Experience in treatment of skeletal Class Ⅲ patients with asymmetric orthodontic tooth extraction
摘要
Abstract
Objective To investigate the feasibility of orthodontic treatment of skeletal classⅢwith asymmetric ortho-dontic tooth extraction. Methods A case of patient with skeletal class Ⅲ was examined by the clinical, model, X-ray and other examinations to analyze the causes and problems. The correct plan was made and the straight wire appliance was applied. Mandibular bilateral extraction and unilateral asymmetric tooth extraction method was used to adjust the un-coordinated sagittal relationship between the upper and lower mandible. Results After 25 months of treatment, the pa-tient's profile was improved. There was no skeletal ClassⅢ unique concave type profile appeared and good incisal guide and balanced occlusal relationship was obtained. Conclusion Maxillary teeth reduction of patients with skeletal ClassⅢshould be carefully used. But for some special cases, after a period of the treatment, asymmetric tooth extraction can be applied according to the upper dentition crowding, upper and lower midline and subsequent facial changes.关键词
