How should a DSO evaluate a dental lab partner?

Multi-practice groups in the 10-30 office range hit a specific operational problem: lab quality varies by location because each office inherited a different vendor relationship. One office ships to a national mill, another to a regional lab, a third to whoever the associate preferred in residency. The result is inconsistent fit, inconsistent shade, and no single vendor accountable when a case comes back wrong. Consolidating to one lab partner eliminates that fragmentation, but only if the lab can actually document its performance rather than promise it.

The metrics that matter most for a DSO evaluation are turnaround time by category (crown and bridge versus implant versus removable), remake rate tracked over a rolling 90-day window, and responsiveness when something goes sideways. A lab that routes support through a general inbox and responds in 48 hours creates chair-time losses that compound across 15 locations fast. The standard worth holding is: technician or case manager reachable same business day, turnaround SLA in writing, and a defined escalation path when a case misses.

Pricing transparency is the third filter most DSOs underweight. Per-unit pricing should be stable enough to build into a per-procedure cost model. If a lab's pricing sheet requires a phone call to interpret, or if discounts appear and disappear based on volume thresholds that reset quarterly, that is an operations problem, not a savings opportunity. Ask for a flat rate card, a sample invoice, and a 12-month remake log before signing any agreement.
