  • Patent number: 5829590
    Abstract: A box for holding a plurality of dental posts and drill bits. The box is formed of a sterilizable material, i.e., stainless steel, and has a pair of end walls, a bottom wall and opposed open sidewalls. A pivotable cover is provided on the box over the bottom wall. A pair of plates are located within the interior of the box and include plural openings therein into which the dental posts and drill bits are extended. When the drill bits and dental posts are in position within the holes in the plates and the box's cover is closed, they are prevented from falling out of the box. The open sides of the box enable the posts and bits to be sterilized within the box by merely placing the box within a sterilizing environment, e.g., within the interior of an autoclave.
