[A case report of anterior crowding treated without extraction].

Abstract

In orthodontic diagnosis, one of the most important factors is to decide whether or not to extract permanent teeth. There are many so-called borderline cases. In analyzing and determining whether or not to extract, discrepancy, profile, growth, and the patient's understanding and cooperation must be considered. We treated a borderline case without extraction, and established good occlusion and profile. Soft tissue changes are chiefly discussed.
