26)μm vs (76.25±8.37)μm, P less then 0.05]. The intensity was significantly higher than that of group B [（11.35±3.29）N vs （7.24±2.07）N, P less then 0.05]. Under electron microscope, the metal layer of group A was more closely combined with the porcelain layer. CONCLUSIONS The marginal fitness and bonding strength of metal base crowns made by laser printing and traditional casting methods are acceptable. Laser printing metal base crowns have better marginal fitness and stronger bonding strength between metal and porcelain,
