A universal torque wrench system

摘要

Dental implant manufacturers supply various forms of torque limiting devices for use with implant restorations. A clinician may use these instruments to ensure adequate torque delivery with appropriate precision. Throughout the early period of dental implant prosthetics, screw loosening was a major complication, but a later study found that while screw loosening remained a potential prosthetic complication, it was less common than the early studies suggested. Nevertheless, inadequate tightening with insufficient torque has been cited as a possible reason for screw loosening.
