Özet:

 

In removable  prosthodontics, poly(methyl methacrylate) (PMMA) is the  most suitable for the construction of denture bases. Intra-orally, the subjected stress intensity during the function accelerate  the fracture of acrylic resin denture bases. Extra-orally, fracture occurs when dentures are accidentally dropped on a hard surface. The aim of the current study was to  investigate the effect of coupling agent concentration on the mechanical properties of Hydroxyapatite/Poly(methyl methacrylate) (HA/PMMA) denture base  composite. The Hydroxyapatite (HA) treated with four different ratios (i.e. 0, 5, 7 and 10 wt%) of 3-(trimethoxysily) propyl methacrylate (γMPS) silane coupling agent was added into the PMMA matrix. The mechanical performance of the composite was evaluated by conducting fracture toughness, flexural  and  tensile  tests.  An  improvement  of  13.83%  and  9.62%  in  the  tensile  and  flexural  strength respectively, was achieved. The tensile and flexural modulus of the composite increased by 19.04% and 12.5% respectively. A significant improvement of 29.26% in the fracture toughness was observed at 10 wt% of γ-MPS. 10 wt% of γ-MPS  is  the  optimum  amount  of  coupling  agent  for  obtaining  balanced mechanical properties.
