Abstract: Objective: To investigate the clinical outcomes of combined application of Cone-beam CT (CBCT) and micro power system for extraction of type Ⅲ impacted supernumerary teeth for children. Methods: Children with type Ⅲ impacted supernumerary teeth who accepted the tooth extraction by CBCT and micro power system (implantology surgical unit) were collected. The accordance between CBCT and operation finding was analysed. The average operation time, post-operation pain and the complications of extraction were recorded. Results: The accordance was 100% between CBCT and operation finding. The average operation time was (27.5±6.1) min. Average Wong-Baker score for post-operative pain was (3.9±1.2) immediately after extraction and (1.3±1.1) 7 days after extraction. All wounds healed well without any complications. Conclusion: Combined application of CBCT and micro power system can reduce operation time to extract type Ⅲ impacted supernumerary teeth for children and reduce complications
