Exostosis: A donor site for autograft.

This article reports the utilization of exostosis as a source of autogenous bone for the treatment of osseous defects. A patient presented with an exostosis on the mandibular lingual region on the right side of the jaw. Exostosis was surgically removed using a chisel and mallet. The autograft thus obtained was used to treat a shallow osseous crater between 46 and 47. New bone formation was noticed at the grafted site 6 months after grafting. Bone formed in the grafted areas showed comparable clinical features to those of native bone.
