Abstract

© 2022, The Author(s) under exclusive licence to Australian Ceramic Society.The aim of this in-vitro study is to compare the shear bond strengths of ceramic brackets bonded to zirconia surfaces by using different primers. Forty rectangular-shaped zirconia blocks were manufactured at 10 × 5 × 2.5 mm. Zirconia surfaces were sandblasted with 30-μm aluminum-oxide particles. Afterward, thermocycling for 2000 cycles and a shear bond strength test was applied. Universal primer (Monobond-Plus, Z Prime Plus, Clearfil) was applied to all specimen surfaces. The upper central ceramic brackets were bonded with light cure adhesive paste (3 M Transbond XT) to zirconia surfaces. The samples were equally divided into four groups according to the primer used in the bonding procedure: group I (control group), group II (Clearfil group), group III (Monobond-Plus group), group IV (Z Prime Plus group). The Z Prime Plus adhesive primer showed statistically higher shear bond strength values than that in the Monobond-Plus and control group. The results in the control group were statistically significantly different from the values obtained in all other groups. Monobond Plus, Z-Prime Plus, and Clearfil ceramic primer agents can be effective methods for bonding zirconia restorations with ceramic orthodontic brackets.
