【摘要】 深度学习（DL）是人工智能（AI）的一个分支，通过模拟人脑中神经元的工作模式，可以处理更加复杂的任务，近年来，DL广泛应用于现代医学领域，是精准医疗的重要组成部分。头影测量片是正畸学最常用的影像资料之一，基于头影测量片的DL技术可以辅助正畸医生进行治疗的时机判定、方案设计和疗效评估等，为正畸治疗的精准化实施提供了有力技术支撑。该文介绍基于头影测量片的深度学习技术在口腔正畸治疗中的研究及应用，增进读者对于这门新技术的了解。更多还原

【Abstract】 Deep learning(DL) is considered as a branch of artificial intelligence(AI), which simulates the working pattern of neurons in human brain to deal with more complex tasks. In recent years, DL as the composition of precision medicine has been extensively applied in modern medicine. Cephalometric radiography is one of the most commonly used radiography method in orthodontics. Based on cephalograms, DL technology can assist orthodontists to determine the opportunity of orthodontic treatment, design the clinical protocols and to evaluate the therapeutic efficacy. Thus, DL technology is constructed to establish the precision medicine for orthodontic treatment. The present paper introduces the application of DL in orthodontics in order to recommend this new technology to dentists.更多还原
