title: [The Centric relation. II. Volumetric variations during the mounting of models on the articulator].
abstract: When mounting models on the articulator there is some possibility of error due to the expansion of plaster during the setting period. If one does not pay attention to this expansion, one can observe an opening in between the arms of the articulator. In order to minimize expansion one must: -- increase the W/P ratio -- decrease the amount of plaster used for mounting the models The expansion modifies the reference plane and this is important only in case of remountings.
