The EPO published patent application EP4384114A1 disclosing a deep learning system for generating intermediate orthodontic aligner stages. The method uses neural networks (G06N 20/00) to process 3D dental models and generate treatment progression stages between initial and target positions. Inventors include Zimmer, Olson, Stark, Raddatz, Cunliffe, and Somasundaram. The application designates 31 EPC contracting states including all EU member states (AL, AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LI, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR).

This is a patent publication rather than a regulatory change. Competitors developing AI-based orthodontic planning systems should review the claims to assess potential freedom-to-operate implications. The patent, if granted, would provide exclusivity in designated EPC territories. No compliance actions or deadlines apply to this document.
