Lateral cephalometric radiography is commonly used as a standard tool in orthodontic assessment and treatment planning. The aim of this study was to evaluate the available scientific literature and existing evidence for the validation of using lateral cephalometric imaging for orthodontic treatment planning. The secondary objective was to determine the(More)
PURPOSE The aim this study was to compare the accuracy of orthodontists and dentomaxillofacial radiologists in identifying 17 commonly used cephalometric landmarks, and to determine the extent of variability associated with each of those landmarks. MATERIALS AND METHODS Twenty digital lateral cephalometric radiographs were evaluated by two groups of(More)
OBJECTIVE Facial-type-associated variations in diagnostic features have several implications in orthodontics. For example, in hyperdivergent craniofacial types, growth imbalances are compensated by displacement of the condyle. When diagnosis and treatment planning involves centric relation (CR), detailed knowledge of the condylar position is desirable. The(More)

This work intended to investigate centric slide (CS) on different facial skeletal groups. With this aim in mind, three different groups hyperdivergent, hipodivergent and an intermediate one were studied and compared. The tests performed allowed to identify a statistically more significant vertical displacement in hyperdivergent group while the sagittal(More)
UNLABELLED The Hyoid Bone (HB) is a singular bone with no articulation, but is associated with some vital functions. The purpose of this study was to test the null hypotheses that there is no change in HB position in individuals with vertical jaw dysplasia. METHODS Eleven factors were used to determine the position of the HB. In this paper the ANOVA (two(More)
OBJECTIVE To quantify, for each activation, the effect of preactivations of differing distribution and intensity on the neutral position of T-loops (7-mm height), specifically the horizontal force, moment to force (M/F) ratio, and load to deflection ratio. METHODS A total 100 loops measuring 0.017 × 0.025 inches in cross-section were divided into two(More)
