In some cases at the end of bracket treatment there is poor intercuspidation in the posterior region (caused by too little or incorrect torque) and straightening in the anterior region (caused by frequent tightening of elastic chains during diastema closure).
The retruded teeth can be realigned by using the BioFinisher® at the end of treatment. The BioFinisher® is a thermosensitive archwire that virtually fills the slot. It also has a very smooth surface due to its special plasma conditioning.
As the final archwire, the dimensions of the BioFinisher® ensure transfer of virtually all the preset values in each bracket.
