“…In the previous studies reporting the comparative results for the bond strength between porcelain and indirect composite resin, Ciftci et al 27 and Almilhatti et al 28 reported that in the experiment to measure the bond strength for Ni-Cr alloy, the bond strength would not be equal to that of porcelain. However, Petridis et al 29 measured the bond strength for the group bonding gold alloy for porcelain, feldspatic porcelain and the counterpart for three kinds of indirect composite resins before and after thermocycling.…”

“…Metal-ceramic adhesion could be tested with various methods such as shear strength test, three-or four-point bending and biaxial flexural test 4,6,12,17,18) . Although ceramic is resistant to compressive and tensile forces, it shows less resistance to shear and oblique forces where the latter represents the worse-case situation 9,11) .…”

It is often difficult to predict the metal types but clinical findings indicated that CFM FPD failures are frequently experienced in the form of ceramic fractures with metal exposures 3,4) .

“…Despite the development and growing use of all ceramic systems 1,2) , ceramic-fused-to-metal (CFM) fixed dental prostheses (FDP) are still considered a good option for oral rehabilitation due to their mechanical strength [3][4][5][6] , presenting also significantly less clinical failures as opposed to all-ceramic ones 7) . However, the high cost of gold and gold alloys caused an increased trend towards the use of non-precious metal alloys for CFM FDPs.…”

This study compared the bond strength between metal alloys and 5 ceramic systems. Ceramic systems (Vita VMK68, Ivoclar IPSd. SIGN, Ceramco II, Matchmaker and Finesse) were fired onto either Ni-Cr or Co-Cr base metal alloy. Metal-ceramic interfaces were subjected to shear loading until failure. The ceramic type significantly affected the bond strength results (p<0.05). For Ni-Cr alloy, the results ranged between 15.4-25.3 MPa and for Co-Cr alloy between 13.3-19.0 MPa. The highest mean bond strength value was obtained with the combination of Ni-Cr alloy-Ceramco II (25.3 MPa), the lowest bond strength was received from the combination of Co-Cr alloy-Ivoclar IPS d.SIGN ceramic (13.3 MPa). Adhesive failures between metal and ceramic were significantly more frequent with Ni-Cr alloy (31 out of 50) than with Co-Cr (20 out of 50) (p<0.05). Ceramco II presented the highest bond strength with both Ni-Cr and Co-Cr being significantly different from one another.

(1) VOJNOMEDICINSKA AKADEMIJA, KLINIKA ZA STOMATOLOGIJU, BEOGRAD, (2) CENTAR VOJNOMEDICINSKIH USTANOVA 11000 BEOGRAD Sažetak:Uvod/cilj. Istraživanje je sprovedeno sa ciljem da se utvrde i kvantifikuju promene sastava metal-keramičkog međuspoja bazičnih dentalnih legura koje su podvrgute postupku višestrukog livenja. Ponovna upotreba dentalnih legura (recikliranje) je dosta česta pojava prilikom izrade fiksnih zubnih nadoknada, a bez obraćanja pažnje na funkcionalnu trajnost gotove krune ili mosta. Kvantitativnom i kvalitativnom analizom metal-keramičkih međuspojeva treba pokazati da li se može opravdati postupak recikliranja legura, odnosno ispitati uticaj ponovljenog livenja legure na hemijski sastav njenog spoja sa keramikom. Metode. Eksperimentalna studija je izvedena na leguri Wirobond-C koja višestruko livena kroz 12 generacija recikliranja. Analizirano je ukupno 24 uzorka -po 6 uzoraka u svakoj grupi (grupa A -prvo livenje, grupa B -treće recikliranje, grupa C -šesto recikliranje i grupa Ddvanaesto recikliranje). EDX analiza je sprovedena u aparatu "Inca X-Sight" (Oxford Instrumensts) uz upotrebu SEM mikroskopa "JEOL" tip "JSM 6460 LV" (Tokio, Japan). EDX analiza pripremljenih uzoraka obavljena je pod sledećim uslovima: frekvencija elektronskog snopa 20.000 impulsa u sekundi, napon snopa 10 KV, vreme akvizicije 250 sekundi, analizirani opseg energije X-zraka 0 do 10 KeV. Kvantitativna EDX analiza metal-keramičkog međuspoja vršena je primenom računarskog programa "INCA" (Oxford Instruments), u odnosu na odgovarajuće metalne i nemetalne standarde. Rezultati. Sve metalne komponente iz legure kako je povećavan broj livenja permanentno su opadale u sastavu metalkeramičkog međuspoja, dok su elementi koji su poreklom iz keramike povećavali svoju zastupljenost. Pojedinačna analiza pokazuje da višestruko livenje legure Wirobond-C u najvećoj meri čini da se smanjuje udeo cerijuma u metal-keramičkom međuspoju. Međugrupna razlika sastava metal-keramičkog međuspoja je značajna posle prvog livenja i šestog recikliranja legure (p<0.001; p<0.002; t-test nezavisni uzorak). Zaključak. Ponovno livenje bazičnih legura kobalt-hrom ne može se preporučiti zbog promene sastava metal-keramičkog međuspoja. Recikliranje ovih legura izaziva značajne promene u metalkeramičkom međuspoju , sa mogućim posledicama u vidu slabljenja međuspoja i oštećenja keramike u toku mastikacije. Ključne reči: Energijska disperziona spektrometrijska(EDX) analiza, Fiksne zubne nadoknade, recikliranje dentalnih legura Summary:Background/Aim. The aim of this research was to determine and quantify changes in the composition of metal-ceramic bond in the base dental alloys submitted to the procedure of multiple casting. Recusing (recycling) of dental alloys is performed very often in the fabrication of fix dental restorations, however, paying no attention to functional durability of the made crown or bridge. Quantitative and qualitative analyses of metal-ceramic bonds should show if recycling of alloys could be justified, that is to estimate the influence of ...
