摘要:: Spee曲线主要描述矢状向下牙列的牙合面形态特征，在正畸和修复的临床治疗中都是需要考虑的重要因素，了解其发生发展的相关规律有助于不同患者个别正常牙合的实现。目前对于Spee曲线形成、生长发育规律及增龄性变化研究有限，文献复习结果表明，Spee曲线的形成是口颌面结构的生长、牙齿的萌出以及神经肌肉系统的发育之间相互作用的结果，也可能是由于发育过程中代偿机制的存在，生长发育过程中其深度主要随恒牙的萌出而发生变化，其他因素的影响还需进一步研究。生长发育结束后，可能由于牙齿的磨耗、第三磨牙的萌出等因素而发生改变。目前Spee曲线的生理性变化规律还没有形成共识，本文就有关研究进展进行总结，旨在为进一步研究及临床实践提供参考。

Abstract:: The curve of Spee mainly describes the morphological characteristics of the sagittal mandibular dentition, which is an important factor to be considered in the clinical treatment of orthodontics and restorative dentistry. Understanding the related rules of its occurrence and development is helpful for the realization of individual normal occlusion in diff erent patients. At present, there are limited studies on its formation, growth and development and age-related changes. Literature review shows that the formation of the curve of Spee is the result of the interaction between the growth of orofacial structures, teeth eruption and the development of the neuromuscular system, or it may be due to the existence of compensatory mechanism during growth and development. Its depth mainly changes with the eruption of permanent teeth, and the infl uence of other factors needs to be further studied. After the growth and development, the curve of Spee may change due to the wear of teeth, third molar eruption and other factors. At present, there is no consensus on the physiological change law of the curve of Spee, this paper summarizes the relevant research progress, aiming to provide references for further research and clinical practice.
