eMax Has Been Prime Milled!

Lot’s of buzz about the CEREC PrimeMill!   It’s fast with zirconia, but what about eMax?    Well…..   this crown was milled in just over 5 minutes!    The newer generation of motors, tools, and tool paths allow for more efficient, and accurate, grinding!   

But, first a bit of history…    The first molar had recurrent caries in 2003 and we replaced the amalgam with a CEREC inlay.   We used Ivoclar Vivadent’s ProCad, which was the precursor to Empress CAD.   It was imaged and designed in the “red camera” software.  It’s been so long ago, that I can’t recall the software version number.  I would guess CEREC 2.2.  

 

Not too bad for a 17 year old inlay!    I’ve always been “aggressively conservative” with my preparations.   It was really the reason why I got into CEREC in the first place:  I wanted to make smaller restorations, but the TEMPORARIES were a nightmare.    I think there are MANY dentists that would love to do more inlays/onlays, but don’t have the confidence or education/experience to do them.  Just try it!    I do run a course just about partial coverage restorations.   Check out “Only Onlays” in the courses.   We also complete a couple of onlays in our CEREC Straight Forward class.  

In 2020, the technology has drastically improved, of course.   The same nice woman came in to replace a PFM crown that I placed in 2004.    The ceramic was coming off in typical PFM fashion.   We watched it for a number of years and finally replaced it when the interproximal ceramic broke and the contact opened.

The CEREC PrimeScan (and the Omnicam!)  has a great intra-oral camera function!  Use it!   It’s so easy, and it’s right there next to you!

 

The tooth was prepared with removal of the amalgam build up.    I call it “scuzz” but there was leakage everywhere and even under the amalgam.   It is the Achilles Heal of dental materials:  radio-opacity.   It’s hard to diagnose if you can’t see it! 

No way???    5:11 mill time with the new CEREC Prime Mill!    Just unbelievable after years of milling eMax.   

The final restoration was cemented with Fuji Plus RMGI cement.   Yes, I will cement eMax.   I’ve been doing it since I beta-tested eMax in the early 2000’s.  Critical components for success with this method:   prep design, occlusal reduction (of course,) and a close look at the occlusal patterns and habits.
