Aim: The purpose of this research was to examine and compare the effects of two different designs of the Twin-Block TWB appliance on the position and angle of the lower anterior teeth.Material and Method: A total of 30 individuals during the peak pubertal period with Class II Division 1 malocclusions were included in our study. Individuals were randomly divided into 2 groups to apply the TWB appliance containing acrylic or clasps on the lower anterior teeth. The analysis of cephalometric films of individuals were evaluated at pre-treatment T0 and post- treatment T1 to determine the changes of the lower anterior teeth. Shapiro Wilk and two-way ANOVA analysis were used for the analysis of the data.Results: Statistically significant difference was found in all measures expressing lower teeth positions at T1 in both groups p

Amaç: Bu araştırmanın amacı; Twinblok TWB apareyinin iki farklı dizaynının alt keser dişlerin konumları ve açılarına olan etkilerini incelemek ve karşılaştırmaktır.Gereç ve Yöntem: Araştırmamızda büyüme ve gelişim döneminde bulunan, Sınıf II Bölüm 1 maloklüzyona sahip toplam 30 birey dahil edilmiştir. Bireyler, alt keser bölgesinde akrilik veya kroşe içeren TWB apareyi uygulanmak üzere rastgele 2 gruba ayrılmıştır. Bireylerden tedavi öncesi T0 ve tedavi sonrasında T1 alınan sefalometrik filmlerin analizi ile alt keser dişlerde meydana gelen değişiklikler değerlendirilmiştir. Verilerin analizinde Shapiro Wilk ve Çift yönlü varyans analizi kullanılmıştır.Bulgular: Her iki grupta da T1’de alt keser konumlarını ifade eden tüm ölçümlerde istatistiksel olarak anlamlı fark bulunmuştur p
