Abstract
The purpose of this study was: Structural characterization of two commercial nanocomposite materials (Premise /Kerr Corp and Tetric EvoCeram�/ Ivoclar-Vivadent); Evaluation of the marginal adaptation and adhesive interface achieved with two commercial adhesive systems (Optibond SoloPlus /Kerr Corp and G-Bond /GC). Investigation was done using electronic scanning microscopy (SEM).
Highlights
The purpose of this study was: Structural characterization of two commercial nanocomposite materials (Premise TM/Kerr Corp and Tetric EvoCeram®/ Ivoclar-Vivadent); Evaluation of the marginal adaptation and adhesive interface achieved with two commercial adhesive systems (Optibond SoloPlus TM/Kerr Corp and G-Bond TM/GC)
Air inclusions similar to those described in other nanocomposites could have been more rarely observed
The characteristics of the composition and size of the inorganic filler particles are essential: some materials - ex: Filtek SupremeTM/3M Espe - contain only isolated, or aggregated nanoparticles, while most nanocomposites have a hybrid composition - And Tetric EvoCeram - combining the mechanical advantages of barium borosilicate bottles, increasing the percentage of filler by means of prepolymerized and aesthetic particles, polish and handling of nanoparticles and nanomodifiers [5,15,17]
Summary
The purpose of this study was: Structural characterization of two commercial nanocomposite materials (Premise TM/Kerr Corp and Tetric EvoCeram®/ Ivoclar-Vivadent); Evaluation of the marginal adaptation and adhesive interface achieved with two commercial adhesive systems (Optibond SoloPlus TM/Kerr Corp and G-Bond TM/GC). After application of the adhesive systems, direct restorations were achieved by the layering and polymerization of each composite material.
