Signs You've Outgrown Your Aligner Manufacturer
Most brands don't leave a manufacturer on impulse. The decision builds up over months of small frictions — a case that shipped late, a refinement that shouldn't have been needed, a support email that went unanswered — until the cost of staying finally outweighs the discomfort of moving. Before you plan a migration, it's worth naming exactly what's driving it, because the reason shapes the strategy.
The common triggers cluster into a handful of patterns. Turnaround has slipped and your patients are waiting longer between scan and first tray. Refinement and remake rates are climbing, which quietly resets the treatment clock on case after case. Clinical support is thin — you're on your own when a case doesn't track. Pricing is opaque or margins are compressed. There's no portal or case visibility, so you chase status by email. Or the partner simply can't scale with your volume, or lacks the certifications you need for a new market you're expanding into.
If the problem is slow production or too many refinements, it's worth first confirming the issue is the manufacturer and not the inputs — our guides on what turnaround time actually measures and reducing refinements help separate a supplier problem from a records-and-approval problem. But once you've established the fault is on their side, the question shifts from whether to move to how to move without your patients feeling it.
- Turnaround keeps slipping and you can't get a straight answer on door-to-door timing.
- Refinements and remakes are rising without a change in your case mix.
- You have no visibility — no portal, no live case status, no doctor portal to track submissions.
- You're scaling or entering a new market and the current partner can't keep up or lacks the registrations.
The Real Risk Isn't Switching — It's Switching Badly
Changing suppliers for new cases is trivial: you send the next submission somewhere else. The risk lives entirely in the cases that are already in treatment — the patient on aligner 12 of 30, mid-way through a plan the old lab designed. A patient doesn't know or care which facility thermoforms their trays. What they experience is whether aligner 13 fits after aligner 12, and whether the next set arrives before the current one wears out.
That narrows the danger to two concrete failure modes, and both are avoidable with sequencing rather than luck.

| Failure Mode | What Goes Wrong | How to Prevent It |
|---|---|---|
| Supply gap | The patient finishes their last aligner before the next set is produced by the new lab. | Buffer active patients with enough trays to cover the full transition window before you cut over. |
| Fit / continuity mismatch | The new lab's trays don't continue the old plan — different staging, material, or a fresh scan that doesn't line up with the current stage. | Either finish the case on the original plan, or re-scan and re-plan the remaining movements as a clean continuation. |
Everything else in this guide exists to close those two gaps. Get the sequencing right and a migration is invisible to the patient; get it wrong and you'll spend the goodwill you built over the whole treatment in a single missed handoff.
Questions to Ask Before You Commit to a New Partner
A manufacturer that regularly onboards brands from other labs will answer these without hesitation. Vague or defensive answers are themselves a signal. Treat this as due diligence you do before giving notice to your current supplier, not after.
- Can you continue an in-progress case from another lab's plan?Ask directly whether they can take over mid-treatment cases, and exactly what they need to do it.
- What records do you require to take over a case?Typically the original or a fresh STL, the current aligner number, attachments already placed, and IPR already performed. Clarity here tells you how experienced they are at transfers.
- Will the material feel and behave like my current trays?A shift between multi-layer and single-layer sheets changes force delivery and fit — important for continuity on a transferred case.
- Do you hold the certifications for every market I sell in?Confirm FDA, CE / EU MDR, MHRA and TGA coverage matches your footprint, especially if you run multiple locations across regions.
- What are your turnaround and revision times to my door?Get design, production and transit times separately, plus how fast a requested setup change comes back.
- What visibility and clinical support do I get?A case-tracking portal and real planning support reduce the risk during the fragile transition window.
- Who owns my STL files and patient data?You need to keep and move your own records. Confirm ownership in writing before you rely on it.
- Is there a minimum order during ramp-up?A low or no minimum lets you pilot the partner on a few cases before committing your whole caseload.

Handling In-Flight Cases During the Transition
This is the heart of a clean migration. You have three viable ways to deal with cases that are already in treatment, and the right choice usually depends on how far along the case is and whether your old supplier is still usable.
Swipe to compare all columns →
| Approach | How It Works | Best When | Trade-off |
|---|---|---|---|
| Grandfather on the old lab | Let all current cases finish on their existing plans and trays. Route only new cases to the new partner. | The old supplier is still functional, and you have cases past the midpoint. | You run two suppliers in parallel for a while. |
| Transfer & re-plan | The new lab takes a fresh scan at the current stage and plans the remaining movements as a new continuation case. | The old lab is unusable — shut down, quality failure, or withholding records. | Requires a re-scan and a short re-planning cycle per patient. |
| Hybrid / phased | Grandfather complex and late-stage cases on the old lab; move only simple or early-stage cases to the new one. | A mixed caseload where some cases are nearly done and others just started. | More coordination — you're triaging case by case. |
The safe default for most brands is simple: grandfather anything past its midpoint on the existing plan, and move early-stage and new cases. Re-planning a case that's 80% finished introduces avoidable risk for almost no benefit. When you do transfer a case, treat the remaining movements like a fresh setup — which means reviewing it with the same rigour you'd apply to any new plan. Our guide on how to read and approve a 3D setup applies directly to every transferred case, and starting from clean STL records keeps the continuation accurate.
Moving STL Files, Treatment Plans & Case Histories
Your records are the asset that makes a clean switch possible — and the thing most brands forget to secure until it's too late. The single most important rule: export everything while your account with the old supplier is still active and in good standing. Once you give notice or a contract lapses, access to your own files can become slow, restricted, or gone.
Before you cancel anything, pull down and organise, per patient, the full record set the new lab will need to continue treatment cleanly.
- Original scans / STL files for every active patient, exported at full quality.
- Current treatment plans and 3D setups, including the full staging sequence.
- Progress per patient — the current aligner number and how many stages remain.
- Attachments placed and IPR performed to date, so the continuation matches the mouth.
- Prescriptions and case notes, plus your complete active-patient roster.
Confirm you actually own these files. Data and IP ownership varies by partnership model, and some agreements quietly keep your STLs and treatment plans on the manufacturer's side. If yours does, resolve it before you move — a migration is far harder when you're rebuilding records from scratch. A partner with a proper case-management portal makes both the export and the re-import dramatically cleaner, because everything lives in one organised place rather than scattered across email threads.
Keeping Patients on Track Through the Switch
The goal is continuity the patient never notices. Three things make the change invisible, and all of them are within your control.
Keep them in supply
Before you cut over, order enough aligners to cover every active patient through the transition window. This buffer is what prevents the supply gap — the single most common way a migration goes wrong. A patient who never runs out of trays never feels the switch.
Keep the brand and packaging consistent
If you run a white-label program, the trays, packaging and patient-facing brand stay identical regardless of which facility produces them. This is one of white-label's quiet advantages during a migration: the patient sees the same box from the same brand, start to finish.
Keep the clinical contact steady
Brief your front desk so nobody improvises an explanation, and keep the same clinician as the patient's point of contact. There's no need to announce a supplier change — frame everything as the continuation of care it is. The patient's relationship is with you, not your lab.
A Phased Migration Timeline
Sequenced properly, a switch is a controlled project rather than a leap. A typical migration runs four to twelve weeks depending on your active caseload. The order matters more than the speed — especially the rule that records come out before the old account is closed.
- 1. Audit and quantifyPull your baseline metrics and list every active case by current stage. This is your migration map and your scorecard for the new partner.
- 2. Vet and pilot the new partnerRun a handful of new cases end to end before committing. Grade real turnaround, tray fit, and support — not the sales pitch.
- 3. Export your recordsWhile the old account is still active, pull all STLs, treatment plans and your patient roster, organised per case.
- 4. Buffer active patientsOrder enough trays to carry every in-treatment patient through the transition window, closing any supply gap.
- 5. Cut over new casesRoute all new submissions to the new manufacturer once the pilot has proven itself.
- 6. Grandfather or transfer in-flight casesFinish late-stage cases on the old plan; re-scan and re-plan only the cases that genuinely need moving.
- 7. Close out the old supplierConfirm every record is exported and every buffered case is covered, settle billing, then cancel.
- 8. Monitor for 60–90 daysTrack fit, refinement rate and turnaround against your baseline to confirm the new partner is actually better.
If you're switching partly to support growth, plan the cutover alongside your capacity strategy — our guide on scaling case volume covers keeping turnaround stable as your numbers climb.

[email protected]Migration Mistakes That Cause Disruption
Nearly every disrupted switch traces back to one of a short list of avoidable errors. Knowing them in advance is most of the defence.
- Cancelling the old contract before exporting records. Get every STL and plan out first — access can vanish the moment you give notice.
- Moving late-stage cases needlessly. A case that's nearly finished should almost always stay on its original plan.
- Ignoring material differences. A change in sheet type can shift fit and feel; account for it on transferred cases.
- Skipping the pilot. Commit your whole caseload only after a few cases have proven the new partner end to end.
- No buffer supply. Without a tray buffer, any delay at the new lab becomes a patient running out mid-treatment.
- Assuming you own data you don't. Confirm STL and plan ownership in writing before you rely on moving them.
How Clear Moves Supports a Clean Switch
Onboarding brands from other manufacturers is a routine part of what we do, so the transition is built into our process rather than improvised. Send us the STL and the current stage of an in-flight case, and our team plans the remaining movements as a clean continuation — the same outsourced treatment-planning discipline we apply to every case, applied to transfers.
Because we run white-label production, your brand and packaging stay unchanged to the patient throughout the move. The doctor portal gives you live status on every case so nothing gets lost in the handoff, our certifications span the US, UK, EU and Australia for multi-market brands, and there's no minimum order — so you can pilot us on a few cases before committing your caseload. Whether you run a single practice or a multi-location DSO, we'll help you sequence the cutover so no patient ever runs out of trays.
Before you move a single case, map your active caseload by stage and secure your records. A switch done in the right order is invisible to your patients — and the fastest route to the turnaround, quality and support you left your old partner to find.
