Abstract
An abrading body ( ) for treating tooth crowding, which can be introduced into interdental spaces ( ) between teeth ( ) and is provided with oppositely disposed working or abrading surfaces ( ) on both sides thereof and a shaft for attachment to a reciprocating drive mechanism ( ). The abrading body ( ) can be introduced vertically between the teeth ( ), i.e., in the longitudinal direction thereof, and is designed to carry out an abrading movement in this direction. The abrading surface ( ) is formed with a convex cross-sectional configuration. The opposite abrading surface ( ) is formed with a concave cross-sectional configuration. The radius (R ) of the convex abrading surface ( ) is greater than the radius (R ) of the concave abrading surface ( ). An advantageous interdental contact in the form of an overlapping, dimeric, arcuate chain of teeth can be created by introducing concave and convex contact surfaces on adjacent teeth using the tooth abrading body ( ) of the invention.
