Abstract:
Objective To study the effect of surface treating methods on the shear strength of Panavia F luting cements to Cercon zirconia.Methods Forty sample disc of Cercon zirconia with 20 mm in diameter and 4 mm in height were prepared.Another 40 sample discswith 5 mm in diameter and 4 mm in height were also prepared Both of the two types of samples were randomly devided into four groups A,B,C,and D in whichdifferent surface treatments were delivered.In group A samples was treated with 600 # sand paper,and in group Bwith sand blasting,and silanization in group C,and sand blasting plus silanization in group D.All samples were bonded with Panavia F luting cement under the aid of glass mould.The value of shear strength was measured and statistically analysed.Results The shear strength of four groups of samples were (21.50 + 1.98 ),(23.68 + 2.31 ),(20.69 ± 1.55 ),(24.01 + 2.19 ) M Pa respectively.The population mean was not equal.There was no significant difference between 600 # sand paper treated group and silanization group,nor between sand blasting group and sand blasting plus silanization group.Conclusions Sand blasting is a effective means to increase the shear strength,and 600 # sand paper treatment and silanization can't increase the shear strength.
