A lot of our users are migrating to SSD Drives which greatly speeds up processing and graphics rendering in intense software applications. When you are capturing scans with the Medit i500 you can quickly fill up your hard drive with law videos (which is technically a series of thousands of images) and when you process the case, the data is converted into small 30-50 MB size digital models

In previous versions of the software that data was only stored on your local machine, which meant you could not log into another computer to add or edit your live video images. You now can sync the data through the cloud so you can access it anywhere, or you can delete the raw footage from the preview screen. In previous versions you would have to search hidden folders to find this data, but now it is readily available and you can dump the data with one click. You do not delete your models in this situation.

Titanium blanks are the hottest topic in digital dentistry in 2019. A lot of new milling machines can mill emax, zirconia, and custom metal abutments.

One of the parameters to keep in mind when milling them is the diameter of the screw access channel. Most CAM will carve them out but leave a lot of finishing processes remaining.

We’ve tested quite a lot of mills with the imes icore coritec one and the milbox cam software. If you set the settings to 2.5 mm’s , you can pee off the excess sprue material with just finger pressure, dramatically reducing the free hand work that you would have to do.

The pin diameter at object and at material under 2.5 mm’s will give you inconsistent results.

Most scanners will export the jaw model and the scanbody model separately but a new feature on the Medit upcoming software will let you export them as individual models or as a single merged model.

There are design advantages to both scenarios based on the practitioners skill level!

There are numerous ways to quickly check a model before taking it to a design software. Windows comes with at least 3 such free software. Another one to have handy is called 3dviewer.net to let you verify models really quickly

Here is the same crown milled in detail in 30 minutes with the additional 0.6 mm drill finishing the intaglio and the occlusal anatomy

Intra-oral scanning for immediate extractions and immediate denture fabrication. Upper and Lower dentition were digitally extracted. The Vertical Dimension and tooth position was preserved for the lab to design the prosthesis.

So easy to manage this situation for immediates as opposed to taking a physical impression and hoping not to inadvertently extract mobile teeth. Plus, the lab knows how to mount the case properly.

Repairing hybrids can be a nightmare. At CAD-Ray, we recommend that you fabricate two sets of the prosthesis so you can swap them out at recall for repair work, or so do you don’t have to ask a patient to part ways with it when a part breaks off from long term function.

Here, we repaired it by milling a restoration that is a mirror of the Right Central Incisor.

In our 2 day hands-on course, we make sure our doctors get comfortable with full arch scans in speedy and accurate fashion. One of the greatest feature of the Medit iScan software is the reliability map. Watch how we image this full arch; every camera position and movement serves a specific purpose, which is to plot as much data on the X, Y, and Z plane so that the camera and software can always recognize where it is in reference to previous data captured.

Note how we move the camera back to a position in the arch to reinforce the fact that it is “on track”. The more data it recognizes the more accurate it can be in full arch imaging. This is true for all intra-oral scanners and the same principle can be applied to all of them. This should also explain to you why imaging an edentulous area is harder to do with all scanners- there is less data (or no data) on a vertical plane for it to recognize and to use a reference frame.

There are numerous reasons for this. Clinically, you want to scan the jaw with the implant without the scanbody in place so that you can have access to the contact areas of the adjacent teeth. More importantly, the scanbody can be taller than the adjacent teeth, which would throw off the buccal bite capture when trying to relate the upper jaw to the lower jaw.

When you image the scanbody in the the Medit iScan software, the data is ignored for the occlusion calculation. When you, or a lab design with the scanbody, they also have to “feed the CAD Software” the right information. 3Shape software requires that 3 models be imported in a specific sequence: the jaw, the jaw with the scanbody ALREADY merged, and the opposing. If the designer is a novice, they may struggle with this and reject your case. There are numerous work arounds and easy fixes for this, but a good practice is to image them separately for all the benefits outlined above.

This article is for advanced users, where we detail a quick and easy scan, design, and mill. While the patient is anesthetized, the preop images are scanned. Excess data is removed as all it does is slow down processing. The prep catalog box is clicked, and the same model appears there. This is a source of confusion for many new users. Therefore, we recommend that you immediately crop out the area to be prepared so you don’t get the catalog boxes confused.

As an advanced user, you may be familiar with the reliability map. Here, we demonstrate how you can use the reliability map to capture your margins. Once the data turns green, this means you are done creating the model. This does NOT mean you captured your margins correctly. You could have just as easily captured tissue that is hiding your margins. The live view, in the bottom right corner, is where you can clearly asses if you have direct line of site to your margins!

Furthermore, as an advanced user, you may realize that it is NOT necessary to capture data below the height of contour of the adjacent teeth as you will not be making contact with that area! You can see in the try-in video at the end of the article how the restoration fits well to the contact area of the neighboring teeth even though the data was not captured.
