Supernumerary teeth usually result in retarded eruption, malocclusion, poor esthetics, and cyst formation. Management involves surgical extraction, which can be challenging in certain complicated cases owing to the risk of injury to young permanent tooth germs or fragile roots. The present report describes a novel preoperative computer-assisted and intraoperative navigation-guided surgical treatment for a case of complicated impacted supernumerary teeth. The report highlights accurate tooth location and minimal invasion with use of the navigation-guided system. Moreover, it discusses various treatment considerations during such a procedure.
多生牙通常会导致萌出延迟、错牙合畸形、美观欠佳以及囊肿形成。治疗方法包括手术拔除，在某些复杂病例中，由于存在损伤年轻恒牙胚或脆弱牙根的风险，手术拔除具有挑战性。本报告描述了一例复杂埋伏多生牙的新型术前计算机辅助和术中导航引导的手术治疗。该报告强调了使用导航引导系统时牙齿定位准确且侵入性最小。此外，还讨论了在此类手术过程中的各种治疗注意事项。
