Lingual orthodontics in the new era treatment according to criteria for occlusion and aesthetics.

There has been remarkable progress in the field of orthodontics with the advent of CAD/CAM technology since the beginning of the 21st century. In lingual orthodontics, brackets designed and manufactured with a CAD/CAM system [1] are now available to produce more efficient tooth movement with reduced frictional resistance. The use of implant anchors for absolute anchorage has eliminated the need for excessive tipping of the molars with anchorage bends, which compromises periodontal health, as well as the need for application of heavy extraoral forces, thus providing more reasonable treatment options for both the patient and orthodontist.
