Changes in vertical dimension of occlusion in conventional and microwave processing of complete dentures.

An investigation was made to compare the increase in vertical dimension of occlusion in complete dentures after processing with conventional and microwave procedures. Lucitone-characterized denture base material was used for 15 sets of complete dentures cured conventionally. Justi-characterized acrylic resin and microliquid were used for 15 sets of complete dentures cured by the microwave procedure. The results of the study showed increases in vertical dimension of occlusion in both methods under 1 mm, which is considered technically acceptable. However, a statistically significant larger increase was present in the microwave technique.
