Qualitative Assessment of the Defects in Metal Casting Prosthetic Restorations

Due to the frequent occurrence of casting defects in the casting process of metal prosthetic elements, studies aiming at identifying the defects and determining their probable causes were performed. The work presents the results of the examinations of the Co-Cr-Mo alloy, brand name Argeloy N.P. Special, used for prosthetic restorations. Macroscopic and microscopic observations were conducted with the use of light and scanning microscopy (SEM). Also, the results of the observations by means of a 3D scanner by GOM ATOS 3 were presented. The performed research made it possible to determine and classify casting defects such as blisters, misruns and interscrystalline cracks. It was stated that a stabilized technological process affects the elimination of the casting defect formation.
