One of the features in CEREC I appreciate the most is designing and creating customized abutment/crown one or two piece restorations. CEREC 4.52 has been a smooth acquisition, design, and production process for implant restorations. Have been very pleased! One hassle for implant/abutment in CEREC 4.6 has been minimal thickness defaults and not being able to modify the metric settings for unique implant design and milled cases. As a result, some cases cannot be milled. This hassle in 4.6 has been frustrating for me. However, I did keep 4.52 on my system which has been seamless for implant design and production. So my go-to CEREC

Occlusal Offset will impact material thickness milled and occlusal calibration. This video will discuss how to arrive at an Occlusal Offset that is properly calibrated for your CEREC system and assure proper occlusal material thickness and occlusal contact firmness.

Verify the model mounting before moving to the Design Phase. I have learned this valuable lesson. When the mounted models can be verified, the design process, parameter settings, and the final mill can be trusted. Occlusal verification is one of the critical check factors to avoiding occlusal adjustments of the final restoration(s).

Number one reason to upgrade to 4.6 is the improved interpretation for rendered margin clarity. Also, there is improved responsiveness to acquiring ceramics, including e.max. The camera still struggles with shiny alloys. I have never found this a problem; I apply Optistray to decrease the reflective surfaces and acquire an incredible scan quality. This video will highlight the CEREC 4.6 Omnicam scanning qualities and my secret for staying on clinical schedule.

I recommend uploading CEREC 4.6 for just the scanning and margin clarity features. However, keep 4.52 around. There are historical trends for software glitches to be present with new software versions. This videos will share several hacks I use to get through some of the 4.6 glitches.

The CEREC 4.6 workflow is very similar to 4.52. The most significant upgrade from 4.52 is the camera scanning proficiency. The camera also picks up shiny surfaces such as ceramic and gold much better than in prior software versions. The model rendering is faster from the Acquisition screen and all the steps in the model screen are automated including setting Model Axis and Drawing Margins. I have found it is better to disable the auto margin calculation unless the margins are high and dry. For larger cases with multiple preparations, the software has a tendency to crash. The software performs much better when margin calculation is

I have often received calls from CEREC offices and have had Patterson Dental sent new CEREC owners to my educational center who are struggling with chairside CEREC integration. Going clear back to dental school, there are times that I have struggled with new clinical applications. I have found that integration problems are usually still solved with going back to the basics for the particular application being accomplished. I have found this to be the case with most CEREC integration issues. The beauty of CEREC is that is will refine our prep skills by showing the user where refinement needs to happen. Labs have been dealing with our

This video shows my full approach for taking upper and lower full arch scans and mounting them with a bilateral buccal scan. This has been the one Achilles heel with the chairside software until now. Now that we have auto-mounting in the Acquisition screen with the buccal scan, we can now get in both sides of the arch for a full seating of the models. Ninety percent of all impressions including study models are taken with the chairside software in my practice. Technique for the full arch scan is critical to make this approach work.
