The PRIME MIR KIT features all models plus the MIR HANDLE. The MIR allows a balanced orthodontic treatment, often without extractions and without promoting dental protrusion while the professional seeks the alignment of the teeth. With the MIR arches sequence, the professional has a series of abrasive strips, each calibrated to provide small polishing in the lateral regions, creating different spaces to align them without causing excessive projection of the teeth.
