Abstract

BACKGROUND The extraction of impacted supernumerary teeth requires precision and accuracy to mitigate iatrogenic damage to crucial anatomical structures during dental surgical procedures, thereby enhancing postoperative healing outcomes. Dynamic navigation systems (DNS) have been applied in dentistry in maxillofacial fractures, orthognathic surgery, root canal treatment, and endodontic surgery. CASE REPORT A 22-year-old female patient visited our department to assess and manage unerupted third molars. An initial cone beam computed tomography (CBCT) scan was obtained. Radiographic and clinical examinations showed the presence of a supernumerary tooth impacted on the lingual side between the root of the lower second premolar and the lower first molar and bilateral lower impacted third molars. The patient agreed to removal of these teeth. To perform the treatment planning of this case and to guide the surgeon intraoperatively, a dynamic surgical navigation system was recommended for surgical extraction of a supernumerary tooth and the impacted third molars. CONCLUSIONS The dynamic navigation system coupled with a high-speed contra-angle handpiece for the extraction of supernumerary teeth is a personalized, digitally-driven, precise, minimally invasive, and efficient treatment approach. In this case, the DNS and the high-speed contra-angle handpiece were seamlessly integrated to facilitate visualization of the surgical procedure, thereby safeguarding of surrounding vital anatomical structures while enhancing patient comfort.
