Methods Thirty cases of patients aged from 10~15 years with skeletal class III malocclusion were selected and their remedy process was divided into two treatment phases,at the first phase treated with a bonded maxillary expansion and protraction about half a year,followed by the second phase treated with MEAW technology.

At first,the patients were treated with a bonded maxillary expansion and protraction,after about half a year, the patients were treated with MEAW technology,till an ideal occlusal relationships were .
