Abstract
A newly made gold crown on a second molar may open the incisal guide pin of the articulator when placed on its die in the master cast. If the incisal pin opening is 1.5 mm, the amount of occlusal adjustment required on this second molar crown is less than 1.5 mm. The purpose of this geometric study was to determine the opening at the second molar and the incisal edges with a given opening at the incisal guide table.
