Abstract: Leveling the curve of Spee is both a routine step in orthodontic treatment and one of the goals of orthodontic treatment. After leveling the Spee curve，it is often seen that some patients will have recurrence. Understanding the factors that influence the formation of the curve of Spee contributes to the development of clinical treatment plans and the evaluation of efficacy. The factors that influence the curve of Spee are currently unclear. Therefore，this paper reviews the research progress of the relationship between Spee curvature and age as well as craniofacial morphology.

Key words: the curve of Spee, age, craniomaxillofacial morphology

摘要： 整平Spee曲线既是正畸治疗的常规步骤，也是正畸治疗的目标之一。在整平Spee曲线后，临床上常可见部分患者有复发现象。了解影响Spee曲线形成的因素有助于临床上治疗计划的制定及疗效的评估，而目前对于影响Spee曲线形成的因素尚未完全明确。文章就Spee曲线与年龄及颅颌面形态关系的研究进展做一综述。
