Distalizer FAST BACK Leone

Fast Back is an appliance for . the distalization of upper molars, developed with the technical and clinical assistance of Dr. C. Lanteri and Mr. F. Francolini. The Fast Back appliance provides the distal moment of the molars using a pre-determined amount of pressure whilst helping to maintain a good anchorage control. 

The principle of the Fast Back distalization is based on the compression of a MEMORIA® coil spring, available either in 200g or 300g, which exerts a consistent and constant force on the molars. The spring can be re-activated each month through the activation of the screws. The tube, pre-welded to the molar band, enables the screw arm to slide smoothly with total control of the direction of distalization. 

The Fast Back Kit contains all the items needed for the construction of a bilateral Fast Back appliance.
