The Records Required for a Grammetry Restorative Workflow

This video covers the records for the Grammetry restorative process. The first scans that you need to capture are the upper, the lower, and the bite, along with some of the tissue. This is going to be a maxillary restorative case, which means the patient walked in with a prosthesis; the prosthesis is on multi-unit abutments and they’re Nobel-compatible. So scan the upper, lower, and bite, and grab some tissue. That way, you know that you have as much of the prosthesis as possible. In this case, there’s some missing here, but that’s okay because we’re going to scan the prosthesis out of the mouth.

Then, if your scanner will allow you to, turn off the opposing, scan the prosthesis 360-degrees outside the mouth with the Grammetry scan analogs, or our iJIG scan analogs, and it should allow you to take what you scanned already in the mouth, and then continue scanning around the arch. It will pick up where you left off scanning in the mouth. All you have to do is add the intaglio. If not, just hold the prosthesis in your fingers and scan it 360. This is what it should look like on your screen, and this, combined with this intraoral opposing, is uploaded to us. You will also have taken the OptiSplint out of the mouth and will have scanned it on the table, not in the mouth. You don’t have to scan it 360. This is a really nice looking scan, but really all you have to do is scan the occlusal surface carefully, scan the middle, then go out to each site, and return back to the middle. You can see some of this is not picked up here; that’s okay, we’re going to use this entire area here.

The OptiSplint scan will be brought back into the rest of the scans, and you will merge them with the prosthesis scan like so. In this case, we will use the intaglio as the tissue, and based on that we will design a prosthesis and either send it to you to print for a try in, or we will fabricate the prosthesis here at the lab. Just remember, this step will be very important: if the intaglio of the prosthesis is not ideal, you have tissue gaps, or anything going on there, then you will also want to capture a impression of the tissue and the multi-units. We will bring it into this stack of scans and we will adjust the intaglio of the prosthesis so that we meet the tissue exactly how you want, and having it be hygienic. And that is the Grammetry restorative process.
