ABSTRACT

The aim of this study was to evaluate the compomer cement and resin cement as an orthodontic band cement on zirconia crown. A total of 30 specimens were prepared. Preformed stainless steel crowns and zirconia crowns of upper right second primary molar were used. Orthodontic bands were cemented on stainless steel crowns (Group Ⅰ, n = 10) and zirconia crowns (Group Ⅱ, n = 10) with compomer cement. The other bands were cemented on zirconia crowns with resin cement (Group Ⅲ, n = 10). The tensile loads were applied to band to measure the bond strength. The mean of bond strengths of group Ⅰ, Ⅱ and Ⅲ were 0.79 MPa, 1.09 MPa and 1.56 MPa respectively. Bond strength of group Ⅱ is significantly higher than group Ⅰ. There was no significant difference between group Ⅱ and Ⅲ. Compomer cement and resin cement containing functional monomers showed favorable bond strength of orthodontic bands.
