A technique to validate the accuracy of a beam-type mechanical torque limiting device

Abstract

Tightening torques are often specified in implant dentistry, including for surgical procedures, testing implant stability, and attaching prosthetic components when screws are used. The mechanical torque limiting devices (MTLDs) commonly used are typically either a toggle-type or beam-type. The International Organization for Standardization (ISO) 6789 recommends MTLDs should be periodically tested to confirm the validity of their readings, and, where necessary, recalibrated if possible or replaced. The verification of the toggle-type MLTD has been previously published. This article describes a straightforward, in-office technique to verify a beam-type MTLD.
