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).
