| 520 | _aThe purpose of this study was to investigate the effect of different surface treatment (sandblasting, gold coating and acid etching) on the fracture resistance of milled titanium veneered crowns. Twentyone titanium based crown samples were fabricated and randomly assigned into three groups each of seven samples according the titanium surface treatments; Group I: Titanium crowns subjected to sandblasting, Group II: Titanium crowns subjected to gold coating, Group III: Titanium crowns subjected to acid etching. The samples after surface treatment were examined with SEM microscope. Then veneering with low fusing porcelain. Fracture resistance bond strength was tested. Debonded samples were examined with SEM microscope. Data were collected, tabulated and statistically analyzed (p{u2264}0.05). Regarding the effect of surface treatment (sandblasting, acid etching and gold coating) on surface roughness, it was found that; no statistically significant difference between mean Ra values of sandblasting group (1.32 ± 0.20 æm) and acid etching group (1.42 ± 0.30 æm); both recorded the highest mean values. Gold coating (0.17 ± 0.06 æm) recorded statistically significantly lower mean Ra value | ||
