摘要

Supernumerary teeth (STs) in children may cause delayed eruption or malocclusion or may even develop into a cyst. Recent reviews suggest early removal of unerupted STs. However, locating the target teeth and avoiding damage to adjacent permanent teeth and vital tissues are major concerns in early treatment. We present the case of a 10-year-old boy with five STs over four quadrants of the canine-premolar area. Surgical removal of all STs was performed under general anesthesia with a dynamic surgical navigation system (DSNS). The surgery proceeded without complications, and the patient recovered well. Early ST removal surgery in children is challenging. Therefore, a DSNS represents a promising solution and a minimally invasive intervention for multiple STs.

兒童患有贅生齒往往會造成萌發問題、咬合不正、抑或是發展成囊腫。回顧文獻，未萌發的贅生齒仍建議早期治療。然而在乳牙齒列或是混和齒列進行贅生齒移除手術，贅生齒的定位、如何避免傷害到恆牙牙胚及其他重要解剖組織會是一項重大的難題。此份病例報告呈現一位10歲的男孩於口內四個象限的犬齒－小臼齒區發現五顆贅生齒。安排於全身麻醉之下使用動態手術導航系統拔除所有的贅生齒。兒童的贅生齒移除手術是很有挑戰性的。對於多重贅生齒移除這樣複雜的手術，動態手術導航系統是一個很有發展性並可以協助降低侵犯性的選擇。
