An instrument for removing a crown by generating a couple of forces between
the occlusal surface of the stump of the tooth and the basal surface of
the crown. The instrument has an indented intermediate portion and a
working part extending from a tapered intermediate portion and a handle.
When inserted in a groove formed at the occlusal part of the stump along a
plane substantially parallel to the occlusal surface of the crown, the
working portion enables, by a physical action, exertion of a couple of
forces between the respective occlusal surfaces of the stump and the basal
surface of the crown. The working part is rotatable integrally and
correspondingly with a rotation of the handle.
