A dental instrument sharpening system includes an instrument arm for holding a chiral bladed dental instrument and for facilitating movement of at least one of the chiral blades of the dental instrument to a rotatable sharpening stone. A positioning mechanism, coupled to the instrument arm, positions at least one of the chiral blades of the dental instrument in a desired predetermined position. The positioning mechanism includes a clamping mechanism and indexed slotted member. The indexed slotted member has index protrusions, such as protruding nubs, that matingly engage with indentations in the handle of the dental instrument. The handle of the dental instrument includes at least one index indentation such as a conical indentation. The index indentation and the corresponding index protrusion mate to properly position the blade of the dental instrument in a predetermined longitudinal and axial position in the clamping mechanism.
