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.
牙瘤是一种牙源性组织的错构瘤或发育畸形，常导致恒牙迟萌或阻生。本文报道了一例唇侧骨板附着的牙瘤的手术切除，并探讨了在鼻旁和上颌窦处高位埋伏上颌尖牙的拔除。数字化技术被用于重建患者上颌骨、牙瘤、相关牙齿和其他相邻解剖结构的一部分，准确确定病变边界，并设计最佳手术方案。通过上下路径的双开窗技术微创切除病变和埋伏牙，不仅保持了手术区域唇侧牙槽骨板的连续性，防止术后骨塌陷，还降低了上颌窦黏膜损伤和穿孔的风险，提高了手术效率，减少了手术创伤。这些特点符合微创牙槽外科的理念。
