Radiographic bone density was measured at 6 points around the implant, using digital radiographic images, when implants were inserted and at sacrifice. Removal torque of the implants was also evaluated.Results - Both removal torque and radiographic bone density evaluation showed that S. officinale 6cH treatment enhanced bone formation around the micro-implants, mainly at 14 days. At 56 days, the radiographic bone density was higher in the treated group.Conclusions - We conclude that S. officinale 6cH enhances, principally at the early stages of osseointegration, bone formation around titanium implants in rats’ tibiae, based on radiographic and mechanical analysis.
