Overview

DIO Corporation, listed on the Korean KOSDAQ exchange (039840), traces its origins to 1988 and was renamed from DSI Co., Ltd. in 2008. It is based in Busan’s Centum area. Its implant fixtures are the UF(II) and the newer UV Active, both grade-4 titanium with an SLA surface, but the company is best known internationally for DIOnavi, its fully guided digital surgery and denture workflow. That digital system, not the fixture itself, is often what a clinic is referring to when it markets "DIO".

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 →

Other2 records

Registered device establishment in South Korea. Registration records where a device is made or handled; it is not a clearance, an approval, or any assessment of the product.

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.
