Dental displacement in complete dentures influenced by different flask types and polymerization cycles

Abstract This study evaluated the dental displacement in dentures included different flasks and processed by Australian cycle modified or microwave. Metal pins were placed on teeth as reference for measurements: a) Incisal edge of maxillary mandibular central incisors, buccal cusp vestibular first premolars, mesiobuccal cusps second molars; b) Incisor to incisor, premolar molar molar; c) Left incisor left right molar, d) Vertical. Dentures divided according (n=10): G1- Metal; G2- HH bimaxillary metal; G3-Microwaves; G4- microwaves. For G1 G2, polymerization at 65ºC/30 min, flame quenched 30 heating boiling water 1 h. G3 G4, microwave (20 min/140 W 5 min/560 W). Comparator microscope with digital camera analytical unit assessed measurements before after denture polymerization. The final distance was made subtracting processing from processing. value difference submitted 2-way ANOVA, considering flask type type. Maxillary showed greater when compared denture. Flask types interaction similar between In conclusion, promoted cured cycles effect teeth. Greater occurred
