Minimally Invasive Robot-Assisted Supernumerary Tooth Extraction: A Case Report

Supernumerary teeth (STs) are a common dental anomaly that may lead to crowding, eruption disturbances, and orthodontic complications. Traditional extraction techniques often involve extensive bone removal, prolonged operative time, and increased trauma. The use of robotic-assisted surgery provides a more precise and minimally invasive approach. This case report describes the application of a robot-guided osteotomy system for ST extraction, highlighting its advantages in surgical precision and bone preservation. A 12-year-old male presented with an impacted ST in the anterior maxilla, confirmed by CBCT imaging. A robot-assisted surgical approach was planned and executed, consisting of the following steps: 1. Preoperative planning to determine the optimal surgical pathway. 2. Robot-assisted osteotomy using a trephine burr to create a controlled access channel. 3. Ultrasonic bone cutting to fragment and remove the ST while minimizing trauma to surrounding structures. 4. Bone grafting and wound closure, where the trephine-harvested bone was repositioned into the access channel before suturing. The procedure was completed in 45 minutes with minimal intraoperative bleeding. Postoperative recovery was uneventful, with no complications observed. Compared to conventional freehand techniques, robotic-assisted surgery enhances accuracy, reduces operative time, and preserves surrounding structures. The use of a guided osteotomy system allows for precise bone removal, minimizing unnecessary trauma. This case demonstrates the potential of minimally invasive, robot-assisted osteotomy in ST extraction. As robotic technology advances, its broader application in dental surgery may contribute to improved surgical outcomes and patient recovery.
