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

Cephalometric and Digital Dental Arch Characteristics Across Angle Malocclusion Groups in Orthodontic Patients From the Mekong Delta, Vietnam: a Cross-sectional Study

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

Inclusion Criteria:

• Adolescents aged 15-18 years.
• Permanent dentition.
• Diagnosed with Angle Class I, II, or III malocclusion.
• Complete lateral cephalometric radiographs and digital intraoral scans available.
• No previous orthodontic treatment.

Exclusion Criteria:

• Craniofacial syndromes or congenital anomalies.
• History of orthognathic surgery.
• Missing permanent teeth (excluding third molars).
• Poor-quality radiographs or digital scans.
• Incomplete clinical records.
