BACKGROUND: "Bare bone graft" with a vascularised iliac crest is a procedure involving no soft tissue for intraoral lining, and the intraoral defect is covered with epithelial cells through secondary healing of the exposed bone. METHODS: A vascularised iliac crest flap is transferred to a segmental mandibular defect intraorally in the position of the osteotomized stump upwardly. Granulation tissue is usually observed on the stump of the bone graft about 1 week after surgery. When sufficient granulation is observed after approximately 4 weeks, "resurfacing" is performed to prevent interference of hypergranulation tissue with epithelization. Resurfacing involves wiping the granulation tissue from the surface of the bone and covering with a plastic prosthesis fitted to the alveolus. RESULTS: A total of 11 patients underwent bare bone graft with a vascularised iliac crest. Resurfacing was performed at an average of 2.1 times for each patient. All wounds in the oral cavity were completely epithelialized from 2 weeks to 3 months after surgery. Complications with the recipient side occurred in four patients. CONCLUSIONS: Bare bone graft with the iliac crest is one favourable option for mandibular reconstruction utilising the particular shape of the bone without the attached soft tissue.
