Bond strength of bimaterial acrylic resin combinations.
While further research is necessary on the subject of the strength and nature of the bond between different types of acrylic resins, our study shows that specimens fabricated from heat-accelerated BPM showed considerably higher transverse strength values when compared with the various bimaterial combinations. From this, and from the fact that all bimaterial combinations broke at the joining interface, it can be inferred that none of the acrylic resin bimaterial combinations developed a true "chemical bond."
