摘要: 目的 探讨数字化导板在下颌舌侧后牙区埋伏多生牙拔除中的应用,并评价其效果。方法 选取2020年1月—2020年11月于徐州医科大学附属口腔医院颌面外科病房就诊的双侧下颌舌侧后牙区埋伏多生牙患者10例。采用自身对照方法,试验侧通过数字化定位导板拔除埋伏多生牙。对照侧不使用导板进行常规微创手术。记录导板制作时间、完成手术时间、术后肿胀及疼痛等发生情况。结果 试验组平均手术时间为(19.84±6.52)min,对照组为(31.03±9.68)min,试验组术后的疼痛和肿胀程度明显低于对照组。经统计分析,两组间差异均有统计学意义(P<0.05)。结论 应用数字化定位导板技术拔除埋伏多生牙,可显著缩短手术时间,手术并发症明显减少,提高手术质量,值得临床推广。

Abstract: Objective To investigate the application of digital guide plate in extraction of impacted supernumerary teeth in the lingual region of mandibular posterior region and evaluate its efficacy. Methods From January to November, 2020, 10 patients with bilateral impacted supernumerary teeth in the lingual region of bilateral mandibular posterior region treated in the department of oral and maxillofacial surgery, Affiliated Stomatological Hospital of Xuzhou Medical University were enrolled in this study. By self-contrast method, one side of 10 patients were treated with digital guide plate to remove the impacted supernumerary teeth (test group). The other side which was treated without using guide plate for operation served as the control group. The manufacture time, operation time, postoperative swelling and pain were compared between the two groups. Results The average time of operation was significantly shorter in the test group ((19.84±6.52) min) than in the control group ((31.03±9.68) min), and the degree of postoperative pain and swelling was significantly lower than the control group. Statistics showed that differences between the two groups were statistically significant (P<0.05). Conclusion The application of digital guide plate in extraction of impacted supernumerary teeth in the lingual region of the mandibular posterior region can significantly shorten operation time, reduce surgical complications and improve surgery quality, which has good application prospect.
