introdouction: the aim of this study was to compare information regarding pharyngeal airway sizes in adolescent subjects with different malocclusion classes obtained from lateral cephalograms and 3–dimensional (3d) cone-beam computed tomography (cbct) scans. materials and methods: in this prospective cross-sectional study, cbct scans and lateral cephalograms of 35 subjects, taken within one wee...

OBJECTIVES We aimed to compare the standard methods of cephalometry and two-dimensional photogrammetry, to evaluate the reliability and accuracy of both methods. MATERIAL AND METHODS Twenty-six patients (mean age 25.5, standard deviation (SD) 5.2 years) with Class II relationship and 23 patients with Class III relationship (mean age 26.4, SD 4.7 years) who had undergone bilateral sagittal spl...

The evaluation and measurement of human body dimensions and diameters are achieved by physical anthropometry (Chamella, 1997; Williams et al., 1995). The dimensions of newborns bodies can be the basis for all changes in anthropometric indices. Therefore, these dimensions are important in this field, because this is one of the health evaluation indices of newborns (Golalipour et al., 2000; Afak ...

To analyze changes in the soft tissue profile associated with an inverted L osteotomy, preoperative, early postoperative, and late postoperative lateral cephalographs of 13 children with craniofacial microsomia (mean age 9 +/- 2 years) were scanned, and 11 soft tissue landmarks were digitized (digitization errors insignificant; P > 0.05). Cephalometry, Euclidean distance matrix analysis (EDMA),...

OBJECTIVE The combination of generalized Procrustes superimposition (GPS) and principal component analysis (PCA) has been hypothesized to solve some of the problems plaguing traditional cephalometry. This study demonstrates how to establish the currently unclear relationship between the shape space defined by the first two principal components to the ANB angle, Wits appraisal, and GoGnSN angle,...

Basic studies and researches on craniofacial growth show that occlusal plane changes its position in space and time during the whole period of development and growth of the skull until the attainment of the mature dentition stage. The purpose of this retrospective study is to evaluate the inclination of the gnatological occlusal plane related to the axio-orbital plane and their relations with s...

A cephalometric study of 70 Assamese young adults (35 male and 35 female) within age range of 18 – 25 years with acceptable profile and occlusion was carried out by means of the Steiner’s analysis. The purpose of the study was to establish skeletal & dental parameters for Assamese young adults using Steiner’s analysis, evaluation of variability between male & female Assamese normal occlusion su...

Planar cephalometry in essence provides only 2D information. CT scan provides 3D information for osseous and soft tissues but remains irradiant. STL dental models are interesting tools allowing for the production of 3D printed surgical splints. In orthognathic surgery planning, exploiting these three fields of information by linking them to the clinical findings and getting them all synchronize...

Biometric comparison procedures for dental imaging methods with continuous outcome were reviewed, mainly concentrating on assessment and comparison of accuracy and precision according to the study design. Univariate graphical and numerical representations of corresponding deviations were summarized to derive a 'check list' of minimum information necessary to compare the measurement methods. The...
