K133390 is an FDA 510(k) clearance for the NDX DORSAL APPLIANCE. Classified as Device, Anti-snoring (product code LRK), Class II - Special Controls.
Submitted by Institute For Quality Resource Management (St. Louis, US). The FDA issued a Cleared decision on October 16, 2014 after a review of 345 days - an unusually long review period, suggesting complex equivalence evaluation.
This device falls under the Dental FDA review panel, regulated under 21 CFR 872.5570 - 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Dental review framework, consistent with the majority of Class II 510(k) submissions.
