K221851 is an FDA 510(k) clearance for the Lumina-PTFE Titanium. Classified as Barrier, Synthetic, Intraoral (product code NPK), Class II - Special Controls.

Submitted by Criteria Industria E Comercio DE Produtos Medicinais (Sao Carlos, BR). The FDA issued a Cleared decision on December 8, 2023 after a review of 529 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Dental FDA review panel, regulated under 21 CFR 872.3930 - the FDA dental device regulatory framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Dental submissions.
