Composite resin - Coggle Diagram
Composite resin
filler particles
quartz
silica
increase strength & reduce polymerization shrinkage
modern composite resin in use
2.4% ~ 2.8% shrinkage
at least 75% filler by weight
the smaller the average filler particle size, the better
resin with smaller particles are more polishable
improved wear resistance? p.470
It is difficult to maintain a high filler content
with very small filler particles
because small filler particles
possess a high ratio of surface area to weight
silane
allows for stronger bonding
improves wear resistance
permits the incorporation of
more iller into a given amount of resin matrix
