Abstract:

BACKGROUND: In recent years, clinical applications of injection microwave polymerization have been on the rise. However, reports on its production of denture precision are rarely seen in China and the accuracy needs further verification. 
OBJECTIVE: To evaluate the effect of injection microwave polymerization on accuracy of denture base resin.
METHODS: The study was to compare the difference of denture base resin cured by injection microwave polymerization and water-bath heat polymerization. The dimensional accuracy between the posterior border of upper complete denture and standardized cast at five different positions was measured by digital microscope.
RESULTS AND CONCLUSION: The five posterior border gaps between the upper complete denture and standardized cast were (200±32) μm，(76±13) μm，(69±15) μm，(81±16) μm，(187±27) μm by the injection microwave polymerization, and (243±50) μm, (100±26) μm, (96±30) μm, (109±32) μm, (213±28) μm by the water-bath heat polymerization. There was significant difference between the two groups (P < 0.05). Injection microwave polymerization is better than water-bath heat polymerization on accuracy of denture base resin, and the time that injection microwave polymerization takes is shorter than that by water-bath heat polymerization.
