Overview

DIO’s implants trade under the UF(II) and UV Active names, both grade-4 titanium fixtures with an SLA surface and an internal Morse-taper connection. The brand is most associated internationally with DIOnavi, a fully guided digital surgery and denture system, so "DIO" on a treatment plan often signals a digital workflow rather than a particular fixture. DIO Corporation is listed on the Korean KOSDAQ exchange.

Regulatory record

Read this before drawing conclusions. A clearance or certificate means a device may legally be sold in a market. It is not a finding that the implant performs well, and it is not a comparison against other implants. In particular, FDA "clearance" is not FDA "approval" — clearance means the FDA accepted the device as substantially equivalent to one already on the market. What these actually mean →

FDA 510(k) clearance2 records

Cleared as substantially equivalent to a predicate device. Not an FDA approval, and not a finding of safety or effectiveness.

Clearance records for DIO were retrieved from the issuing authority's own database, not from the manufacturer's marketing material. We attribute a clearance to a brand only when the filing holder belongs to that brand's corporate family — third-party clearances for compatible components are excluded, because they belong to the company that made the component, not to DIO.
