Effect of static magnetic field on osseointegration of dental implant

Objective To observe the effect of static magnetic field on the osseointegration of dental implant.Methods The dental implants were placed into the femoral lateral condyle of rabbit and exposed to the static magnetic field with the intensity of 50 mT.At different time points after the implantation,the stability,bone combination ratio and extraction force of implant were detected.Result Within 8 weeks after the implantation,the implant stability,bone combination ratio and extraction force in the experimental group were higher than that in the control group(all P0.05).Conclusion The static magnetic field could promote the combination of dental implant with the bone and reduce the time that the dental implant reached the stable osseointegration.
