Pain-free and mobility-free orthodontics?

Pain-free and mobility-free orthodontics are not discussed often, although they obviously would be significant advances and very desirable practice-builders. These advantages have occasionally been reported in the orthodontic literature by different authors who used magnetic force fields for molar distalization, aiding tooth eruption, etc., and are presented here in Group I. Group II discusses several different possible mechanisms of action, including among others, an accelerated osteogenic rate and a sensory neuron action potential blockade. All the available evidence seems to confirm that pain-free and mobility-free orthodontics is a real phenomenon.
