【摘要】 目的分析超声骨刀冠切术在近下牙槽神经阻生智齿拔除中的临床效果。方法 72例近下牙槽神经阻生智齿拔除患者,按照随机的原则分为对照组和实验组,每组36例。对照组采用传统凿骨劈冠术,实验组采用超声骨刀冠切术。比较两组患者的手术时间、疼痛程度评分、术后肿胀程度、张口受限程度及并发症发生率。结果实验组的手术时间(27.82±7.91)min明显短于对照组的(35.28±13.27)min,差异有统计学意义(P<0.05)。术后1、2、3 d,实验组的疼痛程度评分分别为(4.14±0.92)、(2.51±0.83)、(1.34±0.47)分,均明显低于对照组的(6.16±1.32)、(4.57±1.01)、(3.04±0.84)分,差异有统计学意义(P<0.05)。实验组的术后肿胀程度、张口受限程度均明显轻于对照组,差异有统计学意义(P<0.05)。实验组的术后并发症发生率8.33%明显低于对照组的41.67%,差异有统计学意义(P<0.05)。结论在近下牙槽神经阻生智齿拔除中,应用超声骨刀冠切术能让下牙槽神经损伤的发生风险明显降低,术后并发症明显减少,具有比较显著的临床效果,而且能让患者拔牙恐惧症明显减轻,生活质量显著改善,具有临床推广价值。更多还原

【Abstract】 Objective To analyze the clinical effect of ultrasonic osteotome coronectomy in the extraction of impacted wisdom teeth of the proximal inferior alveolar nerve. Methods A total of 72 patients with impacted wisdom teeth of the proximal inferior alveolar nerve were randomly divided into control group and experimental group, with 36 cases in each group. The control group was treated with traditional osteotomy, and the experimental group was treated with ultrasonic coronectomy. Both groups were compared in terms of operation time, pain level score, degree of postoperative swelling, degree of mouth opening and complication rate. Results The operation time(27.82±7.91) min of the experimental group was significantly shorter than(35.28±13.27) min of the control group, and the difference was statistically significant(P<0.05). At 1, 2, and 3 d postoperatively,the pain level scores of the experimental group were(4.14±0.92),(2.51±0.83), and(1.34±0.47) points, which were significantly lower than(6.16±1.32),(4.57±1.01),(3.04±0.84) points of the control group, and the difference was statistically significant(P<0.05). The degree of postoperative swelling and mouth opening of the experimental group were significantly lighter than those of the control group, and the difference was statistically significant(P<0.05). The postoperative complication rate 8.33% of the experimental group was significantly lower than 41.67% of the control group, and the difference was statistically significant(P<0.05). Conclusion In the extraction of the impacted wisdom teeth of the proximal inferior alveolar nerve, the application of ultrasonic osteotome coronectomy can significantly reduce the risk of inferior alveolar nerve injury, significantly reduce the postoperative complications, and has a significant clinical effect. The patient’s fear of tooth extraction is significantly reduced, and the quality of life is significantly improved, which contains the value of clinical promotion.更多还原
