5a. Grandio† x5000 after 100,000 cycles.
Note the gaps at the interface of the glass fillers and the resin matrix.
additionally, voids can be observed where fillers were lost.
5b. Clearfil Majesty Esthetic† x1000 after 100,000 cycles. Note the loss of
pre-polymerized fillers and gaps at the interface of the particles and the
resin matrix.
5c. Estelite Quick† x1000 after 100,000 cycles.
note that the interface between the pre-polymerized fillers and the resin
matrix is no longer continuous and that the fillers are no longer an intrinsic
part of the matrix.
in another test, the wear resistance of KalORe was compared to a number of other composite
materials. Both the wear resistance data and SEM images confirmed that materials with a higher
shrinkage stress demonstrate greater particle loss from the matrix, resulting in more wear.
