ANSWERS

How should a DSO choose a dental lab partner?

A DSO between 10 and 30 offices should evaluate lab partners on four signals: documented turnaround SLA in business days, remake rate under 3%, single-invoice billing across all locations, and a named technician contact per case. Avoid labs that route through anonymous CAD pipelines or quote turnaround in weeks.

THE SHORT ANSWER

THE FULL PICTURE

Why it works this way

The four signals that matter

DSO procurement teams tend to optimize for price per unit, which is the wrong starting metric. Chair-time lost to remakes costs more than the unit price gap between a $89 crown and a $129 crown. The 2024 ADA Health Policy Institute survey of group practices found that 31% of multi-office groups cited lab quality inconsistency as their top operational complaint, ahead of pricing. Start with remake rate, turnaround SLA, billing structure, and technician access. Price is the fifth filter, not the first.

What turnaround time should a DSO expect from a lab partner?

Standard crown and bridge cases should ship within 5 to 7 business days from case receipt, quoted as an SLA not a range. Implant cases and full-arch hybrids run 10 to 21 business days depending on complexity. Removables sit at 10 to 14 business days. Any lab quoting in weeks rather than business days is hedging. For a DSO, the SLA matters more than the average, because chair scheduling depends on the worst-case day, not the median.

Should a DSO use one lab across all offices or multiple labs?

Single-lab partnership is the better operational model for DSOs between 10 and 30 offices. Quality consistency across locations, single-invoice billing, and one escalation path outweigh the redundancy argument. Multi-lab strategies create case-quality variance that clinicians and patients notice. The exception: specialty case routing (complex implant work, full-arch hybrids) may go to a specialized partner while the primary lab handles crown and bridge plus removables volume. Past 50 offices the math shifts toward multi-vendor.

What contract terms should a DSO negotiate with a lab?

Documented turnaround SLA with credit terms if missed. Remake policy that covers the lab's error at no charge with no question asked. Single-invoice consolidation with per-office line items for accounting. Direct technician contact for clinical questions. Quarterly business reviews with measured remake rate, on-time percentage, and case volume reporting. Avoid exclusivity clauses longer than 12 months and any pricing structure that locks in unit cost without volume-based step-downs as the DSO grows.
