Abstract

Background: The potential alternative materials to PMMA are the polycarbonates and the nylon denture base resins. Of this nylon is the generic name for certain types of thermoplastic polymers belonging to the class polyamides. This study had compared between conventional and thermoplastic complete denture base materials regarding maximal voluntary biting force and masticatory efficiency of the patient. Method: Ten completely edentulous patients received both types of dentures respectively. Each patient was allowed to wear each set of dentures for six months during which bite force of each side and masticatory efficiency (with three test foods; carrots, peanuts and banana) were measured at one week, three months and six months intervals. Results: Independent t test was used for the statistical analysis. There were no remarkable variances between the two types of denture bases as P-value >0.05. Conclusion: The results of this study showed there were no significant differences in biting force and masticatory efficiency between conventional and thermoplastic polyamide complete dentures during this period. Key words: acrylic denture, flexible denture, bite force
