A<unk>  is an<unk>  (bone prominence) on the<unk>  surface (cheek side) of the alveolar ridge of the maxilla or mandible. More commonly seen in the maxilla than the mandible,<unk>  are considered to be site specific. Existing as asymptomatic bony nodules,<unk>  don’t usually present until adult life, and some consider<unk>  to be a variation of normal anatomy rather than disease. Bone is thought to become hyperplastic, consisting of mature cortical and trabecular bone with a smooth outer surface. They are less common when compared with mandibular tori.
