Resumo
This study aimed to develop experimental dental
restorative composites by the addition of montmorillonite
(MMT) nanoparticles in a polymeric matrix-based
BisGMA/TEGDMA, to assess the possibility of a different
dimensional behavior during the photo-polymerization.
The characterization of experimental composites was
established with the following analyses: thermal–mechanical
analysis (TMA), X-ray diffraction (XRD) and transmission
electron microscopy. Data for TMA were analyzed
using one-way ANOVA and Tukey test (p\0.05). It was
observed that the experimental composites filled with
MMT nanoparticle showed statistically similar polymerization
shrinkage values (by TMA analysis) in the concentration
of 30% and statistically lower polymerization
shrinkage values in the concentration of 50%, compared to
composites filled with barium glass (BG—control groups).
These results may be related to the interaction polymeric
matrix/MMT nanoparticles and the formation of
nanocomposites, observed by XRD and TEM analyses.
