ABSTRACT:
The present invention provides novel dental impression materials, the cure of which can be monitored visually, comprising: (1) a curable silicone polymer; (2) a crosslinker compound containing silicon-bonded-hydrogen groups; (3) a hydrosilation catalyst; and (4) one or more cure-indicating dyes that exhibit a color change in the presence of a silicon-bonded-hydrogen compound and a hydrosilation catalyst. The cure-indicating dye provides the composition with an initial pre-cure color and a different post-cure color. As a result of this change in color, the state of cure of the impression material can be visually monitored.
