Complicated crown-root fractures account for a small percentage of traumatic dental injuries seen in children; however, management of these injuries can be very challenging to clinicians. Factors such as complexity of the injury, patient's age and dentition stage, patient's cooperation, and parental demands may have some bearing on the type of treatment undertaken and its outcomes. In some children, these injuries may have significant impact on their quality of life. The purpose of this article is to describe two cases of complicated crown-root fracture which were successfully managed through orthodontic extrusion using a sectional fixed orthodontic technique. The basis for the treatment technique and its favourable outcomes were highlighted with its advantages and drawbacks.
复杂冠根折在儿童牙外伤中占比小；然而，对临床医生来说，处理这类损伤极具挑战性。损伤的复杂程度、患者年龄及牙列阶段、患者配合度以及家长要求等因素，可能会对所采取的治疗方式及其效果产生一定影响。对一些儿童而言，这些损伤可能会对他们的生活质量产生重大影响。本文旨在描述两例复杂冠根折病例，这两例病例通过使用片段式固定正畸技术进行正畸牵引而成功治愈。文中强调了该治疗技术的依据、良好效果及其优缺点。
