K173570 is an FDA 510(k) clearance for the SD Abutment. Classified as Abutment, Implant, Dental, Endosseous within the NHA classification (a category for dental implant abutments and prosthetic components), Class II - Special Controls.
Submitted by Surgident Co., Ltd. (Seongnam-Si, KR). The FDA issued a Cleared decision on May 17, 2019 after a review of 543 days - an unusually long review period, suggesting complex equivalence evaluation.
This device falls under the Dental FDA review panel, regulated under 21 CFR 872.3630 - 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.
