The knowledge of the skeletal maturation and the stage of the growth of the patients seeking orthodontic treatment are of great value in planning efficient orthodontic therapy. However, different craniofacial structures of patient show variation in growth potential. The routine use of hand-wrist radiograph for growth prediction exposes the patient to extra radiation. Cervical vertebrae in the lateral cephalograph have been recommended as an alternative method. The pubertal growth spurt is a vital period in the orthodontic treatment and should be kept in mind when planning orthodontic treatment in growing children. One of the main objectives of taking hand and wrist radiograph is to determine the amount of growth and get used of it in patients with skeletal discrepancy during adolescence. Further, this will help in the selection of the appliances required, the course of the treatment and the retention after active orthodontic therapy.
了解寻求正畸治疗患者的骨骼成熟度和生长阶段，对于规划高效的正畸治疗具有重要价值。然而，患者不同的颅面结构显示出生长潜力的差异。常规使用手部 - 腕部X线片进行生长预测会使患者受到额外辐射。有人推荐在头颅侧位片上观察颈椎作为一种替代方法。青春期生长高峰是正畸治疗的关键时期，在为正在生长的儿童规划正畸治疗时应予以考虑。拍摄手部和腕部X线片的主要目的之一是确定生长量，并在青春期骨骼差异患者中加以利用。此外，这将有助于选择所需的矫治器、确定治疗过程以及在积极的正畸治疗后进行保持。
