Abstract:
Objective To investigate the treatment outcome of Class Ⅲ patients with dental,functional and mild skeletal mandibular asymmetry.Methods Thirty-five patients(14 males and 21 females)with dental,functional and mild skeletal mandibular asymmetry were selected.The age range of the patients Was 7-22 years with a mean age of 16.5 years.Dental mandibular asymmetry was treated with expansion of maxillary arch to help the mandible returning to normal position.Funetional mandibular asymmetry Was treated with activator or asymmetrical protraction and Class Ⅲ elastics. Mild skeletal mandibular asymmetry Waft.treated with camouflage treatment.Results Good occlusal relationships were achieved and facial esthetics Was greatly improved after orthodontic treatment in patients with dental and functionsl mandibular asymmetry.However,patients with skeletal mandibular asymmetry should be treated with both extraction and genioplasty.Conclusions Orthedontic treatment was suitable for patients with dental and functional mandibular asymmetry,while combined orthodontics and surgery could get good results in patients with skeletal mandibular asymmetry.
