What records does ROE need, and how do the records techniques work?

The NobelProcera process is prototype-driven: you capture records of the patient's existing screw-retained prosthesis, ROE fabricates a prototype try-in for you to verify, and then the final is produced. The right records technique depends on whether the case is entirely on multi-unit abutments or includes direct-to-implant sites.

Pathway A, all multi-unit cases: When every site is on a multi-unit abutment, the fully digital iJig technique can be used to capture a verified record digitally, which is the most streamlined route.

Pathway B, direct-to-implant or mixed cases (Flasking Technique): When the case includes direct-to-implant sites, a physical record is captured by duplicating the existing screw-retained prosthesis. You will need PVS impression material, MUA analogs, a denture flask or cup, casting stone, lab putty, and a set of smile photographs. The core workflow:

Step Action
1. Photos With the patient standing, take a full-face full-smile, a full-face exaggerated smile, and optionally a full-face profile smile.
2. Scan or impress tissue Remove the prosthesis and immediately capture the tissue and the multi-unit sites with an alginate or IOS scan of the full arch (this also picks up some implant positions), plus the bite.
3. Seat analogs Attach the analogs to the prosthesis: iJig analogs on the multi-unit sites and conventional implant-level analogs at the direct-to-implant sites. A four-implant mixed arch ends up with four analogs total.
4. Set in stone Fill a denture or splint cup with casting stone and set the prosthesis and analogs into it, kept slightly raised above the stone. Let it fully harden (roughly 5 to 20 minutes).
5. Verify model Unscrew to produce a verified analog model, which in some situations can go straight to final.
6. Putty the intaglio Knead lab putty (with accelerant) and encapsulate the prosthesis on the model, pushing in to capture the intaglio; once set, pop it off.
7. Return and finish records Unscrew the prosthesis and deliver it back to the patient, then take a bite and an opposing impression, model, or registration.
8. Ship Send the analog model, putty shell, PVS impressions, photos, and bite or opposing records to ROE, which fabricates the prototype (sometimes the final).

Note that the impressions in step 2 can be taken digitally, but the appliances still ship to ROE for mounting. The resulting prototype (often a 3D-printed Printed Try-In) lets you confirm esthetics, occlusion, phonetics, and fit before the zirconia is milled; see The Printed Try-In. For the full protocol, download the Ultimate Restorative Protocol Guide eBook, and see the product page's "Records Required for a Full Arch Bridge" and "Capturing Records with a Flasking Technique" videos.
