Every lab struggles with a task that must be done quickly but is nearly impossible to bill for: the model. AI model generation software converts a finished crown case or intraoral scan into a print-ready working model—complete with dies, pins, and a base—eliminating the need for manual construction. The true ROI of AI isn't measured by how fast the machine runs, but by the minutes your technicians get back. Here is how to evaluate that impact before you touch a calculator.
Why let AI build the models at all?
Simply put, models are a pure cost center. Dentists pay for the crown; they assume the model is included. Yet that model must be sitting on the bench before anyone can seat a restoration. Ask any lab owner where time is wasted most, and the model room is almost always the answer.
The pattern is universal: a crown is designed, the case is closed, and someone reopens it to painstakingly build the model by hand, a few minutes at a time, dozens of times a day. Labs that outsource trade those wasted minutes for a per-case fee that eats directly into their margins. Either way, the model room remains the hardest seat to fill (what labs are doing about the technician shortage).
This makes models the perfect entry point for AI. Start where the stakes are lowest: models first, then crowns, then the rest of the catalog as trust builds. No critical design decisions are delegated, and you get those hours back from day one.
What goes into the cost of a model today?
Before you can measure the benefits of AI, you need to understand your current baseline. Don't just guess at the total cost; break down the components. Who builds your models? How many are produced on an average day? How many minutes does each one take—from opening the case file to exporting a print-ready file? Finally, what is the fully burdened hourly cost (including benefits) of that technician? Count the design and prep time only. Printing uses machine time, not technician time.
If you outsource, the math is simpler but the hidden costs are higher: factor in the per-model fee, the turnaround time lost while waiting for the file, and the time a technician spends performing quality control when it returns.
Where does the time go once AI builds the model?
This is where most ROI calculations go off track. People mistakenly compare a technician's time with the software's processing time. But the software's time isn't costing you labor.
With AI model generation, a technician only interacts with a batch of cases at three distinct touchpoints: uploading the files, confirming the settings, and downloading the print-ready results. Everything in between runs on its own in the background while your technician focuses on the billable crown work. However long a batch takes, no one is sitting there watching a progress bar. Count only those three manual touchpoints. The generation time is real, but it is not your time, and it shouldn't factor into your labor math.
How should you read the ROI?
Evaluate your ROI in three layers. First, calculate the total technician hours freed up over a year. Anchor your decision here, because this is the tangible relief you will feel on the lab floor. Second, translate those freed hours into dollar amounts based on your actual labor costs. Third, subtract the cost of the AI software subscription that fits your volume.
Freed hours only translate to real money if the lab redeploys them effectively—whether that means processing more cases with the same team, eliminating overtime, or moving a technician from the model room to highly profitable design work.
For labs that currently outsource, the primary benefit is immediate cash savings rather than time. The per-case fees disappear. What remains is the subscription and just a few minutes of internal labor per day to check and export files.
You don't have to abandon your existing CAD workflow to try it (AI dental design vs CAD/CAM). If you already design crowns in Dentscape, the model comes with them (AI crown design with a print-ready model, included).
What should you do next?
Run your own numbers. The Model Economics Calculator asks three simple questions about your current model production and breaks down the three ROI layers above. It also generates a PDF report detailing every assumption behind the math.
Once you have your numbers, book a demo and bring your report. While the calculator can show you the financial value of your saved time, it can't evaluate whether your specific cases, printers, and articulators are a perfect match for the software. A brief conversation will clarify that, so you know how well the system fits your lab before spending a dime.
