Abstract
The late mixed dentition stage of development, after the eruption of the first premolars, is a favorable time to start treatment to resolve crowding. This protocol offers the clinician choices. If nonextraction treatment is preferable, arch length preservation can provide the space for alignment in approximately 75% of all patients with crowding. If extraction treatment is indicated, the first premolars are available.
摘要
在第一前磨牙萌出后的牙齿发育晚期混合牙列阶段，是开始治疗解决牙列拥挤的有利时机。该方案为临床医生提供了多种选择。如果更倾向于不拔牙治疗，保留牙弓长度可为大约75%的牙列拥挤患者提供排齐牙齿的空间。如果需要拔牙治疗，第一前磨牙是可供选择的。
