To determine the frequency of orthodontic emergencies and their impact on the treatment progress caused by delayed appointments due to the lockdown during the COVID-19 pandemic.
Two hundred thirty-eight patients undergoing fixed orthodontic treatment participated in this cross-sectional study. A pre-structured questionnaire was divided into six parts (Part A-C comprised of orthodontic emergencies and Part D-F comprised of various adverse effects and impacts on treatment progress). Two specialist orthodontists performed clinical examinations to complete the questionnaire. The final data were expressed as frequency and percentage.
Maximum number of patients reported four months after lockdown. Nearly half of the patients reported debonding of at least one of the brackets. Loosening of molar bands and debonding of second molar tubes were observed in 12.6% and 18.9% of patients, respectively. Ligation method failures were reported in 41.2% of the patients. Patients fitted with transpalatal arch/lingual arch skeletal anchorage showed a failure rate of 26.1% and 10%, respectively. Almost 29% of the patient complained of discomfort due to distal wire impingement. Undesired tooth movements were seen in almost 25% of patients. Alignment, space closure, and settling of occlusion were affected in 47.6%, 17.4%, and 35.7% of patients, respectively.
This study helps to determine various types of adverse effects that can occur due to delayed appointments. The study's outcomes suggest that clinicians should be prepared to deal with future pandemics or other causes that might lead to delayed appointments.
确定在2019年冠状病毒病大流行期间因封锁导致预约延迟而引发的正畸急症的发生率及其对治疗进程的影响。
238名接受固定正畸治疗的患者参与了这项横断面研究。一份预先构建的问卷分为六个部分（A - C部分包括正畸急症，D - F部分包括各种不良反应及对治疗进程的影响）。两名正畸专科医生进行临床检查以完成问卷。最终数据以频率和百分比表示。
在封锁四个月后报告的患者数量最多。近一半的患者报告至少有一个托槽脱粘。分别有12.6%和18.9%的患者观察到磨牙带松动和第二磨牙管脱粘。41.2%的患者报告结扎方法失败。佩戴腭中缝扩展器/舌弓骨支抗的患者失败率分别为26.1%和10%。近29%的患者抱怨因远中弓丝压迫而不适。近25%的患者出现了不期望的牙齿移动。分别有47.6%、17.4%和35.7%的患者的排齐、间隙关闭和咬合调整受到影响。
本研究有助于确定因预约延迟可能出现的各种不良反应。研究结果表明，临床医生应做好应对未来大流行或其他可能导致预约延迟的情况的准备。
