It is proposed to use elastomeric composites as artificial joint bearing surfaces to increase their fluid film lubrication and therefore reduce the number of failures which have been attributed to wear mechanisms related to frictional forces. The fluid generated between the surfaces supports part of the load and prevents direct contact of the bearing surfaces. In order to obtain optimum elastoh...

This study was carried out to measure the dimensional changes in silicone impression material, which can affect the fitness of the prosthesis. Using both single and double mix techniques, 20 impression samples for each of 3 different proprietary silicones, Xantopren-H, President and Fulldent, were made. Selected measurements were made on the stone casts made from each impression. In all 3 cases...

Objective: This case report aims to introduce the black triangle therapy in Miller’s Class IV gingival recession. Methods: The patient complained of spacing between upper and lower teeth causing food accumulation, “long teeth”, receding gums which were unaesthetic during speaking. Clinical examination maxillary mandibular anterior revealed Miller recession, large triangles, no tooth mobility no...

This paper describes optical components prepared using poly(dimethylsiloxane) elastomers and liquid metals as constituent materials. Most optical components are fabricated from rigid materials such as glass, rigid polymers, or metals. By contrast, the elastomeric optics described here are designed to be deformable. Because the structure of the optical surface can be deformed easily, a single el...
