Objection: Open bite malocclusion is one of the most difficult cases in dentistry. This malocclusion is not only a problem related to the dental component, but also a skeletal component. One of the frequently used methods in the treatment of skeletal open bite in adult patients is the technique of orthodontics and orthognathic surgery. Case: Here we report a oligodontic patient with lateral open-bite who treated with orthodonticssurgery-prosthesis cooperation. A 17-year-old female patient was admitted to our university with the complaint of incorrect bite and dislike the appearance of her teeth. The patient had 1 mm overjet and 7 mm openbite between the right and left posterior molar teeth.Depending on the oligodontism, there is a congenital retardation in three parts of the alveolar bone. Bilateral sagittal split osteotomy was performed in a clockwise rotation of approximately 17 degrees to the mandible. The perpendicular dimensions of the patient were increased with posterior rotation, the jaw tip was reduced, and the posterior openbite was corrected. The guide splint is manufactured in such a way that it provides 1 mm anterior thickness and 2 mm thickness in the posterior part in order to make the previously planned prosthetic restoration after surgery. Conclusion: After 30 months of orthodontic treatment, Class I molar-canine relationship was obtained. Openbite is closed by mandibular rotation. Oligodontia was corrected by prosthetic restoration. In the light of these results, it was seen that orthognathic surgery was successful in openbite cases and multidisciplinary approach was necessary for treatment efficacy.
