Adhesive Primers for Bonding Cobalt–chromium Alloy to Resin by K. Yoshida; K. Kamada; M. Atsuta is a Dentistry article available to read on EtoBox.

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 an
