UltraShield showed no staining after washing as opposed to the conventional composite.
UltraShield: At 20N no obvious marks appear
● Using a 1 mm needle to mark the composite
Conventional Composite: At 8N marks appear
● Testing done under 8N-20N of pressure
● Testing Standard used: FLTM BO 162-01
After 1000 turns 23mg of material was worn off of UltraShield
After 1000 turns 81mg of material was worn off of the Conventional Composite
Tested in a QUV chamber for 3000 hours.
Experts say no visible color can be observed at a Delta E < 5.0.
● Observations and recordings were taken every 500 hours
Pictures below show UltraShield after a 90 hour boiling test.
The results show no separation between the cap layer and the core, no damage, and no cracking
