I have recently started looking at Vita Suprinity, a new zirconia reinforced Lithium Silicate material (release late summer 2014). I have not had a lot of time to fully make an evaluation, but I wanted to post some initial impressions concerning the milling of the material.

This case was a replacement of a failed ceramic crown on tooth #30. Because of the desire to leave the buccal margin in enamel and due to the confines of the previous prep, I decided to prepare the buccal margin very thin.

Normally this can be accommodated by many different ceramics with experience, but I wanted to take Suprinity one step further and simply fast mill the material with a margin thickness parameter of only 50 microns. Not only did the crown mill extremely quickly (6:47), but it also milled a perfect margin on that very thin area. It was quite impressive.

One of the other neat advantages of this material in its immediate milled state is that you can literally see the prep and margin right through it. It was quite odd I must say, but helpful in evaluating the clinical fit.

Suprinity is a unique material that seems to have some promise. Specifically milling to very thin margins. I look forward to trying it out some more.

To all out there:
I am in the process of looking at CBCT machines. I have been a cerec user for two years now and have been enjoying the experience. I have spent the last year training to place my own implants. I have looked at all the major manufactures and have gotten a few very cost effective offers to buy a CBCT that is not made by Sirona. The one company that has made the most attractive offer is Vatech. They are offering me there midsize unit that has an 8x8 field of view for $73,000.00 shipped and installed. This includes a 7 year parts and labor guarantee. They claim to have the best image quality on the market. My question to all is what am I giving up by not having cone beam and cerec truly integrated . I have heard that Sirona's censor technology is old and there image quality not as good as the competition. I have also heard that other CBCT machines will work with Cerec and I would not be sacrificing much at all in the way of integration. Is it worth the additional expense to purchase CBCT from Sirona. You honest and unbiased opinions would be greatly appreciated.
Thanks,

Nice. I'm curious to see the final photo.
