Evaluation of primary stability in modified implants: Analysis by resonance frequency and insertion torque

“…22 Regarding the insertion torque, we found that the Qs (16.19 N.cm) and (control) (18. There is a consensus in the literature that the greater the bone density at the surgical site, the greater the primary stability of the implant. 25,26 Therefore, the low values of insertion torque and ISQ values for the implants due to the low density of the bone blocks used in the present study are plausible. Conversely, the low bone density and absence of cortical bone in the present study allowed us to better evaluate the mechanical imbrication created by the new apex designs.…”

Design optimization under uncertainties of a mesoscale implant in biological tissues using a probabilistic learning algorithm

“…The biomechanical aspects play an important role in the techniques related to implants in bones and many research have been per-formed, in particular by using experimental investigations and by developing computational mechanical models for understanding the aging and the implants stability as a function of the geometric shape and of the dimensions of implants (see for instance [2,4,9,17,19,32,37] and also [44,49,58,60,71,78,92,95]). Design optimization of implants in bone at macroscale by using deterministic computational models has also received increased attention (see for instance [36,43,50,53,56,74]).…”
