Abstract

Introduction: Acrylic resin is the most common material for the denture base because acrylic resin has good esthetics, ease of processing, reparability and inexpensive. A disadvantage of acrylic resin is that it is easily to be cracked. One of the ways to resolve this problem is by adding the agave sisalana fiber and E-glass fiber. The purpose of this study was to find out the effect after addition agave sisalana fiber and E-glass fiber on impact strength of an acrylic resin denture plate reparation. Material and Method: The experiment involved twenty seven plates of heat-cured acrylic with the dimensions of 55x 10 x 10 mm with the 26 x 5 x 4 mm for the cavity to measure, each measurement divided into three groups, with nine samples for each groups. The first group as a control group (without fiber), the second group as a group with agave sisalana fiber addition, the third group as a group with e-glass fiber addition. All plates were soaked in distillation water for one day at 37^oC. Plates were tested for impact strength using the charpy method. All data obtained was analyzed with one-way ANOVA followed by LSD (Least Significant Difference) with p<0,05. Result and Discussion: The result showed that the influences of impact strength between without fiber with agave sisalana fiber and E-glass fiber addition on acrylic denture reparation. Acrylic denture reparation in both fibers with concentration 3,3%, agave sisalana fiber has the highest impact strength rather than e-glass fiber. Conclusion: The conclusion of this study is that there is an increase in impact strength with agave sisalana fiber and E-glass fiber addition on acrylic denture reparation and agave sisalana fiber has the highest impact strength.
