IFU
Pronunciation: eye-eff-yoo
Also written as: IFU — Instructions for Use
Instructions for Use; the mandatory written documentation provided by an implant device manufacturer detailing safe and effective use of the product.
Full Definition
The Instructions for Use (IFU) is a regulatory-mandated document accompanying medical devices, including dental implants and their components, that specifies indications, contraindications, surgical protocols, torque values, sterilisation requirements, and storage conditions. Editors working on IFUs must apply a highly precise, imperative style and ensure compliance with applicable regulatory frameworks such as EU MDR 2017/745 or FDA 21 CFR Part 801. Technical editors must verify that torque specifications, drill sequences, and component compatibility tables in the IFU match the device's technical file. The IFU must never be paraphrased in ways that alter the clinical meaning. In manuscripts, the IFU is an important citeable reference for procedural parameters.
Usage
Usage note: Spell out in full on first use: 'Instructions for Use (IFU).' Plural remains IFUs.
