This video tutorial will review my two Omnicam impression techniques.  Having been a beta tester for the Omnicam, this camera is opically error proof.  As long as the data is complete over the preparation and adjacent contact zones, it will fit!  One important point, the Bluecam AC will provide equally as good virtual information and milled restorations as the Omnicam.  I am still using both systems.  Don't be discouraged or upset if you use the Bluecam, you are able to produce the same quality of restorations.
