  • Dental instrument sharpening system
    Patent number: 5700184
    Abstract: 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.

  • Method and device for sharpening chiral blades of dental instruments
    Patent number: 5331774
    Abstract: A device for sharpening a dental instrument has a housing with a clamp movably mounted on the housing. The clamp fixes a dental tool in a holding device at a predetermined position. The dental tool is then sharpened on a fixed, but rotatable sharpening stone. The precision sharpening device includes at least one vertically fixable tool holding mount, and at least one fixed holding post to permit the tool holding mount to rotate horizontally to the sharpening stone.
