Turnaround time is one of the most frequently cited criteria when dental practices and labs evaluate outsourcing partners — and one of the most misunderstood. A “5-day turnaround” from a lab in another country means something very different depending on when the clock starts, how the case is submitted, and whether shipping time is included.
How to Define Turnaround Time
When comparing labs, always clarify what “turnaround time” means to that lab:
- Lab production time: Time from case acceptance (complete, approved files) to completion in the lab. Does not include shipping.
- End-to-end turnaround: Time from case submission to the restoration arriving at your practice. Includes production + shipping time.
- Business days vs. calendar days: “5 days” from a lab that operates Monday–Friday excludes weekends. “5 business days” is typically 7 calendar days.
The most useful comparison metric is end-to-end turnaround from scan upload to delivery — because that’s what affects your patient scheduling.
Standard Turnaround Times by Restoration Type
| Restoration | Lab Production | Rush Production |
|---|---|---|
| Single zirconia crown (digital) | 3–5 business days | 1–2 business days |
| e.max crown | 4–6 business days | 2–3 business days |
| PFM crown | 5–7 business days | 3–4 business days |
| 3-unit bridge | 5–7 business days | 3–4 business days |
| Night guard / splint | 3–5 business days | 1–2 business days |
| Dental veneer (per unit) | 5–7 business days | 3–4 business days |
| Full-arch implant prosthesis | 10–15 business days | 7–10 business days |
| CAD design only (STL output) | Same day – 1 day | Same day |
Adding International Shipping Time
For offshore outsourcing of physical restorations, shipping time adds to the end-to-end turnaround:
| Destination | DHL Express. For cost benchmarks by restoration type, see our Dental Lab Outsourcing Cost Guide. For quality system requirements, read ISO 13485 for Dental Labs. DHL Express | FedEx International Priority |
|---|---|---|
| USA | 3–5 business days | 2–4 business days |
| United Kingdom | 2–4 business days | 2–3 business days |
| Australia | 3–5 business days | 3–4 business days |
A typical end-to-end turnaround for a zirconia crown from World Dental Lab to the USA: 3–5 days production + 3–4 days shipping = 6–9 business days total. Many clients schedule patient appointments 10–14 calendar days after the preparation appointment to allow comfortable buffer.
How to Reduce Your End-to-End Turnaround
1. Switch to Digital Submissions
The single largest turnaround improvement comes from switching from physical impressions to digital scan files. Physical impressions must be shipped to the lab before production starts — adding 3–7 days internationally. Digital files arrive in minutes. See our guide: Digital vs Physical Impressions: A Lab Perspective.
2. Submit Complete Cases First Time
Cases returned for missing files, inadequate scan quality, or unclear prescriptions add 1–3 days minimum. Submitting a complete, correct case from the start is the most reliable way to get the promised turnaround. See our STL file submission guide.
3. Use Rush Production Strategically
Reserve rush production for genuine emergencies — not routine cases. Overusing rush requests adds cost and can strain your lab relationship. Most labs prioritise long-term partners who plan ahead over high-frequency rush requestors.
4. Outsource CAD Design Separately
If you have local milling capability, outsourcing only the CAD design and receiving STL files back (same day for standard cases) can eliminate all shipping time from your workflow. See our CAD design service.
