چکیده
Gereç ve Yöntemler: Çalışmaya her biri 40’ar bireyden oluşan 3 grup dahil edilmiştir: bir Sınıf I oklüzyon grubu (14 erkek ve 26 kadın; yaş ortalaması 14.68±1.86), bir Sınıf II oküzyon grubu (12 erkek, 28 kadın ; yaş ortalaması 14.02±1.74), ve sınıf II subdivizyon oklüzyon grubu (19 erkek and 21 kadın; yaş ortalaması 14.32±2.42). Her bir hasta için panoramik radyogramlarda(OPG) sekiz doğrusal ve bir açısal ölçüm yapılmıştır. Sağ ve sol ya da Sınıf I ve Sınıf II tarafların ölçümlerini kıyaslamak için Wilcoxon testi kullanılmıştır. Grup içi değerlendirmelerde P <0,05 seviyesindeki asimetrilerin kıyaslanması için Kruskal-Wallis ve post-hoc MannWhitney U testleri kullanılmıştır.

Cone-beam computed tomographic evaluation of the temporomandibular joint and dental characteristics of patients with Class II subdivision malocclusion and asymmetry
OBJECTIVE Treating Class II subdivision malocclusion with asymmetry has been a challenge for orthodontists because of the complicated characteristics of asymmetry. This study aimed to explore the characteristics of dental and skeletal asymmetry in Class II subdivision malocclusion, and to assess the relationship between the condyle-glenoid fossa and first molar. METHODS Cone-beam computed tom...
متن کاملEvaluation of the role of unilateral and bilateral tooth extraction treatment on maxillary arch symmetry in Class II subdivision cases
Background and Aim: Unilateral extractions have been proposed as potential treatment options to correct Class II subdivision malocclusion, suggesting that most side effects associated with asymmetrical mechanics can be avoided, however the post-treatment arch form may not be symmetrical. Therefore, the aim of this study was to determine the post-treatment effects of unilateral premolar extrac...

BACKGROUND This study cephalometrically compared the dentoskeletal and soft tissue changes consequent to one and three-premolar extraction protocols of class II subdivision malocclusion treatment. METHODS A sample of 126 lateral cephalometric radiographs from 63 patients was selected and divided into two groups. Group 1 consisted of 31 type 1 class II subdivision malocclusion patients treated...
متن کاملLateral cephalometric diagnosis of asymmetry in Angle Class II subdivision compared to Class I and II
INTRODUCTION Lateral cephalometric radiographs are traditionally required for orthodontic treatment, yet rarely used to assess asymmetries. OBJECTIVE The objective of the present study was to use lateral cephalometric radiographs to identify existing skeletal and dentoalveolar morphological alterations in Class II subdivision and to compare them with the existing morphology in Class I and II ...
متن کاملSubmentovertex cephalometric analysis of Class II subdivision malocclusions.
Submentovertex cephalometric analysis was used to assess the mandibular symmetry of 20 patients with Class II subdivision malocclusion and 20 controls with Class I occlusions. Using the intercondylar line and the intercondylar axis, the relative differences were measured between mandibular landmarks in both anteroposterior and transverse dimensions. Anteroposterior and transverse differences be...
