Abstract
A dental reamer having one or more cutting sections and one or more spiral grooves. The dental reamer has at least one cutting edge having a cutting point, characterized in that a tangent to the cutting point tends to superimpose itself on a tangent to a diameter of a circle in which the cutting sections are inscribed, wherein the diameter passes through the cutting point. The invention provides a reaming cut that, in a surprising manner, reduces or even eliminates the spiral displacement (i.e., uncontrolled advancement of the reamer) that results from rotation of the prior-art reamers, while still maintaining an excellent reaming efficacy.
