RESUMO
The optimal parameters of exposure to low-frequency magnetic field were chosen in experiments with 132 rats, using a simplex method of the extreme exposure. These parameters are as follows: 22 mT induction, length of exposure 20 min, pulse regimen. Exposure in such conditions provides the most effective influence of magnetic field on the reparative osteogenesis and mineralization processes and on the subsequent organic restructuring of the bone at the site of the mandibular standard defect.

An original method for the diagnosis of and monitoring the course of the mandibular fracture healing is suggested, making use of a graded indirect load of the chin. Clear-cut quantitative objective regularities in the time course of the pain sensitivity threshold values during the load have been detected, depending on the fragment localization, dislocation, and methods for fragment fixation. The knowledge of these regularities helps assess the efficacy of treatment, the quality of the fragments fixation, and the scope of rehabilitation measures for patients with mandibular fractures.
