The Dimension Tool provides an efficient and simplistic approach to modifying the buccal-lingual, mesial-distal, or the full size of the proposed restoration. The concept is similar to the Pre-positioning feature in the SW prior to 4.0. Released in the 4.0.3 Service Pack. View Video (located in CEREC Liftoff 4.0 Integration Chapter)

Recently, several doctors have asked the following question:
“I had a crown de-bond, the patient has the crown but it has resin cement still bonded to the inside of the crown, what do I do to remove it?” The simplest solution is to place the crown on a honey comb tray and fire in a furnace for about 5 minutes. Resin will burn off during this

IPS Empress CAD is leucite glass ceramic offering three translucencies (Low, High, and Multi) that offer excellent esthetics to compliment high strength and over 20 years of clinical success in press and CAD/CAM technology. A feature of Empress CAD is the increase in fracture strength when glaze firing the final restoration. The chart below shows the fracture strength of Empress CAD when milled, milled & polished, and milled & glaze fired. A glazed

The quality of mill and fit using the CEREC 4.0 bridge application is outstanding. I use this approach when the clinical demands require a longer lasting bridge than a 2-3 week turnaround time. This tutorial video in chapter 4 will review the finishing steps I take once the bridge is out of the milling unit.

Cleaning an IPS e.max CAD restoration removes lubricating oil used during the milling process. While oil is needed to cool the cutting tools and ceramic, oil incorporated on the prep may affect the bonding process or remaining on the crown may affect the the glaze. When removing the crown from the mill and if it is tried in immediately, oil may be introduced to the prep which may negatively affect the bonding process. If utilizing a

When treating all-ceramic, CAD/CAM owners will need to use hydrofluoric acid to create an etch pattern in order to create a surface to adhesively bond to. Different materials have different times to etch:
IPS Empress – 60 seconds with 5% hydrofluoric etch
