目的研究Spee曲线深度与颅颌面形态之间的关系。方法对2013—2014年在大连医科大学附属第二医院口腔科就诊的88例14~32岁错畸形患者的头颅侧位片及记存模型进行测量分析。将选取的13项头影测量指标与Spee曲线深度进行相关以及回归分析。结果 Spee曲线深度与性别因素无关。不同安氏分类间Spee曲线深度差异具有统计学意义,安氏Ⅱ类明显高于安氏Ⅲ类。SNA、ANB、AO-BO、后前面高比、ODI、上下唇长比与Spee曲线深度呈正相关关系,APDI、IMPA、颏唇角与Spee曲线深度呈负相关关系。结论颅颌面形态与Spee曲线深度之间存在相关性,在正畸诊疗过程中应加以考虑。
Objective To study the relationship between Spee curve depth and craniomaxillofacial morphology. Methods 88 cases of malocclusion from 14 to 32 years old in our department of dentistry, the Second Affiliated Hospital of Dalian Medical University from 2013 to 2014 were measured and analyzed. The selected 13 cephalometric indicators and Spee curve depth correlation and regression analysis. Results Spee curve depth has nothing to do with gender. The differences in Spee curve depth between different classes of Angle classifications were statistically significant, and Class Ⅱ was significantly higher than that of Class Ⅲ. The SNA, ANB, AO-BO, posterior anterior height ratio, ODI, upper and lower lip length ratio had a positive correlation with the depth of Spee curve. APDI, IMPA, chin angle and Spee curve depth had a negative correlation. Conclusion There is a correlation between craniomaxillofacial morphology and the depth of Spee curve, which should be considered in orthodontic treatment.
