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.
