Clear Aligner Turnaround Time: What They Don't Say

Every clear aligner manufacturer advertises a turnaround time, yet almost none explain what that figure actually measures.
Usually, the advertised clear aligner turnaround time represents the best-case scenario: a straightforward case, no revisions, and approval on the first pass. It is a real figure, but it does not tell you when a patient will actually receive their aligners. The gap between the two can reveal a great deal about how a manufacturer truly operates.
The number everyone quotes
The quoted turnaround time usually refers to production time only. The clock starts once a case file has received final approval, not when it is first submitted, and it assumes that nothing goes wrong along the way.
That's a fine number to have. It's a bad number to build a patient's expectations around.
What that number leaves out
A great deal happens between “case approved” and “aligners in hand” that never makes its way into the marketing copy. Aligners are produced in batches rather than on demand, so the point at which a case enters the production schedule matters. A case that does not pass quality control the first time may be held back, and a manufacturer worth working with should prefer this to shipping something that does not meet specification.
Refinements add time, too. A 2024 study covering 2,937 clear aligner treatments across 188 orthodontists found that around 70% of completed cases required at least one refinement. This is considerably higher than the 20% figure often mentioned casually across the industry.[1] Customs clearance and cross-border shipping can add further time when the factory is not local, making the quoted figure quickly look optimistic.
Where the real time actually goes
Complex cases take longer at every stage, not only in production. High-volume periods can slow down even manufacturers with a strong average performance. In arrangements where the brand’s clinical team remains involved in treatment planning, the back-and-forth involved in revisions can add several days that a simple turnaround-time figure was never designed to capture.
None of this makes the quoted number dishonest. It simply makes it incomplete.
Why clear aligner turnaround time matters for case acceptance
Practices typically give patients a timeline during the consultation, often based on the manufacturer’s advertised figure. If the manufacturer’s best-case turnaround time does not materialise, it is the practice that appears unreliable, not the manufacturer, which is one step removed from the patient.
That gap can affect trust, case acceptance, and, ultimately, whether a practice feels confident sending a manufacturer more volume.
What to ask a manufacturer before you sign
Ask for the average turnaround time across a recent quarter.
Ask how revisions are handled and whether they follow the original timeline or a separate one.
Ask what happens to turnaround time during the busiest period of the year.
Our global average turnaround time is five to seven days. It holds up across a recent quarter because production is spread across six factories on three continents, so a delay at one location does not hold up every case that follows.
Every facility carries FDA 510(k), ISO 13485, and MDR clearance, and there is no minimum order quantity. This means that a practice sending five cases a month receives the same disciplined approach as one sending five hundred.
Not every manufacturer will give you this level of detail. Whether they will is often a good indication of whether the number on their homepage means anything.
If turnaround time is the issue that concerns you most before choosing a manufacturer, ask us the same questions you would ask anyone else.
Ask us for our actual average. It is a question we are used to answering.
