In the treatment of maxillofacial fractures, it is important to apply the right amount of torque to osteosynthesis screws. A reference torque interval for the frequently used 1.5 and 2.0 mm osteosynthesis screws by oral and maxillofacial surgeons (OMF-surgeons) is not available. The aim of this study was to define a reference torque interval for osteosynthesis screws and compare the torque applied to 1.5 mm and 2.0 mm osteosynthesis screws by residents and OMF-surgeons. The calculated reference interval could help set up a preclinical training for clinicians. The central question that motivates this paper is: What is the aimed reference torque interval for an adequate and safe use of 1.5 mm and 2.0 mm ‘KLS Martin Maxdrive’ osteosynthesis screws? Five experienced OMF-surgeons and 20 residents, 5 of each 4 residency years, were included and asked to insert six 1.5 mm and six 2.0 mm screws each into a preclinical test model at two test moments, two weeks apart. Participants were blinded for the applied amount of torque. Torque values were averaged for both types of screws of each participant. The mean torque values were presented using descriptive statistics and then compared between the different groups. Intra-class correlation coefficients (ICC) were calculated per screw size per group (i.e., OMF-surgeons and residents) for reliability analyses. The mean torque value applied to 1.5 mm screws by residents was not significantly different from the mean torque value applied by OMF-surgeons (p = .38). The amount of torque applied to 2.0 mm screws by OMF-surgeons was significantly higher compared to the amount of torque applied by residents (p = .015). The mean torque value applied by residents to both the 1.5 mm as 2.0 mm screws did not significantly differ in between the residency years (p = .56 and p = .078 respectively). ICC of OMF-surgeons and residents were calculated of 1.5 mm (ICC was respectively .79, 95% CI [.00; .98] and .54, 95% CI [.00; .82]) and 2.0 mm screws (ICC was respectively .94, 95% CI [.15; 1.00] and .78, 95% CI [.46; .91]). A reference torque interval was not defined since the OMF-surgeons were not consistent in applying the torque. The OMF-surgeons applied a significant higher amount of torque to 2.0 mm screws than residents. Both experienced OMF-surgeons and residents were not consistent in applying the torque to both 1.5 mm as 2.0 mm osteosynthesis screws. A reference torque interval could not be defined.
