Abstract

Mandibular midline distraction is a treatment alternative of cases which have anterior crowding with mandibular transversal deficiencies While traditional approaches such as extractions, stripping, dental tipping or mandibular arch expansion can resolve the deficiency, treatment of transverse discrepancies with mandibular expansion or incisor protrusion has been shown to be unpredictable and could result in relapse and undesirable side-effects in the long term. This case report describes treatment with fixed mechanics after mandibular midline distraction and RME in A 14-year-old female patient with V-shaped mandibular arch and upper and lower anterior crowding. After the treatment, satisfying esthetic appearance and functionally sound occlusion was obtained

Alt Çene Orta Hat Distraksiyonu: Olgu Sunumu

Abstract

Alt çenenin orta hat distraksiyonu, dar apikal kaideye sahip alt çenenin transversal yöndeki yetersizliği ile birlikte ön dişlerde çapraşıklığın mevcut olduğu olgularda uygulanabilecek bir yaklaşımdır. Diş çekimi, stripping, tipping veya alt çene ark genişletmesi tedavi seçeneği olarak düşünülebilirken, bu tedavilerin uzun dönem sonuçlarının öngörülemeyeceği ve nüks ile karşılaşılabileceği bildirilmiştir. Bu olgu sunumunda; üst ve alt ön dişlerinde çapraşıklık şikâyeti olan ve V şekline sahip alt arka sahip 14 yaşındaki kadın hastanın hızlı üst çene genişletmesi ve alt çene orta hat distraksiyonu sonrası sabit mekaniklerle tedavisi sunulmaktadır.Tedavinin tamamlanmasının ardından memnun edici bir estetik görünüş ve fonksiyonel anlamda sağlıklı bir kapanış elde edildi
