Coronectomy is a widely-accepted technique available for the treatment of impacted wisdom teeth. The fundamental principle is to prevent trauma to the inferior dental nerve (IDN). Many publications have demonstrated its positive outcomes but there is no literature available regarding coronectomy of deciduous teeth. This case report highlights the complex approach to managing a severely infraoccluded 85 in the mixed dentition of a 10-year-old female. The report demonstrates and discusses the combined orthodontic and oral surgical approach to prevent damage to the IDN and to allow space for orthodontic movement. This case demonstrates how nerve sparing techniques in the mixed dentition are achievable.Clinical relevance statement When managing severely infraoccluded and impacted deciduous second molars, clinicians must be aware that the option of a coronectomy should be considered and may be the difference between sparing the nerve or causing permanent injury.Objective The reader should understand that coronectomy is a suitable treatment option in managing impacted deciduous teeth.
冠切除术是一种广泛接受的用于治疗阻生智齿的技术。其基本原则是防止损伤下牙槽神经（IDN）。许多出版物都证明了其积极效果，但关于乳牙冠切除术尚无文献报道。本病例报告重点介绍了一名10岁女性混合牙列中严重低位阻生的85号牙的复杂处理方法。该报告展示并讨论了正畸与口腔外科联合治疗方法，以防止损伤下牙槽神经并为正畸移动留出空间。本病例展示了在混合牙列中如何实现保留神经的技术。临床相关性声明 在处理严重低位阻生和萌出受阻的乳牙第二磨牙时，临床医生必须意识到应考虑冠切除术这一选择，这可能是保留神经或造成永久性损伤的关键区别。目的 读者应明白冠切除术是处理阻生乳牙的一种合适治疗选择。
