  • Tool for adapting a portable lathe to treat the back molar teeth of horses
    Patent number: 4722685
    Abstract: A dental tool for grinding spikes formed on the molar teeth of horses. An elongated hollow tube is fixed to the tool grip, and the grinding bur is removably attached at the other end of the tube to a rotary flexible connector that passes along inside the tube. The length of the tube is approximately the mean depth of a horse's mouth, to enable the tool to access teeth lying well back in the mouth. A detachable cover is provided for the bur, having an opening for exposing the bur to the tooth under treatment and protecting the tongue and cheek tissue from possible injury.
