ABSTRACT
This Study Was Conducted To Evaluate The Effect Of Fiber Meshwork Reinforcement On The Fracture Of Maxillary Complete Dentures. Two Groups Of Dentures Were Fabricated. Five Dentures In Each Group. The First Group Had Conventional Non-reinforced Maxillary Complete Dentures. The Second Group Had Fiber-meshwork Reinforced Maxillary Complete Dentures. All Samples Were Individually Mounted On A Computer Controlled Materials Universal Testing Machine, Where Load Was Applied Bilaterally Using T-shaped Load Applicator. Initial Crack Load, Fracture Load And Fracture Pattern Were Recorded For Each Tested Denture. There Was No Statistical Significant Difference In Both Initial Crack And Fracture Loads Of Both Groups, On The Other Hand The Fracture Pattern Of The Fiber-meshwork Reinforced Group Was More Favorable And Less Extensive Compared To The Fracture Pattern Of The Non-reinforced Group. In The Clinical Situation, Both Conventional And Fiber-meshwork Reinforced Maxillary Complete Dentures Are Expected To Be Strong Enough To Resist Fracture Under Maximum Biting Forces, With The Fiber-meshwork Reinforced Dentures Having A More Favorable And Less Extensive Fracture Pattern Compared To The Conventional Non-reinforced Dentures.
