The CEREC Chairside Software 4.3 makes a few changes to our existing set of tools. Incisal Variation is one of those tools. Previously we had one type of morphology to use and could then vary the strength of that morphology. Now we can select up to 6 different morphologies. 

The variation is chosen with a slider located in the tool drop down menu. The variation can be increased in strength the same as it was in the previous software with a slider located just above the variation slider. The variation can also be positioned by highlighting the tooth and then moving the variation around to the position you want it to be in.  Now there are more options of us to customize our anterior restoration that will reduce the post milling refinements.
