Safer alternative for extraction of impacted supernumerary teeth of a patient in the mixed dentition stage with the aid of an image-guided operating system

Supernumerary teeth can exist throughout the mouth and are more common in the maxilla than in the mandible.1,2 During the mixed dentition stage, impacted supernumerary teeth that could block the eruption of permanent teeth, or interfere with the establishment of occlusal relations, should be extracted immediately. There is a risk of injury to the permanent tooth germs or of removing the wrong teeth in mixed dentition, because of the difficulty of locating the permanent tooth germs and the impacted teeth precisely from routine radiographs.
