Some of you are starting to receive the 4.50 software update.  Make sure to update to the latest patch 4.51.  If you have one of the latest towers, your system should perform well with this CEREC software update.  If not, the system may need a few hardware tweaks until it is operating well with this version of the software.  One of my most appreciated assets in the 4.5+ software is margin clarity.  Has been significantly improved and easier to identify the margins.  The linked video will demonstrate the latest in finding and drawing margins.  I call it the emotional restorative peace factor.  Margins are one of my things that make my day go well when they are on.  Must have it.  Well, this software update is a home run in the margin ares.  View Video.
