Treatment of Functional Class III Malocclusion Associated with Retrognathic Maxilla by Double Hinged Maxillary Expansion Device and Sequential Rapid Maxillary Expansion-Constriction Protocol - Case Report

Abstract

In this case report, the clinical results of treatment with the consecutive Rapid Maxillary Expansions and Constrictions SRME-C protocol were presented using the double-hinged extension device of Class III malocclusion maxillary retrusion from the maxilla. A double-hinged expansion screw was bonded bilateral upper first premolar and first molar teeth and the screw was opened two times in the morning and evening on the first week, extending 1 mm per day in total; In the 2nd week morning and evening 2 times were closed and maxilla was narrowed 1 mm per day in total. This manner was continued for 9 consecutive weeks. Positive overjet was obtained at the end of nineth week and fixed treatment was started after initial material was taken T2 as before.

MAKSİLLER RETROGNATİ KAYNAKLI FONKSİYONEL SINIF III MALOKLUZYONUN ÇİFT MENTEŞELİ MAKSİLLER GENİŞLETME APAREYİ VE ARDIŞIK HIZLI MAKSİLLER GENİŞLETME-DARALTMA PROTOKOLÜ UYGULANMASI İLE TEDAVİSİ VAKA RAPORU

Abstract

Maksiller genişletmenin Angell tarafından ortodonti literatürüne kazandırılmasından bugüne kadar, çok çeşitli maksiller genişletme aygıtı ile farklı genişletme protokolleri uygulanmıştır. Bu vaka raporunda maksiller kaynaklı Sınıf III malokluzyonun çift menteşeli maksiller genişletme apareyi kullanarak Ardışık Hızlı Maksiller Genişletme ve Daraltma AHMG-D protokolü ile tedavisinin klinik sonuçları sunulmuştur. Bilateral olarak üst premolar ve molar dişlere çift menteşeli genişletme plağı simante edilmiş ve vida, birinci hafta sabah-akşam 2 tur açılarak toplamda maksilla günde 1 mm genişletilmiş; 2. hafta sabah-akşam 2 tur kapatılarak toplamda maksilla günde 1 mm daraltılmıştır. Bu uygulamaya birbirini takip eden 9 hafta boyunca devam edilmiştir. Dokuzuncu hafta sonunda pozitif overjet elde edilmiş ve başlangıçtaki materyal alındıktan sonra T2 sabit tedaviye başlanmıştır.
