Rationale:
Bone lid surgery (BLS) is minimally invasive surgery that removes the cortical bone and returns it to original position after removing lesions. However, jawbone lesions are completely covered with cortical bone, and it can be difficult to accurately determine the lesion position from the outside.
Patient concerns:
A 24-year-old Japanese woman, identified as having an impacted maxillary canine, was referred to our department. Periapical radiolucent lesion, with lateral incisor root absorption by canine compression, was confirmed.
Diagnosis:
The diagnosis was incisor root absorption due to an impacted canine.
Treatment:
As a potential solution, we performed navigation-assisted BLS.
Outcomes:
Using navigation, we could confirm the state of impacted tooth under the covered bone. We could establish reliable bone cutting and the removed cortical bone was successfully returned to the presurgical position.
Take-away lessons:
Navigation-assisted BLS for the removal of impacted teeth may increase surgical accuracy and minimize invasion.
