The timing of orthodontic interventions has been a contentious topic for many years with early treatment to address or indeed to prevent skeletal discrepancies in all three spatial planes and to alleviate crowding in common practice. In terms of effectiveness, however, broadly speaking early intervention has not been shown to be superior to later intervention. As such, in view of the additional burden and duration of early intervention, the weight of evidence points to reserving early treatment for localized problems and specific situations with definitive treatment typically initiated in the late mixed or early permanent dentition.
多年来，正畸干预的时机一直是一个有争议的话题。在正畸治疗的常规操作中，早期治疗旨在解决甚至预防所有三个空间平面上的骨骼差异，并缓解牙列拥挤问题。然而，就有效性而言，从广义上讲，早期干预并未被证明优于晚期干预。因此，鉴于早期干预带来的额外负担和持续时间，证据表明应将早期治疗保留用于局部问题和特定情况，而确定性治疗通常在混合牙列晚期或恒牙列早期开始。
