a compressive strength of 2,200 psi and the other with a compressive strength of 3,500 psi, were the most satisfactory for cementing temporary restorations. The data collected, however, were not sufficient in quantity to differentiate between the two cements. There was the possibility that one or the other of the two cements might prove superior, and this investigation was undertaken to collect...

Large vibrating plates are used as thunder sheets in orchestras. We have extended the use of flat plates by cementing a flat panel electroacoustic transducer on a large brass sheet. Because of the thickness of the panel, the output is subject to nonlinear distortion. When combined with a real-time input and signal processing algorithm, the active brass plate can become an effective musical inst...

Third generation cementing technique is now commonly used for total hip arthroplasty. The aim of this technique is to sufficiently pressurise the cement and allow maximal penetration of the cement into any remaining trabecular bone to provide a stable fixation of the prosthesis. We report a case where this pressurisation resulted in polymethylmethacrylate retrograde filling of the nutrient vess...
