“…22 Also in other studies a stable bond strength between Superbond C & B and alloys was not achieved. 21,23 The bond strength of the MDP-containing composite resin Panavia 21 (group S-P) showed the highest bond strength. Although a slight decrease in bond strength over 150 days storage time was observed, it was not statistically significant.…”

“…Traditionally, nickel-chromium [11][12][13] and cobalt-chromium 12,14) alloys are used for the retainers. This is largely because of well-established, durable bonding of adhesive resin cements to nickel-chromium 15,16) and cobalt-chromium 17,18) alloys. However, noble metal ceramic alloys are preferable and superior in terms of castability, workability, corrosion resistance, and biocompatibility 19,20) .…”

INTRODUCTIONResin-bonded fixed partial dentures with cast metal frameworks have emerged as a minimally invasive, aesthetically pleasing, and predictable treatment option for abutment teeth [1][2][3] . Two key factors contribute to this emerging trend: improvement in retainer design [4][5][6] and availability of metal primers which react directly and chemically with the bonding surfaces of noble metal alloys, such as silver-containing gold-palladium alloys 7,8) and type IV gold alloy [8][9][10] . Noble metal alloys are not suitable for cases that require high-quality aesthetic appearance. To satisfy both aesthetic and functional demands, the optimal alternative is resin-bonded fixed partial dentures fabricated with metal alloy frameworks and porcelainfaced pontics. Traditionally, nickel-chromium [11][12][13] and cobalt-chromium 12,14) alloys are used for the retainers. This is largely because of well-established, durable bonding of adhesive resin cements to nickel-chromium 15,16) and cobalt-chromium 17,18) alloys. However, noble metal ceramic alloys are preferable and superior in terms of castability, workability, corrosion resistance, and biocompatibility 19,20) . Macro-mechanical retention and micro-mechanical retention are two critical factors that influence the clinical success and longevity of fixed partial dentures. Macro-mechanical retention depends on abutment preparation and precision of fit of retainers. Micromechanical retention is achieved by chemical bonding, which in turn can be achieved with surface modification of metal substrates or application of metal primers [7][8][9][10] .On the former, currently available surface treatment methods range from tin (Sn) plating 13,21,22) to thermal silica coating (Silicoater MD) 22) and tribochemical silica coating (Rocatec) 23) . On the latter, adhesion promoting monomers play an important role in improving bonding, which is especially vital for restorations with compromised retention form.For base metals, it was shown that the presence of both TBBO initiator and 4-META functional monomer at the resin-metal interface during the setting reaction improved the bonding to cobalt-chromium alloy 18) . For noble metals, inclusion of thiirane monomers as an adhesive monomer component of MMA-TBBO resin improved the bonding to dental precious metal alloys 24) . Studies 25,26) have also shown the positive effect of metal primers on the bonding of 4-META/MMA-TBBO resin to high-gold-content metal ceramic alloys. At the same time, these studies 25,26) revealed the inadequacy of these primers on bonding to pure palladium (Pd) and highpalladium-content metal ceramic alloys. Although some studies 7-9) have reported on the efficacy of metal primers in improving the bond strength to Pd-containing alloys, it must be highlighted that these alloys contained other metals such as Ag and Cu, which are compatible with numerous primers 25) . The purpose of this study was to evaluate the effect of adhesion promoting monomers on bonding of MMA-TBBO resin to Pd. Although pure Pd is not use...

Objective To compare the bond strength of two dual-cure resin cements to Ni-Cr alloy test specimens (TS), with and without surface treatment. Methods RelyX ARC and Panavia Fluoro RESUMO ObjetivoComparar a força de adesão de dois cimentos resinosos duais em liga de Ni-Cr, em corpos de prova (CP) com e sem tratamento de superfície. MétodosOs cimentos Rely-X ARC e Panavia Fluoro Cement foram testados. Oitenta CP foram fundidos em liga de níquel, nas dimensões 10mm x 7mm x 2,5mm em um total de 40 pares. Quatro grupos de CP foram obtidos. Vinte pares foram tratados com jato de alumínio de 50µm e 20 sem tratamento. Os CP foram limpos em ultrassom. As peças foram cimentadas conforme instruções dos fabricantes. O ensaio de cisalhamento foi conduzido até o momento da falha adesiva. ResultadosA análise da variância (ANOVA) mostrou que houve diferença estatística (p>0,05) entre os grupos. A análise visual das imagens de microscopia óptica mostrou um padrão de fratura mista com predomínio adesiva para o Rely-X ARC e mista com predomínio coesiva para o Panavia F. Os grupos jateados obtiveram melhor adesividade, onde o Panavia F alcançou valores maiores que o Rely-X ARC.Conclusão O grupo liga de Ni-Cr/Panavia F em superfície tratada se comportou melhor em termos de adesividade.Termos de indexação: Resinas compostas. Cimentos dentários. Resistência ao cisalhamento.
