Purpose: The aim of the present study was to evaluate and compare the shear bond strength of feldspathic ceramic (VITA VM 9), and IPS e.max Ceram veneered on zirconia cores.
Materials and methods: A total of 50 zirconia cylindrical discs measuring 10 mm in diameter and 3 mm in thickness were milled. 3M zirconia blanks were used to fabricate the zirconia cores. Half of the samples (n = 25) were layered with VITA VM 9 (group I), and the remaining samples were layered with IPS e.max Ceram (group II). The layered specimens were compressively loaded under a universal testing machine till fracture occurred. An independent samples t-test was done to compare the mean shear bond strength of two independent groups.
Results: Specimens in group II, layered with IPS e.max Ceram, showed higher bond strength (1466.76 N) compared to group I, layered with VITA VM 9 (1274.12 N). The difference was significant (p = 0.047).
Conclusion: Specimens layered with IPS e.max Ceram showed better bond strength than specimens layered with VITA VM 9. Hence, in patients with heavy occlusal loads, parafunction habits, multiunit restorations, or in cases of posterior rehabilitation, layering with IPS e.max Ceram can be considered.
