title: Subpontic cartilagenous hyperplasia of the mandible.
abstract: We report here a case of subpontic cartilagenous hyperplasia of the lower first molar of a 65-year-old woman. A sessile mass of calcifying hyaline cartilage firmly attached to the alveolar ridge was found below the pontic of a fixed partial denture. This is a novel type of reactive cartilagenous metaplasia in the subpontic tissue.
