Dimensional Changes of Denture Base for Maxillary Complete Denture Processed with Injection Type Microwave-cured Resin.

The dimensional changes of denture base of mandibular complete dentures following polymerization were measured by using a three-dimensional measurement system. The mandibular complete dentures processed by injection type microwave-cured resin, conventional type microwave-cured resin and heat-cured resin were compared. Within the conditions imposed in the study, the results were as follows:1. The mandibular complete denture processed by three methods showed minor dimensional changes after deflasking at a distance between alveolar ridge of second molars and incisal alveolar ridge compared with that distance between right and left alveolar ridges of the second molars.2. The mandibular complete denture processed by three methods showed minor dimensional changes after deflasking at a distance of second molars and second premolars between right and left alveolar ridges compared with that distance between right and left buccal flanges and lingual flanges.3. The mandibular complete denture processed by heat-cured resin showed minor dimensional changes compared with that processed by injection type microwave-cured resin and conventional type microwave-cured resin after defrasking.4. The denture processed by injection type microwave-cured resin and conventional type microwavecured resin and heat-cured resin showed a gradual dimensional change.
