A very rare case of bilateral supernumerary teeth in the maxillary canine region and its management through a 3-step-conservative approach and 5-year-follow up is presented in this report. A 7-year-old Caucasian boy presented with 2 erupted supernumerary primary maxillary canines (53s and 63s) and two unerupted supernumerary permanent maxillary canines (13s and 23s). The treatment was carried out in three steps. In the first step, we removed teeth 53s and 63s. As the second step, early removal of teeth 53 and 63 and cementation of a space maintenance appliance (Nance's arch) were performed. In the third step, teeth 13s and 23s were removed, and the Nance's arch was maintained until the complete eruption of teeth 13 and 23. The management of this case with a proper treatment plan enabled us to solve the problem without complex procedures.
本报告介绍了一例极为罕见的双侧上颌尖牙区多生牙病例，以及通过三步保守治疗方法进行处理并随访5年的情况。一名7岁的白种男孩，上颌有两颗已萌出的多生乳牙尖牙（53和63）以及两颗未萌出的多生恒牙尖牙（13和23）。治疗分三步进行。第一步，拔除53和63号牙。第二步，早期拔除53和63号牙并粘结间隙保持器（Nance弓）。第三步，拔除13和23号牙，并保留Nance弓直至13和23号牙完全萌出。通过适当的治疗计划对该病例进行处理，使我们能够在不进行复杂手术的情况下解决问题。
