Analisi degli effetti della terapia con distalizzazione molare

Both the extra- and intraoral appliances were efficient in achieving a Class I molar relationship. Use of the Kloehn headgear allowed the maxillary molars to be distalized without altering the flaring of maxillary incisors. Noncompliant intramaxillary appliances (Pendulum, First Class, Distal-Jet And Jones-Jig) produced distalization of the molars that was inevitably associated with loss of anchorage, reflected by mesial movement of the incisor and premolars. This adverse effect of the intraoral appliances and the longer treatment times and high dependence on patient compliance of extraoral distalization should be considered.
