Abstract
Purpose: The purpose of this study is to evaluate the fitness of lower jaw compete denture with glass fiber.
Methods: Lower jaw edentulous model was selected as the master model. Ten study models were produced using Type Ⅳ stone(n=10). Lower jaw trial dentures were produced by the wax denture base and artificial teeth. Conventional complete denture (CD) group was fabricated by excluding glass fiber reinforcement (n=5). Glass fiber complete denture (GD) group was fabricated with glass fiber reinforcement (n=5). The lower jaw trial complete denture was invested using a plaster. PMMA resin was injected and curing was performed. The CD and GD groups measured the fit using silicone replica technology. The measured data was verified by t-test.
Results: The anterior area of the CD group showed the smallest value. There was a statistically significant difference in the anterior area of the CD group and the GD group (p<0.05), but there was no statistically significant difference in the posterior area (p>0.05).
Conclusion : Complete denture with glass fiber showed low fitness and further study is needed to apply it clinically.
