Effects of headgear timing on dental arch changes from 7 to 18 years of age: a follow-up study.

Background: Dental arch effects after cervical headgear (CHG) treatment have been researched from several different perspectives. However, the long-term effects of CHG timing are still unknown.

Objectives: To analyse the long-term effects of CHG timing on dental arches.

Dental arch effects after early and later timed cervical headgear treatment-a randomized controlled trial.

Background: Cervical headgear (CH) is a commonly used orthodontic appliance and its dentoalveolar changes are known. However, the effects related to gender and timing have gained less attention.

Objectives: To examine dimensions of dental arches among children with Class II occlusion without posterior mandibular rotation according to timing of Kloehn-type CH treatment.
