Dental lab turnaround times: what’s normal and how to plan seat appointments
Dental lab turnaround is quoted in in-lab working days, and it varies by lab and by product. Here is how to read a schedule and book the seat appointment.

There is no single normal turnaround for a dental lab. Each lab publishes its own schedule, by product, counted in working days inside the lab.
So the useful question is how to turn your lab’s schedule into a seat date that holds. That takes the lab’s days, the travel on both ends and a gap.
This guide covers how labs count, what stretches a case, and a way to work out the date for any case.
How labs count the days
Labs quote a turnaround time in “in-lab working days”. Three details decide what that means on a calendar.
- When the count starts. Some labs start the day a case arrives, and some the day after.
- What a working day is. Weekends are out. Check which holidays are too.
- What is left out. The trip to the lab and the trip back are not in the number.
There is often a cut-off time as well. A case that arrives after it counts as received the next working day.
A digital case skips the first trip. A scan sent on Monday morning can be in the lab that day, where an impression may arrive on Tuesday or Wednesday.
Questions to ask about any schedule
- Does the count start on the day a case arrives, or the day after?
- What is the cut-off time for a case to count as received today?
- Which holidays do you close for?
- Are scans and impressions quoted differently?
- Which days does your courier deliver to our address?
Ask for the answers in writing, and keep them where the front desk books appointments.
One published schedule, as an example
Schedules differ, so read your own lab’s. This one is here to show how they are written.
ADL Dental Laboratories, near Toronto, publishes the following. It counts from the day after a case is received.
| Work | In-lab working days |
|---|---|
| Zirconia, e.max or porcelain-fused-to-metal crown | 5 to 7 |
| Implant crown with abutment | 10 to 12 |
| Full denture, set-up or finish | 4 to 5 |
| Cast partial, frame try-in | 10 to 15 |
| Night guard, from a scan | 3 |
We read that page in October 2026. Treat it as one lab’s numbers, and no kind of standard.
Three things stand out all the same. Implant work takes about twice as long as a crown, removable work comes back in stages, and every figure is a range.
What stretches a case
A schedule describes a case with nothing in its way. Several things add days.
- An open question. Work stops while the lab waits for an answer from the practice.
- Impressions. A physical case needs a courier first, and a model before work begins.
- Parts. An implant component on back-order holds up everything behind it.
- Stages. A try-in sends the case out and back, and each leg has its own count.
- Work sent on. A lab that sends part of a case to a partner adds that partner’s days.
- Busy weeks. The weeks before a long holiday are busy at many labs.
The first item is the one a practice controls. A complete Rx, and a same-day answer to any question, keep the count running.
Work out the date for a case
Add four pieces together, in working days.
- The trip to the lab. None for a scan. One or two for a courier.
- The lab’s days. Use the top of its range, and check when the count starts.
- The trip back. Ask which days the courier delivers to you.
- Your gap. Two working days is a sensible start.
Take a zirconia crown at a lab that quotes 5 to 7 days, counted from the day after receipt.
A scan sent on Monday is received that day. Seven working days from Tuesday ends on the following Wednesday.
With a day for delivery, the case arrives on Thursday. Two more working days puts the earliest safe seat on the Monday after.
That is two weeks from the scan. A front desk that books “a week from today” out of habit will book too early.
A zirconia crown from a scan, at a lab that quotes 5 to 7 days
A timeline of the worked example. The scan is sent and received on a Monday. The lab starts counting on Tuesday, and day seven is the Wednesday of the next week. The crown is delivered on Thursday, and after a gap of two working days the earliest safe seat is the Monday after.
Monday
Scan sent
The lab receives it the same day.
Tuesday
The count starts
This lab counts from the day after receipt.
Wednesday, week 2
Day 7 in the lab
Plan on the top of the range.
Thursday, week 2
Delivery
One day for the trip back.
Monday, week 3
Earliest safe seat
After a gap of two working days.
The same crown from an impression
Now take an impression on a Tuesday, picked up that afternoon. The lab receives it on Wednesday and starts counting on Thursday.
Seven working days ends on the Friday of the following week. Delivery is the Monday after.
Add the two-day gap and the earliest safe seat is that Wednesday, fifteen days after the impression.
Tell the patient the date as a plan when you book it. “We will confirm two days before” sets the right expectation.
Book by the kind of case
One rule for every case is too long for some and too short for others.
| Kind of case | What to allow for |
|---|---|
| Single back crown from a scan | The lab’s range, delivery and your usual gap |
| Front teeth | A wider gap, since shade questions are likely |
| Implant crown | The longer schedule, and a check that parts are in stock |
| Dentures and partials | A date for each stage, booked one at a time |
| Night guards and simple appliances | The shortest schedule, and still a gap |
Book staged work one stage at a time. A finish date set before the try-in is a guess.
Review these rules twice a year, and whenever you change labs or couriers.
When you need it faster
A rush is a request, and the lab can say no. Ask before the case is sent, and before the patient is promised a date.
Ask what it costs and what it gives up. A rushed case has no spare day for a question or a second look.
Tell the lab why. A patient who flies out on Friday is a reason a lab can plan around, and “as soon as possible” gives it nothing to work with.
If you find yourself rushing the same kind of case often, the booking rule is the problem. Lengthen it.
Keep your own record
A lab’s schedule is its plan. Your own record shows how the plan goes for your cases.
For each case, note the day it was sent, the day the lab said, and the day it arrived. Our free case tracking sheet has columns for all three.
After a few months, compare by lab and by kind of work. Tighten the gap where dates hold, and widen it where they do not.
Look at the late ones one by one. A case held up by an unanswered question belongs in a different pile from one the lab simply ran over on.
Share what you find with the lab. How to give your dental lab feedback covers how to raise it well.
Knowing before the day
A date worked out with care can still move. What matters then is hearing about it while the seat appointment can still be moved.
Agree with the lab how it will tell you. One channel that someone reads every morning is enough.

In Tusko, Chair Time shows each seat appointment beside its case and flags a late one before the patient sits down.

How long does a dental lab take to make a crown?
It depends on the lab and the material. One Ontario lab’s published schedule gives 5 to 7 in-lab working days for a zirconia crown, counted from the day after the case arrives. Ask your own lab for its schedule in writing.
What does “in-lab working days” mean?
The working days a case spends inside the lab. It leaves out the time to get there and back, weekends and holidays. Labs differ on which day the count starts.
How much buffer should we add to the lab’s date?
Start with two working days between the day the case is due back and the seat appointment. Widen it for implant, front-tooth and multi-stage cases, and shorten it once a lab has shown its dates hold.
Can a lab rush a case?
Many labs will, for a fee, if you ask before you send it. A rush uses up the slack that absorbs a question or a delay, so keep it for the cases that need it.
