Abstract：
BACKGROUND: Maxillary central incisors (MCI) are the third most impacted teeth. Timely multidisciplinary management is indicated as unerupted incisors can cause functional- and appearance-related distress.
OBJECTIVE: To assess the patient journey for children with unerupted MCI, including referral, clinical assessment, surgical management and follow-up treatment, and highlight areas for improvement, as well as identify factors impacting orthodontic treatment burden (OTB).
METHODS: A retrospective service evaluation of children aged 6-16 years who had surgical management of unerupted MCI under general anaesthetic (GA) between 2018 and 2021.
RESULTS: Fifty-two children with 62 unerupted MCI were identified. Mean age at referral was 8.8 years. Most children (82.7%) had supernumerary teeth in the anterior maxilla. Mean time between listing for GA and surgery increased from 4.3 to 15.2 months following the COVID-19 lockdown. Mean age at surgery was 10.4 years. Supernumerary removal and incisor exposure and bond was the most common treatment (56.6%). Most patients required hospital orthodontic treatment post-surgery (65.4%).
CONCLUSIONS: Most children referred were below 9 years (60.1%); these children had reduced OTB compared to those who had been referred at an older age. Stage of root development was also a significant predictor in OTB. An unexpected finding was that conical supernumeraries were found to prevent MCI eruption.

摘要：
背景：上颌中切牙（MCI）是第三大受累的牙齿。及时进行多学科管理，因为门牙未开可引起功能和外观相关的困扰。
目的：评估未爆发MCI患儿的患者旅程，包括转诊，临床评估,手术管理和随访治疗，突出需要改进的地方，以及确定影响正畸治疗负担（OTB）的因素。
方法：对2018年至2021年在全身麻醉（GA）下接受手术治疗的6-16岁儿童进行回顾性服务评估。
结果：确定了52名儿童，其中62名未爆发的MCI。转诊时的平均年龄为8.8岁。大多数儿童（82.7％）在前上颌骨有多余的牙齿。在COVID-19封锁后，GA上市和手术之间的平均时间从4.3个月增加到15.2个月。手术时的平均年龄为10.4岁。多余的去除和门牙暴露和粘结是最常见的治疗方法（56.6％）。大多数患者在手术后需要医院正畸治疗（65.4％）。
结论：大多数转诊儿童年龄在9岁以下（60.1%）；与年龄较大的转诊儿童相比，这些儿童的OTB减少。根系发育阶段也是OTB的重要预测指标。一个意想不到的发现是，发现圆锥形的超数可以防止MCI爆发。
