For 3.85 version and prior, I still prefer the Correlation Jig when taking a veneer optical capture for multiple maxillary incisor veneers. The new posted video in chapter 9 will review the capture "Correlation Jig" technique used in the Klim office. Benefits of Correlation Jig 1. Fewer optical captures required. 2. Ideal 60 degree capture of veneer preparation(s). 3. Very efficient. 4. Less likely to see the 3.83 Triangulation window error during the design phase.
