for screw connections in titanium dental implants
The dentist has the job of screw-fitting crowns to titanium dental implants. The torque needs to be monitored during implant screw-fitting. The torque typically lies in a range of 15 to 50 Ncm with a speed of 1500 to 2500 1/min.
The 8661 torque sensor was selected for the torque measurement. The test setup measures an efficiency factor by comparing the drive and drag, i.e. the torque and speed, to give a quality rating.
