Notes:
This study evaluated the effect of five adhesive primers on the shear bond strength of a self-curing resin to cobalt–chromium (Co-Cr) alloy. The adhesive primers Acryl Bond® (AB, Shofu), Cesead Opaque Primer® (COP, Kuraray), Metacolor Opaque Bonding Liner® (MOBL, Sun-Medical), Metal PrimerII® (MPII, GC) and MR. Bond® (MRB, Tokuyama) were used. A brass ring which was placed over the casting alloy disk surface non-primed or primed with each primer was filled with the self-curing MMA-PMMA resin. The specimens were stored in water at 37 °C for 24 h and then immersed alternately in water baths at 4 °C and 60 °C for 1 min each for up to 50 000 thermal cycles before shear mode testing at a crosshead speed of 0·5 mm/min. All of the primers examined, except MOBL, improved the shear bond strength between the resin and Co-Cr alloy compared with non-primed specimens prior to thermal cycling. Regardless of which primer was used, the shear bond strength significantly differed between thermal cycles 0 and 50 000. However, after 50 000 thermal cycles, the bond strengths of resin to Co-Cr alloy primed with COP or MPII were significantly greater than those of specimens primed with AB, MOBL or MRB and non-primed controls. This study indicated that COP and MPII are effective primers to obtain higher bond strength between resin and Co-Cr alloy.
