  • Title: [Tensile tests of variably conditioned metal specimen glued with hybrid composite].
    Author: Marinello CP, Luthy H, Krüger K.
    Journal: Dtsch Zahnarztl Z; 1989 Oct; 44(10):748-50. PubMed ID: 2700326.
    Abstract:
    The purpose of this research was to analyze simultaneously the effect of 4 factors (metal conditioning, bonding agent, metal silicoating and water storage) on the tensile behavior of a Bis-GMA-resin (hybridfilled) bonded Ni-Cr-Be alloy by analysis of variance with a multifactorial design. The results showed that water storage of 33 days and the presence of bonding agent had no effect. In contrary, electrolytical etching or silicoating influenced significantly and positively the tensile bond strength. In addition a significant factors interaction between metal surface conditioning (sandblasting vs. etching) and silicoating was detected. Metal sandblasting followed by silicoating reacted more favorably than the combination etching/silicoating. In all cases the mechano-chemical adhesion (silicoating technique) resulted in a composite bond strength that was far superior to that of conventional pure mechanical bonding.
