Why labs outsource CAD design
Outsourcing the digital design phase lets a laboratory or clinic handle more cases without hiring additional in-house technicians. Instead of turning work away during busy periods, you send the scan files to a remote designer and receive production-ready files back — often overnight.
It also gives smaller labs access to design expertise across a wider range of indications than a single technician may cover: crowns and bridges, removable partial dentures, surgical guides, aligners, implant bars and full-arch work.
What you need to send
A remote design workflow starts with clean input data. The better the scan and the clearer the instructions, the better the first-pass design. In most cases you will need:
- STL or PLY scans of the preparation, opposing arch and bite registration
- The case prescription: indication, material, shade and any specific requirements
- For implant cases: the implant system, platform and scanbody library used
- Photos or a shade tab reference where aesthetics matter
What a good design partner checks before delivery
A reliable CAD design service does more than produce a shape. Before files are delivered, each design should be reviewed for the details that determine whether the restoration fits and functions:
- Margin line integrity and emergence profile
- Occlusal contacts and dynamic movement against the antagonist
- Proximal contacts and connector dimensions for bridges
- Minimum material thickness for the chosen material
- Correct implant library components and screw channel position
Turnaround and revisions
Routine single-unit work is typically designed overnight when files arrive by end of day. More complex cases — full arches, implant bars, combination cases — take longer and should be quoted per case. Revisions should be part of the service: small adjustments to contacts, occlusion or aesthetics are a normal part of a digital workflow, not an extra.
Keeping control of production
Outsourcing design does not mean giving up control. You receive open, production-ready files (usually STL) that run in your existing milling or printing setup, in the material you choose. The clinical and manufacturing decisions stay with you — the remote designer simply handles the digital phase.
If you want to try the workflow, the simplest start is a single crown case: send the scan files and prescription, review the design, and judge the fit at production.
