Advances in Diagnosis and Treatment of Skeletal Class III Malocclusion

Abstract

Skeletal Class III malocclusion, a complex dentofacial deformity, significantly affects individuals’ facial appearance and oral function. It presents major challenges in orthodontic treatment for youngsters because of unpredictable jaw growth patterns and variable outcomes. Recent advances in specific radiographic features have enhanced diagnostic accuracy and treatment predictability, garnering widespread interest from researchers. This lecture examines the key clinical and radiographic markers essential for diagnosing and treating skeletal Class III malocclusion. Through detailed analysis of lateral cephalograms, crucial variables for facial type classification, growth prediction, and decisions regarding tooth extraction and jaw surgery are discussed. Moreover, recent findings from 3D imaging (CBCT) and MRI reveal distinctive features of Class III malocclusion, offering opportunities for more precise treatment planning.
