Using the CT as a Remount Jig If You Have Lost The Vertical Dimension For Some Reason or Another

At CAD-Ray, we have now designed over 20,000 implant cases since 2013. One of the most common requests we get is from doctors doing full arches and their desires to reduce the conversion time. A simple thought to keep in mind is that A LOT can be derived from the actual implant plan, even if you don’t do the surgery guided. You can extract the digital implant positions and fabricate temps and based on your level of experience, your conversion / temporary time can drastically reduce.

Another very helpful matter to keep in mind is a concept we preach a lot at our courses. It deals with relating models to each other, both automatically and manually. This can be a CT scan to an intra-oral scan, or a pre-op to a post op. You just have to find redundant landmarks for the software to merge the models together. One thing to keep in mind, particularly with the Medit i500 is that when you merge models to each other and process it, their relationship to each other is preserved.

There is a lot of benefit that can be derived from that. For example, in this video, we have the dicoms converted to surface STL’s which is very easy to do. We also have the intra-oral scan merged to that stl file. You can digitally extract the teeth and do bone reductions, and if you are ever in a bind where you lost track of the vertical dimension, you can use the jaws as the means to related the preop to post-op. Or you can even use the nose if you are really desperate.
