The iJIG

The iJIG is a patent pending device used to easily, and digitally, transfer full arch records to ROE. If you have a digital impression scanner, iJIG makes record collection simple.

What is the iJIG?

  • iJIG is a fit verification jig and final prosthetic proposal all-in-one.  It allows the doctor to lute passive sections together in the mouth, equilibrate the occlusion, capture the bite, pick-up the tissue, and basically capture and send all the records needed to create a final or prototype restoration. It is an amazing device.
  • To create an iJIG, simply order our iJIG Scan Analogs and capture a digital impression and upload – watch the video below for the technique. Read below about iJIG Scan Analog compatibility.
  • The steps are simple (see the necessary records needed for the iJIG  below). Ensure that you ordered and received iJIG Scan Analogs from ROE – must inform ROE of the implant system. They are specific to this technique and can not be substituted.
  • Watch the second video below for how to manage the iJIG seating appointment with the patient.
  • Compatible Implants:
    • iJIG works with almost every popular implant system: Nobel, BioHorizon, NeoDent, Biomet 3i, Straumann, Hiossen, Thommen, Keystone, others
    • However, if you are restoring Zimmer, Implant Direct, Camlog, Astra, MIS, Straumann, Paltop, you must order OEM (original equipment manufacture – the implant company) MUA replicas to scan the prosthetic. Simply screw them into the prosthetic and scan according to our protocols.
    • Also, this second list of implant companies requires OEM parts to fabricated the iJIG and will increase the cost over 3rd party parts that are used on Nobel-compatible MUA’s. Call us to answer any questions on this.

Step 1: Seat the prosthetic

Ensure the prosthetic is seated on MUAs (multi‐unit abutments). Not compatible with Zimmer, Implant Direct, MIS, Camlog, Conelog implants. Must use these company’s OEM MUA model analogs to scan!

Step 2: Screw in analogs and scan

Unseat the appliance, screw down a ROE iJIG analog to each site on the restoration to be restored. Scan the arch with MUA’s as a first patient scan. Then, scan all the surfaces of the prosthetic with a digital impression scanner (All surfaces), and then reseat. Scan opposing arch and bite, and capture full face full smile photographs (close up full smile if photographs are dark).

Required records include:

  1. Extra‐oral scan of existing prosthetic with ROE’s iJIG Scan Analogs ($20 each)
  2. Intra‐oral scan of opposing arch and bite registration against existing prosthetic
  3. Intra‐oral scan of the arch – tissue and MJA’s (may need to send as second patient name)
  4. Photograph of full face / full smile if esthetic changes needed
  5. Provide exact implant brand, system, and platform of each site!

Step 3: Upload the case to ROE

Upload the case via ROE’s web site, or submit via your digital impression portal. Order an iJIG and must provide the implant brand and size.

Step 4: Receive the iJIG

Add tray adhesive to the tissue side of each section. Screw down each section using the clear transfer holder. Ensure all sections are fully seated and passive ‐ capture an X‐Ray to confirm! Adjust if needed to full passivity. Lute all sections with GS Pattern Resin, VOCO Quick‐Up, acrylic, or Duralay. Flow medium or heavy body polyvinyl impression material between the iJIG and the tissue (reline impression). Equilibrate, capture a bite, opposing, photos if needed, and make marks on the iJIG where esthetic changes are to be made.

Step 5: Complete the paperwork

Complete the ROE Fixed Full Arch Work Authorization and return to ROE. Must indicate how you would like interaction of the final with the ridge: Hygienic design with ridge contact / high water design / other please explain. Order a Printed‐Try prototype. If the iJIG is nearly perfect, you may order the final restoration.

Step 6:  Changes / Adjustments

If esthetic or other changes are needed, ROE will create a resin Printed Try-In for final approval. This is a monochromatic chairside try-in verification for final. If there are more changes to be made, return with instructions, again using this Rx.

Step 7: Seat the final restoration

Seat final restoration (Zirconia, NanoTi, NanoTrinia, New Crystal Ultra)
