Skeletal open bite has been recognized as the most difficult malocclusion to correct, because of the high frequency of relapse.
Vertical control in clinical orthodontics is limited and requires excellent patient cooperation. Mini-implants and mini-plates have
served as anchors to support difficult orthodontics movements. The treatment of non severe open bite malocclusion using skeletal
anchorage is possible, by intruding posterior teeth using light elastic forces, then a desired anticlockwise mandibular autorotation
is obtained. The mean intrusion movement is 2-3 mm per side. It is described a mean relapse of 20-30% after one year posttreatment,
so is necessary overcorrect the molar intrusion to obtain the desired effect.
