distal movement of posterior teeth, lateral movement of canines, labial movement of incisors, interproximal enamel reduction, removal of premolars, removal of one or two incisors, and various combinations of the above. Selecting the best treatment is often difficult, and all guidelines do not apply to every case. Treatment by extraction of one single mandibular incisor is not popular in the orthodontic profession despite the apparent advantages of the extraction in the region of crowding. A case report is presented one mandibular incisor extraction treatment of a 16 year-old female with a Class I malocclusion that shows a significant mandibular arch length deficiency and mandibular tooth-size excess. In this case, the degree of mandibular anterior dental crowding, existing mandibular tooth-size excess, and the dental midline discrepancy were indicated the extraction of one mandibular incisor.
目前,针对下颌前牙拥挤有多种治疗方法:后牙远中移动、尖牙唇向移动、切牙唇向移动、邻面釉质减径、拔除前磨牙、拔除一或两颗切牙以及上述方法的各种组合。选择最佳治疗方案通常很困难,而且所有指导原则并非适用于每个病例。尽管在下颌拥挤区域拔牙有明显优势,但在正畸领域,拔除单颗下颌切牙的治疗方法并不常用。本文报告了一例16岁I类错牙合女性患者单颗下颌切牙拔除治疗的病例,该患者存在明显的下颌牙弓长度不足和下颌牙量过大。在该病例中,下颌前牙拥挤程度、现有的下颌牙量过大以及牙中线差异表明需要拔除一颗下颌切牙。
