The author studied the stress distribution which occurs in casted metalic restoration a gold alloy type II and a copper-aluminum, with cavity preparation of both types: intracoronal or extracoronal cavity using the finite elements method in a first right inferior molar. The conclusion was that the mechanical performance of both are very similar. Stress occurred in a dental structure which alloy cast restoration are smaller than that occurred in a tooth without cavity preparation. The cavity preparation with intracoronal shows a better stress distribution in the dentine than that with extracoronal. In the region near the buccopulpal line angle occurs a stress concentration in despite of the type of the cavity metallic alloy used.
