Abstract:
A method for treating tooth crowding said method comprising:providing an abrading body having two sides with oppositely lying working surfaces, said abrading body having a connector for attachment to a reciprocating drive mechanism, wherein one working surface has a convex cross-sectional shape having a radius of curvature R3, and the other working surface has a concave cross-sectional shape having a radius of curvature R2, wherein the radius of curvature of the convex working surface is greater than the radius of curvature of the concave working surface and abrading the surface of multiple teeth vertically with said abrading body to produce concave and convex interdental contact surfaces between multiple teeth to produce an overlapping dimeric arcuate chain of teeth wherein said abrading body simultaneously abrades the surface of adjacent teeth to produce concave and convex interdental contact surfaces wherein both working surfaces of said abrading body are coated with an abrasive.
