Summary
Assessing alveolar base widths is crucial for orthodontic limits. This study found no correlation between anterior and posterior base widths, indicating a need for new predictive indicators in orthodontics.
Area of Science:
- Orthodontics and Dental Anthropology
- Investigating craniofacial morphology and alveolar bone dimensions.
Background:
- Alveolar base width assessment is vital for determining incisor root movement limits.
- Current methods lack evaluation of facio-lingual base widths for premolars and molars.
Purpose of the Study:
- To assess associations between anterior and posterior alveolar base widths.
- To explore correlations between posterior alveolar base width and cephalometric measurements.
Main Methods:
- Comparative measurements on 40 adult Thai skulls and mandibles.
- Utilized lateral cephalometric radiographs, linear tomography, and direct measurements.
- Examined dento-alveolar and basal structures.
Main Results:
- Significant variation observed in facio-lingual alveolar base widths.
- No significant correlation found between anterior and posterior alveolar base widths.
- Inverse correlations noted between mandibular incisor base width and specific cephalometric angles (FP-MP, PP-MP), and maxillary incisor base width and gonial angle.
- No cephalometric indicators reliably predicted posterior alveolar base width.
Conclusions:
- Posterior alveolar base width cannot be reliably predicted using current cephalometric indicators.
- Further research is necessary to identify effective assessment indicators for posterior alveolar base width.
- Understanding these dimensions is critical for precise orthodontic treatment planning.
