Traditionally, hand-wrist bone fragments are significantly related to the peak period of growth and development, which is the best index to judge bone age. However, some scholars hold that although the X-ray exposure to wrist is very small, it increases the exposure after all. Therefore, it is proposed to judge the stage and degree of growth and development by cervical vertebra images in lateral cephalogram. Clinical measurement of cervical vertebral bone age is mainly used to judge whether the craniofacial bone is in the peak growth period and predict the growth potential of mandible, so as to determine the appropriate treatment time and treatment mode. This paper mainly reviews the application of cervical vertebral bone age in orthodontic clinic from the above two aspects.
