| Abstract | ||
| Purpose: This study was carried out to assess treatment outcomes of Forsus Fatigue Resistant Device (FFRD) used in correction of skeletal Class II malocclusion through lateral cephalometric analysis. Subjects and methods: The study was conducted on ten Class II male patients. Treatment was followed through leveling and alignment till heavy 0.019 x 0.025-inch stainless steel archwires reached, then FFRD was inserted. The FFRD protocol ended when an overcorrected edge to edge incisal relation was obtained. Lateral cephalometric radiographs were taken before therapy and after completion of FRD therapy. The following skeletal parameters were measured from lateral cephalograms: SNA, SNB and ANB angles and linear measurement of total mandibular length, ramus height and corpus length. Measured dental parameters were maxillary and mandibular incisors inclination, amount of mesial movement of mandibular first molar, overjet and overbite. Results: The FFRD had a combined skeletal and dentoalveolar effect. It enhanced the sagittal skeletal relationships through maxillary restriction and mandibular forward repositioning. Dentoalveolar effects were significant in both arches and significant enhancement in overjet and overbite were found. Conclusions: The FFRD is effective in correcting Class II malocclusion through skeletal and dentoalveolar changes. | ||
