K151608 is an FDA 510(k) clearance for the 4plus6Line Abutment System. 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 Ot Medical GmbH (Bremen, DE). The FDA issued a Cleared decision on April 13, 2016 after a review of 303 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: 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.
