Dimensional accuracy of two denture base processing methods

The mucosal surfaces of maxillary complete dentures processed using the SR-Ivocap injection technique and the Lucitone heat-polymerized compression molding technique were compared to a metal master impression to determine if one method of denture processing produced a more accurate denture base. Comparisons were made before and after polishing the prepared bases to determine if changes occur as a result of this procedure. The dental comparator, described by Rupp and others in 1957, was used to compare selected points on the palatal surface of the denture bases. No statistical differences were found in the accuracy of the denture bases processed using either of the two techniques.
