Amaç: İki farklı tedavi yaklaşımının sefalometrik ölçümler ve ark genişlikleri üzerindeki etkilerini karşılaştırmaktır. Gereç ve Yöntemler: Sınıf I maloklüzyona sahip ve orta-şiddetli çapraşıklığı bulunan 45 bireyin sefalometrik radyografileri ve dental modelleri elde edilmiştir. Bireyler çekim yapılmayan (birinci) ve dört premolar çekimli (ikinci) olmak üzere iki gruba ayrılmıştır. Birinci grup, Damon Q sistemi ile tedavi gören 22 hastadan (9 kız, 13 erkek ortalama yaş 18.0 ± 1.68) oluşmakta iken ikinci grup konvansiyonel MBT braket sistemi ile tedavi edilen 23 hastadan (11 kız, 12 erkek yaş ortalaması: 17.9 ± 1.34) oluşmaktadır. Hastaların tedavi öncesi ve sonrası lateral sefalometrik radyografileri ve ark genişlikleri ölçülüp karşılaştırılmıştır. Her gruptaki tedavi değişikliklerini değerlendirmek için eşleştirilmiş örnekler t-testi kullanıldı. Gruplar arasındaki değişiklikleri karşılaştırmak için bağımsız örnekler t-testi yapıldı. Bulgular: Her iki grupta da tedavi ile sagital ve vertikal iskeletsel değerlerde istatistiksel olarak anlamlı bir değişiklik görülmemiştir (p>0,05). Üst ve alt kesici dişlerde birinci grupta anlamlı proklinasyon gözlenirken (p<0,01); ikinci grupta mandibular dişlerde anlamlı (p<0,05) retroklinasyon bulunmuştur. Dudakların birinci grupta belirgin olarak protrüze olduğu ve üst dudağın inceldiği gözlenmiş (p<0,01), ancak ikinci grupta istatistiksel olarak anlamlı bir değişiklik gözlenmemiştir (p>0,05). Birinci grupta tüm transvers dental model ölçümlerinde anlamlı (p<0,01) artış tespit edilmiş, ancak ikinci grupta sadece intermolar genişliklerde anlamlı bir azalma gözlenmiştir (p<0,01). Sonuç: İki tedavi yöntemi dental ve yumuşak dokular ile ark genişlikleri üzerine birbirine zıt ve anlamlı etkiler göstermiştir.

Objectives: To compare the effects of two different treatment approaches on cephalometric measurements and arch widths.
Materials and Methods: The retrospective study evaluated pre- and post-treatment cephalometric radiograms and dental models of 45 patients with Class I malocclusions and moderate-severe dental tooth size arch length discrepancies that underwent extraction or nonextraction treatment between 2015 and 2020. Group I (n=22 [9 female, 13 male]; mean age, 18.0 ± 1.68 years) was treated with the Damon Q bracket system and Group II (n=23 [11 female, 12 male]; mean age, 17.9 ± 1.34 years) was treated with the conventional MBT bracket system. Pre- and post-treatment lateral cephalometric radiograms were obtained and arch widths were measured for each subject. Paired samples t-test was used to evaluate the treatment changes within each group. To compare the changes between groups, independent samples t-test was performed.
Results: No significant change was detected in the sagittal and vertical skeletal parameters in both groups (p>0.05). The upper and lower incisors proclined significantly in Group I (p<0.01) and the mandibular incisors retroclined significantly in Group II (p<0.05). The lips protruded significantly and the upper lip thickness decreased significantly in Group I (p<0.01), whereas no significant difference was observed in Group II (p>0.05). All the transversal dimensions increased significantly in Group I (p<0.01), while only the intermolar distance decreased significantly in Group II (p<0.01).
Conclusions: Both treatment methods provided significantly different outcomes with regard to soft tissue parameters and arch widths.
