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) clearance11 records
Cleared as substantially equivalent to a predicate device. Not an FDA approval, and not a finding of safety or effectiveness.

Clearance records for Dentium 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 Dentium.
