K933639 is an FDA 510(k) clearance for the IMKB CONTRA-ANGLES. Classified as Handpiece, Contra- And Right-angle Attachment, Dental (product code EGS), Class I - General Controls.

Submitted by Micro-Mega (France, FR). The FDA issued a Cleared decision on September 21, 1994 after a review of 421 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.
