The V-Primer material was effective for bonding between Ag–Pd–Cu–Au alloy and Dentacolor [7], Visio-Gem [8], and Axis [9] composites. An evaluation study comparing the effect of priming agent demonstrated that adhesive performance of the Alloy Primer and Metaltite agents was better than that of the V-Primer material, when the Axis composite was bonded to an Ag–Pd–Cu–Au alloy Selleck ATM/ATR inhibitor [9]. Single liquid primers were used in combination with resin-based luting agents. An initial evaluation exhibited that durability of bond the Super-Bond C&B resin joined to Co–Cr and Ag–Pd–Au–Cu alloys was comparable [10]. The Super-Bond

C&B resin consists of the TBB initiator, methyl methacrylate (MMA) monomer liquid with 5% 4-methacryloyloxyethyl Dolutegravir cost trimellitate anhydride (4-META), and finely pulverized poly(methyl methacrylate) (PMMA) powder (4-META/MMA-TBB resin). According to a 100,000-thermocycling evaluation, bond strength to Ag–Pd–Cu–Au alloy of the Super-Bond resin was 23.0 MPa without application of primer, whereas 38.1 MPa with application of the V-Primer material [11]. Another 100,000-thermocycling evaluation showed that durability of bond to gold and Ag–Pd–Cu–Au alloys using the V-Primer and Super-Bond materials was comparable [12]. Adhesive performance of the Metaltite material (MTU-6) was somewhat different form that of the V-Primer. The Metaltile material combined with the Super-Bond resin exhibited greater

bond strength to Ag–Pd–Cu–Au alloy than the two alloys for metal-ceramic restorations [13]. Bonding performance Cyclin-dependent kinase 3 of thione primers combined with composite luting agents was also evaluated. The results showed that significant difference in bond strength to Ag–Pd–Cu–Au alloy was not observed between the Alloy Primer-Panavia F system and

the Metaltite-Bistite II system [14]. Kajihara et al. [15] examined influence of citric acid-ferric chloride aqueous solution on bonding to dentin or Ag–Pd–Cu–Au alloy. The results showed that bond strength to dentin of the Super-Bond C&B resin was not negatively affected by combined application of thione primers and citric acid-ferric chloride solution. However, application to Ag–Pd–Cu–Au alloy of citric acid-ferric chloride solution negatively affected the usefulness of two thione primers. Koishi et al. [16] compared bond strength of two acrylic resin materials to Ag–Pd–Cu–Au alloy. The results showed that TBB-initiated acrylic resin (Super-Bond) combined with one of the two thione primers showed greater post-thermocycling bond strength than benzoyl peroxide-amine initiated resin (Multi-Bond). The influence of alumina air-abrasion on bonding to Ag–Pd–Cu–Au alloy was evaluated apart from the effect of thione primer. Ishii et al. [17] reported that post-thermocycling bond strengths to Ag–Pd–Cu–Au alloy of the Super-Bond resin were improved by application of high-pressure air-abrasion.
