Introduction. Class III malocclusions are characterized by a more prominent lower jaw compared to the upper and skeletal dentoalveolar relationship according Angle. In scientific literature, there is small amount of data on morphological characteristics malocclusion in different populations, so justified need examine population Vojvodina. The aim this study was determine malocclusions, compare ...

This study provides quantitative data and information about the variations in branching patterns of aortic arch, normal lengths of BT and trachea, as well as their diameters, in 30 spontaneously aborted human foetuses aged 14– 35 weeks. Among all the foetuses examined, the aortic arches were found to have mainly two kind of variations in its branching pattern, without gender differences. In 53%...

PURPOSE To determine the minimum required guiding catheter length for embolization of various intracranial aneurysms in anterior circulation and to analyze the effect of various patient factors on the required catheter length and potential interaction with its stability. MATERIALS AND METHODS From December 2016 to March 2017, 90 patients with 93 anterior circulation aneurysms were enrolled. T...

The patient is a 69-year-old male with a symptomatic, fusiform distal arch/proximal descending aortic aneurysm extending over 9 cm in length. As demonstrated in the CTscan, the distal arch aneurysm is 5.5 cm diameter with a newly detected symptomatic ventral sac extending to 6 cm in diameter, presenting as a penetrating aortic ulcer (PAU). The ascending aorta is ectatic to 4.5 cm. His risk fact...

This was a retrospective, longitudinal cephalometric and cast study of 29 white patients at pretreatment, posttreatment, and an average of 6 years 3 months postretention. The goal was to assess changes with treatment and retention with the expanding mandibular lingual arch appliance in conjunction with fixed edgewise treatment. Seven mandibular cast measurements were assessed, including arch cr...

Q2. Damon arch form has broader posterior width than Ortho Form II. Compared to the self-ligating system group (Damon arch form used), conventional system group (Ortho Form II used), showed narrower posterior width as the shape of their arch form, and also had longer arch length and depth. Because the arch dimensions of the two groups were similar before treatment, it can be interpreted that th...

for treating an impacted, dilacerated maxillary central incisor in the mixed dentition. A new fixed appliance promotes proper sagittal and vertical traction of the incisor into the dental arch, while maintaining the patient’s periodontal health and preserving root length. The appliance is an .040" stainless steel fixed lingual arch, soldered to the lingual surfaces of the maxillary first molar ...

Mandibular fractures are frequently encountered in oral and maxillofacial surgery. Open reduction and internal fixation (ORIF) is one of the treatments of choice (1-3). Maxillomandibular fixation (MMF) is usually performed during surgery (2-5). Recently, an arch bar was reconsidered as a means of providing additional stability to internal fixation in anterior mandibular fractures (1, 5). The ar...

INTRODUCTION This study assessed the three-dimensional changes in the dental arch of patients submitted to orthodontic-surgical treatment for correction of Class II malocclusions at three different periods. METHODS Landmarks previously identified on upper and lower dental casts were digitized on a three-dimensional digitizer MicroScribe-3DX and stored in Excel worksheets in order to assess th...

Arch shaped microelectromechanical systems (MEMS) have been used as mechanical memories, micro-relays, micro-valves, optical switches, and digital micro-mirrors. A bi-stable structure is characterized by a multivalued load deflection curve. Here, the symmetry breaking, the snap-through instability, and the pullin instability of a sinusoidal shaped MEMS under static and dynamic electric loads ha...
