In this case report, we present an extraction-prescribed Class II division 1 adult patient's non-extraction treatment by distalization of the total maxillary arch with miniscrews. The miniscrews were inserted into the mesial of the upper first molars roots as far as possible, and total arch distalization was started by a nitinol coil spring (200 g per side) extended from the miniscrew to a hook attached between the canine and lateral. The distalization amount was expected to be the distance between the miniscrew and the second premolar root per side. At the end of the treatment, 2 mm molar distalization with 3 degree tipping was achieved. Class II division I adult patients with moderate overjet can be treated without extraction using these mechanics.

Bu olgu raporunda büyüme ve gelişimi tamamlanmış Sınıf III maloklüzyona sahip bir hastanın ortodontik ve cerrahi tedavisi sunulmuştur. 17 yaşındaki bayan hasta, alt çene ileriliği, üst çene geriliği ile karakterize iskeletsel ve dental Sınıf III maloklüzyon özelliklerini taşımaktaydı. Hastanın 14 ay süren cerrahi öncesi ortodontik tedavisinde kapaklı braketler tercih edilmiştir. Ortodontik tedaviyi takiben alt ve üst çene arasındaki iskeletsel uyumsuzluğunu düzeltmek için her iki çeneye de cerrahi müdahale yapılmıştır. Cerrahi sonrası yapılan ortodontik tedavi ile dişler uygun konumlarına getirilerek oklüzyon düzeltilmiş ve diş çekimi yapılmaksızın iskeletsel ve dişsel Sınıf I ilişki ile ideal bir yumuşak doku profili elde edilmiştir. İskeletsel Sınıf III maloklüzyonların ortodonti ve ortognatik cerrahi kombinasyonuyla tedavisinde kapaklı braketlerin kullanılması ile tedavi verimliliği arttırılarak daha estetik ve stabil sonuçlar sağlanmıştır.Anahtar kelimeler: Sınıf III maloklüzyon, ortognatik cerrahi, kapaklı braket.

Developmental, traumatic and congenital factors, among many others, may lead to transverse maxillary deficiency (TMD). TMD can be corrected by orthodontic treatment, and may also require surgical intervention. The surgical technique is used in maxillary hypoplasia seen in cleft palate, crowding in maxillary teeth, which in cases where maxilla needs to be expanded more than 5 mm. Although it is a frequently used technique, there is no consensus on the operative technique and the apparatus used during the operation. Whether or not to separate, the pterygomaxillary junction is also one of the most common subjects of debate in this regard. In this case presentation, the transverse expansion of the maxilla was completed by means of surgically-assisted rapid maxillary expansion operation performed under local anesthesia without separating the pterygomaxillary junction and nasal septal osteotomy; and the patient, in whom orthodontic treatment had been completed, made a successful recovery without complications.
