The aim of this work was analyze the effect of the soldering comparatively in the fit of the interface abutment/implant of fixed prostheses of three elements, starting from two masters models in aluminum, configured in arch and straight line. The results of two different soldering processes were compared it welds to * laser and brazing applied in the union of the castable UCLA abutment of 12 models of work of three elements, melted in league of NiCr. The same ones were divided in four groups: Group A, welds laser/arch; Group B, brazing/arch; Group C, welds laser/straight line and Group D, brazing/straight line. After the casting stages and it welds respectively, the prostheses carne back to the master model for evaluation of the abutment/implant interface; it was used for the analysis, an scanning electron microscope (LEO-435 VP-Germany), in the increase of 500x. The results were submitted to statistical treatment (p>0,05). Significant statistical vertical adjustment differences were not observed among the different soldering processes and eithex with relationship to the different configurations when compared. Although was verified in the models worse values of the vertical and horizontal adjustment after the soldering processes.
