Abstract

Abstract:

Skeletal class Ⅲmalocclusion，manifested by excessive mandibular growth and/or hypoplasia of the maxilla，is typified by molar mesial occlusion，anterior crossbite，pronounced classⅢskeletal morphology，and mandibular prognathism，either with or without functional crossbite.This condition exerts a profound impact on oral functionality，facial esthetics，and psychological health，posing a significant therapeutic challenge that frequently necessitates orthognathic surgery.This case report presents an adult patient with skeletal class Ⅲmalocclusion who was treated with non-surgical，nonmicroimplant orthodontic camouflage therapy.The etiology is scrutinized，and the diagnostic process，differential diagnoses，and preventive strategies are deliberated to provide clinical practitioners with insights into effective management strategies.

Key words: Malocclusion, Skeletal classⅢ, Non-surgical, Orthodontic camouflage
