Abstract EN
Background : The most widely used material for fabrication of denture base is poly methyl methacrylate, despite its popularity, the main problems associated with it as a denture base material are poor strength particularly under fatigue failure inside the patient mouth, impact failure outside the patient mouth, which are the main causes for fracture of denture, several studies was done to increase mechanical properties of denture base.
The present study was conducted to evaluate and compare the effect of addition single walled carbon nanotubes in different concentrations to polymethyl methacrylate on some mechanical properties (surface hardness, surface roughness, impact strength and transverse strength).
Materials and methods: Forty eight samples were prepared for pilot study divided into four groups according to the concentrations of singled walled carbon nanotubes (0 %, 0.5 %, 1 % & 1.5 %) added to heat cure acrylic resin, each group was divided into four subgroups according to the tests conducted (Surface hardness, surface roughness, impact strength and transverse strength) and the results obtained were evaluated to determine the concentration of singled walled carbon nanotubes (SWCNTS) that improve the mechanical properties of heat cure acrylic resin to be used to complete our study, so another 80 samples were made divided into two main groups (0 % SWCNTS as control group) and (1.5 % SWCNTS test group) and all the tests were done again.
Results : Impact strength and transverse strength were significantly increased after adding 1.5 % SWCNTS While surface hardness was significantly decreased and surface roughness was non-significantly affected when compared with control group.
Conclusions : Impact strength and transverse strength of hot cure acrylic resin reinforced with 1.5 % SWCNTS were greatly increased.
