Brief Summary
The aim of the present study was to retrospectively compare the clinical use of high-pull headgear versus AMCOP bioactivators for hyperdivergent pediatric patients. Cephalometric radiographs from pediatric patients treated at the Unit of Orthodontics and Pediatric Dentistry, Section of Dentistry, Department of Clinical, Surgical, Diagnostic and Pediatric Sciences, University of Pavia, Pavia, Italy and at the private practice of Dr. Cardarelli, Isernia, Italy will be collected. Cephalometric tracing from Giannì analysis will be performed at the baseline (T0) and after 18 months of treatment (T1).

Baseline (T0) and after 18 months (T1)
Linear regressions
Linear regressions among the variables of the study and sex, age, and group of the patients will be performed.

Eligibility Criteria
Orthodontic patients
You may qualify if:
- mixed or permanent dentition
- skeletal class II malocclusion diagnosed with ANB angle \> 4° from cephalometric radiograph
- skeletal hyperdivergency calculated from AnsPns\^GoGn angle \> 25°, and at least S-Ar\^Go \> 149° or Ar-Go\^Gn \> 137°
You may not qualify if:
- lack of compliance in the use of the orthodontic appliance
- syndromic patients, cleft lip or cleft palate, severe malformations and asymmetries of the jaws.
