IPS Ivocolor is a universal stains and glaze assortment for the individualized staining and characterization of ceramic materials. The range of products has been coordinated with the layering, press and CAD ceramics from Ivoclar Vivadent and the zirconium oxides from Wieland Dental and can be used regardless of the CTE of the ceramic. Due to the optimized sinter temperature of the newly developed glass, optimum esthetic results can be achieved irrespective of the ceramic substrate. 

The newly developed composition of the pastes was optimized with regard to the application behaviour and the firing results. The gel-type structure of

I am often asked the question, why is there sensitivity after e.max restorations are placed. Even when using a good adhesive primer.  Watch the video and find my perspective.  In general, the adhesive systems in our current market portfolio perform very well and have significantly diminished post cementation sensitivity.  So why may we occasionally observe this event in our restorative clinical theaters.  For Bluecam and Omnicam users, it comes down to over drying and desiccating the dentin prior to imaging.  In this video, I will review some pointers in getting around the imaging issue.  I do agree, the dryer the image field, the better

I do appreciate the all zirconia restorations and provide quite a number of them as a treatment option in my clinical theater.  The primary benefit of the all zirconia restoration for me is the conservative crown prep and biomechanical “muscle” material behavior.  In the next year, we will find an abundant of new brands and translucency options being introduced to the market.  We will need to decipher recommended prep style and reduction demands for each brand (strength). 

The prep reduction metrics will be determined by brand and strength.  They are not all the same.  For instance, the ZirCAD LT recommends 0.6 minimal thickness

This video will document how to remove a bonded e.max crown.  This can be a tough exercise.  Using the right burs is critical.  View Video

The "WAVE" cementation technique will ease cement cleanup.  Some cement brands are designed for the wave technique.  Variolink Esthetic dual cure is one of them. This video will walk through the flow of the wave cementation technique from soft tissue conditioning through the cement cleanup stage.

It is simple to add a contact when needed to zirconia with GC Luster Paste.  Infact, this is now my go to method for all my ceramic restorations, (VITA ceramics, Empress, and e.max).  It is very fast and predictable.

Zirconia cementation is simplistic. The post-cementation caveat is the interphase between the cement and the internal surface of the Zirconia crown.  Zirconia is slick to cement.  Conditioning Zirconia with a metal primer is only effective if the phospholipids can be removed.  Ivoclean removes the
