Abstract

Heat cured acrylic resin which is often used as a base for dentures has the disadvantage of being easily broken, the use of flexible denture materials made of nylon thermoplastic has become a new innovation to increase strength. Aim this research to evaluate transversal strength between 1 wt% glass fiber added heat cured acrylic resin and nylon thermoplastic. Thirty two specimens (n=16) with size 65x10x2,5 mm were divided into 2 groups (Nylon termoplastic, and 1 wt% glass fiber added to heat cured acrylic resin). Transversal strength was tested using Torsee’s Electronic System Universal Testing Machine with a load cell of 50 kgf and a test speed of 0.1 mm / second. Statistical data analyzed with unpaired t-test. Results, transversal strength mean value of glass fiber 1 wt% added heat cured acrylic resin was 104,03±9,29 MPa, while nylon termoplastic was 313,89±27,44 MPa. There was statistically significant transversal strength difference between both of groups (p <0.05). Conclusion, It can be concluded that nylon termoplastic had higher transversal strength than 1 wt% glass fiber added heat cured acrylic resin.
