[The long-term observation of alveolar bone blood flow during tooth movement with the aid of skeletal scintigraphy in an animal model].
We observed in eleven dogs the blood flow in the alveolar bone during the tooth movement with the bone scintigraphy for one year. Additional we used for histological evaluation polychrome sequence marking and for improving of therapy electrostimulation. There is a correlation between tooth movement and blood flow. Four to six weeks after beginning tooth movement and blood circulation are reduced although the applied force was continuous all the time. This is an advice for stress interruption during treatment. Electrostimulation improves the conditions for tissue regeneration because the lifetime of osteoblasts is prolonged.
