在此，我们描述了一名因外伤性失去上中切牙和上颌前突的青春期女孩的正畸治疗。立即更换中切牙，并用半刚性夹板固定12天，然后进行牙髓治疗。 4年后，患者出现严重的牙根吸收和牙周组织退化，并拔牙，同时患者还出现上颌前突，下牙弓严重拥挤。治疗目标是通过上牙弓颊侧段的近中移动来封闭间隙，并通过拔除下双尖牙来消除拥挤。实现了良好的咬合，并用侧切牙替代了丢失的中牙。
Herein, we describe orthodontic management for an adolescent girl with traumatic loss of the upper central incisors and maxillary protrusion. The central incisors were immediately replaced and fixed with application of a semi‐rigid splint for 12 days, then endodontically treated. Severe root resorption and degeneration of periodontal tissue were noted after 4 years and the teeth were extracted, while the patient had also developed maxillary protrusion with severe crowding in the lower arch. The treatment objectives were to close the spaces by mesial movement of the buccal segment in the upper arch and eliminate crowding by extraction of the lower bicuspids. Favorable occlusion was achieved as was substitution with the lateral incisors for the lost central teeth.
