the volumetric shrinkage was measured
following iSO Draft Date: 2007-07-10
(Dentistry - Polymerization shrinkage of
filling materials) specifications.
this study demonstrated that
the shrinkage stress generated
by G-ænial is amongst the
lowest of the tested
composites.
6.3 three – body wear resistance
Wear is the loss of material resulting from removal of the material through the contact of two or
more materials. the three-body wear test simulates wear in the oral cavity using a slurry of Pmma
and glycerol as the intermediate abrasive agent and an acrylic plate as the opposing material.
