Effect of metal type and surface treatment on shear bond strength of resin cement (in vitro study)

Background Resin bonded fixed partial dentures appeared to prevent the excessive preparation of dental tissue Investigation of surface treatments to improve the bond of resin cements to metals may contribute to the longevity of these restorations. Due to the potential lack of ideal preparation form the type of alloy and its surface pretreatment may have clinically relevant correlations with the retentive strength of castings to minimally retentive preparations Aim The aim of this search is to study the bonding resin cement strength to different types of the metal alloy due to the surface treatment Purpose Evaluate the effects of two different surface treatments on shear bond strength SBS between a palladium silver alloy Pb Ag and commercially pure titanium CP Ti cast alloy with resin luting cements
