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

ABSTRACT:

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.

Material and methods

A total of 67 children with Angle Class II malocclusion comprised the study group in this trial. The participants were randomized into two equal-sized groups. In the early group (EG, n = 33), treatment was started after the eruption of the first upper molars. In the later-timed group (LG, n = 34), treatment was started 18 months later compared with the early group. Long-term effects were measured from dental casts taken at five time points between 7 and 18 years of age.
