The iJIG

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

What is the iJIG?

    • iJIG is a fit verification jig with teeth. 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.
    • The steps are simple. First, ensure that you ordered and received iJIG Scan Analogs from PROTEC – must inform PROTEC of the implant system. They are specific to this technique and can not be substituted. The first clinical step is to remove the appliance(s) from the mouth, scan the tissue and MUA’s and send to PROTEC. Then open a second patient event in the software and scan appliance with iJIG analogs attached outside the mouth, reseat the appliance, scan the opposing and bite and send. With this information, PROTEC creates the iJIG using special software.
    • Once completed iJIG is fabricated, sectioned, ready for luting and pick up.
    • Compatible Implants:
      • iJIG is compatible with most implant systems: Nobel, BioHorizon, NeoDent, Biomet 3i, Straumann, Hiossen, and Keystone
      • However, if you are restoring Zimmer, Implant Direct, Camlog, Astra, MIS, Straumann, Paltop, you must order OEM MUA replicas to scan the prosthetic. Simply screw them into the prosthetic and scan.
    • Must order OEM MUA Analogs for these systems:
      • Zimmer, Implant Direct, Camlog, Astra, MIS, Straumann, Paltop
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 PROTEC 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 PROTEC’s iJIG Scan Analogs ($29 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 PROTEC

Upload the case via PROTEC’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 PROTEC Fixed Full Arch Work Authorization and return to PROTEC. 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, PROTEC 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)
