Occlusal changes in complete dentures processed by pack-and-press and injection-pressing techniques.
Ten pairs of stone casts were mounted in an articulator using a standardized maxillomandibular relation, on which trial dentures were constructed. Two groups were established: GI- pack-and-press technique; GII- injection-pressing technique. Intermaxillar contacts were marked and counted, and the contact between incisal pin and incisal table was measured, before and after the processing. The average contact loss after the processing was 37.85% (GI) and 20.8% (GII). The average incisal pin opening after the processing was 1.3mm (GI) and 0 (GII). Data differed statistically (Mann-Whitney's test, p < 0.05). The injection-pressing system was superior according to contact loss and incisal pin opening.
