Intra-oral appliances such as transpalatal arch and Nance appliance fail to resist against forces that tend to loosen the anchorage. The infirmity arises due to the long lever arm and the mesial force that is perpendicular to the long axis of the appliance. The butterfly arch is presented here as an intra-oral appliance that withstands the mesially directed forces with a mechanism that puts str...

Like finger prints each individual has a unique dental arch form design. Recording patient's dental arch form may be required in various fields in dentistry be it longitudinal studies for evaluating growth, forensic dentistry and most importantly in orthodontic practice for fabricating arch wires for individual patients. An easy and practical method to obtain individual arch form for each patie...

Plantar fasciitis is characterised by pain involving the medial calcaneal tubercle that is exacerbated after periods of nonweightbearing (Tountas & Fornasier, 1996). Although the pathogenesis is poorly understood, lower limb biomechanics or foot types that result in a lowered and elongated medial longitudinal arch have been widely cited as causal factors in the development of the condition (Cor...

background : the concepts of ‘intelligence’ and ‘intellectual performance’ though seem alike, but are different. intelligence assessment of an individual is technical, is done by the application of multiple, reliable and validated, iq (intelligence quotient) tests on the same individual in different settings (date, place and time). however, ‘intellectual performance’ (ip) has a reference only t...

Bovine aortic arch refers to the most common variant of aortic arch branching in humans. This configuration can be found in approximately 27% of the population and can be further divided into 2 subtypes. In the less usual subtype (7%, Figure 1 – panel A), the innominate artery (usually 1-2.5 cm long) trifurcates into the left common carotid artery, the right common carotid artery and the right ...
