Overview

DFI — the initials stand for Dual Fit Implant — is the middle option in Alpha-Bio’s internal hex range, less aggressive than the self-drilling Spiral and less parallel than ATID. Its double thread varies in depth along the body, which is the mechanism the manufacturer relies on for controlled insertion. Its length range stops at 13 mm, shorter than the rest of the family. Like the other Alpha-Bio implants it is made from Ti-6Al-4V ELI with the NanoTec surface.

The clearances below are held by Alpha-Bio Tec at brand level and cover its implant range, not Alpha-Bio Tec DFI specifically. We show them here because that is the level at which regulators actually issue them.

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) clearance1 record

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

Clearance records for Alpha-Bio Tec 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 Alpha-Bio Tec.
