Abstract
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.
