[Treatment of Class II division 2 malocclusion with herbst appliance in young adults].

Abstract

OBJECTIVE:

To evaluate the effects of angle Class II division 2 malocclusion treated with Herbst appliance in young adults.

METHODS:

Cast splint Herbst appliance and multi-bracket appliance were used to treat 12 patients with Class II division 2 malocclusion aged from 16 to 25 years old. The lateral cephalograms were measured with Winceph 8.0 software and statistical analysis was carried out by SPSS 13.0 software.

RESULTS:

The changes in SNA, Co-Go, Go-Po after treatment had no statistical significance (P>0.05). The SNB increased and ANB decreased after treatment. Upper and lower incisors labially inclined and inter-incisor angle increased. Upper posterior teeth had distal movement, lower posterior teeth had mesial movement and extrusion. Mandibular plane angle and occlusal plane angle had clockwise rotation. The overbite decreased significantly, and the molar relationship changed from Class II to Class I in all patients.

CONCLUSION:

Herbst appliance combined with multi-bracket appliance can be used effectively for correcting Class II division 2 malocclusion in young adults.
