For more than a decade, Orthoproof has been a central digital production site for orthodontic practices and full-service dental labs across the Benelux. What started as a digital alternative to traditional plaster study models has become one of the region’s most advanced high-volume orthodontic production hubs.

Today, Orthoproof manages 800 digital dental models per day, alongside more than 1,200 conventional models. To keep pace with increasing demand, shorter turnaround times, and the industry-wide shift toward digital dentistry, the company needed a scalable, automated workflow.

A growing production challenge for high-volume dental labs

As intraoral scanning became the clinical standard—accelerated significantly after COVID-19—Orthoproof saw its digital volume rise sharply. But manual trimming, cleaning, orienting, and basing quickly became unsustainable.

“We simply couldn’t clean and base models manually anymore. The volumes were exploding.”

Orthoproof evaluated multiple AI vendors but none delivered the combination of speed, accuracy, and true production-grade reliability needed to support thousands of models per day.

Why Orthoproof chose Relu

After extensive evaluation, Orthoproof selected Relu for three strategic reasons. These criteria are now increasingly shared by dental labs seeking automation across the European Union or United States.

1. A more polished, more reliable output for dental labs

Relu’s AI consistently delivered clean, accurate, print-ready dental models, outperforming previous systems with fewer exceptions and a much lower defect rate.

“The dental models just look really sharp. You feel the AI system allows for good control of the end result.”

For high-volume orthodontic labs, consistency is non-negotiable — a single error can cascade across the entire process. Relu’s stability allowed Orthoproof to increase throughput without adding hard-to-find digital staff.

2. Best-in-class communication & true co-creation

A defining reason Orthoproof chose Relu was the collaboration experience with the engineering team.

“With Relu, the communication is fast and transparent. The team immediately understands our questions and what’s technically possible.”

Unlike other AI providers who often act as a black-box, Relu gave complete visibility into:

• Ongoing feature development
• Upcoming capabilities relevant to 3D printing dental labs
• Realistic implementation timelines
• Technical limitations and opportunities

This clarity created trust, speed, and shared ownership of the roadmap.

3. Relu Sync delivered in just two weeks

When Orthoproof highlighted the need for a local desktop syncing tool, Relu delivered their solution “Relu Sync” in just two weeks — a key requirement for large dental labs managing hundreds of daily files.

“That speed was the moment we knew: these are the people we want to work with.”

From evaluation to full Production: seamless scaling across the lab

Orthoproof executed a rigorous production-grade validation:

• 40–50 test cases per batch
• Direct comparison with legacy software
• Iterative improvements via screenshot, email, and WhatsApp
• Error-rate reduction until thresholds were surpassed

Once Relu consistently beat their previous solution, Orthoproof moved 100% of production to Relu the following month.

Today, all 800 daily digital dental models flow automatically through Relu Sync.

A “touchless” workflow: the future of digital orthodontic & dental lab production

Orthoproof now operates one of the region’s most automated digital production lines:

1. Raw intraoral scans enter Relu Sync automatically
2. Relu outputs clean, print-ready dental models
3. The CAM system automatically nests 14–15 models per printing job
4. Quality assurance of the final printed models before shipping.

“We print blind. We don’t even see the models before printing — only after they come out of the machine.”

This level of automation is the future for modern dental labs, enabling:

• Higher output
• Shorter lead times
• Greater process reliability
• Reduced hiring needs

Scaleable for the future

As Orthoproof becomes a centralized production hub for multiple dental lab locations in the Netherlands and Germany, the demand is multiplying.

Relu’s AWS-based elastic compute infrastructure ensures effortless scaling, whether volumes double, triple, or 10×.

“Whether we triple or 10x in the coming years, we trust that Relu’s systems will scale with us.”

Conclusion: reliability, speed, and a shared vision for dental lab automation

The Orthoproof × Relu partnership proves what’s possible when AI design accuracy, robust engineering, and production-grade reliability come together for dental labs.

Key benefits include:

• Cleaner, more predictable dental models
• Faster turnaround across orthodontic workflows
• Lower operational costs for digital dental labs
• A scalable, future-proof infrastructure supporting national and international growth

“Very simple: Relu keeps doing what they promise. Fast, reliable, and with a clear view of what’s coming next.”

Together, Orthoproof and Relu are setting a new benchmark for high-volume digital orthodontic and dental lab production in Europe and beyond.
