Objective To explore the clinical effect of minimally invasive technique on impacted teeth extraction.Methods A total of 80 patients with impacted teeth admitted to our hospital from January 2019 to February 2020 were selected as the research subjects and divided into two groups by odd or even number, with 40 cases in each group. Patients in the control group were treated with traditional tooth extraction. Patients in the observation group were treated with minimally invasive. After treatment, the visual analogue scale (VAS), alveolar socket integrity, operation time, incomplete extraction socket, satisfaction, oral health impact profile (OHIP-14) scale and complications were compared between the two groups. Results After treatment, the VAS score ([1.12±0.22]points), alveolar socket integrity score([1.05±0.33]points), the incidence of incomplete extraction socket (2.50%), physiological pain ([1.45±0.19]points), social disorder ([1.19±0.22]points), functional limitation ([2.39±0.42]points), physical disorder ([2.05±0.16]points) and total incidence of complication (2.50%) in the observation group were all lower than those of the control group ([2.65±0.43]points, [2.76±0.41]points, 20.00%, [2.86±0.57]points, [3.46±0.75]points, [4.85±0.61]points, [3.58±0.43]points,27.50%), and the differences were statistically significant (P<0.05). The operation time of the observation group([34.84±3.56]min) was shorter than that of the control group ([47.76±4.23]min), and the difference was statistically significant (P<0.05). The satisfaction of the observation group (100.00%) was higher than that of the control group(80.00%), and the difference was statistically significant (P<0.05). Conclusion In the extraction of impacted teeth, the effect of minimally invasive treatment is better than the traditional tooth extraction.
