ABSTRACT
AIM: The aim of the study was to investigate the association between maxillary impacted canine and sagittal and vertical skeletal patterns (VSPs).
MATERIALS AND METHODS: This study included 82 individuals, who presented with maxillary impacted canines. Assessment of impaction included type, location, alpha angle, and distance “d“. Sagittal skeletal patterns were evaluated by measurement of sella, nasion, point A (SNA), sella, nasion, and point B (SNB), anteroposterior relationship between A-point and B-point (ANB), A point to nasion perpendicular to Frankfort horizontal, and Pogonion to nasion perpendicular to Frankfort horizontal. Three angles were used to analyze VSPs (SN-MP, FH-MP, and MM angle). Cephalometric measurements were processed using OnyxCeph3TM software. Associations between impaction type, location, and skeletal patterns, as well as the relationship between impaction type, location, and impaction-related variables (alpha angle and distance d) were all measured. Correlations were established between impaction-related variables and skeletal measurements.
RESULTS: Class III sagittal skeletal pattern was the most frequent (41.5%), while normodivergent vertical skeletal pattern (VSP) was predominant (53.6%). Bilateral impactions were associated with lower mean SNA and SNB angle measurements compared with unilateral impactions. A significant positive correlation was found between the alpha angle and distance d. No statistical association was observed between impaction-related variables and skeletal patterns.
CONCLUSION: A prognathic maxilla and hyperdivergent skeletal patterns were less frequently associated with maxillary impacted canines. Both jaws exhibited greater retrusion in bilateral cases compared with unilateral maxillary impacted canines. Although certain trends in skeletal patterns were noted, these patterns are not directly associated with maxillary impacted canines and, therefore, lack predictive reliability.
CLINICAL SIGNIFICANCE: Skeletal analysis alone may not reliably predict impactions, which supports the need for a comprehensive diagnostic approach that can guide orthodontic treatment for maxillary impacted canines in Yemeni adults.
