The clash of the titans are in full effect. We are not smart enough to understand all the dynamics of patented software and hardware. While we let the manufacturers sort it out, we wanted to demonstrate how the new mandibular jaw movements are captured in Meditlink

Why is this a significant step?

There is a concept in digital dentistry that is called “mixing good and bad data”. What you have to appreciate is that two different objects can’t occupy the same space in the same 3D model. The clinical example of this is when you pack 2 cords, image the margins, then remove the top cord and image the preparation some more.
This introduces a lot of errors and distortion at the margins. You either have to image with 2 cords retracting the tissue at once or take top cord out and the image the only remaining cord. This is a habit that has carried over from analog that most users can’t seem to get past and often get frustrated with the results. See the video for a detailed explanation
In this video we demonstrate for new and potential users of digital dentistry a implant restoration where the dynamic bite is captured. We initially imaged the upper and lower jaws with 2 bites. Then we captured the dynamic bite and the returned for the jaw scan with the scanbody. There are many ways to approach this but this sequence we have found to be easiest for new users to digest.
The scanbody was captured after the bite because it usually is taller than the adjacent teeth. There is a chance you may injure the patient if you don’t follow the proper sequence
