made sleeping implants, because their position were inadequate. After treatment with the implant-anchored prosthesis, masticatory function was improved rather than wearing conventional dentures, but speech function was not improved.
