The company behind Invisalign is embedding AI into every step of the orthodontic workflow. It's exciting — and it carries a real risk.

Align Technology's AI Orthodontic Revolution

I’m not an orthodontist. But I follow evidence-based innovation closely, and what Align Technology is doing right now deserves attention from anyone in the profession.

Align, the company behind Invisalign, has been embedding AI into every stage of the orthodontic workflow: automated tooth segmentation, predictive tooth-movement modelling, AI-driven digital treatment planning. In January 2024, they completed the acquisition of Cubicure, a Vienna-based 3D printing pioneer, for approximately 79 million euros (BusinessWire, 2024).

They now control the entire digital orthodontic chain, from initial scan through AI-powered treatment design to direct 3D printing of the final appliance. They’re producing over one million custom appliances per day (Orthodontic Products, 2024).

If the evidence shows it’s working, then why not? That’s my general stance on innovation.

What Cubicure brings

Cubicure’s patented Hot Lithography technology processes highly viscous resins to produce particularly tough and temperature-resistant polymers. In plainer terms: they can 3D print dental appliances that are stronger, more precise, and more durable than conventional methods allow (Additive Manufacturing Media, 2024).

Align’s long-term goal is to directly 3D print Invisalign clear aligners rather than 3D printing moulds and thermoforming over them. Direct printing means better fit, better consistency, and the ability to build in features that thermoforming can’t achieve.

Combined with AI-powered tooth segmentation (where software identifies individual teeth from a digital scan without manual input) and predictive movement modelling (where AI forecasts how teeth will respond to specific forces over time), you’re looking at a system that can design a complete orthodontic treatment plan with minimal human input.

They changed orthodontics once before

Before Invisalign, orthodontics meant brackets and wires for almost everyone. Align proved a different approach could work, and clear aligners are now a mainstream treatment modality used by tens of thousands of clinicians worldwide.

So when they integrate AI and advanced manufacturing into a seamless digital platform, I take it seriously. This isn’t a startup making bold promises. This is a company with a track record of actually transforming clinical practice.

The real risk: scope creep

This is the part that concerns me, and I don’t think enough people in the profession are talking about it.

AI-powered orthodontic tools make complex treatment planning look easy. When complex things look easy, people who aren’t trained to handle the complexity start doing them.

This is already happening with clear aligners. General dentists are increasingly offering orthodontic treatment that would historically have been managed by specialists. Some of that is entirely appropriate: mild crowding, minor alignment issues, well within a competent GDP’s scope with proper training.

But some of it is not appropriate. Complex malocclusions, cases involving skeletal discrepancies, patients needing extractions as part of their orthodontic plan. Research shows orthodontists are significantly more likely to employ auxiliary techniques (92 per cent use Class II elastics compared to just 37 per cent of general dentists) and far more experienced at managing complications in complex cases (PMC, 2024).

AI amplifies this problem. When the software generates a beautiful 3D treatment simulation showing perfectly aligned teeth, it’s tempting to think the hard work is done. But the simulation is not the treatment. The AI doesn’t know about the patient’s periodontal status, their compliance, their skeletal pattern, or the dozens of clinical variables an experienced orthodontist would factor in.

The GDC has been clear that dentists should only practise within their competence. But when AI makes everything look achievable, the line between competence and overconfidence becomes dangerously blurred (GDC, 2025).

A brilliant scalpel doesn’t make you a surgeon

I’m genuinely enthusiastic about what Align is building. The Cubicure acquisition is smart. The AI integration is impressive. It will make orthodontic treatment better, faster, and more predictable for patients treated by appropriately trained clinicians.

But AI tools should augment expertise, not replace it. A GDP with a weekend course in clear aligners and access to AI-powered planning software is not an orthodontist. The patients who end up with undertrained clinicians, emboldened by technology that makes everything look straightforward, are the ones who pay the price.

If you’re a GDP considering more orthodontic treatment because AI makes the planning easier, ask yourself honestly: do I have the training, experience, and clinical judgement to manage this case when things don’t go to plan? Because they won’t always go to plan. That’s when your patients need a clinician, not a technician following a computer’s instructions.
