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.

上颌阻生犬与一组也门成年人的垂直和矢状骨骼模式之间的关系。
目的:本研究的目的是探讨上颌阻生犬与矢状和垂直骨骼模式(VSPs)之间的关系。材料和方法:本研究包括82例上颌阻生犬科患者。撞击的评估包括类型、位置、α角和距离“d”。通过测量鞍、鼻、A点(SNA)、鞍、鼻、B点(SNB)、A点与B点(ANB)的正相关关系、A点与鼻垂直于法兰克福水平、Pogonion与鼻垂直于法兰克福水平来评估矢状面骨骼模式。采用三个角度(SN-MP、FH-MP和MM角度)分析VSPs。使用OnyxCeph3TM软件进行头颅测量。我们测量了嵌塞类型、位置和骨骼模式之间的关联,以及嵌塞类型、位置和嵌塞相关变量(α角和距离d)之间的关系。在撞击相关变量和骨骼测量之间建立了相关性。结果:ⅲ类矢状骨型最常见(41.5%),而正常垂直骨型(VSP)居多(53.6%)。与单侧嵌塞相比,双侧嵌塞的平均SNA和SNB角度测量值较低。α角与距离d之间存在显著的正相关。碰撞相关变量与骨骼模式之间没有统计学关联。结论:上颌前突和超发散的骨骼模式较少与上颌阻生犬相关。与单侧上颌阻生犬相比,双侧双颌表现出更大的后缩。虽然骨骼模式的某些趋势被注意到,但这些模式与上颌阻生犬没有直接联系,因此缺乏预测可靠性。临床意义:单独的骨骼分析可能不能可靠地预测嵌套,这支持需要一个全面的诊断方法,可以指导也门成人上颌嵌套犬的正畸治疗。如何引用本文:Al Eryani FA, Al Akwa'a AA, Ishaq RA等。上颌阻生犬与一组也门成年人的垂直和矢状骨骼模式之间的关系。[J]现代医学学报,2015;26(2):178-183。
