Transitioning to a Final Restoration: Traditional Methods vs iJIG

Subscribe to our YouTube Channel


Hey, it’s Chris from ROE Dental Laboratory and today we are talking full arch restorative workflows. There’s a couple different workflows we’re going to discuss. One’s a digital workflow that kind of brings it back into the analog world, but there’s some advantages obviously with the digital portion of that. And then we have a full analog workflow over here for the full arch transition into your printed tryin and your final zirconia. So on the right here, completely analog protocol. So patient full arch surgery is done, implants are integrated, and now we need to transition into their printed tryin or their wax up wax tryin. And then ultimately their zirconia final, but we need to establish a vertical and we need to establish passivity of the implant. So usually it’s down to about three appointments for this. So the first appointment, you’re going to send us the upper, lower and a bite depending on if they’re wearing a immediate prosthetic or not.

But we need upper and lower impressions. And then the next appointment is going to be a longer appointment. We’re going to send you back a screw down bite rim, screw down bite block. And obviously we’re going to establish vertical with this. And then we’re going to put our markings in here, our center midline cuspid lines, a high smile line in here. Give us some notches for a bite. And then we will also send you a fit verification jig. So initially you screwed this in, get your vertical, make your marks, unscrew that. Then you’re going to screw the verification jig in. And we are going to assure passivity here. So if it’s not passive, then you are going to section it at the area where it’s not passive and then re-lute that together. And then you’ll send these records to us. And from here we’re going to make a printed tryin or tryin, which is a prototype for the final.

But this appointment can be long and tedious for you and the patient because you’re doing a lot of screwing and unscrewing of these different devices in the mouth. So let’s go over to this side. This is one of our digital workflows. We have a couple different digital workflows that transition into your final, but this is called the iJig. And the way it works is the patient is wearing their immediate load prosthetic. So I don’t have that here with me, but we’ll, we’ll kind of see the workflows following that. So at the initial appointment for the immediate load prosthetic, we want you to unscrew the prosthetic they’re wearing and then take a tissue scan. So scan the healed tissue because we’re going to make, we want to make something that’s nice. And again, a prototype for the final scan, the healed tissue. And then you’re going to take a 360 scan of their prosthetic. We’re going to send you some analogs, some scan analogs. You’re going to screw ’em into intaglio of the prosthesis, right into the temp cylinders. Screw those in.

Then you take a 360 degree scan of the prosthesis. Next, you will unscrew the multi-unit abut analogs or the scan. Scan analogs, reseat the prosthetic, screw it down, scan the opposing, scan the bite from there that you’re done at that appointment. Next appointment is going to be the iJig seating appointment. So from there we fabricate the iJig and what it is, it’s a fit verification jig and the bite rim all in one and it’s a duplicate of the prosthetic they’re wearing, but it’s more idealized because now we have it meeting the tissue. So this is actually a prototype of your final. The iJig already comes sectioned for you. So what you’re going to do is remove the immediate low prosthetic that they’re wearing, seat your iJig, and screw each section in. Prior to doing that, you might want, we want a tissue reline. So you can either scan the healed tissue or you can put some trade adhesive on intaglio and to express some PVS in between the intaglio and the tissue to capture the heal tissue.

Again, if it needs to be captured, ideally we’re meeting the tissue perfectly with the iJig. Once it’s seated, you want to make sure all the sections are passive and then loot each section together. Give us an dial in the bite because that’s what’s nice about the iJig, it’s your screw down bite book and your fit verification jig all in one. So it’s replacing, it’s these two things all in one. So you’re only screwing it on screwing one thing. Screw it down. Take your bite reline impression if needed. Give us an opposing, send that back to us. From there, we are going to make a printed tryin. So this is kind of what the luted alluded together iJig looks like we have a reline impression. The sections are luted together. We have a bite, we have a posing, send it back to us. We’re going to go to a printed tryin and then into a final.

One thing you can do to speed this process up here is it’s called the iJig plus. So we can avoid the sectioned verification jig appointment, the iJig appointment. If you at the scanning appointment, the initial scanning appointment at the records, you go ahead and do, take your scans I discussed, and then take the immediate load prosthetic pop, some analogs in that, set it in stone, pour up a model. So now we can make this verification jig to that model. So now we have a passive model. We know it’s verified, we can make the jig to it. No need to send it section. So now you’re going right to your printed tryin, and then you can get to your final faster. So again, another advantage of the digital workflow comes back into the analog world, but overall, it can be a lot faster, especially if you pour that model with the iJig Plus protocol. Any questions on either our digital workflow or the traditional analog workflow? Leave ’em in the comment section below. You can always check us out At our website. We have an iJig section. We have an iJig plus section for all the records. And then if you could please subscribe to our YouTube channel. Thank you.
