Adult orthodontics is a currently emerging trend among publics. Since prosthetic restorations with zirconia crowns are also more frequently seen,so the need to bond orthodontic brackets onto zirconia crowns have become a essential. It is necessary to have a sufficient bond strength for efficient treatment outcome. As studies reporting about bond strengths silane ,when used for bonding orthodontic brackets onto the zirconia surfaces were barely seen, this in vitro study was conducted to evaluate the bond strength of the two different adhesion promotors, namely monobond and 3M ceramic primer used for bonding metal and ceramic brackets to zirconia surfaces. Zirconia blocks were embedded onto acrylic blocks and orthodontic brackets(metal and ceramic) were bonded on them using two adhesion promoters namely monobond and 3M primer. The bond strengths of the four groups were tested. In addition, the adhesive remnants on the zirconia surfaces upon debonding were also evaluated, using light microscope. In this study, the results concluded that the mean shear bond strength of monobond showed higher bond strength than 3M primer. The ARI revealed 3M ceramic primer were performed better.
