The Scans Needed for a Grammetry Restorative Case

This video will show the scans needed in order to complete a Grammetry restorative case. Now, in this case, we are going to have a hybrid that is scanned extraorally without a wash impression. Instead, we’re going to scan the tissue and the MUA’s. Let’s go through the scans. This is the first scan: scan the teeth; upper, lower, and bite. We just need the teeth in this scan, because this is used to bring in the subsequent scans. Next, the prosthesis is removed and scanned extraorally with the OptiSplint scan analogs plugged into the copings, which are Nobel-compatible copings. You’ll notice that there is no wash impression. For this case, we are not going to use the intaglio of the prosthesis to design the prosthesis.

Take a nice 360 scan, get a lot of detail, and take a lot of time with this scan. We want to get the teeth perfectly captured and we want to get the scan bodies. Then scan the tissue and the MUAs. This is taken from our iJIG technology that we can bring into the whole stack to design the intaglio of the prosthesis. Simply scan; you don’t have to get the vestibule, we just need the ridge. Carefully capture the ridge, all the tissue, and the multi-unit abutments, and we can bring this into the software. This scan was captured with an Itero. We might have a little challenge with tissue, as it’s not yet on our recommended scanners list, but you can try it for yourself. That’s how this was scanned. And it’s actually a very impressive scan.

Then finally, scan the OptiSplint extraorally. This one was luted intraorally, and the doctor did a nice job of intraoral scanning. The luting material is just on the horizontal arms of the OptiSplint; that’s the part that jets out here into the palatal area. The metal honeycomb frame is set on each one of the horizontal frames and luted, and you can see there’s a nice contiguous flow of material. Here’s the OptiSplint removed and put on the bench top, where it is scanned with the iOS scanner. It’s a very nice scan. Now, obviously, there are areas where this could have been scanned better, to try and get the full part of the scan body, because the round here is the scan body, but we’ll be able to make this register. And with that, those are the Grammetry scans needed for a restorative case without a wash impression, and adding the tissue scan with the multi-units.
