Quick answer: the national average remake rate for lab-fabricated dental appliances is about 4%, with an acceptable range of roughly 1–7%, per Spear Education’s practice-management research. If your practice is remaking cases well above that range — or your lab can’t tell you its own number — the problem usually isn’t the last case. It’s the lab. Below: what a normal remake rate actually looks like, what drives it up, what a remake really costs, and the questions to ask before you decide it’s time to switch.
At OrthoDenco, we get some version of this question from every practice owner eventually: is this remake rate normal, or is it a sign we need a new lab? It usually comes up right after a bad week — a retainer that came back warped, an aligner that didn’t track, an appliance that needed a second impression the patient wasn’t happy about scheduling.
The honest answer is that some remakes are unavoidable. Case complexity varies, impressions aren’t perfect, and biology doesn’t always cooperate with a lab’s best work. The question that actually matters isn’t whether you had a remake. It’s whether your rate, tracked over time, sits inside a normal range — and whether your lab can even tell you what that rate is.
In this post, we’ll break down the industry benchmark for remake rates, what’s actually driving remakes up, what a remake costs a practice beyond the redo itself, and the specific questions to ask before you conclude the problem is your lab and not the case.
What Counts as a “Normal” Remake Rate
A remake rate only means something in context. One redone retainer in a slow month tells you nothing. A rate that’s trending up, or that you can’t get a straight answer about from your lab, tells you a lot.
Practice-management research from Spear Education puts the national average remake rate for lab cases at roughly 4%, with a normal range between 1% and 7% depending on case mix and appliance type. That’s the benchmark to measure against — not zero, and not whatever number your current lab happens to be running.
A common scenario: a practice notices three or four remade retainers in a month and assumes something changed on their end — a new assistant taking impressions, a run of complex cases. Sometimes that’s true. But when the pattern holds for two or three months running, the variable that changed usually wasn’t the practice. It was the lab’s own quality control.
At OrthoDenco, we treat our remake rate as a number we’re accountable for, not a number we hope doctors don’t ask about. Every case runs through in-house quality control before it ships — because a lab that doesn’t know its own remake rate can’t tell you whether your last bad case was an outlier or a pattern.
What’s Actually Driving the Number Up
When a remake rate climbs, it’s rarely one dramatic failure. It’s usually one of a small set of recurring, preventable issues.
The same research from Spear Education identifies the most common root causes: poor marginal fit, open contacts, occlusal issues, and — more than most practices expect — incomplete case information. The article cites that “eighty percent of dentists do not complete the information legally required on the prescription form,” which means a meaningful share of remakes trace back to a communication gap before the appliance is ever fabricated, not a manufacturing defect after the fact.
A common scenario: a lab receives a case with minimal notes on bite relationship or appliance preference, makes a reasonable assumption, and ships. The appliance is well made — but it’s built to the wrong assumption. That’s a remake that a phone call could have prevented, and it shows up in the numbers as a “lab quality” problem when it’s really a process gap on both ends.
At OrthoDenco, our production process is built to catch both kinds of failure — the fit-and-finish kind and the missing-information kind. Every appliance uses annealed flat braided wire with pre-production heat treatment and metal mesh pads for retention, and cases with retention concerns get a dual-layer IBT tray option rather than a one-size answer. When a case comes in incomplete, our technicians flag it and call — because catching the gap before production is faster and cheaper than remaking after.
The Real Cost of “Just a Remake”
It’s easy to treat a remake as a minor inconvenience — a redo, a delay, an apology to the patient. The financial reality is bigger than that.
Spear Education’s research anchors the cost to practice overhead: at an average of roughly $375 per hour, a 20-minute chairside adjustment represents over $100 in forgone revenue, and 30 minutes recalling a patient for a new impression runs closer to $190. A full remake — the original appointment plus a redo visit — can add up to over $1,000 a year per case type if the pattern repeats. Chair time lost to any avoidable cause compounds the same way: it’s not one appointment, it’s the schedule around it.
A common scenario: a practice loses a chair slot to an unplanned remake appointment, has to bump a same-day patient to fit the redo in, and absorbs a scheduling ripple that lasts the rest of the week. None of that shows up on the lab’s invoice. All of it shows up on the practice’s bottom line.
At OrthoDenco, we track on-time delivery at 99.7% and give every client direct access to the technician who actually built their case — not a general support line — specifically because the cost of a remake is never just the appliance. It’s the appointment, the schedule, and the patient’s confidence in the practice.
“A remake rate is a report card on how a lab is run — not a report card on the doctor’s impression technique. If we can’t tell a practice our own number, we haven’t earned the right to ask them to trust us with the next case.”
— Rene Silva, Managing Partner, OrthoDenco
The Questions to Ask Before You Decide It’s a Switch-Lab Problem
Before you write off a bad week as bad luck — or write off your lab as the problem — get specific answers to these:
- What is your documented remake rate, and will you share the actual number?
- Where is manufacturing actually done — in-house, or outsourced and overseas?
- What quality checks happen before a case ships, not after it comes back?
- When a case does need to be remade, who owns it — a specific person, or a general queue?
- What’s your average turnaround time, and how does that change when a case has to be redone?
A lab with a healthy process will answer all five without hesitation. A lab that gets vague, defensive, or redirects to “industry standard” without a number is telling you something about how it’s run.
The Real Question Isn’t the Number — It’s the Pattern
One remake is a case. A rising rate, or a lab that won’t discuss its own number, is a pattern — and patterns are what you should be evaluating a vendor on, not isolated incidents. At OrthoDenco, we built our process around the belief that national-lab reach shouldn’t cost you local-lab accountability: every case is manufactured in-house, tracked from impression to delivery, and backed by a technician you can actually reach if something needs a second look. That’s how a remake rate stays a number worth sharing instead of one worth hiding.
If your practice is fielding more remakes than it used to — or you’ve never actually asked your lab for its number — it’s worth a conversation. Contact OrthoDenco to talk through your current rate, or explore our full range of orthodontic appliances and how our in-house process is built to keep remakes the exception, not the pattern.
Frequently Asked Questions
How many remakes is considered “normal” for an orthodontic lab?
Industry practice-management research puts the national average remake rate for lab-fabricated dental appliances at about 4%, with an acceptable range of roughly 1% to 7%, depending on case mix and appliance type. A rate inside that range, tracked consistently, is normal. A rate that’s climbing, unmeasured, or consistently above 7% is a lab problem, not a case-by-case problem.
What does a remade case actually cost a practice?
Beyond the cost of the redo itself, a remake burns chair time that would otherwise generate revenue. Practice-management research estimates roughly $375 per hour in average U.S. practice overhead, meaning a 20-minute chairside adjustment can represent over $100 in forgone revenue, and a full remake — original appointment plus a redo visit — can cost well over $1,000 a year if it happens repeatedly.
What causes most orthodontic appliance remakes?
The most common root causes are poor marginal fit, occlusal issues, and incomplete case information reaching the lab. Prescription completeness matters more than most practices assume: incomplete or unclear Rx information is a leading contributor to appliances that don’t fit as designed.
How do I evaluate a lab’s quality control process before switching?
Ask for their documented remake rate, where manufacturing actually happens (in-house versus outsourced or overseas), what quality checks happen before a case ships, and who owns a problem when a case comes back — a specific person, or a support queue. A lab that can’t answer those questions with specifics is telling you something.
