Just taught a class with one of the attendees who has had the CEREC for several months say he is achieving incredible margin mills as good or better than what he received from his lab. So how do we achieve milled margins that are smooth without micro-chips, particularly on e.max? Can we mill feather margins without micro-chipping? Oh yes, we can! In this video, Dr. Klim will review the strategy behind milling seamless margins, even thin feather margins with NO CHIPPING.

Even with the multi zirconia options of Katana and ZirCAD Multi, in my hands, infiltration is the simplest and most efficient way to enrich the cervical zone color and modify cervical saturation needs. And with just one firing...sintering. This video will share material recommendations and methods.
The method works on all zirconia brands.
- ZirCAD LT Colouring liquids (very forgiving)
- Katana STML
- ZirCAD Multi

With zirconia, I use glaze and stain only for subtle highlight surface characteristics. For this process, Ivocolor by Ivoclar works well on all the zirconia brands, particularly the multi ones such as Katana STML, ZirCAD Multi, and the coming ZirCAD Prime. This video will demonstrate the zirconia preparation required for glaze addition and then glaze/stain applications creating subtle surface enhancements.

Finishing zirconia when it comes out of the milling unit is referred to as zirconia in the green state. There are a few steps that can be taken to really improve the surface quality of the green zirconia, and once sintered will save finishing time. The technique in this video is applicable to the zirconia brands in our CEREC clinical theater (ZirCAD LT, ZirCAD Multi, Katana STML, CEREC Zirconia, and InCoris).

Texturing and luster polishing a ceramic or composite will create the finishing touch for restorative blend harmony. Each case is often unique. In CAD/CAM e.max dentistry, we shape and texture before crystallization. This works most of the time, however, occasionally when fitting the ceramic in the mouth, further texture and shape tweaking are desired. This video will review the burs and polishing for providing texture and luster polish on a crystallized e.max restoration.

The CEREC community is experiencing an exponential addition of new CAD/CAM materials. The polymer material category is one of the growing ones: this video will review applications and a polishing technique for the polymer Tetric CAD. The finishing technique conveyed in this video will work for other polymers such as Lava Ultimate, Cerasmart, Enamic, and other like materials.

One advantage of aesthetic multi-gradient zirconia like Katana STML, ZirCAD Multi, and ZirCAD Prime is the ability to polish and blend right out of the sintering furance. This video will provide the steps for post sintered aesthetic zirconia polishing using the JK04 using the Meisinger Zirconia Polishing Lab Kit.

Katana STML is the first of the available chairside multi-gradient aesthetic zirconia options for chairside CEREC milling. The sintering time in the Sirona SpeedFire furnace is in the 18:00-minute range. This is an incredible fact! A significant advantage for a multi zirconia application is that the aesthetic gradient is already in the pre-milled block. All we do is choose the matching color shade, mill, and polish after sintering. This video will demonstrate the effective finishing steps for Katana STML using the Klim Institute Meisinger Zirconia Lab Kit JK04.
