Abstract

The objective of this case report was to discuss ISW wire (Improved Super-elastic Ti-Ni alloy Wire) for the treatment of adult skeletal class II protruded extraction case. An adult female aged 35 years 9 months who came to our clinic with a chief complaint of protruded teeth and for esthetic consultation. Clinical examination revealed left side Class II molar relationship tendency with Class II canine relationship (right side: molar Class I, canine Class I), and moderate crowding over the anterior region. Active treatment included anterior retraction with gable bend and long hook for space closure after bilateral maxillary and mandibular bicuspids extraction. ISW curve was performed over the upper and lower anterior teeth. Treatment was completed within 28 months and a stable occlusion was achieved after the active treatment.

Introduction

The treatment of an adult skeletal class II protruded teeth with retroclined incisor tendency is usually a challenge to orthodontists. The clinical manipulation of inclination, also can be interoperated as controlled tipping, over the anterior teeth during space closure is very critical for bilateral maxillary and mandibular bicuspids extraction case [1]. Clinical examination revealed left side Class II molar relationship tendency with Class II canine relationship (right side: molar Class I, canine Class I) [2-3], and moderate crowding over the anterior region. Our concept is to use rather optimal mechanism to achieve the goal of anterior teeth bodily movement without the use of temporary anchorage device (TAD). Active treatment included anterior retraction with gable bend and crimp able long hook for space closure after bilateral maxillary and mandibular bicuspids extraction. ISW curve was performed over the upper and lower anterior teeth. Finally, a desirable esthetic outcome was achieved and the patient was pleased with the treatment result.
