“Veersing” Effect – How Intra-Oral Scanners Introduce Errors in Edentulous Jaws and Flat Planes

In the world of digital dental scanning, precision and accuracy are paramount. To shed light on the potential pitfalls and challenges faced by dental professionals, Dr. Armen Mirzayan of CAD-Ray has put together an eye-opening video. In this demonstration, Dr. Mirzayan explores the intriguing concept of The “Veersing” Effect and how it can lead to scanning errors when using digital dental scanners. We’ll delve into the video to understand the nuances of these errors, using examples from some of the leading brands we sell, including the Trios 5, Dexis 3800, and Medit 700. Each of these devices possesses its own unique features and capabilities, making them essential tools in modern dentistry.

Understanding Scanning Errors:

Scanning errors can have significant consequences in the dental industry. From inaccurate digital models to flawed treatment planning, these errors can compromise patient care and results. In Dr. Mirzayan’s video, we uncover the ‘Veersing’ phenomenon and its relevance to scanning errors. “Veersing” is essentially the involuntary loss of awareness of a digital scanner, causing it to not recognize its position and create errant or double images.

Additional Note: It’s essential to understand that in dentate cases, the properties of enamel can introduce errors. These errors arise from refraction, reflection, and light transmission through enamel. The asymmetric tooth morphologies can help your scanner stay on track. In edentulous cases, we face a different set of challenges related to the symmetric anatomy of the object being scanned, making it easy for the software to plot data points where they don’t belong.

Handheld vs. Desktop Scanners:

One of the video’s key takeaways is the difference between handheld and desktop dental scanners. Handheld scanners, like the ones we’ve featured, capture images and stitch them together to create digital models. Desktop scanners, on the other hand, take multiple views of a stationary object (also, with a wider field of view), resulting in higher accuracy and less room for errors. Understanding this distinction is vital in avoiding ‘Veersing’ and other scanning errors.

Examples of Scanning Errors:

Dr. Mirzayan demonstrates the potential for scanning errors with real-world examples from the video. These examples provide a visual insight into how ‘Veersing’ can affect the accuracy of digital models created with these scanners.

Preventing Scanning Errors:

To prevent ‘Veersing’ and other scanning errors, proper scanner positioning is crucial. Maximizing the field of view is key, as it allows for more accurate data capture. Additionally, considering the virtues of desktop scanners, which inherently provide multiple views of stationary objects, is another important step toward achieving precision.

Importance of Accuracy in Digital Dentistry:

The overarching message of Dr. Mirzayan’s video is clear – accuracy in digital dental scanning is non-negotiable. Avoiding scanning errors is a cornerstone in treatment planning, leading to better patient outcomes and more precise dental work, and steps can be taken to reduce the potential for those errors.


In a world where dental technology is constantly evolving, understanding and preventing scanning errors are paramount. Dr. Armen Mirzayan’s video is a valuable resource that highlights the nuances of ‘Veersing’ and scanning errors, providing insights for professionals to enhance their scanning processes. We invite you to watch the video and embark on a journey to a more accurate and precise dental practice.

AI Scanbody Match with Medit i700

In this video, we show how you to capture the healing abutment, the tissue profile after the abutment is removed, and then we image the scanbody while utilizing the AI feature of the Medit i700 to pick up all the data from the scanbody by matching the STL to the physical one during the scan

Advanced Features of the Medit i700 IOS That Separate it From All Other Scanners

Here is why the Medit i700 is the best intra-oral scanner on the market if you do any kind of implant restorations. There are so many options and tools that are leap years ahead of other scanners and their software. Medit can automatically identify the scanbody for you so you don’t have to do cartwheels and gymnastics to pick up all of the scanbody. This is in part 1 of the video.
For advanced users, we are sick of dealing with scanbodies and checking to make sure they are seated all the way and not binding on the tissue or bone, so we developed this technique of just scanning the fixture itself. It is not ideal just yet, but it will be the future, as the inside of the fixture is too shiny. i just used some old cerec spray to mask the topography for this demonstration.
oh, and really, no one else can show you how to milk that medit like can. we use it well beyond what it was intended for and frankly you are wasting your time and money with most others. contact Frank DeLuca, Frank Weinstein, Laura Geney, Nick Statly, Damien Bonner, Jonathan Acker in the US or Milos Gedosev, Mariangela Di Nato, Roddy MacLeod in Europe for more information

Scanbody Search in Meditlink Software

To use the Artificial Implant Suprastructure Identification Software to identify a scanbody, you have to understand how it is listed in the library.  It is not listed by the name of the implant company but rather the manufacturer that fabricates that implant lines scanbody.  For example, there are multiple choices for Nobel Active Conical Connection scanbodies.  The easiest way to find them is to search for the pre-loaded brands, but be aware of the routing abbreviations many companies utilize.  For Nobel Active, usually NB AC is used.

Then you must choose whether you are going to fabricate a Ti-Base or a Custom Abutment, and whether you are using  an intra-oral or extra oral scanbody.  The connection type (diameter) and the material (titanium vs. chrome cobalt) also must be selected.  Here’s a quick video that illustrates the selection process.  You must also consider if a 10 or 14 mm diameter blank is going to be used to mill the product.  In molar areas, a size 14 is preferred so that you can reach the outer most boundaries of your desired margins, whereas a 10 mm blank may be too narrow and small for a molar.
