Premarket evidence — what FDA accepted
source quote (p.5)
“AudaxCeph Cephalogram Analysis Software is a software-only device intended for use by specialty dental professionals in the development of 2D dental treatment planning utilizing cephalogram landmarks.”
source quote (p.6)
“The technological principle for both the subject AudaxCeph Cephalogram Analysis Software and predicate CephX Cephalometric Analysis Software (K231396) is to utilize computer software to digitize landmark placement and measurement tasks. The accuracy study involved automatically-detected landmarks reviewed by orthodontists.”

Reported performance (0 observations)
FDA source did not state a quantitative performance metric — non-reporting is itself the signal.
Each value carries its own analysis unit and task — never compare or pool across devices. Source: 510(k) summary PDF.

Postmarket — what happened after clearance
Recall and MAUDE counts are product-code-level (reports aren't reliably attributable to one device); a recall is shown as device-attributed only when the recall record itself lists this clearance number. Signals are descriptive observables with sources — never a judgment that the device is unsafe or drifting. Snapshot 2026-07-08.
Reimbursement — how devices like this got paid
Not yet tracked — no payment pathway indexed for this clearance (the reimbursement corpus is a growing seed set).
Applicable FDA guidance — what the submission is measured against
FDA guidance documents and guiding principles applicable to 510(k) AI/ML devices in the Radiology panel. A curated reference index, not legal or regulatory advice — each item states its own status, and a draft is never binding.
