How to give your dental lab feedback that improves the next case

Feedback improves the next case when it has four qualities. It is specific, it comes soon after the seat, it is tied to one case, and it includes what went right.

Many labs hear from a practice only when something has failed. Everything in between is silence, and silence teaches a lab nothing.

This guide covers what to say, when to say it, and how to raise a problem without turning it into blame.

Four qualities of feedback a lab can use

A checklist of the four qualities of useful feedback to a dental lab: it is specific, it comes soon after the seat, it is tied to one case, and it includes what went right.

• SpecificWhat you saw, in plain, physical terms
• SoonSent the day of the seat, while the details are fresh
• Tied to one caseThe patient and the tooth, in FDI notation
• Includes what went rightIt tells the lab what to keep doing

Why a lab rarely hears how a case went

Once a case ships, the lab’s view of it ends. It does not see the seat.

It does not know that the contacts were perfect, or that the bite needed ten minutes with a bur. Both look the same from the bench: no call came.

So a lab that hears nothing assumes all is well. A small habit that costs you time on every crown can go on for years.

The technician moves on to the next pan, and whatever this case could have taught is never written down.

The fix is cheap. The person who made the case needs one line about how it went.

What useful feedback contains

Each note should answer five questions.

• Which case. The patient and the tooth, in FDI notation.
• What you saw. In plain, physical terms.
• How much it mattered. Seated as it came, needed a small adjustment, or could not be seated.
• A picture, where one helps. A photo of the shade or the contact area says more than a sentence.
• What you would like next time. If you know.

The difference between a vague note and a useful one is easy to see side by side.

The last row matters as much as the others. It tells the lab what to keep doing.

When to give it

Send it the day of the seat. The details are fresh, and the lab still remembers the case.

A short note written at the chair by the assistant beats a perfect one that never gets sent.

After a try-in, send it before the case goes back. That note is the lab’s instruction for the next stage.

Do not save it up. A list of complaints from the last two months cannot be checked against anything, and it reads as an ambush.

If you are about to ask for a remake, say what you saw first. The lab may spot a cause that changes what should be remade.

A two-minute routine after every seat

Make feedback part of closing out the appointment. The assistant can record it while the dentist finishes.

Tick one box in each row, and add a line where a box in the last two columns is ticked.

Send it to the lab on the case, or in whatever channel you have agreed. The whole thing takes less time than writing up the chart.

After a month you will have a record of your own. It shows which kinds of case seat cleanly and which need work.

Say what went right

Praise is information. A technician who changed how they shape a contact wants to know if it helped.

Be as specific with praise as with problems. “The last three crowns needed no adjustment at all” tells the lab its change worked.

It also changes the tone of everything else. A lab that hears both sides takes the next criticism as part of a fair picture.

How to raise a problem

Start from the record, and from a question.

1. Describe what happened at the chair. Stick to what you saw and did.
2. Look at the Rx and the scan together. What was asked for, and what the lab had to work from.
3. Ask what the lab sees. A technician may notice something in the scan that was invisible at the chair.
4. Name the cause only when you both can. It may sit with the scan, the Rx, the design or the bench.
5. Agree on one change each. A fix on both sides lasts longer than an apology from one.

Keep the patient out of the middle. They need a good result and a new date, and nothing about whose fault it was.

A problem often has more than one cause. A margin that was hard to read on the scan, and a lab that did not ask about it, is one problem with two halves.

A message you can adapt

Keep it short enough to write between patients.

“Crown on tooth 36, seated today. The mesial contact was open, and floss passed freely. Photo attached. Could you check the contact strength in the design?”

It names the case, says what was seen and asks one question. Nothing in it assigns blame.

A written policy helps here. How to write a dental lab remake policy explains what a fair one covers.

Turn repeated notes into preferences

If you write the same note three times, treat it as a preference and put it on file.

“Lighter contacts on back teeth” or “leave the bite slightly out of contact” can be set once. Ask the lab to add it to your profile.

Then check it took. The next few cases should arrive the way you asked, and you should say so when they do.

A new dentist in the practice needs their own set. Preferences belong to the person holding the handpiece.

Ask for feedback in return

The lab has notes on you as well, and it is worth asking for them.

Once a quarter, put four questions to your lab.

• Which details do you most often have to ask us for?
• How are our scans, and where could they be better?
• Do our dates give you enough time?
• What do your easiest practices do that we do not?

The answers are worth acting on. A practice that sends a complete Rx and a clean scan gets the lab’s best work back.

Our dental lab prescription checklist covers the first of those questions.

Keep feedback with the case

Feedback sent by text or said on the phone is gone the next day. The technician who needs it may never hear it.

Write it where the case lives, so the Rx, the scans and the outcome are read together. A new technician can then read what the last one learned.

Tusko keeps every message on the case that the practice and the lab both open. A note about how a crown seated sits beside the Rx it came from.
