iJIG

Our patented iJIG system (Patent no. 11589963) combines fit verification and final prosthetic proposal into a single device that transforms your full arch digital workflow from multiple complex appointments into a streamlined process.

Using your existing digital scanner and our specialized scan analogs, we fabricate a sectioned duplicate of your patient's prosthesis that allows you to verify passive fit, lute sections together intraorally, and capture all necessary records—including implant positions, tissue contours, vertical dimension, and occlusion—in just one appointment.

Compatible with all major implant systems, the iJIG eliminates traditional bite blocks and multiple try-ins while giving you the flexibility to go directly to final zirconia or through an optional printed try-in stage.

This innovative approach reduces your full arch cases to as few as three appointments, delivering predictable, passive-fitting results while enhancing both patient comfort and practice efficiency.

Clinical Benefits of the iJIG System

Streamlined Appointment Schedule:

Reduces full arch cases to as few as 3 appointments
Can skip the printed try-in stage and go directly to the final restoration

Comprehensive Single-Appointment Record Capture:

Captures implant positions, tissue contours, vertical dimension, and occlusion simultaneously
Eliminates the need for traditional bite blocks, bite rims, and multiple impression procedures

Enhanced Accuracy and Verification:

Sectioned design allows passive fit verification before final commitment
Digital duplication maintains proven vertical dimension from the patient's existing prosthesis

Universal Compatibility:

Works with existing digital impression scanners (no additional equipment required)
Compatible with all major implant systems

Functional Patient Testing:

Provides a working prototype for patient test-drive and approval before final fabrication
Allows intraoral luting, equilibration, and immediate functional assessment

The iJIG system is compatible with most major implant platforms; however, certain systems require original equipment manufacturer (OEM) parts for both scanning and fabrication.

Standard iJIG Compatible Systems:

Works directly with Nobel, BioHorizon, NeoDent, Biomet 3i, Hiossen, Thommen, Keystone, and other Nobel-compatible multi-unit abutments
Uses standard 3rd-party scan analogs and fabrication components

OEM Parts Required Systems:

Zimmer, Implant Direct, Camlog, Astra, MIS, Straumann, and Paltop require original equipment manufacturer (OEM) MUA replicas for scanning
Screw OEM replicas into prosthetic and scan according to standard protocols
OEM parts are also required for iJIG fabrication, resulting in a higher cost than standard Nobel-compatible cases

Important Notes:

Specify the exact implant system when ordering - critical for proper analog selection
For mixed implant cases, identify which implant is at each position
Contact ROE with questions about specific implant compatibility or cost differences

What is the iJIG system?

A patented device (Patent no. 11589963) that combines fit verification and final prosthetic proposal into one appliance
Allows digital transfer of full arch records through your existing intraoral scanner
Serves as both a comprehensive record-gathering device and a functional prototype

How does iJIG differ from traditional full-arch workflows?

Eliminates the need for traditional bite blocks, multiple try-in appointments, and complex impression procedures
Captures implant positions, tissue contours, vertical dimension, and occlusion simultaneously in one appointment
Reduces full arch cases to as few as 3 appointments

What equipment do I need to use iJIG?

Any digital impression scanner (compatible with most IOS systems)
ROE's specialized iJIG scan analogs (must be ordered from ROE)
Standard clinical materials for luting sections together

Is iJIG suitable for all full-arch cases?

Designed specifically for fixed full arch restorations on multi-unit abutments
Works best when the patient has an existing prosthetic that can be duplicated
Not suitable for immediate load or cases without an established vertical dimension

Which implant systems work with iJIG?

Standard compatibility: Nobel, BioHorizon, NeoDent, Biomet 3i, Hiossen, Thommen, Keystone
OEM parts required: Zimmer, Implant Direct, Camlog, Astra, MIS, Straumann, Paltop
Works with virtually all major implant platforms with appropriate components

What's the difference between standard and OEM compatibility?

Standard systems use 3rd party scan analogs and fabrication components (lower cost)
OEM systems require original equipment manufacturer parts for both scanning and fabrication (higher cost)
Both deliver the same clinical results, the difference is in component sourcing and pricing

Why is it critical to specify my implant system?

iJIG scan analogs are system-specific and cannot be substituted
Wrong analogs will result in a poor fit and inaccurate records
Mixed implant cases require the identification of each implant position

What information do I need to provide when ordering?

Exact implant system for each position
Clear notation that this is an "iJIG case"
For mixed systems, specify which implant is at each location
Any special requirements or modifications needed

How do I scan for an iJIG case?

Event 1: Remove prosthetic, scan tissue, and MUAs only (no scan bodies)
Event 2: Attach iJIG scan analogs to prosthetic, scan 360 degrees extraorally
Event 3: Remove analogs, reseat prosthetic, scan opposing, and bite registration

What are the key scanning tips for success?

Clean temporary cylinders thoroughly before attaching scan analogs
Scan one analog at a time when possible to avoid confusion
Ensure complete 360-degree capture of prosthetic with no missed areas
Take a broad bite registration for better manual alignment if needed

Can I use any intraoral scanner?

Yes, iJIG works with all major IOS systems, including CEREC, iTero, Trio, and others
Some specific scanner limitations exist (we'll provide details for your system)
The key requirement is the ability to scan prosthetic extraorally with attached analogs

What if I make scanning errors?

Contact ROE immediately for guidance on re-scanning protocols
Most scanning issues can be resolved with technique adjustments
We can provide real-time support for challenging cases

What happens during the iJIG seating appointment?

Receive sectioned iJIG from the laboratory
Seat each section individually and verify passivity
Use dental floss to ensure sections aren't contacting
Lute sections together with appropriate material (Stellar, GC Pattern Resin, etc.)
Equilibrate occlusion and capture bite registration
Take a reline impression if tissue adaptation needs improvement

How long should I plan for the iJIG appointment?

Typically 45-60 minutes for seating, luting, and equilibration
Additional time if significant adjustments are needed
Less time than traditional verification appointments due to pre-established VDO

What if the iJIG sections don't fit passively?

Remove individual sections for adjustment
Modify sections to eliminate contact points
Ensure MUAs are properly torqued before re-seating
Contact ROE for guidance if significant modifications are needed

Can I skip the iJIG appointment and go directly to a printed try-in?

Yes, by creating an analog model during initial scanning
Place prosthetic with analogs in stone model and ship to ROE
We'll fabricate a printed try-in instead of a sectioned iJIG
This option saves one appointment but requires chairside model-making

What materials work best for luting iJIG sections?

Stellar dual-cure resin (our preferred choice for fast setting)
GC Pattern Resin or Duralay (alternative options)
Any near-zero shrinkage material suitable for intraoral use
Avoid materials with high shrinkage that could affect fit

How does iJIG improve my practice efficiency?

Reduces full arch cases from 7+ appointments to as few as 3
Eliminates the need for custom trays, verification jigs, and multiple try-ins
Provides a functional prototype for patient test-drive and approval
Streamlines record transfer with comprehensive digital capture

What records does iJIG capture in one appointment?

Precise implant positions through digital scanning
Established vertical dimension from the existing prosthetic
Tissue contours through reline impression
Occlusal relationships through bite registration
Patient-approved tooth position and aesthetics

Can I go directly from iJIG to final restoration?

Yes, if iJIG fits perfectly and the patient approves all aspects
Many experienced doctors skip the printed try-in stage
Depends on case complexity and your comfort level
Printed try-in is always available as an additional verification step

How does iJIG ensure accurate final restorations?

Digital duplication maintains proven vertical dimension
Sectioned design verifies passive fit before commitment
Comprehensive record capture eliminates guesswork

iJIG Seating Appointment

iJIG + Records for Fabrication

Workflow Steps	Instructions	Images
Step 1	Take the following photos with the patient standing up: Full-face full-smile Full-face exaggerated smile Optional: Full-face profile smile
Step 2	Remove the patient’s prosthesis. Seat scan analogs passively onto the intaglio side of each of the temporary cylinders of the prosthesis.
Step 3	Scan the tissue and MUAs with your IOS. No scan bodies or healing collars should be seated on the MUAs.
Step 4	Capture a 360° extraoral scan of the prosthesis with the IOS. Be sure to capture each scan analog and verify that there are no missed holes in the scan.
Step 5	Reseat. Capture the following IOS scans: Seated denture or prosthesis, capturing the surrounding tissue for landmarks Opposing Bite
	Creating the Master Cast - optional, but recommended: The doctor may choose to create a Master Cast of the loaded prosthesis. The benefit of creating the Master Cast is that the doctor can skip an additional appointment (see steps 9-16) and go straight to the Printed Try-In. To create a Master Cast, follow steps 6-7. If you are not creating a Master Cast, go directly to step 8.
Step 6	Acquire a flask, denture cup, or any container that can hold casting stone. Mix and pour casting stone into the flask.
Step 7	Set the prosthesis down in the stone. Ensure it is filled to the length of the analogs. It is important to ensure that the intaglio of the prosthesis is sitting a little bit above, not touching, the stone. Let the stone set up and become completely hard.
Step 8	Send all records to ROE Dental Laboratory. If a Master Cast was created in steps 6-7, ROE will fabricate or provide in-office printing files for Printed Try-In. The Printed Try-In is a 3D-printed prototype of the final prosthesis. See page 58 for more details. If a Master Cast was NOT created in steps 6-7, follow steps 9-16.
	iJIG to Printed Try-In: Follow steps 9-16 if a Master Cast was NOT created in steps 6-7.
Step 9	ROE fabricates and ships the iJIG.
Step 10	Add tray adhesive to the tissue side of each section of the iJIG. Screw down each section using the clear, suckdown transfer holder. Ensure all sections are fully seated and passive, and not touching each other. Capture an x-ray to confirm. Adjust for passivity if needed.
Step 11	Lute all sections with acrylic resin (e.g. Stellar, GC Pattern Resin, etc.) and cure.
Step 12	Equilibrate. Check VDO for speech issues. Capture the following PVS impressions: Opposing Bite
Step 13	Take the following photos with the patient standing up: Full-face full-smile Full-face exaggerated smile Optional: Full-face profile smile
Step 14	Make marks on the iJIG where esthetic changes are to be made. Add composite to simulate esthetics and adjust.
Step 15	Flow medium or heavy body PVS between the iJIG and the tissue.
Step 16	Send all records to ROE Dental Laboratory. Next, ROE will fabricate or provide in-office printing files for the Printed Try-In. The Printed Try-In is a 3D-printed prototype of the final prosthesis. See page 58 for more details. If patient and doctor are comfortable with the iJIG as the final prototype, you may choose to skip the Printed Try-In and order the final zirconia.
