Evaluation of root resorption following rapid maxillary expansion using cone-beam computed tomography

ASLI BAYSAL | MEHMET İRFAN KARADEDE | İLKNUR VELİ

Objective: To evaluate the root resorption after rapid maxillary expansion (RME) via cone-beam computed tomography (CBCT). Materials and Methods: Records of 25 patients who had undergone RME with tooth-borne banded expander were obtained from the archive of the orthodontic department. CBCT data were reconstructed with surface and volume rendering, and the volumetric images were manipulated to display the root surfaces from various orientations. On these three-dimensional images, permanent first molars and first and second premolars were segmented, and their roots were isolated. Volumes ...Daha fazlası

Mandibular asymmetry in unilateral and bilateral posterior crossbite patients using cone-beam computed tomography

İLKNUR VELİ

Objective: To test the hypotheses that (1) there is no difference in mandibular asymmetry between the crossbite and normal side in a unilateral crossbite group (UCG) and between the right and left sides in a bilateral crossbite group (BCG) and a control group (CG); and (2) there is no significant difference in mandibular asymmetry among crossbite groups and control group. Materials and Methods: The cone-beam computed tomography scans of three groups were studied: (1) 15 patients (6 male, 9 female; mean age: 13.51 6 2.03 years) with unilateral posterior crossbite; (2) 15 patients (8 male, ...Daha fazlası

Dehiscence and fenestration in patients with different vertical growth patterns assessed with cone-beam computed tomography

İLKNUR VELİ | ŞÜKRÜ ENHOŞ

Objective: To test the null hypothesis that the presence of alveolar defects (dehiscence and fenestration) was not different among patients with different vertical growth patterns. Materials and Methods: A total of 1872 teeth in 26 hyper-divergent (mean age: 24.4 6 4.8 years), 27 hypo-divergent (mean age: 25.1 6 4.5 years), and 25 normo-divergent (mean age: 23.6 6 4.1 years) patients with no previous orthodontic treatment were evaluated using cone-beam computed tomography. Axial and cross-sectional views were evaluated with regard to whether dehiscence and/or fenestration on buccal and l ...Daha fazlası
