Implant Torque Wrench
A calibrated instrument used to apply a precise and measurable rotational force when seating or tightening implant components.
Full Definition
The implant torque wrench is a controlled-force instrument essential in dental implantology for applying manufacturer-specified torque values — commonly expressed in Newton-centimetres (Ncm) — to abutment screws, healing abutments, and implant fixtures. Editors preparing device instructions for use (IFUs), surgical protocols, or regulatory submissions must verify that torque values are cited with correct units and match the referenced device specifications. The term should not be condensed to 'torque driver' without clinical context, as a torque driver may not be calibrated to the same precision. Variations include manual ratchet wrenches and electronic torque control devices, and authors should specify which type was used in methods sections.
Usage
Usage note: Always include the torque value in Ncm alongside any mention of this instrument in clinical documentation.
In Context
- "The abutment screw was tightened to 35 Ncm using a calibrated implant torque wrench per the manufacturer's protocol." — Operative report
- "Authors must specify whether a manual or electronic implant torque wrench was used, as inter-instrument variability can affect reproducibility." — Methods section editorial guideline
