Torque, Screw Joints & Implant Success

Instrument aspiration is an acute, in-the-moment risk. Screw joint failure is a slower one — but it's a more common reason implant restorations run into trouble after placement, and it's directly tied to how torque is applied and verified.

In Tips for Successful Implant Screw Joints (Decisions in Dentistry, 2023), Dr. Chandur Wadhwani outlines practical considerations for achieving a stable, long-lasting screw joint — including the role that accurate, verified torque plays in preventing loosening, fracture, and the downstream complications that follow.

Torque wrenches are mechanical instruments, and like any mechanical instrument, their calibration can drift with use. A wrench that reads 35 N·cm but is actually delivering something else introduces exactly the kind of variability that undermines screw joint integrity — regardless of how carefully the clinical protocol is otherwise followed. This is the problem ImplantWise's ITVS Digital Mk1 and Newton Verifier are built to catch — confirming, independently, that the torque a wrench reports is the torque it actually delivers.

Key takeaway: Screw joint success starts with torque accuracy. Verifying wrench calibration is a straightforward way to remove one variable from a process where precision has a direct bearing on implant longevity.
