目的探讨微动力系统微创拔牙术联合舒适化干预治疗下颌阻生智齿患者的效果。方法选取220例下颌阻生智齿患者作为研究对象，根据信封法将其分为观察组和参照组，每组110例，参照组采用传统拔牙术治疗，观察组采用微动力系统微创拔牙术联合舒适化干预治疗。比较两组患者围手术期相关指标（手术时间、术中出血量和骨愈合时间）、治疗后1周的疼痛程度［视觉模拟评分法（VAS）评分］、恐惧情况［畏惧调查量表－牙科分量表（CFSS-DS）评分］和舒适度（采用舒适状况量表评价，包括环境、心理、生理和社会文化4个维度），以及术后并发症发生情况。结果观察组患者手术时间、术中出血量、骨愈合时间短于或少于参照组（P<0.05）；治疗后，两组患者疼痛VAS评分和CFSS-DS评分较治疗前降低，且观察组患者上述评分低于参照组（P<0.05）；治疗后，两组患者环境、心理、生理和社会文化维度评分高于治疗前，且观察组高于参照组（P<0.05）；观察组患者术后合计并发症发生率低于参照组（P<0.05）。结论微动力系统微创拔牙术联合舒适化干预治疗下颌阻生智齿患者可以缩短手术时间和骨愈合时间，减少术中出血量，减轻疼痛和恐惧情绪，提高患者舒适度，降低并发症发生率。

Objective To investigate the effect of minimally invasive tooth extraction with micro-power system combined with comfort intervention in the treatment of patients with mandibular impacted wisdom teeth. Methods A total of 220 patients with mandibular impacted wisdom teeth were enrolled as research subjects and divided into an observation group and a reference group according to envelope method, with 110 cases in each group. The reference group was treated with traditional tooth extraction, and the observation group received minimally invasive tooth extraction with micro-power system combined with comfortable intervention. The perioperative related indicators (operative time, intraoperative blood loss and bone healing time), pain intensity at 1 week after treatment [visual analogue scale (VAS) score], fear level [children's fear survey schedule-dental subscale (CFSS-DS) score] and comfort level (evaluated by the general comfort questionnaire, including four dimensions: environmental, psychological, physical and sociocultural dimensions) were compared between the two groups, along with the occurrence of postoperative complications. Results The operative time, intraoperative blood loss and bone healing time of observation group were shorter or less than those of the reference group (P<0.05). After treatment, the pain VAS scores and CFSS-DS scores in both groups were lower than those before treatment, and the aforementioned scores in the observation group were lower than those in reference group (P<0.05). After treatment, the scores of environmental, psychological, physical and sociocultural dimensions in both groups were higher than those before treatment, and the scores in the observation group were higher than those in the reference group (P<0.05). The total incidence of postoperative complications in the observation group was lower than that in the reference group (P<0.05). Conclusion Minimally invasive tooth extraction with micro-power system combined with comfort intervention in the treatment of patients with mandibular impacted wisdom teeth can shorten the operative time and bone healing time, reduce intraoperative blood loss, alleviate pain and fear, improve patients' comfort level, and decrease the incidence of postoperative complications.
