The present invention is directed towards a dental bur storage device having a plurality of dental bur receiving holes capable of retaining a plurality of different dental bur types having different shank diameters, wherein, each of the plurality of dental bur receiving holes is tapered to allow a retaining fit to be established with any one of the plurality of different dental bur types having different shank diameters. The advantage of using a receiving hole that has a tapered form is that different types of dental burs having different diameters of shanks may be retained by the receiving holes in the dental bur storage device. This allows a wide range of different brands and different types of dental burs to be accommodated on one single dental bur storage device which greatly simplifies the process of selecting a dental bur for a dentist, particularly during a dental treatment. As the receiving hole is tapered, bur shanks of varying dimensions will be received to different depths within the receiving hole to a point where the receiving hole tapers to a diameter substantially equal to the diameter of the shank of the dental bur being received. Moreover, using this type of receiving hole, positive retention of a dental bur may be achieved when the dental bur storage device is handled roughly or inverted. |
