Treatment of lateral open bite with vertical dentoalveolar distraction osteogenesis

•Open bite persistent to conventional mechanics was treated by vertical distraction.•Distraction of dento-osseous blocks was achieved by Ni-Ti arch wires and elastics.•Less treatment time and no periodontal complications are the advantages of this method.

The aim of this article is to describe the surgical, orthodontic, and periodontal treatment of an adult patient with a lateral open bite, anterior crowding, and gingival recession on the mandibular right lateral incisor. The lateral open bite, which resisted conventional mechanics, was successfully corrected by the combination of dento-osseous osteotomies and vertical alveolar distraction using orthodontic multibracket appliances in conjunction with nickel-titanium archwires and intermaxillary elastics. After the orthodontic treatment, the denuded root surface of the mandibular right lateral incisor was closed using a coronally advanced flap technique with platelet-rich fibrin. The results at the 2-year posttreatment follow-up were satisfactory from both the occlusal and the periodontal standpoints.
