Homeopathic Symphytum officinale increases removal torque and radiographic bone density around titanium implants in rats.
BACKGROUND
This study evaluated the effect of Symphytum officinale in homeopathic potency (6cH), on the removal torque and radiographic bone density around titanium implants, inserted in rats tibiae.


METHODS
Implants were placed in male rat tibiae, and the animals randomized to two groups (Control and S. officinale 6cH treated), which were evaluated at 7, 14, 28 and 56 days post-implantation. 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.
