Class II Treatment in Growing Patients: Preliminary Evaluation of the Skeletal and Dental Effects of a New Clear Functional Appliance

Objective: The purpose of this retrospective preliminary study was to analyze the skeletal and dentoalveolar effects a new clear functional appliance in sample patients close growth spurt with class II malocclusion attributable mandibular retrusion. Materials methods: A growing underwent Class correction using F22® (Sweden Martina, Due Carrare (PD), Italy) Young, realized combining aesthetic characteristics aligner structural features appliance. For each patient, digital setup performed by single operator plan advancement therapeutic position. Cephalometric analysis before after treatment performed. statistical evaluate dental changes associated Young device, whether there were statistically significant differences anatomical measurements between beginning end treatment. Results: 15 patients, 7 females 8 males average age 10.3, treated for an period 10 months ± 0.5 (maximum 11.5 months, minimum 10.5 months). data showed that SNB angle increase from T0 T1, leading reduction ANB angle. Values mandible length, both total (Co-Gn) at base (Go-Pg), significantly increased. Conclusions: According study, is effective promoting when used near pubertal peak. device comfortable aesthetic, which certainly promoted patient compliance, key factor success.
