[Effect of thermal expansion on the accuracy of fit of cast crowns].
Extent and direction of dimensional changes in the finished cast crown resulting from the thermic expansion of the wax model are determined as a function of the time the crown was subjected to tempering as a function of tempering temperature. Expansion of the wax model does not come up to the expectation of preventing a reduction of the cast object.
