ABSTRACT
Objective:
To comparative the mechanical properties of f our kinds of denture resin.Method:
The impact strength, f lexural strength, flexural elastic modulus and Brinell hardness of four denture resin materials, Shanghai Shanhu(SH),Shanxi Changzhi(CZ), Luciton 199(LC) and Me liodent(MD), were measured in vitro and the stress-strain curve of each ma terial under flexural force was drawn.Results:
The impact strength(kJ/m 2) of SH,CZ,LC and MD were 9.94?2.25,6.55?1.85,13.76?4.31 and 13.70?3.71; flexural strength (MPa) 75.27?3.24,78.88?7.66,80.47?3.27 and 7 6.72?3.14; flexural elastic modulus(GPa) 3.08? 0.15 ,2.96?0.10,2.63?0.11 a nd 2.56?0.12; Brinell hardness(kg/mm 2)24.15?1.34, 23.43 ? 1.65 ,20.86? 1.26 and 18.49?1.71,respectively.Conclusions:
Comparativ ely speaking, SH and CZ are rigidit and brittle, LC is rigidit and sturdy, MD is tough and sturdy.
