Bone regrafting after unsatisfactory mandibular reconstruction.

Abstract

Reconstruction of the lnandible was performed through bone grafting fbllowing ma-ndibular resection in five patients with extensive ameloblastoma. Because of unsatisfactory results due to infection, fracture of the graft and pseudoarthrosis formation, reconstructions were attempted employing a graft from a rib, ilium or the lower border of the mandible. As a result, the con-tour and function of the mandible improved and dentures were successfully applied over a period of 20 or 3 years. In this paper, the causes and procedures of the unsatisfactory results following mandibular reconstructtion are discussed.
