Micro-implant를 이용한 Angle Class Ⅱ급 2류 성인 환자의 치험례

Abstract

Angle Class II division 2 malocclusions are rare in Korean patients. But, they are not so easy cases for orthodontic treatment, because the maxillary molars have to be ditally retracted without adverse reciprocal effects. Micro-implant anchorage provided absolute anchorage for correction of Class II canine and molar relationships and deep-overbite. Therefore, a successful and esthetic nonextraction orthodontic treatment of Class II division 2 was established in a 27 year-old woman within relatively short time.
