Purpose: The purpose of this study was to present the concept and effect of buried magnetic field, comparing results in osseous wound with and without graft.

Material and methods: A surgical bone cavity was produced on the rat femur, the cavity was filled whit bone graft or remained empty. Metal devices consisting of commercially pure martensitic stainless steel washers and titanium screws were employed. Two metallic washers, magnetized in the experimental group but not in the control group, were attached on the borders of the cavity.

Results: The results suggest that the utilisation of bone graft associating magnetism and osseous conduction provide stronger results in new bone formation.

Conclusions: The bone neoformation observed suggest that the osteoconductor condition of the graft may be more susceptible to buried magnetic field stimulation.

Conflict of interest: None declared.
