Open bite + Aligners = Gold standard?
Clear aligner may have an advantage in treating open bite cases than traditional braces?
Open bite cases an be dental, skeletal or both.
Treatment can either include habit correction, extrude/retract anterior teeth, intrude posterior teeth or surgery
Advent of TAD’s in combination with aligners allow for intrusion of the molars that can result in a forward and upward movement from mandibular autorotation.
Molar intrusion by aligners is mainly due to the “bite-block effect” caused by two layers of aligner material between teeth.
Author utilised a combination of incisor extrusion (pure and relative), molar intrusion and consequent counterclockwise rotation of the jaw to help close the anterior open bite.
