Dental lab costs: how much do they really impact your revenue?

The dental lab is typically the second biggest cost after staff, yet most practices track it as a single monthly total. That number hides which treatments are actually profitable.

A prosthetic case can look strong in revenue terms and still produce weak margin once lab incidence, chair time, remakes and adjustments are measured together. Lab cost belongs inside the treatment margin calculation, not outside it.

Average incidence on revenue

Lab costs vary widely by treatment mix. Prosthetics, implants and complex restorative work usually carry a much higher external cost than hygiene or conservative dentistry. Measuring the average is useful, but measuring incidence by treatment type is what protects margin.

Formula: lab cost incidence = lab cost / related treatment revenue x 100. If implant prosthetics generate EUR30,000 in revenue and lab invoices for those cases are EUR7,500, lab incidence is 25%. That may be acceptable or too high depending on chair time, clinician cost, remakes and target margin.

How to analyse lab invoices

Group invoices by case, clinician, treatment category and month. Then compare the lab cost with the revenue generated by the corresponding treatment. This avoids treating the lab as one generic expense and reveals where pricing or case planning needs attention.

The key is matching lab cost to the case that generated it. If invoices are reviewed only by supplier and month, the clinic cannot see which treatment type is consuming margin. A simple case code, patient reference or treatment category on each invoice can make the analysis much more useful.

Benchmarks by treatment type

A single benchmark for all lab work is misleading. Crowns, aligners, implant prosthetics and removable dentures have different cost structures. Each category should have its own target incidence and be reviewed against actual production.

For example, a crown, an aligner case and a full-arch prosthetic case should not be judged by the same percentage. The full-arch case may have higher lab cost but also higher revenue and strategic value. The question is whether the final contribution margin justifies the clinical time and risk.

How to negotiate

Negotiation should start from data: annual spend, number of cases, remake rates, delivery times and price by category. The goal is not only a lower price, but reliable quality, predictable turnaround and clear conditions that support the practice's profitability.

Remakes deserve special attention. A lower lab price is not useful if the practice loses chair time correcting work, rescheduling patients or absorbing complaints. Track remakes by lab, treatment type and clinician so negotiation includes quality and operational impact, not only the invoice price.

Case planning also affects lab cost. If the treatment plan changes after the lab work starts, or if records are incomplete, external costs can rise without appearing as a pricing problem. A short protocol for scans, impressions, photos and approval steps helps reduce hidden rework.

For larger cases, estimate lab incidence before presenting the final price. If the planned lab cost already consumes too much of the revenue, the clinic can adjust pricing, payment terms or clinical approach before the case is accepted. Waiting until the invoice arrives makes the margin problem harder to correct.

Use annual volume when negotiating, but keep the conversation by category. A lab may be competitive for crowns and weak for implant prosthetics, or reliable for simple work but slow on complex cases. Splitting spend by category makes it easier to decide where to consolidate, where to keep alternatives and where to renegotiate terms.

The finance view should include timing as well. Lab invoices often arrive before the patient has fully paid for the treatment. If payment plans are long and supplier terms are short, the clinic may have a cash issue even when the treatment margin is acceptable. That is why lab cost should be reviewed with collections, not only revenue.

To get started: group lab invoices by treatment, calculate incidence, track remakes, review delivery delays, compare price lists and connect lab cost with dental KPIs. EUSTAK helps by aggregating invoices and making lab incidence visible by month, so negotiation starts from facts instead of impressions.
