Abstract

Abstract: This article outlines the complete management process of a patient with skeletal class Ⅱ malocclusion in early permanent dentition, involving phase Ⅰ orthopedic treatment followed by phase Ⅱ fixed orthodontic treatment. The patient underwent phase Ⅰ orthopedic therapy to address three-dimensional skeletal discrepancy, followed by fixed orthodontics to correct malocclusion. As a result, significant improvements were observed in facial aesthetics, alignment, and occlusion.

Key words: skeletal class Ⅱ malocclusion, two-phase therapy
