Allen Milling Technologies – FDA 483, Jun 25, 2026

ALIEN MILLING TECHNOLOGIES, a manufacturer of dental aligners and custom dental abutments in Glendora, CA, was cited for significant deficiencies across its quality management system. The inspection revealed inadequate management reviews, undeveloped product realization processes, insufficient supplier controls, unvalidated manufacturing processes, and failures in nonconforming product control, corrective actions, and document control. These issues indicate a systemic lack of adherence to regulatory requirements and the firm's own procedures.
