Summary

The study was directed to compare the treatment outcomes of subjects with Class II malocclusion who were treated with Herbst appliance before and after puberty.

Detailed description

Thirty-six Class II patients were randomly selected and divided into two groups based on their stage of skeletal maturation: pre-pubertal group (18 patients, mean age 9.15± 1.5 years) and post-pubertal group (18 patients, mean age 16.3 ± 1.0 years). All patients were treated with metallic splint supported Herbst IV appliance. Pretreatment and post-Herbst IV treatment cone beam CT(CBCT) scans were obtained for both groups. Dentoskeletal and TMJ measurements made on the CBCT scans were analysed.

Conditions

• Class II Malocclusion, Division 1
