Familial aggregation of mandibular prognathism

April Lee, Chris Yang

Abstract


Mandibular prognathism is a hereditary condition where there is an excess growth of the mandible in relation to the maxilla that can be associated with maxillary retrusion, mandibular protrusion, or both. Skeletal mandibular prognathism is most prevalent in Eastern Asian populations. This paper focuses on a Korean family with skeletal mandibular prognathism that was inherited through three generations. Apparently, neither mandible nor maxilla is retruded in the affected individuals, but there is a concave facial profile. The dentition has a class I occlusion with skeletal mandibular prognathism, and the only way to treat this case would be orthognathic surgery with the help of orthodontic appliances.
