Flexural Strength Of Heat Cure Denture Base Resin With Addition Of Aluminium Oxide Filler Cured By Different Curing Methods
Journal Title: National Journal of Medical and Dental Research - Year 2018, Vol 6, Issue 4
Abstract
Background:Flexural strength of denture base resin is considered primary mode of clinical failure. Aim:This study was done to compare the flexural strength of acrylic resin with or without addition of aluminium oxide filler and processed with two techniques. Material and method:10 samples each were processed using normal acrylic resin with conventional water bath technique, modified acrylic resin with 10% and 15% aluminium oxide processed by conventional water bath technique, normal acrylic resin with microwave technique, modified acrylic resin with 10% and 15% aluminium oxide processed with microwave technique. The values obtained were subjected to statistical analysis using ANOVA followed by post hoc Tukey’s test. Result:Mean flexural strength were normal acrylic resin processed with conventional water bath technique is 68.2, Modified acrylic resin with 10% aluminium oxide processed by conventional water bath technique is 78.11, Modified acrylic resin with 15% aluminium oxide processed by conventional water bath technique is 82.95. Normal acrylic resin processed with microwave technique is 79.43. Modified acrylic resin with 10% aluminium oxide processed with microwave technique is 82.21. Modified acrylic resin with 15% Al2O3 processed with microwave technique is 85.27. Conclusion: The specimens of heat-curing acrylic resin reinforced with 10% and 15% aluminium oxide filler provided superior flexural than those with normal acrylic resin. The specimens of heat curing acrylic resin reinforced with aluminium oxide filler showed increase in flexural strength when processed by microwave technique.
