Types of Dental Torque Wrenches - Manual mechanical torque wrench - Toggle torque wrenches - Beam wrenches with a dial indicator

Surgical Motor and Torque Wrenches - Surgical motor as an electronic controlled torque-limiting device - Motor or pneumatic torque wrenches used in high precision areas - Calibration before every use and in case of breakage or loss of calibration

Calibration of Dental Torque Wrenches - Deviations of 10% or higher from desired torque values - Regular recalibration with a torque tester restores required torque values - Calibration ensures accurate torque application - Regular calibration necessary for torque wrenches used in dental implants

Re-torquing of Fasteners - Settling effect causing a decrease of around 10% in torque over time - Re-torquing after 10 minutes reduces settling effect - Parts get more seated with re-torquing - Importance of re-torquing to ensure proper tightening

Wet and Dry Torque - Wet torques (bolts lubricated with saliva) have higher mean torque than dry torques - Lubrication with saliva affects torque values - Dry torques refer to unlubricated bolts - Wet torques provide higher torque values due to lubrication - Lubrication of bolts affects torque measurement
