Abstract

The effect of the Edgewise Bioprogressive Herbst appliance, as described by Dr. Terry Dischinger, was investigated on 24 Class II, Division 1 malocclusions. Mean pretreatment age of this sample was 11.2 months. All patients were treated by Dischinger with a Bioprogressive Herbst appliance. Lateral cephalographs taken before, after Herbst appliance therapy, and after edgewise treatment were traced, then digitized into Quick Ceph™. Measurements were computed by the computer software. The following results were found: 1) Average treatment time was 9 months. 2) An overcorrected Class I relationship was achieved. 3) Class II malocclusion was corrected by 4.5 mm skeletal alteration (63%), and 2.7 mm dental compensation (37%). 4) Mandibular growth alteration accounted for 5.5 mm of correction. 5) Herbst appliance effects were stable through the end of edgewise treatment. The Edgewise Bioprogressive Herbst appliance has been shown in this sample to be an effective appliance to correct Class II malocclusions in growing patients.
