摘要

摘要埋伏切牙牙根扩张的临床处理具有挑战性。本病例报告介绍了一名上颌中切牙深度嵌塞、旋转和扩张的青春期女性患者的治疗方法，并回顾了目前关于该异常的定义、患病率、病因、诊断和治疗的文献。由于嵌塞深和严重移位，在矢状面旋转100度后，经过两期手术暴露，成功矫正了阻生和扩张的门牙。采用弹弓弹簧和背驮式矫治器技术将牙抬高。扩张的切牙被成功地保存并重新安置在牙弓中。术前和术后的CBCT扫描显示，复位的牙齿没有明显的牙根吸收。

Root Dilaceration: A Case Report and Literature Review

Abstract The clinical management of impacted incisors affected by root dilaceration is challenging. This case report presents the treatment of an adolescent female patient who presented with a deeply impacted, rotated and dilacerated maxillary central incisor and also reviews the current literature on the definition, prevalence, aetiology, diagnosis, and treatment of the anomaly. The impacted and dilacerated incisor was successfully orthodontically treated following a two-stage surgical exposure and after being rotated 100 degrees in the sagittal plane (due to the deep impaction and severe displacement). A Ballista spring and piggyback appliance technique were used to elevate the tooth. The dilacerated incisor was successfully preserved and relocated in the dental arch. The pre-operative and post-operative CBCT scans showed no significant root resorption of the repositioned tooth.

期刊介绍： The Australasian Orthodontic Journal (AOJ) is the official scientific publication of the Australian Society of Orthodontists. Previously titled the Australian Orthodontic Journal, the name of the publication was changed in 2017 to provide the region with additional representation because of a substantial increase in the number of submitted overseas'' manuscripts. The volume and issue numbers continue in sequence and only the ISSN numbers have been updated. The AOJ publishes original research papers, clinical reports, book reviews, abstracts from other journals, and other material which is of interest to orthodontists and is in the interest of their continuing education. It is published twice a year in November and May. The AOJ is indexed and abstracted by Science Citation Index Expanded (SciSearch) and Journal Citation Reports/Science Edition.
