Bread & Butter with Tetric CAD HT

I received a sample of Ivoclar Vivadent's Tetric CAD. This was a case that I thought would be more of an onlay and my mind was dead set on using the block.  In my humble opinion this block is perfect for inlays and onlays.  The tooth's condition dedicated my prep and with the presence of distal decay that wasn't apparent on the radiograph and with the small buccal breakdown, I changed gears and went with a crownlay prep.  In the past, I would typically use IPS e.max HT or MT for these crownlay indications.  

Tetric CAD is in the category of hybrid ceramics.  It has great edge stability during milling, polishes easily and doesn't have to be fired.  With a flexural strength of 272 MPa, it is higher than the other hybrids.  I bonded this restoration with Ivoclar Vivadent's Variolink Esthetic DC Warm cement under rubber dam isolation. I have attached a CEREC Materials spreadsheet that I posted earlier this month for those that would like to see the different materials and their properties and indications.  

This appointment was less than an hour from start to finish.  Polished only.  Despite the fact that the value is a bit high occlusally, it still blends beautifully around the margins.
