Two cases of bare bone graft with dental implant for mandibular defect

Abstract

AbstractBare bone graft is a method of mandibular reconstruction involving vascularised iliac bone graft without a skin flap, and secondary epithelialisation of the exposed iliac bone surface in the oral cavity. We herein report two cases of bare bone graft with dental implant for mandibular defect after tumour resection. Case 1: A 36‐year‐old woman with odontogenic myxoma of the left mandible underwent reconstruction with a free vascularised iliac flap after segmental resection of the mandible. The exposed iliac bone surface in the oral cavity required about 2 months for epithelialisation. Two implants were placed into the reconstructed mandible 12 months after initial surgery, and prosthetic rehabilitation was performed successfully after 6 months of osseointegration period. Case 2: A 32‐year‐old woman with desmoplastic ameloblastoma of the right mandible underwent reconstruction using free iliac bone after segmental resection of the mandible. As the reconstructed bone failed after surgery, the left mandible was reconstructed using a free vascularised iliac flap. The exposed iliac bone surface in the oral cavity required about 2 months for epithelialisation. Four implants were placed into the reconstructed mandible 17 months after surgery, and prosthetic rehabilitation was performed successfully after 6 months of osseointegration period. In both cases, the mandibular contour and occlusal function were satisfactory.
