RESUMO
Objective:To evaluate the clinical effect of minimally invasive extraction of impacted supernumerary teeth.Methods :35 cases of impacted supernumerary teeth were included.Excluding extraction contraindications,preoperative X-ray or dental CT examina-tion was executed to find out the location of the impacted teeth and adjacent anatomical structures.According to the location,operation approach was selected to extract the impacted supernumerary teeth using minimally invasive apparatus.Intraoperative and postoperative feeling of the patients and the complications were recorded.Results:Operation time lasted from 1 0 to 40 minutes,average 1 5 minutes. All patients maintained good comfort in the operation.8.6% patients had postoperative adverse reactions such as mild pain and discom-fort.None had serious reactions.Conclusion:Minimally invasive extraction of impacted supernumerary teeth has less complication and less uncomfort.
