Abstract

The purpose of this report is to present the successful improvement of occlusal relationship and facial esthetics in class II division 1 malocclusion with severe labioversion of upper anterior teeth and severe overjet, and in class II
malocclusion
with
infraversion of bilateral maxillary canines by MEAW mechanics, which enables us to get effective distal en mass movement of maxillary dentition, with upper second molar extraction.
After treatment, there were natural contact points at canine and premolar regions, normal occlusalrelationship and treatment results, satisfied the gnathologic concept, in this 2 cases. Compared with the routine treatment with premolar
extraction,
the
treatment time and patients' discomfort were reduced. And the MEAW mechanics, which enables us to get effective distal en mass movement of maxillary dentition, resulted in reduction of the treatment time and getting the good treatment results.
Consequently, the major concerns in orthodontic treatment are appropriate diagnosis and treatment plan, so, the application of second molar extraction with appropriate case analysis and diagnosis is very helpful to orthodontic treatment.
