My number one factor in avoiding post-treatment sensitivity following the delivery of indirect restorations is the management of force dynamics in the occlusal morphological design.  This is one reason I like the virtual digital design to control occlusal contact placement.  This video's occlusal design concept uses Primescan and the latest CEREC software.  These principles apply to Exocad and 3 Shape software, and I am also branching into these virtual design softwares.
