Introduction: The goals of this study were to compare the effects that cervical and high-pull headgear have on the vertical dimensions in Class II Division 1 patients during phase 1 treatment and to compare these effects with untreated predicted growth for the sample population.
Methods: Pretreatment and posttreatment cephalometric radiographs of children who had undergone Class II Division 1 correction with cervical (n = 22) or high-pull headgear (n = 19) were analyzed for the measurements that describe the changes in the vertical component of growth and mandibular position. The groups were matched for age (mean, 9 ± 2.5 years), treatment time (mean, 14 months), malocclusion, and similar skeletal features. The groups were compared with each other and also with an untreated growth model.
Results: Treatment with cervical headgear resulted in smaller increases in measurements that describe the vertical dimension than with high-pull headgear. Cervical headgear showed more favorable changes in mandibular growth that were statistically significant when compared with the untreated growth models.
Conclusions: In this study, the cervical headgear showed more control over the vertical dimension and produced more favorable changes in mandibular position by normalizing the occlusal plane. Compared with the untreated growth model, cervical headgear worked synergistically with growth to produce more optimal changes in mandibular position.

Class II malocclusion is a recurrent problem that may occur at a young age. If treated initially, the malocclusion can be corrected by redirecting the growth without invasive modalities and avoiding orthognathic surgeries. A female patient aged 10 years three months came to the department of orthodontics having a complaint of upper front teeth placed forwardly, diagnosed with skeletal class II due to retrusive mandible and vertical maxillary excess with hyper divergent growth pattern with increased anterior facial height, with Angle's molar class II division 1 malocclusion, increased overjet of 13 mm and overbite of 7 mm, acute nasolabial angle, deep mentolabial sulcus, and hyperactive mentalis.

Background: Lip incompetence is an important issue in orthodontics. No study has evaluated the effects of the combination of headgear + lip exercises on lip incompetence. Therefore, this study was conducted.

This report presents a case of a 16-year-old female patient with skeletal class II and dental class II division I malocclusion that was treated with fixed orthodontic appliances and through growth modulation. Two appliances were used: a Hyrax expander and a high-pull headgear with extraction. The treatment objectives of achieving a class I molar and canine relationship, resolving the crowding in the upper and lower arches, correcting the midline shift, and improving the patient's facial profile and lip position were achieved, resulting in a good occlusion with normal overbite and overjet.

Background: Cervical headgear (cHG) has been shown to be effective in Class II correction both with dental and orthopaedic effects but has traditionally been associated with vertical adverse effects in terms of posterior mandibular rotation.
Objective: To assess the treatment effects of cHG treatment in the vertical dimension.

A male child in his early adolescence was referred to the orthodontist to correct the proclined maxillary anterior teeth. Investigations concluded an excess maxilla, deficient mandible and remaining growth potential. The patient was treated with Twin Block functional appliance in combination with a high-pull headgear and later fixed pre-adjusted edgewise appliance to detail the occlusion.
