Abstract

Objective: The present study aims to evaluate the impacts of the upper incisor teeth intrusion in deepbite patients by two different techniques to the permanent maxillary first molar tooth using the three-dimensional cephalometric analysis in the individuals. Materials and Methods: The population of this study consists of 34 patients with >4 mm overbite and a >=2 mm gummy smile during post-pubertal period. Patients who underwent intrusion of upper incisor teeth were randomized to receive Connecticut intrusion arch (CTA) or miniscrew anchorage intrusion system (MAIS) to compare the impacts on permanent maxillary first molar teeth. Cone Beam Computed Tomography (CBCT) data obtained before (T1) and after (T2) intrusion were evaluated through three-dimensional (3D) cephalometric analysis. Intragroup assessment of treatment-related variables were performed via "t-test in dependent samples" and intergroup comparisons were assessed by "t-test in independent samples". Results: In patients who underwent intrusion of upper incisors, permanent maxillary first molar teeth became deviated distally (1.48 mm/7.63 degree) only in CTA group, a statistically significant difference was found between two groups (p

Özet

Amaç: Bu çalışmanın amacı, derin örtülü kapanışa sahip bireylerde üst kesici dişlerin farklı tekniklerle intrüzyonunun daimi üst 1. Molar dişe etkilerinin 3 boyutlu sefalometrik analiz ile karşılaştırılmasıdır. Materyal ve Metot: Araştırmamıza, postpubertal dönemde, overbite'ı >4mm. ve dişeti gülümsemesi >=2 mm. olan toplam 34 hasta dahil edilmiştir. Hastalar rastgele bir şekilde Connecticut intrüzyon arkı (CTA) ile minivida ankrajlı intrüzyon sistemi (MAİS) gruplarına ayrılarak üst kesici dişlerin intrüzyonu gerçekleştirilen bireylerde üst 1. büyük azılarda ortaya çıkan etkileri değerlendirilmiştir. İntrüzyondan önce (T1) ve sonra (T2) alınan konik ışınlı bilgisayarlı tomografi (KIBT) verileri 3 boyutlu (3D) sefalometrik analizle incelenmiştir. Tedaviye bağlı değişenlerin grup içi değerlendirilmesinde "Bağımlı örneklerde t-testi"; gruplar arasındaki karşılaştırılmasında uygulanmıştır. Bulgular: Üst kesici dişlerin intrüzyonu gerçekleştirilen hastalarda, üst 1. molar dişler yalnızca CTA grubundaki bireylerde distale devrilmiş (1.48 mm/7.63 derece) ve bu durum gruplar arasında istatistiksel olarak önemli bulunmuştur (p
