ABSTRACT:
A miniature motorized hand held dental saw wherein the axis of rotation of the handle of the dental saw is tangent to the cutting edge of the blade. This important characteristic, combined with the use of a flexible blade, enables the operator to change, as needed, the direction of the cut without any snagging or binding effects. The dental saw preferably includes a main steel body on which are attached three flanged Teflon.TM. coated bearings that support and guide a thin, annular blade. The rotation of the blade, on these flanged bearings, is created by a drive assembly including two opposite wheels, a drive wheel and a follower wheel, each wheel including a hub on which is fitted an o-ring. The opposite o-rings create an equal pressure on both faces of the blade and cause the blade to rotate.
