Open vs Closed CAD/CAM System: Avoiding Vendor Lock-In in the Dental Lab

The single biggest decision in lab digitalisation is not the scanner brand — it is whether your files are yours. A closed system ties design, milling and materials to one vendor; an open system exports standard formats so you stay free to choose.

What "open" actually buys you

• File ownership: open scanners export STL/OBJ/PLY, so scans drop into any CAD software and any mill.
• Best-of-breed mixing: pair one scanner with a different 3D printer and a third-party mill.
• Material freedom: buy zirconia, PMMA or resin from any supplier instead of the locked catalogue.

Where closed systems still win

Closed ecosystems can be faster to learn and offer single-vendor support — useful for a one-chair clinic that never wants to touch a settings menu. The trade-off is per-case margin and the inability to switch a weak link without replacing the whole chain.

Questions to ask before you buy

A low-risk path

Start open: an open intraoral or lab scanner that exports standard formats, feeding your existing CAD and any zirconia mill or open 405 nm printer. You keep every option open as the lab grows.
