Cephalometric and Digital Dental Arch Characteristics Across Angle Malocclusion Groups in Orthodontic Patients From the Mekong Delta, Vietnam

This clinic-based cross-sectional study compared skeletal, dental, soft-tissue, and digital dental arch characteristics among adolescents aged 11-18 years with Angle Class I, Class II, and Class III malocclusions in the Mekong Delta, Vietnam. Lateral cephalometric radiographs and three-dimensional intraoral scans were used to evaluate craniofacial morphology and dental arch dimensions. Significant differences were observed in sagittal skeletal relationships, vertical facial characteristics, dentoalveolar measurements, overjet, overbite, and maxillary arch dimensions among the three malocclusion groups. These findings provide clinically relevant information that may support individualized orthodontic diagnosis and treatment planning for adolescents in comparable clinical settings, while not representing population norms or regional prevalence estimates

Treatment and study plan

Primary outcomes

  1. Cephalometric Characteristics

    Time frame: Baseline

    Overall cephalometric characteristics measured from standardized lateral cephalometric radiographs and compared among Angle Class I, Class II, and Class III malocclusion groups using predefined cephalometric variables according to the study protocol.

Secondary outcomes

  1. Digital Dental Arch Characteristics

    Time frame: Baseline

    Overall digital dental arch characteristics measured from three-dimensional intraoral digital models and compared among Angle Class I, Class II, and Class III malocclusion groups according to the study protocol.
