K926154 is an FDA 510(k) clearance for the HANDPIECE MODELS: MS-350. Classified as Handpiece, Air-powered, Dental (product code EFB), Class I - General Controls.

Submitted by Dabi-Atlante America Corp. (Tampa, US). The FDA issued a Cleared decision on March 4, 1994 after a review of 452 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Dental FDA review panel, regulated under 21 CFR 872.4200 - 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.
