In adult patients, managing this condition is further complicated by the absence of residual skeletal growth, limiting therapeutic options to orthodontic interventions and, in some cases, surgical procedures. Diagnosis in Class III adult patients requires distinguishing between skeletal malocclusion and dento-alveolar discrepancy. The combination of orthognathi...
