Abstract

Determining the optimal loading schedule and measuring implant stability at different times are critical tasks. Numerous tools have been created to assess implant-bone stability as a sign of a well-treated implant. Thus, the objective of this cross-sectional study was to estimate the validity of the Osstell ISQ system for assessing implant stability. Osstell ISQ was used to complete implant stability registers for 60 implants across 18 patients. Two distinct SmartPegs (types I and II) were used to complete six measurements on each implant, or three measurements in a row with each transducer. In the 1st, 2nd, and 3rdmeasurements with SmartPegs I and II, the average ISQ was 71.36, 71.31, and 71.65, and 71.02, 71.58, and 71.76, respectively. For SmartPegs I and II, equivalent values or variations below three ISQ points were found in 46.3% and 58.6% of the cases, respectively. Both SmartPegs had an intraclass correlation coefficient of 0.96, and they also had repeatability and reproducibility of 0.96. An intra-class correlation coefficient analysis reveals nearly excellent repeatability and reproducibility for the RFA system Osstell ISQ. Measurements of Osstell ISQ have excellent repeatability.
