It had been the impression of members of the Department of Orthopedics at Yale that diaibetes mellitus was found in cases of fractured femoral neck more frequently than in cases of intertrochanteric fractures of the femur. Should such an impression be borne out by fact, some significant feature of metabolism in relation to these fractures might be brought to light. It was speculated as to wheth...

BACKGROUND AND AIMS Several products have been marketed for disinfecting impression materials. The present study evaluated the effect of Deconex, Micro 10, Alprocid and Unisepta Plus sprays on Staphylococcus aureus and Candida albicans transferred to alginate and polyvinylsiloxane impression materials. MATERIALS AND METHODS A total of 180 impressions of a maxillary model (90 alginate and 90 p...

abstract statement of the problem: dental prosthesis is usually made indirectly; therefore dimensional stability of the impression material is very important. every few years, new impression materials with different manufacturers’ claims regarding their better properties are introduced to the dental markets which require more research to evaluate their true dimensional changes. objectives: the ...

Background. Addition silicones are popular as dental impression materials and are used in bite registration procedures. Objective. This study aimed to compare the postsetting elasticities and other mechanical properties of thirteen addition silicone interocclusal recording materials. Materials and Methods. The following materials were investigated: Colorbite D, Futar D, Genie Bite, Jet Blue Bit...

A product available commercially for making dental impressions, Jeltrate Plus, was evaluated as a tissue equivalent bolus material. Jeltrate Plus was found to be tissue equivalent in 6 and 15 MV photon energy beams and 6, 12, and 20 MeV electron energy beams. As a first step, different preparations for making the bolus material were investigated and an optimal mixture was determined to be two p...

The ultimate capacity of a novel type piled foundation called an ‘impression’ pile has been investigated using centrifuge modelling techniques. name derives from the small discrete impressions created in side walls bored cast situ to increase soil/pile friction such that form nodules on shaft concreted pile. technology is suitable for piles overconsolidated clay, as London Clay. experiments exp...

Accurate impression is a main requirement for obtaining passive fit of restorations. The aim of this case report is an alternative technique in using closed-tray impression posts for open-tray impression technique for exemplification at a patient that can have limited interocclusal vertical space. After osseointegration, 7 implants examined in edentulous maxilla, open-tray impression technique ...

Impression management strategy is an important way to cope with the stigma of failed entrepreneurial firms. However, most existing studies only focused on process impression a single strategy. Few have provided systematic theoretical explanation how use different types strategies stigma. To fill this gap, two-path model failure was constructed, based two-component management. In addition, mecha...
