ABSTRACT:
Instead of prying the crown in the direction opposite to the direction in which it was forced onto its cooperating support tooth, the within crown-removal method calls for initially preparing the crown with a vertically oriented cleave, and then projecting crown-spreading members into the cleave so as to produce an enlargement thereof in its circumferential dimension, with the result that the crown is correspondingly expanded circumferentially and thus is readily disengaged from the tooth.
