摘要： Improved tensioning or preloading of screws used to assemble dental implants is made possible by using screws which have a coating of gold, particularly screws made of palladium alloy or of titanium or a titanium alloy which has been plated with a different biocompatible metal, such as platinum, nickel or copper. The increased preload improves the stability of the dental implant assembly because greater mastication forces are then required to pry apart contiguous components of the implant assembly and bend the screws.

摘要： A construction material adapted for a wide variety of uses is shown, as, for example, in repairing cracks, holes and dents in the hulls and bodies of boats and land vehicles, leaks in gas and liquid conduits such as exhaust pipes and water pipes, and leaks in gas and liquid tanks and other containers; repairing fractured poles, booms, spars, antennas, and the like, and strengthening similar structures that are not fractured; patching roofs, gutters, and drainpipes; sealing leaking containers of pressurized fluids, such as air-conditioning systems, swimming pools, and hydraulic hoses; and electrically insulating all manner of articles. The product comprises a flexible web impregnated with a pliable mastic in a sealed package which maintains its contents in stable soft and pliable condition until opened, after which the web is applied to the use intended and the mastic begins to harden in place upon exposure to water, or to only the moisture in the air. The mastic is able to harden and cure under water, salt or fresh.
