PURPOSE The purpose of this study was to investigate the marginal precision of computer numeric control-milled frameworks fabricated of grade 4 commercially pure titanium or cobalt-chrome alloy through digital technology and to compare them with conventional cast frameworks. MATERIAL AND METHODS A titanium cast of a mandibular arch with six implant analogs was used as a master. The master cas...

N europathic plantar ulcers are classical lesions secondary to diabetic polyneuropathy (1,2). The worldwide gold standard treatment is the nonremovable off-loading cast (3–5). However, the device is not widely used due to concerns related to risk factors of the off-loading cast (i.e., joint rigidity, additional ulcer formation beneath the cast, and infection of the ulcer enclosed in the cast). ...

BACKGROUND A fiberglass short arm cast can be used to treat a distal radial fracture, but posttraumatic edema may lead to excessive cast tightness and resultant soft-tissue injury. We sought to quantify a simulated edema-induced pressure within a fiberglass short arm cast and to determine the effectiveness of different cast-cutting methods for pressure reduction. We hypothesized that cast cutti...

We assessed the unloading effect of the patellar tendon-bearing (PTB) cast in five healthy volunteers using a new system for analysis of dynamic plantar pressure. We devised a method to improve the unloading effect of the PTB cast, and tested this using the same system. Our findings showed that the conventional PTB cast only achieved unloading of 30% of the body-weight and that the part of the ...

1 Overview Motion perception is an amazing innate ability of the creatures on the planet. This adroitness entails a functional advantage that enables species to compete better in the wild. The motion perception ability is usually employed at different levels, allowing from the simplest interaction with the 'physis' up to the most transcendental survival tasks. Among the five classical perceptio...

We introduce a new notion of conditional oblivious cast (COC), which involves three parties: a sender S and two receivers A and B. Receivers A and B own their secrets x and y, respectively, and the sender S holds the message m. In a COC scheme for the predicate Q (Q-COC), A and B send x and y in a masked form to S, and then S sends m to A and B such that they get m if and only if Q(x, y) = 1. B...

Casting is a routine procedure used for fracture care in the pediatric population. The purpose of this review is to provide pearls and pitfalls that our institution has learned from previous literature. When applying the cast, we recommend using cotton padding for the liner and fiberglass or plaster depending on how much swelling is expected. A well-molded cast must be applied in order to preve...

Previous studies have demonstrated that the perception of shading is based upon assumptions about lighting direction, for example, light from above. However, it is not clear whether these assumptions are used in the perception of cast shadows. Moreover, it is unclear whether a perceptual interaction exists between shading and cast shadows because until now they have been studied separately. In ...

Background: Anxiety following casting is an unrecognised complication that results in frequent visits to fracture clinic in the UK. There is a paucity of research regarding this complication. Failure to recognise Cast Anxiety (CA) leads to increased visits, frequent cast changes and possible failure of treatment despite no objective problems with the cast. Prior research has suggested a possibl...
