Results : Does the manual insertion torque of smartpegs affect the outcome of implant stability quotients (ISQ) during resonance frequency analysis (RFA)?
In the test group, mesial and buccal ISQ values of 30 implants were recorded by four examiners (S1–S4) after hand tightening the smartpegs. The control group considered mesial and buccal ISQ values of 30 implants with mechanically inserted smartpegs. Only 147 values could be recorded because one transducer broke and thereafter no further values could be obtained for this implant. At torque values between 2 and 11 Ncm (mean 5.3, median 5), ISQ values between 71 and 85 could be registered. All values were correlated to a high primary stability (ISQ > 70). Table 1 displays the ranked variables ISQ mesial, ISQ buccal and torque computed. At torques between 2 and 11 Ncm (Fig. 3), the mean values of the ISQ values were mesially between 79.1 and 80.8 and buccally between 74.5 and 79.0 (Fig. 4). The buccally measured values were generally lower. A possible explanation for this finding could have been the existence of a thinner buccal bone wall of the utilized bovine ribs. A comparison of all measured values (n = 147) including the manual torque achieved by the four examiners and the mechanical torque achieved by the Meg-Torq device to seat a smartpeg displayed only a limited influence on the outcome of the resulting ISQ values (Table 2). Results for the calculation of the ratio between insertion torque and ISQ values were recorded and differences between the subjects were computationally eliminated. In this case, no statistically significant influence of the torque used to place a smartpeg transducer on the registered ISQ value could be demonstrated, neither for mesial (p = 0.343) nor for buccal (p = 0.890) ISQ values (Table 3).
