Children in the mixed dentition grow rapidly, and various types of malocclusion often appear in this period. At the same time, there are many environmental factors affecting the development of the occlusion at this stage. Functional abnormalities related to lip, tongue, articulation and breathing, and impacted teeth should be actively intervened and blocked to avoid the continued development of the deformity. Appropriate orthopedic devices should be used in patients with skeletal malocclusion, if necessary, for growth modification and the influence of congenital factors and the prognosis of treatment should be fully evaluated. Over-intervention of the temporary malocclusions in the mixed dentition should be avoided. In conclusion, early orthodontic treatment in the mixed dentition requires a comprehensive assessment of the treatment need, risks, timing, cost and the ultimate benefit of the patient. The timing of orthodontic treatment is not the sooner the better. The indications must be strictly controlled, and the necessity and limitations must be carefully considered.
替牙期儿童生长迅速，这一时期常出现各类错牙合畸形。同时，此阶段有诸多环境因素影响牙合的发育。与唇、舌、发音及呼吸相关的功能异常以及阻生牙，均应积极干预并阻断，以避免畸形持续发展。对于骨骼性错牙合患者，如有必要应使用合适的矫形装置进行生长改良，且应充分评估先天性因素及治疗预后的影响。应避免对替牙期的暂时性错牙合过度干预。总之，替牙期的早期正畸治疗需要对治疗需求、风险、时机、成本及患者的最终获益进行全面评估。正畸治疗并非越早越好。适应证必须严格把控，对必要性和局限性必须审慎考量。
