[Photoocclusion as a complementary method in orthodontic diagnosis]

Area of Science:

• Dental occlusion research
• Orthodontic anomaly analysis
• Biomechanical dentistry

Context:

• Understanding occlusal contact patterns is crucial for diagnosing and treating orthodontic anomalies.
• Previous research has not comprehensively analyzed occlusal contact characteristics across diverse orthodontic anomaly groups.

Purpose:

• To analyze the number, intensity, and location of occlusal contacts within and between groups of orthodontic anomalies.
• To investigate occlusal contact variations relative to tooth type and dental arch segment.

Summary:

• This study analyzed occlusal contacts in 102 individuals (30 normal occlusion, 72 with anomalies) using photoocclusion and articulating paper.
• Crowding exhibited the highest number of occlusal contacts (16.41) among anomaly groups, while mandibular prognathism had the lowest (8.13).
• Significant differences were found in contact intensity and distribution across dental arch segments and tooth types, with molars bearing the highest load (64-65 kg/mm2).

Impact:

• Provides quantitative data on occlusal contact variations in different orthodontic anomalies.
• Informs clinical decision-making for orthodontic treatment planning and intervention.
• Contributes to a deeper understanding of the biomechanics of occlusion in anomalous dentition.
