Objective.
The aim of this study was to evaluate the effect of incorporation of glass fiber, zirconia, and nano-zirconia on the transverse strength of repaired denture base.
Materials and Methods.
Eighty specimens of heat polymerized acrylic resin were prepared and randomly divided into eight groups ( n = 10 ): one intact group (control) and seven repaired groups.
One group was repaired with autopolymerized resin while the other six groups were repaired using autopolymerized resin reinforced with 2 wt% or 5 wt% glass fiber, zirconia, or nano-zirconia particles.
A three-point bending test was used to measure the transverse strength.
The results were analyzed using SPSS and repeated measure ANOVA and post hoc least significance (LSD) test ( P ≤ 0.05 ).
Results.
Among repaired groups it was found that autopolymerized resin reinforced with 2 or 5 wt% nano-zirconia showed the highest transverse strength ( P ≤ 0.05 ).
Repairs with autopolymerized acrylic resin reinforced with 5 wt% zirconia showed the lowest transverse strength value.
There was no significant difference between the groups repaired with repair resin without reinforcement, 2 wt% zirconia, and glass fiber reinforced resin.
Conclusion.
Reinforcing of repair material with nano-zirconia may significantly improve the transverse strength of some fractured denture base polymers.
