Abstract
Eksperimentalna studija je sprovedena sa ciljem da se kvantifikuju promene metal-keramičkog međuspoja dentalnih nikl-hrom legura koje su podvrgnute ponovnom livenju - recikliranju. EDS analizom metal-keramičkih međuspojeva potrebno je utvrditi da li recikliranje dentalnih legura ima negativan uticaj na sastav metal-keramičkih međuspojeva zubnih nadoknada. Ispitivanje je obavljeno na nikl-hrom leguri tipa "Wiron 99", proizvođača "BEGO" (Nemačka). Rezultati EDS analize su pokazali smanjenje zastupljenosti metalnih komponenti legure u metal-keramičkom međuspoju, koje je u direktnoj zavisnosti sa povećanjem broja livenja legure. Utvrđen je pad koncentracije nikla, hroma, cerijuma, niobijuma i molibdena u međuspoju nakon 12 livenja legure. Od svih elemenata legure najviše se smanjio udeo cerijumau međuspoju , sa 28 wt% na 16,26 wt%. Koncentracija nikla je pala sa 3,31 wt% na 1,82 wt%, hroma sa 2,95 wt% na 2,03 wt%, molibdena sa 8,71 wt% na 4,68 wt%, a niobijuma sa 9,82 wt% na 3,97 wt%. Ponovna upotreba bazičnih dentalnih legura se ne može preporučiti zbog smanjenja koncentracije elemenata legure u metal-keramičkom međuspoju.
