Changes caused by processing complete mandibular dentures.
Qualitative and quantitative comparisons were made before and after complete mandibular dentures were processed. Linear measurements indicated shrinkage in all dimensions, and the greatest shrinkage occurred in an anteroposterior direction along the lingual flanges. Differences in shrinkage across the various points measured suggest that the denture material twists during curing, and the final qualitative changes appear as pressure areas in the distolingual and anterolabial regions.
