CAD/CAM Software: The Hidden Costs Labs Don't Think About
CAD/CAM software is one of the most significant recurring costs in a digital dental lab, but labs often evaluate it based on the initial license price alone. The total cost of ownership includes several layers that the sales process doesn't always surface prominently. Here's what to account for before committing to a platform.
Annual Maintenance and Support Fees
Most perpetual software licenses come with an initial maintenance period (often 1 year) included in the purchase price. After that, annual maintenance renewal is required to receive updates and technical support. For exocad and similar platforms, annual maintenance is typically a meaningful fraction of the initial license cost.
If you let maintenance lapse to save money, you lose update access — which means falling behind on new material libraries, new implant component libraries, and bug fixes. This is a real cost when a material you want to mill isn't in an outdated library.
Module Add-Ons
The base CAD/CAM platform does crown and bridge. Everything else is often an add-on:
- Implant planning (exoplan): Separate module, separate cost
- Implant abutment design module
- Denture CAD module
- Orthodontic module
- CAM/manufacturing module (sometimes bundled, sometimes separate)
- Premium implant component libraries — some brands charge for library access
A fully-featured exocad setup for a complete implant workflow can cost significantly more than the base DentalCAD license alone. Budget for the modules you'll actually need.
Training
CAD software has a learning curve. For a proficient technician with some digital background: 20–40 hours of training to reach production efficiency is realistic for basic crown and bridge. For complex workflows (implant planning, full-arch design), the training investment is larger.
Training has direct opportunity cost: time in training is not time producing billable work. If you're bringing on a new technician or transitioning from one platform to another, factor the productivity lag into the cost calculation. Vendor-provided training, online courses, and distributor support all have their place — but none of them are free.
Hardware Requirements
CAD software runs on workstations that need to meet minimum specifications — and "minimum" often means "barely acceptable." For comfortable performance with large files (full-arch cases, CBCT data in exoplan), you want above-minimum specs: dedicated graphics card with substantial VRAM, fast storage (NVMe SSD), and sufficient RAM.
A workstation purchased cheaply and underspecced for your CAD software produces daily productivity losses. A technician waiting for the software to render, process, or load files loses time that's not tracked as a software cost but absolutely is one.
Migration Costs
Switching CAD platforms isn't free. When you switch from one platform to another, you lose:
- Accumulated custom design libraries (restoration templates, patient files in platform-specific formats)
- Technician proficiency (retraining period = productivity hit)
- Potentially, machine compatibility if the new software doesn't support your mill
Platform stickiness is real and intentional from the software vendor's perspective. Switching costs are one reason labs stay on platforms longer than the economics might otherwise justify.
Dongle and License Management
Many dental CAD platforms still use hardware dongles for license enforcement. Dongles are failure points — a damaged or lost dongle requires replacement, which costs time and money. Some platforms are moving to software-based licensing, but hardware-locked licenses are still common. Factor in the downtime and replacement cost risk of dongle-dependent systems.
The True Cost Calculation
A complete multi-year cost model for CAD/CAM software should include: initial license + required modules + first-year maintenance (usually bundled) + annual maintenance renewals + training + hardware + expected migration costs at end-of-life of the platform. This figure, divided by the number of designs produced over that period, gives you the real cost per design from software — which you can then compare against alternatives and against Flex (pay-per-use) options.
