Short root anomaly (SRA) is a developmental anomaly in which the affected teeth present morphologically normal crowns and short, round roots. The exact cause of SRA is unknown. A case of an 11-year-old female patient with SRA is described. The patient presented short, round roots of all permanent teeth but first molars. Maxillary lateral incisors presented severe root resorption and mobility. Treatment plan included preservation of the maxillary lateral incisors by splinting them to their adjacent teeth using a stainless steel coaxial wire. A custom mouthguard for dental trauma protection was also constructed using a computer-aided design - computer-aided manufacturing (CAD-CAM) system in order to fabricate 3D-printed dental casts. At 2-year follow-up, the mobility of maxillary lateral incisors decreased, and the patient's dentition remained stable. Considerations regarding differential diagnosis, orthodontic management, and treatment options after an eventual loss of teeth are thoroughly discussed.
短根牙异常(SRA)是一种发育异常,其中受影响的牙齿冠部形态正常,但牙根短且呈圆形。SRA的确切病因尚不清楚。本文描述了一例11岁患有SRA的女性患者。该患者除第一磨牙外,所有恒牙的牙根均短且呈圆形。上颌侧切牙出现严重的牙根吸收和松动。治疗方案包括使用不锈钢同轴丝将上颌侧切牙与相邻牙齿固定在一起,以保留这些牙齿。还使用计算机辅助设计-计算机辅助制造(CAD-CAM)系统制作了一个定制的口腔防护器,用于预防牙齿外伤,以便制作3D打印的牙模。在2年的随访中,上颌侧切牙的松动度降低,患者的牙列保持稳定。文中还深入讨论了鉴别诊断、正畸治疗管理以及最终牙齿缺失后的治疗选择等相关问题。
