ABSTRACT:
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.
