  • Apparatus for aligning a dental drill
    Patent number: 9675425
    Abstract: An apparatus for aligning a dental drill including a guide body having a drill guide through hole including a longitudinal axis, a pair of guide pincer axes orthogonal to and symmetrical about the longitudinal axis and a pair of outer pincer axes orthogonal to and symmetrical about the longitudinal axis, a pair of opposed outer pincers, each outer pincer having an outer engagement protrusion, and each outer pincer is rotatable about a respective one of the pair of outer pincer axes, and a pair of opposed guide pincers, each guide pincer having gear teeth and a guide engagement protrusion, and each guide pincer is rotatable about a respective one of the pair of guide pincer axes. The gear teeth of each guide pincer engage the gear teeth of the other, guide pincer, rotation of one of the pair of guide pincers causes rotation of the other of the pair of guide pincers and the pair of opposed outer pincers rotate independent of each other.
