A 14-year-old girl was referred to our department on September 20, 1985 for a gross radiolucency involving the left molar-ramus region. A biopsy specimen disclosed the lesion to be a follicular-type ameloblastoma with massive proliferation of the mesenchymal stroma.<BR>The tumor was resected, leaving a large defect. However, the bone was expected to be regenerated due to the high osteogenetic potential of the periosteum because of her young age. Maximum preservation of the periosteum and its stabilization by packing the dead space with a porous hydroxyl-apatite ceramic block was regarded to be necessary to avoid iliac bone grafting. In live with this plan, her mandible was immediately reconstructed by interposing the material, 58×25×12 mm in size and 31 g in weight, between the symphysis and the extra-articular condylar head. After 8 years of follow-up, there have been no identifiable signs of morphological or functional disturbances.
