Summary
Centrographic analysis provides reference values for Shanghai adults with normal occlusion. Findings indicate differences in mandibular position and incisor inclination compared to Caucasians.
Area of Science:
- Orthodontics
- Anthropometry
- Cephalometrics
Background:
- Establishing normative data for craniofacial morphology is crucial in orthodontics.
- Centrographic analysis offers a quantitative method to assess skeletal and dental relationships.
Purpose of the Study:
- To determine the reference values for centrographic analysis in Shanghai adults with normal occlusion.
- To compare these values with those of Caucasian populations.
Main Methods:
- Lateral cephalograms of 75 Han Chinese adults (18-21 years) with normal occlusion were analyzed.
- Centrographic analysis was performed, and data were statistically compared to Caucasian norms using SAS 9.2.
Main Results:
- Reference values for centrographic analysis in Shanghai adults were established.
- Specific positional data for facial and dental centroids were determined.
- No significant gender-based differences were observed (P>0.05).
Conclusions:
- Shanghai adults exhibit a relatively forward mandibular position compared to Caucasians.
- Labial inclination of incisors and slight convexity of the lower facial third were noted.
