Planmeca CAD/CAM for Dental Labs: Equipment and Workflow Overview
Planmeca is a Finnish dental equipment manufacturer that has built one of the most comprehensive digital dentistry platforms in the industry—from imaging (CBCT, panoramic, intraoral) through chairside CAD/CAM (PlanScan) and into full milling systems (PlanMill). For dental labs, Planmeca's relevance lies primarily in its milling hardware and its open software approach, which makes it compatible with a wide range of CAD workflows. This guide covers the Planmeca CAD/CAM ecosystem from a lab technician and lab owner perspective.
The Planmeca CAD/CAM Product Line
PlanScan: The Chairside Scanner
The PlanScan intraoral scanner is Planmeca's chairside capture device. For dental labs, the PlanScan matters because it's the intake point for digital cases from Planmeca-equipped practices. Key characteristics:
- Scanning technology: structured white/blue light
- Output format: STL (open format)
- Integration: works with Planmeca Romexis software and exports to most lab CAD platforms
- Case transfer: cases can be transmitted via Planmeca Romexis Cloud to the lab
Labs receiving cases from PlanScan-equipped offices will receive STL files—a universally compatible format that can be imported into exocad, inLab CAD, 3Shape Dental System, or any other STL-compatible design platform without data conversion issues.
PlanCAD Easy: Chairside CAD Software
PlanCAD Easy is Planmeca's chairside design application, used primarily in single-visit crown workflows at the dental office. It is a simplified CAD environment optimized for fast single-unit case design, not for full lab case complexity. Labs working with Planmeca offices rarely interact with PlanCAD directly—cases are typically designed in more powerful lab CAD software after the scan data is received.
PlanMill Milling Units
The PlanMill line is where Planmeca has the most direct relevance for dental labs. The two primary lab-grade units are:
PlanMill 40 S
The PlanMill 40 S is a 4-axis dry milling unit primarily designed for chairside, single-visit crown production. It is compact and fast, optimized for milling e.max CAD, Vita Enamic, composite, and PMMA. For labs, the 40 S is relevant in in-office mill setups or for labs serving same-day workflows rather than high-volume overnight batching.
PlanMill 50 S
The PlanMill 50 S is a 5-axis unit capable of wet milling zirconia in addition to glass ceramics and composites. It bridges the gap between chairside and lab-scale production. It's relevant for small-to-medium labs or in-office labs that need zirconia capability without scaling to a full production-grade milling system.
| Feature | PlanMill 40 S | PlanMill 50 S |
|---|---|---|
| Axes | 4 | 5 |
| Milling type | Dry | Wet/dry |
| Zirconia milling | No | Yes |
| Materials | e.max, Enamic, PMMA, composite | All above + zirconia |
| Target user | In-office same-day | In-office or small lab |
| Disc size | 98 mm | 98 mm |
Planmeca's Open Ecosystem Approach
Unlike Sirona (which is built around its own closed Cerec/inLab ecosystem) or 3Shape (which integrates tightly with its own scanner and software), Planmeca takes a more open approach. The company has integrated its hardware platforms with third-party CAD software including exocad, and the PlanScan and PlanMill systems output and accept standard file formats.
This has practical implications:
- A lab using exocad as its primary CAD platform can design cases from PlanScan-originated scan data without workflow disruption
- PlanMill units can receive toolpaths generated by exocad's CAM module or third-party CAM software
- Labs are not locked into purchasing Planmeca scanners to use Planmeca mills
This openness is a meaningful advantage for labs that want hardware flexibility without committing to a single-vendor philosophy.
Working with Cases from Planmeca-Equipped Practices
If your referring practice uses a PlanScan, here's how the case typically flows to your lab:
- Dentist captures impressions with PlanScan
- Case is organized in Planmeca Romexis software
- STL files exported (upper arch, lower arch, bite registration)
- Files transmitted via Romexis Cloud, email, or file sharing to the lab
- Lab imports STL files into their design software of choice
- Lab designs, mills, finishes, and ships restoration
This flow is functionally identical to receiving STL files from any other scanner. Labs do not need Planmeca-specific software to receive or process Planmeca case data.
Milling Burs for PlanMill Units
Planmeca's PlanMill units use a standard 4 mm shank bur format, compatible with many third-party bur sets. Planmeca sells their own branded bur sets (recommended for warranty compliance), but many labs run compatible generic bur sets at significantly lower per-unit cost. If you operate a PlanMill unit:
- Verify bur shank diameter and taper against Planmeca's specifications
- For e.max CAD: use glass ceramic-specific burs (not zirconia burs)
- For zirconia (50 S): use zirconia milling burs rated for wet milling
- Track bur life carefully—the PlanMill's bur management system tracks wear, but accuracy depends on correct logging
Integrating Planmeca Data into Larger Lab Workflows
For high-volume labs receiving cases from multiple scanner types simultaneously, Planmeca data presents no integration challenges beyond any other STL-producing scanner. The key best practices:
- Establish a consistent file naming convention across all scanner types so cases don't get confused in your digital case management system
- Verify that the scan resolution and coverage (full arch vs. prep-area only) is appropriate for the case type before beginning design
- If the practice sends both digital scans and physical models, reconcile which dataset will be used for final design to avoid discrepancies
- Flag Planmeca cases in your case management system if any scanner-specific peculiarities (field of view, bite scan format) require technician awareness
Is a PlanMill the Right Investment for Your Lab?
The PlanMill line positions itself between chairside convenience and production-grade milling. It is best suited for:
- In-office labs where the dentist and lab share a space and same-day workflow is the core value proposition
- Small stand-alone labs doing modest volume (<500 units/month) who want a simple, reliable, well-supported system
- Labs already deeply integrated with Planmeca imaging and want end-to-end Planmeca workflow support
Higher-volume labs or labs with more complex fabrication needs (titanium milling, full-arch bars, multi-disc overnight runs) will likely find the production-grade competitors (Roland DWX-52DCi, Aidite AMD-500S Pro, VHF K5) better matched to their requirements.
