In my many years working with both Windows and Mac-based software, crashes do occasionally happen.  I have experienced software crashing with CEREC.  There are several steps that can be taken to assure that valuable data or software design steps are not lost with the occasional software crash.  It is simply strategically saving at several steps during the software workflow.

My Crown Parameter portfolio for Primescan is similar to the last few versions of Omnicam except for one.  This video will review how my Parameter management has been impacted by Primescan.  

The minimal thickness parameters are now set to manufacture recommendations for each material used.  This will provide instant feedback with engineering "checks and balances" during the software design phase.

2020 will be a year of growth and excitement at the Klim Institute online CEREC training.  We have an evolving software and will see several new applications that will provide a full range of care options for our patients.  As exciting...new materials entering our CAD/CAM market this year.  

I am most impressed with MiYO, a liquid ceramic that is painted on our ceramics like a stain and glaze.  The results are magical.  This will bring our chairside aesthetics applications to a whole new level not yet experienced in our industry.

The Klim Institute Online will be adding two new channels this year... Full Mouth with CEREC and

This video will convey my three primary software design steps for posterior "bread & butter" CEREC dentistry. Software design efficiency is set up first and foremost with two preparation factors and capturing a compressed PDL bite registration.  My design efficiency will be determined by my design sequencing and selecting the tools that provide fast and purposeful desired design modifications.

This video is applicable for CEREC software versions 4.52, 4.61 and the lastest Primescan.  The workflow is the same for both Omnicam and Primescan users.

The Model Phase Screen tasks are automated, and working well in the current version of the software.  There are still a few checks and balances that I work through to assure occlusal and fit success.  This video is a must for viewing and is applicable for current Omnicam and Primescan users.

Primescan provides the dream scanning situation for inlays and onlays.  The best we have had yet in the years of CEREC upgrade scanning devices.  There is a caveat about which version of the CEREC software can best handle the two-piece implant restoration in the premolar or anterior zone of the mouth.  In the opinion of Dr. Klim, it is the 4.52 software which means we still need the Omnicam. This case review video will illustrate the planning and implementation to restoring an implant restoration on a non-ideal placed implant and creating the illusion of a smaller mesial-distal tooth using the combo of the Primescn and Omnicam.  To

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.
