Every dental lab owner knows the sinking feeling of opening a case that just came back from a dentist. A crown that does not seat. A shade that is off. A bridge with an open margin. Whatever the reason, a remake means the same work done twice — and the lab absorbs the cost almost every time.

Remakes consume technician hours, push other cases back in the queue, strain dentist relationships, and erode your lab’s reputation. The industry average remake rate sits around 3 to 5 percent. Some labs run higher without realizing it because they do not track remakes systematically. Others have driven their rate below 2 percent through deliberate workflow changes — not by hiring more experienced technicians, but by building systems that catch problems before cases leave the lab.

The True Cost of a Remake

Most lab owners think of remake cost as a materials expense — a new zirconia disc, new porcelain. That is real, but it is the smallest part of the picture. The bigger costs are indirect: technician labor spent redoing work instead of producing new cases, disrupted scheduling as the remake jumps the queue and puts other orders at risk, shipping costs for the replacement, and relationship damage when dentists notice a pattern.

A single remake might cost $50 in materials but $200 or more when you factor in labor, shipping, and opportunity cost. A lab running at a 5 percent remake rate on 500 cases per month is absorbing roughly $5,000 in avoidable costs every month.

Common Causes of Remakes

Most remakes trace back to a surprisingly short list of root causes. Understanding these is the first step toward reducing them.

Poor Communication on Case Specs

This is the number one cause. The dentist sends a prescription that is incomplete, ambiguous, or hard to read. The lab makes assumptions to fill in the gaps. Those assumptions are wrong some percentage of the time.

Common examples include missing shade information, unclear prep margins on impressions, no indication of the desired material, or conflicting notes between the written prescription and the verbal request. The lab technician does their best, but “best guess” is not a reliable production strategy.

Shade Mismatches

Shade selection remains one of the most subjective steps in the entire process. A dentist selects a shade tab under one lighting condition. The technician fabricates under another. The patient checks the result under a third. Even when everyone is competent, the result can miss.

Digital shade devices help, but they are not universal. Many cases still arrive with a handwritten shade note and no photograph.

Impression and Model Issues

Bubbles, pulls, tears, and distortions in impressions lead to inaccurate models. If the lab does not catch these problems before fabrication begins, the resulting restoration will not fit. Digital impressions have improved this, but they bring their own challenges — incomplete scans, stitching errors, and bite registration problems.

Insufficient Quality Control

Many labs rely on the fabricating technician to also be the quality inspector. This is like asking a writer to proofread their own work. They will miss things because they already know what it is supposed to look like.

A crown can have a slightly open margin, a contact that is too tight or too light, or an occlusal surface that is off — and the person who made it may not catch it because their eyes have adjusted to the piece over hours of work.

Design Errors in CAD

As more labs move to digital workflows, CAD design errors have become a meaningful source of remakes. Incorrect connector sizes on bridges, walls that are too thin for the chosen material, or cement gaps that do not match the dentist’s preference all lead to clinical failures.

Workflow Changes That Reduce Remakes

The good news is that most of these causes are systemic, not random. That means you can address them with process changes rather than hoping individual technicians make fewer mistakes.

Standardize Your Intake Process

The intake step is where you have the most leverage. A structured intake process catches problems when they are cheapest to fix — before any fabrication begins.

Build a checklist for case intake that covers every piece of information your technicians need: shade, material, tooth numbers, special instructions, impression quality, and bite registration. If anything is missing or unclear, flag the case and contact the dentist before it enters production.

This feels slow at first. It is faster than doing the case twice.

A case tracking system that captures these details at intake makes it much easier to enforce consistency. When every case goes through the same structured entry process, gaps become obvious instead of hidden.

Separate QC From Fabrication

Your quality control step should be performed by someone other than the technician who fabricated the case. This does not require hiring a dedicated QC person — in a small lab, it can simply mean technicians inspect each other’s work.

The key is that the inspector approaches the case with fresh eyes. They check margins under magnification. They verify contacts with articulating paper. They compare the shade to the original prescription. They look at the case the way a dentist will look at it.

Build QC into your production workflow as a distinct stage, not something that happens informally. When QC is a defined step with its own checklist, it gets done consistently. When it is assumed to happen, it sometimes does not.

Photograph Everything

Before a case ships, photograph it from multiple angles under consistent lighting. This takes less than two minutes and gives you a reference if the dentist calls with a concern, creates a training library for reviewing what QC missed on cases that do come back, and builds trust when you proactively share images with dentists before their patient appointment.

Improve Shade Communication

Do not rely on a single shade note. Ask dentists to send photographs of the adjacent teeth with a shade tab in the frame. This gives your ceramist dramatically more information than “A2” written on a prescription. For high-value anterior cases, consider requesting multiple photographs under different lighting conditions. A small amount of extra effort upfront eliminates one of the most frustrating remake scenarios: a technically perfect crown in the wrong shade.

Track Remakes Systematically

You cannot reduce what you do not measure. Log every remake with the dentist, restoration type, reason, fabricating technician, and the stage where the problem should have been caught. After a few months, patterns will emerge — maybe 40 percent of your remakes come from three dentists who consistently send poor impressions, or remakes spike when cases skip QC due to rush orders. This data gives you specific, actionable things to address instead of a vague goal to “do better work.”

Use Design Review for CAD Cases

For digitally designed cases, build a review step between design completion and milling. A second set of eyes on the CAD design can catch connector sizing issues, thin walls, and cement gap settings before any material is consumed.

Many dental lab features in modern case management platforms allow you to track design review as a distinct workflow stage, making it easy to ensure every digital case gets reviewed before production begins.

Manage Rush Orders Carefully

Rush cases have higher remake rates. When you compress the timeline, every step gets a little less attention. Build rush-specific protocols that preserve critical quality steps even under time pressure, or be selective about which rush orders you accept. Accepting every rush order and simply asking technicians to work faster is a reliable way to increase your remake rate.

Building a Culture Around Quality

Process changes only work when the team understands why they matter. Share your remake data openly. When the rate drops, acknowledge it. When a pattern emerges, discuss it as a team and decide on a fix together. The labs with the lowest remake rates are not the ones with the most experienced technicians — they are the ones where quality is built into the process at every stage.

Start With One Change

If your lab does not currently have a structured approach to reducing remakes, start with one change. Add a QC checklist. Start logging remakes. Standardize your intake form. Pick the one thing that would have prevented your most recent remake and implement it this week.

Small, consistent improvements compound. A lab that reduces its remake rate by even one percentage point will save thousands of dollars over the course of a year — and will build a reputation that brings in more work.

If you are looking for a way to build structured QC steps and case tracking into your lab’s daily workflow, Prostiq is designed to do exactly that. You can try it free for 14 days and see how a defined workflow changes the way your team handles quality.
