Bimaxillary osteotomies and a sliding genioplasty were performed to correct mandibular micrognathia and maxillary vertical hyperplasia in a 19-year-old white male with a Class II, division 1 malocclusion and anterior open bite. At a follow-up appointment with the orthodontist 4 weeks after the surgical procedure, the mandibular anterior teeth showed severe gingival recession, exposing labial root surfaces on the mandibular central incisors. Grafting procedures were able to restore labial soft tissue on the affected teeth. It is suggested that wound healing contraction of gingival tissue in the area of the incision for the genioplasty caused this complication.
