Do labs charge more for complex cases?

For general dentists and prosthodontists, the practical question is not whether complex cases cost more but how the lab communicates that difference. A single-unit zirconia crown and a six-unit anterior bridge in feldspathic porcelain require completely different labor commitments. The six-unit case may involve multiple design iterations, custom staining sessions, and a longer furnace cycle. Billing surprises at delivery damage case profitability and the working relationship. Asking for a written fee schedule by case category before you submit is standard practice.

Full-arch implant cases (All-on-4, All-on-6, fixed zirconia hybrids) represent the steepest complexity tier. Engineering a passively fitting bar, designing the screw-access channels, and verifying occlusal vertical dimension all add hours that single-unit CAD/CAM work does not. Labs that quote flat rates on these cases either absorb the loss or cut corners on verification steps. Neither outcome helps the clinician. A transparent lab will break down the charge: design fee, milling, characterization, and any analog or abutment cost separately.

For small DSOs managing 10 to 30 offices, complexity pricing also compounds across volume. A predictable per-unit rate matrix by restoration type lets practice administrators forecast lab spend per location rather than reconcile invoices case by case. Dani Dental provides a documented fee schedule so account managers are not guessing month to month.
