STATEMENT OF PROBLEM Cementation of implant prostheses is a common practice. Excess cement in the gingival sulcus may harm the periodontal tissues. Identification of the excess cement may be possible with the use of radiographs if the cement has sufficient radiopacity. PURPOSE The purpose of this study was to compare the radiographic density of different(More)
This work investigates the performance of cardiorespiratory analysis detecting periodic breathing (PB) in chest wall recordings in mountaineers climbing to extreme altitude. The breathing patterns of 34 mountaineers were monitored unobtrusively by inductance plethysmography, ECG and pulse oximetry using a portable recorder during climbs at altitudes between(More)
Systematic, well-designed research provides the most effective approach to the solution of many problems facing highway administrators and engineers. Often, highway problems are of local interest and can best be studied by highway departments individually or in cooperation with their state universities and others. However, the accelerating growth of highway(More)

PURPOSE To investigate different techniques used by dentists when luting an implant-supported crown and to evaluate the application of cement quantitatively and qualitatively. MATERIALS AND METHODS Participants were given a bag containing cement sachet, mixing pad, spatula, a variety of application instruments, and a polycarbonate crown form. The(More)
Residual excess cement (REC) is a common complication of cement-retained prostheses and has been linked to periimplant disease. Removal of the cement residue may result in resolution of the issue if addressed early in the disease process. However, this is dependent upon the ability to locate and adequately remove the foreign material. This series of patient(More)
Particles created by wear and disintegration of implant materials give rise to foreign body reactions in the tissue surrounding joint endoprostheses. Histiocytes and foreign body giant cells phagocytize the particles released and form granulomas, which lead in turn to remodelling and resorption of the bone at the interface between implant and bone. As a(More)
Stress reactions of the musculoskeletal system may be interpreted as possible precursors of stress fractures. Biological material, in contrast to artificial products, can react in numerous and complex ways. This can not only lead to a continual weakening of the tissue, but also to adaptation phenomena in response to overuse. The causes of such stress(More)
