[Distalization of upper molars: a new approach (clinical research)].

The Authors want to verify the effects of a new system of distalization of upper molars based on an active force of a coil-spring with an anchorage divided between the system itself and the cooperation of the patient. They evaluated cephalograms and casts of the patients examined. The purpose was to analyze the quantity and the quality of the distal movement; in particular they wanted to evaluate if this movement was a bodily one. Different parameters have been analyzed carefully and the results confirm that the distal movement has been significant and above all that it has been a bodily movement.
