A PMMA or 3D-printed try-in seats beautifully. Everything looks ready. Then the final zirconia restoration arrives—and suddenly it rocks, binds, or refuses to seat completely.
What happened?
The problem may not be the final zirconia. It may be that the original try-in was flexible enough to compensate for an insertion-path or interface discrepancy that a rigid zirconia restoration cannot overcome.
Alien Milling created a better way to catch these problems before going final.
Introducing the Alien Full-Arch Zirconia Try-In
The new Alien Full-Arch Zirconia Try-In gives dental laboratories and clinicians the opportunity to evaluate a full-arch design in the same type of rigid material as the definitive restoration.
Manufactured from Alien HT Zirconia, it provides a rigid, one-to-one evaluation of the approved full-arch design—before investing in the final material, shade, and finishing.
Available for only $229 per arch, it is an affordable additional verification step for cases where predictable fit matters most.
Why PMMA and Printed Try-Ins Can Be Misleading
PMMA and 3D-printed materials are valuable during the provisional and diagnostic stages, but they naturally have more flexibility than zirconia.
That flexibility can allow a try-in to seat even when:
- Implant interfaces do not share an ideal path of insertion
- Interface angulations create binding
- The restoration is being slightly distorted during seating
- A scan or design discrepancy is present
- The arch is not completely passive
Because PMMA can flex, a fit problem may remain hidden until the definitive zirconia restoration is delivered.
Zirconia does not flex in the same way. If the interfaces are not compatible with the insertion path, the final restoration may rock or fail to seat completely.
The Alien Full-Arch Zirconia Try-In helps expose these concerns while there is still time to correct them.
Test What Actually Matters
The Zirconia Try-In is designed to help evaluate three critical areas before ordering the final restoration:
Passive Fit
Confirm that the arch seats completely and evaluate it for rocking, binding, or other signs of an insertion-path discrepancy.
Occlusion
Check the bite and identify adjustments that should be incorporated into the definitive restoration.
Phonetics
Evaluate speech and phonetics while confirming the overall tooth position and design.
This gives the laboratory and clinician an opportunity to verify the case in a rigid material before committing to the final zirconia, shade, characterization, and finishing.
Add Passive Fit Check Before You Submit
For another layer of confidence, run the design through the free Passive Fit Check App in the Alien Milling Arcade before submitting the order.
Passive Fit Check analyzes the implant interfaces and helps identify angulation and insertion-path concerns that could affect passive seating in a non-flexible restoration.
Using the app before production—followed by a physical Zirconia Try-In—creates a more complete verification workflow:
- Analyze the interfaces with Passive Fit Check.
- Submit the approved design for an Alien Zirconia Try-In.
- Verify fit, occlusion, phonetics, and tooth position.
- Adjust and rescan if necessary.
- Order the definitive restoration after the try-in is approved.
Important: This Is a Try-In, Not a Final Restoration
The Alien Full-Arch Zirconia Try-In is manufactured specifically for evaluation. It is not intended for final delivery or long-term clinical use.
To maintain an affordable price and fast turnaround, the try-in is produced using an expedited milling strategy.
As a result:
- Undercuts and fine finishing details are not addressed
- C-clamp milling is not performed
- Embrasures may have less definition and access than the final restoration
- The restoration is delivered in a sintered state
- Final glazing is not included
- Pink gingival finishing is not included
The Zirconia Try-In is intended to verify fit, occlusion, and phonetics. Its surface quality, embrasure definition, and finishing should not be considered representative of the definitive restoration.
Material and Shade Options
Every Alien Full-Arch Zirconia Try-In is manufactured from Alien HT Zirconia.
Standard shades may be ordered as desired, and white is also available for try-in purposes. Bleach shades are not available for this product.
Once the try-in is approved, the definitive restoration may be ordered in your preferred zirconia material, shade, and available finishing options.
What Happens If Adjustments Are Needed?
If adjustments are required, make them directly to the Zirconia Try-In and rescan the adjusted restoration.
A new Zirconia Try-In order is required whenever the design is modified. This allows the revised restoration to be verified again in rigid zirconia before proceeding to the final.
While this adds another verification step, it can help prevent a more expensive and time-consuming problem during final delivery.
Going from Try-In to Final Is Easy with Alien Rx V2
Once the Zirconia Try-In is satisfactory, ordering the definitive restoration is simple.
The new Alien Rx V2 includes a dedicated From Try-In section that displays your cases previously ordered with a Zirconia Try-In. Select the appropriate case to begin the final order using the approved design.
If Alien Milling designed the original Zirconia Try-In, you will not be charged another design fee when ordering the final restoration from that approved case.
A More Predictable Way to Go Final
A flexible prototype cannot always predict how a rigid full-arch restoration will behave.
The new Alien Full-Arch Zirconia Try-In gives laboratories and clinicians an opportunity to evaluate the restoration in zirconia before going final—helping identify potential fit concerns earlier, simplify final delivery, and reduce avoidable remakes.
Combine the Alien Full-Arch Zirconia Try-In with the free Passive Fit Check App for a smoother, more confident full-arch workflow from design verification through final delivery.
