Abstract:
Objective:To compare the shear bonding strength between two kinds of veneering ceramics respectively bonded to Vita Mark II.Methods:Vita Mark II samples were prepaired in the size of 8 mm ×6 mm ×2 mm.Veneering ceramic VM9 and Titankeram-ik were sintered on the Vita Mark II blocks respectively(n =1 0).The shear bond strength of each specimen was measured,the failure mode of the fracture surface was observed by SEM.The element in the bonding interface was analysed by field emission scanning elec-tron microscope(FE-SEM).Results:The values of shear bond strength (MPa)of VM9 and Titankeramik groups were 36.1 7 ±8.91 and 42.07 ±8.31 respectively(P >0.05).SEM observation showed tight bond between the two materials,FE-SEM results showed penetration of Al element from MarkⅡblock into veneering porcelain VM9 or Titankeramik.Conclusion:Veneered porcelain of VM9 and Titankeramik can be used as the individual veneering ceramics for Vita Mark II blocs.
