Correlation of Ultrastructure with Mechanical Properties of Nano‐Hybrid Dental Composites

Abstract

Determination of mechanical properties of nano‐hybrid dental composites leads to strong correlation to material's ultrastructure. Not only does total filler content in percentage of weight affect the mechanical properties, but the combination of optimal filler size and shape with homogeneous distribution of filler particles and an optimal amount of different sized fillers in finally cured dental composites lead to desired mechanical and thermo‐mechanical properties.

Polymer-Nanoparticle Composites: From Synthesis to Modern Applications

“…A comprehensive overview was published by Ramakrishna and coauthors in 2001 [ 248 ]. In a recent publication the impact of the particle size, distribution, and geometrical shape on the resulting mechanical properties of different composites suitable as dental filling materials for substituting amalgams was summarized [ 249 ]. The authors found, that especially the homogenous nanoparticle distribution in the matrix ensured a long dental filler lifetime.…”
