The effect of the Twin Block functional orthodontic appliances is mostly dento-alveolar with small skeletal effect. There are certain clinical indications where functional appliances can be used successfully in class II malocclusion e.g. in a growing patient. The use of these appliances is greatly dependent on the patient's compliance and they simplify the fixed appliance phase. In this case, a...

The incidence of congenital atrioventricular (AV) block is estimated to be about 1 in 15,000-20,000 births. Although it is a rare disease, it increases fetal, neonatal, and childhood morbidity and mortality, and 60%-65% of all cases are reported to require pacemaker implantation before reaching adulthood (1). This disease can be idiopathic, but it is mostly caused by transmission of auto-antibo...

This cephalometric study evaluated skeletal and dentoalveolar changes induced by the Twin-block appliance in 2 groups of subjects with Class II malocclusion treated at different skeletal maturation stages in order to define the optimal timing for this type of therapy. Skeletal maturity in individual patients was assessed on the basis of the stages of cervical vertebrae maturation. The early-tre...

In order to become a mega hub port, major ports all over the world are making every effort to enhance their productivity through efficiency of internal operation. Accordingly, in order to enhance the competitiveness of a container terminal, an automated container terminal is considered as the best alternative. An automated container terminal is using such automated handling equipment as AGV (Au...

Objective: Recent years have witnessed a renewed interest to determine a quantifiable relationship between mandibular advancement performed with an orthodontic appliance and the resulting airway dimensions and volume. The study was conducted to evaluate the changes in dimensions of pharyngeal airway space using computed tomography (CT) in Class II division 1 patients with retrognathic mandible ...
