OBJECTIVE This study was aimed to evaluate the perception of orthodontists and of lay people about the facial profile and its possible correlation with cephalometrics parameters. MATERIALS AND METHODS A total of 20 evaluators were divided into two groups (10 orthodontists and 10 people with no relation to such area - lay people). They were asked to evaluate the photographs of 25 young males a...

Background and objective: A deep bite malocclusion may be due to skeletal dental factors. The analysis of the etiological factors have an influence on treatment plan. aim this study was exploration most common that contribute in Yemeni individuals, as well correlations between them. Material methods: a cross-sectional prospective conducted evaluate 136 individuals with bites using casts lateral...

Objective Evaluate the correlation between Friedman Tongue Position (FTP) and airway cephalometrics in patients with obstructive sleep apnea (OSA). Study Design Retrospective review of adult patients with OSA undergoing Cone Beam Computed Tomography (CBCT). Methods Collected data included age, sex, body mass index, apnea hypopnea index, FTP, and airway cephalometric parameters. Data analyse...

OBJECTIVES Accumulating evidence has shown that there is a genetic contribution to obstructive sleep apnea (OSA).The objectives were to use magnetic resonance imaging (MRI) cephalometry to (1) confirm heritability of craniofacial risk factors for OSA previously shown by cephalometrics; and (2) examine the heritability of new craniofacial structures that are measurable with MRI. DESIGN A sib p...

BACKGROUND Manual annotation of landmarks is a known source of variance, which exist in all fields of medical imaging, influencing the accuracy and interpretation of the results. However, the variability of human facial landmarks is only sparsely addressed in the current literature as opposed to e.g. the research fields of orthodontics and cephalometrics. We present a full facial 3D annotation ...

Introduction: In orthodontics, cephalometrics plays a key role in diagnosis and treatment planning. Cephalometric radiograph is the product of a two-dimensional image of the skull in lateral view, which helps in enabling the relationship between teeth, bone, soft tissue, and empty spaces in horizontal and vertical planes of space. It also helps in evaluation, diagnosis, treatment results, and p...

Traditional cephalometrics (1-3), though having the limitation of any two-dimensional (2D) method, has several advantages, including low cost, easy access and reduced invasiveness. Although computerized tomography (CT) has many advantages as a measuring tool for three-dimensional (3D) airway size (4-8), it is time consuming and expensive for· routine clinical use. However, 3D color reconstructi...

BACKGROUND The porion (Po) is used to construct the Frankfort horizontal (FH) plane for cephalometrics, and the external auditory meatus (EAM) is to transfer and mount the dental model with facebow. The classical assumption is that EAM represents Po by the parallel positioning. However, we are sometimes questioning about the possible positional disparity between Po and EAM, when the occlusal ca...

BACKGROUND/AIM Functional appliances can be used effectively in the treatment of skeletal Class II/1 malocclusions. The best treatment results are obtained during active period of facial growth when skeletal, as well as dentoalveolar, changes occur. In comparison with removable functional appliances, such as activator, that are effective only during adolescent period of growth, the Herbst fixed...
