K925700 is an FDA 510(k) clearance for the ZEST ANCHOR ADVANCED GENERATION. Classified as Attachment, Precision, All (product code EGG), Class I - General Controls.

Submitted by Zest Anchors, Inc. (Escondido, US). The FDA issued a Cleared decision on April 7, 1994 after a review of 511 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Dental FDA review panel, regulated under 21 CFR 872.3165 - 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.
