Pressure Transmission under Thermoplastic Nylon Denture Base Using Acrylic and Porcelain Denture Teeth

摘要

The purpose of this study was to evaluate pressure transmission under thermoplastic nylon denture base using acrylic and porcelain denture teeth. Mandibular right first molar acrylic denture teeth (Bioeco) and porcelain denture teeth (SMIC) embedded on 15x15x3mm3thermoplastic nylon (TCS) as denture base were evaluated (n=16). A 100N force was applied on the specimen using universal testing machine and the pressure transmitted under the specimen was observed using pressure transducer. Data were statistically analyzed with Univariat test and followed by Mann-Whitney test (P<0.05) since the data were not normally distributed. Porcelain denture teeth showed significantly higher pressure transmission than acrylic denture teeth (P<.001). There was a significant difference of pressure transmission under thermoplastic nylon denture base using acrylic and porcelain denture teeth.
