摘要
牙瘤是一种成牙组织的错构瘤或发育畸形,常导致恒牙迟萌或阻生。本文报道了1例与唇侧骨板密贴的牙瘤摘除及其伴随的鼻旁、上颌窦旁高位埋伏的尖牙拔除病例。利用数字化技术三维重建患者部分上颌骨、牙瘤、相关牙齿等毗邻解剖结构,精准确定病灶边界,设计最佳手术方案。采用双开窗法,通过上下两条路径,微创摘除病灶及埋伏牙,既保证了术区唇侧牙槽骨骨板的连续性,避免术后出现骨塌陷,也降低了上颌窦黏膜损伤、穿孔的风险,提高了手术效率,减少了手术创伤,符合微创牙槽外科理念。
Odontoma is a hamartoma or developmental malformation of dental tissues and often causes delayed or impacted permanent teeth.This paper reports a case of surgical removal of an odontoma that is closely attached to the labial bone plait and examines the extraction of accompanying high-impacted maxillary canine beside the nose and maxillary sinus.Digital technology was used in reconstructing a part of a patient's maxilla,odontoma,related teeth,and other adjacent anatomical structures,accurately determine the lesion boundary,and design an optimal surgical plan.The minimally invasive extraction of lesions and embedded teeth with a double-fenestration technique through the upper and lower paths not only preserved the continuity of the labial alveolar bone plate in the operative area and prevented postoperative bone collapse but also reduced the risk of maxillary sinus mucosal injury and perforation,improved surgical efficiency,and reduced the surgical trauma.These features were in line with the concept of minimally invasive alveolar surgery.
