Abstract: A dental saw blade is provided and includes a body having a first face and an opposing second face and a cutting edge and a central opening for receiving a drive component for rotating the blade. The blade has a region of abrasive material disposed on each of the first and second faces to define a cutting zone at an outer section of the face and further has a means for stiffening the body and reducing binding of the blade during a cutting operation. The means is disposed between the cutting zone and the central opening and includes features that are formed on each of the first and second faces.

Abstract: A dressing unit for advancing and retracting a spindle, having a diamond roll rotatably mounted thereon, wherein advancement of the spindle brings the diamond roll into contact with a grinding wheel for dressing the grinding wheel. The dressing unit comprises an outer ram mounted within a housing, an inner ram telescopically disposed within the outer ram, means for advancing and retracting the outer ram to a positive stop, and means independent of the advancing and retracting means for incrementally moving the inner ram from an inner position to an extended position. The inner ram is connected to the spindle to advance the spindle to thereby bring the mounted diamond wheel into contact with the grinding wheel.
