Michael Snider I've had the opportunity to use the new Tetric Cad material from Ivoclar for a few weeks now. This material is a great addition to the current available resilient/hybrid materials that we already have.
I really despise doing quadrants of composites. There's nothing I dislike more than trying to get good contours, interproximal embrasures and contacts with sectional matrices, rings, and wedges.
I would rather let the CEREC do the work for me.
This case walked in a few days ago.
Pt needed partial coverage restoration on #14 and also a restoration on #13.
Sure, I could have prepped a crown on #14. But I prefer to save tooth structure and not do full coverage unless absolutely necessary. Rather than filling #13 directly, with the CEREC Im able to create better emergences, and more predictable contacts.
The Tetric CAD material mills very quick and clean due to the resin component of the block. Using two Milling Units, both restorations were done in under 8 min.
After milling, my assistant removes the sprues, defines the anatomy and polishes the restorations with the Lava Ultimate Polishing kit from Diashine.
Per the IFUs, the intaglio of the restorations were sandblasted and then Adhese Universal was applied, air thinned and not cured.
Enamel was selectively etched with phosphoric acid, Adhese universal applied, air thinned and cured. Variolink Esthetic DC was placed into both preps, and the restorations were seated. This cement is great with a long tack cure making multiple units easy to clean up.
We selected Variolink Esthetic DC Warm with the MT A3 Tetric CAD and ended up with a nice final shade. The warm cement along with the MT block also helps to block out some of the underlying discolored tooth structure.
Forgive the immediate post op pic.
Entire appointment from anesthesia to post op BW was under one hour.
Pt was thrilled
