No dentist enjoys the call that starts with 'the crown doesn't fit.' Remakes are one of the quietest profit leaks in a dental practice — another appointment, another impression, another round of lab time, and a patient whose confidence in you took a small hit. The good news: the large majority of remakes are preventable, and most of the prevention happens before the case ever reaches the lab.
After thousands of cases on our bench, here are the five factors that move the needle most.
Remakes Are Expensive — For Everyone
Before the how, the why. A remake doesn't just cost the lab a redo; it costs you the chair time you can't bill, the patient goodwill you can't easily rebuild, and sometimes the case itself. This is part of the real cost of cheap crowns that bargain labs never put on the invoice — high-volume operations simply have higher remake rates baked in. Reducing remakes is one of the highest-ROI habits in restorative dentistry.
1. Capture a Clean, Readable Margin
The single most common cause of a poor-fitting crown is a margin we can't read. If the prep margin is buried in blood, saliva, or sulcular tissue — or if the impression captures a torn, dragged, or voided margin — even the best technician is guessing. Adequate retraction, hemostasis, and a moment to verify the margin is fully captured will eliminate a remarkable number of remakes.
2. Give Us Adequate Reduction
We can't create space that isn't there. Insufficient occlusal or axial reduction forces a choice between an under-contoured restoration and one that's high in occlusion. Following the reduction guidelines for your chosen material — and they differ between, say, lithium disilicate and zirconia — gives us room to deliver both strength and esthetics.
3. Communicate Shade in Detail
A single shade tab written on the prescription is the bare minimum, and it's the source of countless 'the color's off' remakes. A stump shade, a shade map noting incisal versus cervical, and a well-lit photograph with the shade tab in frame turn shade matching from a guess into a plan. As we've covered in depth, shade matching is as much art as science — but it starts with the information you send us.
4. Go Digital When You Can
Intraoral scanning removes whole categories of error: no tray distortion, no material pull, no shipping delays that let a PVS impression keep setting in transit. A clean digital scan also lets us flag a margin or reduction problem and call you before we mill — while the patient is still in the chair, not back for a second visit. Digital won't fix a bad prep, but it faithfully captures a good one.
5. Build a Relationship With Your Lab
The lowest remake rates we see come from dentists we actually know. When we know your name, your preferences, and how you like your margins, we catch the small stuff before it becomes a remake — and we'll pick up the phone when something looks off instead of milling it and hoping. A real lab partnership is a remake-prevention system in itself.
The Payoff
Tighten these five areas and most practices see remake rates fall fast — which means more productive chair time, healthier margins, and patients who trust the work. If you'd like a lab that treats your remake rate like its own problem to solve, let's talk. We'd rather help you get the case right the first time than be efficient at redoing it.
