Abstract EN
Purpose.
Friction-style and spring-style torque wrenches are used to tighten implant abutments and prosthetic screws.
The mechanical stability of these torque wrenches is crucial for the implant–abutment connection.
The purposes of this study were to assess the performance of five brands (Straumann, Zimmer, Implant KA, Bredent, and Biohorizons) of wrench and to evaluate possible changes in applied torque values of aged wrenches.
Materials and Methods.
Five new and aged wrenches that had been used approximately 250 times in a 1-year period were tested.
The torque applied by friction- and spring-style wrenches was measured with a specially designed strain gauge indicator.
Descriptive statistics, the one-sample t-test, and the independent-samples t-test were used to analyze values obtained from all torque wrenches.
Results.
The accuracy of new and aged torque devices of all brands except Bredent differed significantly from the target values, but the mean values for aged and new wrenches did not differ significantly from each other (p>0.05).
Values for the spring- and friction-type torque wrenches deviated from the target values by 11.6% and 10.2%, respectively.
Conclusion.
The accuracy of aged torque wrenches is adequate for prosthetic screw tightening, but that of new torque wrenches is unsatisfactory and must be examined carefully before delivery.
