Alien™
Verification Jig for Full Arch Hybrid
Jig Workflow
Why Use a Jig?
A jig is used to verify the accuracy of your digital scan before moving forward with a full-arch restoration.
Intraoral scanners capture teeth extremely well. However, when scanning large edentulous spans—where scan bodies are surrounded only by soft tissue (gingiva)—the scanner may struggle to accurately “stitch” the data together. This can cause the scan bodies to appear slightly closer together or farther apart in the digital scan than they are clinically.
This type of error is known as a mis-stitched scan, and it can lead to misalignment in a full-arch restoration.
The purpose of a jig is to confirm that your scan data is accurate before proceeding—saving time, cost, and frustration later in the process.
How to Order a Jig
-
Place the multi-unit abutments (MUAs) in the patient.
-
Attach the scan bodies to the MUAs.
-
Take an intraoral scan with the scan bodies in place.
-
Submit an order for a Jig here by uploading the scan.
What Happens at Alien Milling
-
Alien Milling receives your scan.
-
A verification jig is digitally designed from your scan data.
-
The jig is precision-milled in titanium.
-
The completed jig is shipped back to your office.
Jig Workflow After Receipt
-
Place the jig intraorally on top of the MUAs.
-
Screw the jig down using a cross-pattern (criss-cross) sequence, tightening gradually.
-
Do not fully tighten one side before the others.
-
-
Ensure there is no rocking or resistance as the jig seats.
What You’re Checking
-
The jig should seat passively, without forcing, pulling, or pushing.
-
A passive fit confirms your original scan was stitched accurately.
If you feel resistance or the jig does not seat passively, this indicates the original scan was not accurately stitched. In this case:
-
A new scan will be required
-
A new jig should be ordered before proceeding
Why This Matters
The jig is a critical verification step in full-arch workflows. It ensures that your digital foundation is accurate so everything that follows—design, milling, and final restoration—is built on reliable, precise data.
Using a jig early can help prevent costly remakes and protect your full-arch case from avoidable errors.

QUESTIONS & ANSWERS
Ask a Question-
Can this be sectioned and luted together in traditional verificaiton jib style if it doesn't seat passively? If not do you make a traditional verification jig that can be sectioned and re-luted together?
It is milled from a titanium blank.
It will be harder to section, and am not sure about looting.
Since it was designed to verify the accuracy of 3D Scans, it was meant to do just that.
If you were to section and loot somehow, there is no physical model.
It would require a new scan and new jig if the original does not fit.
-
What material is the verification jig made out of?
Medical Grade Ti-5 Titanium

For the Verification Jig for Full Arch Hybrid, what happens if it does not fit ? What are the next steps and additional cost ?
Hello
If a Verification Jig does not fit, that ussually means the Models, or Scans are inaccurate.
New Models, or Scans need to be taken, and a new verification jig will need to be ordered. -
i have an intraoral scan (medit 500) with anyridge/megagen scan bodies... what is my next step? future restoration will be some type of alien 8 restoration
You will need the DESS Megagen Scan Bodies
We recommend ordering the Alien iBar HT instead, as the Alien 8 will soon be discontinued.
For Full Arch Hybrid, you will need to order Multi-Unit Abutments, and place an MUA Scan Body on top.
Thank you.
