Abstract

Abstract: Objective: To explore and evaluate the clinical effect of digital positioning guide template in extraction of complete bone impacted teeth based on CBCT and CAD/CAM technology. Methods: A total of 36 patients treated in the Oral and Maxillofacial Surgery Clinic of the First Affiliated Hospital of Xinjiang Medical University from January 2020 to December 2020 were selected, who used digital positioning guide template to extract complete bone impacted teeth, including 15 males and 21 females. The teeth positioning time, operation time, fenestration area, operative blood loss, operative and postoperative complications were recorded. Results: All patients successfully completed the operation. The average time to position the complete bone impacted teeth using the digital positioning guide plate was (1.85±0.64) min, the average operation time was (24.15±2.88) min, the average operative fenestration area was (63.81±8.69) mm², and the average operative blood loss was (8.87±1.89) mL. There were no operative complications, such as positioning deviation, adjacent tooth injury, restricted mouth opening, and nerve and blood vessel damage. One patients had air leak of maxillary sinus after the extraction, and one patient had infection of the extraction wound 5 days after the operation. Conclusion: The use of digital positioning guide template can achieve good clinical results in minimally invasive extraction of complete bone impacted teeth.
