An autogenous ilial graft was experimentally used for grafting the mandibles of 6 mixed-breed dogs, aged 1 to 5 years. To prepare the recipient bed, the mandibular shaft, under the fourth premolar tooth, was cut 2 cm deep and removed with the tooth. An ilial graft, the same size as the excised mandibular shaft, was harvested from the dorsal iliac crest of the same dog. The graft was then seated in the recipient bed and fixed to the mandible by a plastic bone plate and screws. Bone union was evaluated radiographically and histologically. The grafted sites of all dogs were postoperatively radiographed on the day of grafting and then every 2 weeks for a period of 12 weeks in 3 dogs, but for 4, 8 and 12 weeks in the other 3 dogs before being harvested for histological study. Callus formation and bone union appeared 6 and 12 weeks after grafting, respectively. It was concluded that, the ilial wing can be used for mandibular autogenous grafting.
