Abstract

Aim: The aim of this study was to compare the dentoalveolar, skeletal and soft tissue effects of upper two premolar extraction or nonextraction treatments after Rapid Maxillary Expansion (RME). Subjects and Methods: The sample of this study consisted of pre and posttreatment lateral cephalometric radiographs of 21 patients characterized by narrow maxilla and treated with or without extraction following RME. In our study, RME applied patients were divided into two groups as extraction and nonextraction. After adequate expansion and retention period, two upper first premolars were extracted in extraction group and no teeth were extracted in nonextraction group. Thereafter, fixed orthodontic treatment was started in two groups. Results: At the end of treatment when extraction and nonextraction groups were compared, significant differences in A1 inclination to A-Po angle (p < 0.01), A 7 to A-Po plane (p < 0.05) and B1 to A-Po plane distance (p < 0.05) representing the dentoalveolar incisor position were detected. Also statistically no significant differences were found between parameters related to lips or soft tissues. Our results do not support the idea that more retrusive profile occurs as a result of upper extraction treatment. Conclusions: In the light of these results, it is possible to say that there is no esthetic difference between the RME appliances applied patients treated by either upper premolar extraction or nonextraction tre¬atment.

Özet

Amaç: Bu çalışmanın amacı, hızlı üst çene genişletmesi (RME) sonrasında, iki adet üst birinci premolar çekimli ve çekimsiz tedavinin, dentoalveolar, iskelet- sel ve yumuşak dokuya olan etkilerinin karşılaştırılmasıdır. Bireyler ve Yöntem: Bu çalışmanın materyali, maksiller darlığa sahip ve RME'yi takiben çekimli ya da çekimsiz olarak tedavi edilmiş 21 hastanın, tedavi öncesi ve sonrası lateral sefa- lometrik radyografilerinden oluşmaktadır. Çalışmamızda RME uygulanan hastalar, çekimli ve çekimsiz olmak üzere iki gruba ayrıldı. Yeterli genişletme ve pekiştirme süreci sonrasında, çekimli tedavi edilen gruptan, iki adet üst birinci premolar diş çekildi, çekimsiz grupta ise herhangi bir diş çekimi yapılmadı. Daha sonra her iki gruba da sabit ortodontik tedavi uygu¬landı. Bulgular: Tedavi sonunda, çekimli ve çekimsiz tedavi edilen gruplar karşı¬laştırıldığında, üst kesici dişin uzun ekseninin A-Po doğrusuyla yaptığı açı (p < 0.01) ve mesafesinde (p < 0.05) ve alt kesici dişin A-Po doğrusuna olan mesafesinde (p < 0.05) anlamlı değişiklikler tespit edildi. Bununla beraber, dudaklar ya da yumuşak dokular ile ilgili parametrelerde istatistiksel olarak anlamlı farklılıklar bulunmadı. Bizim bulgularımız, üst çekimli tedaviler sonucunda daha retrü- ziv bir profil oluşur fikrini desteklememektedir. Sonuçlar: Bu bulguların ışığında, RME apareyi uygulanan, üst çekimli ya da çekimsiz tedavi edilen hastalarda, estetik farklılık olmadığını söylemek mümkündür. (Türk Ortodonti Dergisi 2010;23:49-60)
