For a number of years, prosthetics research groups have been attempting to develop a method of forming sockets directly on amputation stumps, in order to reduce the time required to produce a satisfactory socket and to eliminate the messy working conditions inherent in the use of plaster of paris (1). Direct forming requires a material that: (a) is plastic at temperatures moderately above ambie...

In electroosmotic dehumidification, a membrane composed of a desiccant material removes moisture from air to be conditioned. Then, electroosmotic pumping driven by the application of voltage moves the moisture across the membrane and rejects it on the other side. A bench top experiment was developed to screen promising membrane materials. Two sealed humidity chambers were separated by a membran...

Pressure on the sole of the foot inside three different types of plaster cast, used in treatment of fracture of the lower leg, was measured on six normal persons. No significant difference was found between these pressures in below-knee plaster, full length plaster including the thigh and patellar-tendon-bearing plaster. Only occasionally a relief in pressure was found in patellar-tendon-bearin...

OBJECTIVES To compare traditional plaster casts, digital models and 3D printed copies of dental plaster casts based on various criteria. To determine whether 3D printed copies obtained using open source system RepRap can replace traditional plaster casts in dental practice. To compare and contrast the qualities of two possible 3D printing options--source system RepRap and commercially available...

Aim: To assess the physical and mechanical properties of plaster of Paris (POP) bandage cast used as a splinting and casting materials. Materials and Methods: POP casts were divided into three Groups A, B and C with 2, 3 and 8 layer for POP bandage, respectively (n=6 in each group). Handling characters, technical easiness or difficulties, setting time, weight, diameter and thickness of the cast...
