“…Thus, the silver palladium alloy can be remelted several times. Liu et al 15 indicated no significant differences in metal-ceramic bonding for the Au-Pd alloy W-5 and the Pd-Ag alloy IPS d.SIGN 53 when they were cast up to 3 times.…”

“…14 However, the loss of trace base metal such as Zn, In, Sn, and Fe during the recasting of noble alloys for porcelain can be detrimental to their castability and cause the formation of an oxide layer during initial oxidation; this could adversely affect porcelain bonding. 15 Metal ceramic prostheses possess clinical longevity because of the strength of the bond between the metal framework and the porcelain. Therefore, this study aimed to determine how recasting influences the bonding between metal and ceramic by using ANSI/ADA Specification No.…”

“…11 Papazoglou and Brantley 18 compared high Pd alloys after recasting three times by evaluating porcelain adherence and bond failure force and found no correlation between porcelain adherence and bond failure force. Liu et al 22 reported that after three castings all three noble alloys showed satisfactory bonding compatibility with porcelain. Kul et al 23 reported that noble alloys can be reused because there is no problem with porcelain.…”

Aim:The aim of this study was to evaluate the effect of recasting base metal alloy on the metal-ceramic bond strength. Materials and methods:A total of 60 test samples were prepared from new and recast nickel-chromium alloy and divided into six groups. In group A0, test samples were prepared from 100% new alloy. Groups A1, A2, A3, A4, and A5 were prepared from 50% new alloy and 50% casting remnants (sprue and buttons) of the previous group by weight. All these samples were coated with ceramic (IPS d.SIGN and Ivoclar-Vivadent), and samples were then subjected to three-point bending test to evaluate metal-ceramic bond strength. Results:The values were analyzed using one-way analysis of variance and Tukey's post hoc test. The mean bond strength of group A0 was higher than that of groups A1, A2, A3, A4, and A5. Conclusion:Metal-ceramic bond strength decreased significantly with multiple recastings.Clinical significance: Bond strength between metal and ceramic is a crucial factor for the clinical performance of metal-ceramic restorations. Recasting of alloys may affect the metal oxide layer composition and thickness of metal-ceramic interface, and thereby the metal-ceramic bond.

“…Svaki put kad se legura pretopi izgubi se deo ovih lako-oksidujućih elemenata, što može uticati na vezu legure i keramike [24]. Sve navedeno može rezultirati slabljenjem metal-keramičkog međuspoja i sledstvenim lomljenjem, ili odlubljivanjem keramike od legure [25,26].…”

Eksperimentalna studija je sprovedena sa ciljem da se kvantifikuju promene metalkeramičkog međuspoja dentalnih nikl-hrom legura koje su podvrgnute ponovnom livenjurecikliranju. 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 metalkeramičkom međuspoju.
