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.

One of my clinical fascinations is technological advances that will streamline procedural flow and proficiency.  Last year, we introduced the LiteTouch Er:YAG laser to the practice, primarily for removing and upgrading e.max veneers. There are many other soft and hard tissues applications this type of laser brings to the clinical theater.  This video is about repairing a margin with caries on an e.max bridge placed over ten years ago. There are many benefits to removing diseased tissue with a Er:YAG laser:  calibrated for selective caries removal, antibacterial activity, debris removal without producing a smear layer, surface

I don't see too many MC XL CEREC tower communication glitches.  But it did happen today with the last patient of the day!  I heard the milling unit spinning without the familiar bur-on-porcelain sound.  I have experienced this more since going to RF connection from WiFi.  Fortunately, I have a second milling unit and proceeded with a normal mill while the first milling unit struggled. After 30 minutes we aborted the mill.  So what is the solution if your office only has one milling unit when communicational glitch occur?

Part one video in BioJaw anterior design series. The way I save time in my anterior design theater is to go into the case preplanned with a wax-up which I now do in inLab, print the model and use the wax-up as a reduction guide and basis for making provisionals when needed.  Time-saving comes from certain preparation reduction protocols for the case and then propose and refine with BioJaw, still using a BioCopy component to guide the BioJaw placement.  One thing unique to this case review is the strategy used to block out a dark root.

This video is Part II for the conservative CEREC restoration(s) and will demonstrate the Primescan software workflow. The Primescan is the latest Dentsply Sirona scanning system and provides the scan ease and required detail that a conservative preparation style and mill requires.  As a result, the software design workflow has been simplified with assured precise fitting restorations.

When is the conservative CEREC restoration indicated in our treatment portfolio and how does the Primescan handle the conservative preparation scan, design, and mill compared to Omnicam and Bluecam?  Unless a crown is being removed for an upgrade, preserving tooth structure with an onlay or inlay can be the optimal way to go.  The first part of this video will review four criteria for a conservative restoration and sets up the case review for Part II, the incredible Primescan for scanning conservative preparation design--the best of both Bluecam and Omnicam is now in the Primescan.

Sometimes it happens, software crash!  These are issues we occasionally need to work through, particularly with new equipment or software rollouts.  There is no exception for Primescan.  This video is about one of those incidents.  I really had to go after due diligence to save the case.  Fortunately, when I do a CEREC workflow with multiple units or that is unique, I have a habit of saving the case (Save AS) before starting the software design flow.  Having more than one file for a case can save the day!

Since the CEREC 3.85 software version, BioCopy anteriorly has not been smooth as I would like to see it!!!.  When BioCopy is proposed, often the proximal and cervical zones are concaved and require virtual wax modifications to get the case ready for the mill. The primary reason I prefer BioCopy is to go into the case preplanned for closing the emotional side of the case (emotional closure) and having a preparation guide.  BioCopy is a natural flow for design having already closed the case with a mockup or transitional (provisionals).  

BioCopy has been one of the greatest advantages using a digital platform; precisely reproducing

I miss the trackball and keypad with the Omnicam tower.  For the Primescan, I am using a wireless mouse.  In my hands, I have found the wireless mouse is faster than the touch screen and touchpad when in the design phase screen.

The Incisal Variation tool provides the finishing touch and last tool application right before milling anterior restorations.  I really like this tool!  Understanding the principles behind the primary, secondary, and tertiary labial anatomy will help when applying this tool.  This feature of the software will initiate the primary labial contours.  Let find out how the Incisal Variation tool works!  This video is applicable to 5.0, 4.5, and 4.6 software.
