Pre-release · Invite-only evaluation

Dental CAD,
made for the Mac.

MacCrown designs single crowns, inlays and onlays, and fixed bridges. It is written natively for macOS and Apple silicon, not ported, so it works like the rest of your Mac.

Features

Everything a fixed restoration needs.

Single crowns, inlays and onlays, and conventional, Maryland and cantilever bridges, in one native app.

Scans in, repaired

Open STL, PLY and OBJ files from any intraoral or lab scanner. Every scan passes a nine-step mesh repair before design begins, so defects don’t surface later.

Margins you control

Trace the finish line with magnetic, freehand and point tools, then check every point in cross-section. Every margin is yours to review and edit before design.

512-shape tooth library

Age-appropriate anatomy for every tooth position, adapted to the preparation, the neighboring teeth and the opposing arch.

Freeform sculpting

Nine brushes (add, remove, smooth, push–pull, flatten, knife, groove, inflate and pinch) with 100-step undo. The margin stays pinned while you sculpt.

Live heatmaps

Wall thickness, contacts and occlusion are painted on the surface as you work, measured against the limits for the material you chose.

Checks before export

Every design is checked for wall thickness, contacts, occlusion and convergence. An export either succeeds cleanly or fails visibly, never silently.

Lab-ready files

Watertight STL and 3MF, with a construction-info file that describes the restoration for your lab or mill.

Private by design

Cases and patient records stay on your Mac. No account, no cloud service, no analytics.

Automation

Drive a whole case from the command line.

The design workflow is also available as a headless command-line tool and a local MCP server with 144 tools. Agents such as Claude Code and Codex can take a case from scan import to export.

FAQ

Questions.

When can I get MacCrown?

MacCrown is in an invite-only evaluation with dental professionals. It will then be released on the Mac App Store and here at maccrown.org. To take part, email feedback@maccrown.org.

Does MacCrown make clinical decisions?

No. MacCrown is design-assistance software for dental professionals. It helps you build and check a design; you review and approve every margin and every restoration before anything is exported.

Which scanners does it work with?

Any intraoral or lab scanner that exports STL, PLY or OBJ. Every scan is repaired on import.

Does it run on Intel Macs?

No. MacCrown is built for Apple silicon only and needs macOS 27 or later. It does not run under Rosetta.

Where are my cases and patient records stored?

On your Mac. MacCrown needs no account, has no cloud service and contains no analytics. See the privacy policy.

Can I send designs to my lab or mill?

Yes. MacCrown exports watertight STL and 3MF files, with a construction-info file that describes the restoration.

Do I have to use the command line or an agent?

No. The command-line tool and MCP server are optional, for people who want to automate. Everything is available in the app.
