Intervention model: PARALLEL
Intervention model description: The total sample of patients will be randomly divided into three equal groups: Miniscrew: 7 patients will receive an intrusive force delivered by elastics from 2 miniscrews between mandibular lateral incisor and mandibular canine. Utility arch: 7 patients will receive an intrusive force delivered by intrusive utility arch. Nitinol reverse curve wire: 7 patients will receive an intrusive force delivered by Nitinol reverse curve wire.
