Patent ID: 11779435

Abstract:
The disclosure relates to a dental screwdriver having a shaft portion made of a smart type alloy that bends with little or no resistance along an arch forming portion thereof and without imparting torqueing forces along a distal front end portion thereof onto which is connected a drive tip designed to interface with an appropriately sized screw. The smart alloy automatically assumes its original shape in the absence of twisting forces on the shaft along the arch forming portion. In an alternate embodiment, assuming the original shape involves applying heat and/or subtle finger pressure. The dental screwdriver may be part of a set of screwdrivers, each having a distal front end portion which is uniquely weighted, sized and/or dimensioned to accommodate different driver tips, handle different torqueing functions, and/or configured to bend to a specific maximum angular arch without permanent deformation. A dental prosthetic having a curved bore cavity is also described.
