PERO, Ana C. et al. Shear bond strength between artificial acrylic resin teeth and denture base resins. Polímeros [online]. 2007, vol.17, n.3, pp.194-200. ISSN 1678-5169. http://dx.doi.org/10.1590/S0104-14282007000300007.
Shear bond strength between artificial acrylic resin teeth and denture base resin was evaluated under the influence of two brands of artificial teeth (Biotone and Trilux) and three denture base resins. Two of these resins were conventionally polymerized in water bath (QC-20 and Lucitone 550), while the other was a microwave-polymerized resin (Acron-MC). The evaluations were done by means of a shear bond strength test with application of a perpendicular load to the interface tooth-resin. The results showed that, for the same denture resin, the strength was similar regardless of the tooth brand. Also, for the two evaluated brands of tooth, the resins Acron MC and Lucitone 550 presented similar shear bond strengths, which were statistically higher than for resin QC-20.
