Adequate primary stability in the bone bed is essential for achieving osseointegration [Previous studies showed that conical implants have higher primary stability values than cylindrical implants [In the multiple linear regression considering the insertion torque as a dependent variable, statistical differences were detected for the implant macrogeometry (DC and MAE groups) and implant position (maxilla and mandible), corroborating results obtained in other clinical studies [Implant dimensions (diameter and length) can significantly influence initial stability values, especially in low-density bone [During the early period, predating the evaluations through RFA, the ISQ value varied in both groups. However, at baseline (immediately after the insertion of the implant), the overall mean of the ISQ was 61.1 ± 3.78 for the DC group and 61.9 ± 3.92 for the MAE group, without a statistical difference (Regarding the direction of measurements by RFA (buccolingual and mesiodistal), other studies that evaluated this variable as a possible important clinical parameter reported that no significant differences were found between ISQ values [Regarding the macrogeometry of the implants studied, the results showed that this is an important factor to be considered when accelerating the healing process, corroborating the pre-clinical studies recently published by our research group [Among the limitations of this study, we can mention that the results obtained are not automatically applied to implants with other macrogeometries since each implant design or dimension (length and diameter), as well as the osteotomy protocol used, must be evaluated separately. On the other hand, implants were placed in different patients and areas of the maxilla and mandible without following a single standard of quality and quantity for the residual bone tissue.
