EU opens antitrust probe into Align over Invisalign and scanner tying

The European Commission has decided to look closely at how you straighten teeth, or more precisely, at the machine a dentist uses to scan them.

Brussels has opened a formal antitrust investigation into Align Technology, the American company behind Invisalign, over suspicions that it illegally ties its iTero intra-oral scanners to its clear aligners across the European Economic Area.

The probe, prompted by a competitor’s complaint, will assess whether the practice breaks EU competition rules.

The mechanics of the allegation are straightforward, even if the dentistry is not. Align makes two things that matter here: the iTero scanner, a device that produces a digital 3D model of a patient’s mouth, and Invisalign, the transparent aligners that have become the dominant brand in clear orthodontics.

The Commission’s concern is that Align may be arranging its products so that using the scanner steers practitioners toward Invisalign, and away from rival aligner makers, in ways that foreclose competition.

Tying, in competition law, is the practice of making the sale or full functionality of one product conditional on another. I

t is only a problem when the company doing it is dominant in one of the markets, because then the tie can leverage strength in one product to smother competition in a second.

The Commission evidently believes Align is powerful enough in clear aligners, scanners, or both, for the question to be worth a formal investigation rather than a quiet word.

The case arrived the way many do, through a rival. The investigation was prompted by a complaint from a competitor, which is the usual route by which the Commission learns that a dominant firm may be squeezing the market around it.

Align faces a crowded and increasingly aggressive field in clear aligners, including challengers pushing lower-cost alternatives, and the company has been fighting on several fronts, including patent litigation and trade complaints against rivals.

For Brussels, the move fits a long and consistent pattern. The Commission has built much of its modern competition doctrine on tying and bundling cases, most famously against the largest technology platforms, where it has repeatedly ruled that a dominant company cannot use strength in one product to lock in another.

Applying that logic to dental scanners and aligners is a smaller stage, but the principle is identical to the one the Commission has enforced against far larger firms.

It also reflects the EU’s broader willingness to scrutinise the conduct of dominant American companies operating in its single market, a posture that has defined its relationship with US technology firms from Apple’s App Store to Meta’s ad-tech bundling.

Align is a medical-device company rather than a platform, but it has found itself subject to the same instinct: that a dominant position carries obligations the Commission is prepared to enforce.

An investigation is not a finding. Opening a formal probe means the Commission has decided the concerns merit a deep look, not that it has concluded Align broke the law, and these cases routinely run for years before they resolve into a fine, a settlement of behavioural commitments, or a decision to close with no action.

Align will have the opportunity to respond and to argue that its products are integrated for legitimate clinical reasons rather than to exclude rivals.

What the company cannot control is the timeline or the scrutiny. A formal EU antitrust investigation is a serious matter for any firm that depends on the European market, carrying the risk of substantial fines and forced changes to how it sells.

For now the question Brussels has chosen to ask is narrow and specific: whether the scanner and the aligner are tied too tightly together, and whether competition in European orthodontics is worse for it.
