摘要： 目的: 探讨3D口腔扫描结合数字化导板在下颌后牙牙列缺损种植中的应用价值。方法: 将2021年3月—2022年10月杭州口腔医院收治的行下颌后牙牙列缺损种植的96例患者随机分为对照组（48例）与试验组（48例）。对照组采用常规种植修复,试验组采用3D口腔扫描结合数字化导板种植修复。比较两组患者的手术相关指标、种植体精准度、种植体稳定性、牙槽嵴顶骨吸收量,统计两组种植成功率、并发症发生率及患者满意度。结果: 两组患者术后疼痛时间和术后肿胀时间相比,差异无统计学意义（P>0.05）,试验组手术时间显著短于对照组（P<0.05）,试验组冠部偏差、根部偏差、深度偏差、角度偏差显著小于对照组（P<0.05）。两组种植成功率、种植体稳定系数比较,差异无统计学意义（P>0.05）。试验组牙槽嵴顶骨吸收量显著低于对照组（P<0.05）,试验组并发症总发生率显著低于对照组（P<0.05）,试验组患者满意度显著高于对照组（P<0.05）。结论: 3D口腔扫描结合数字化导板用于下颌后牙牙列缺损种植,可有效缩短手术时间,提高种植体精准度,减少并发症,提高患者满意度。

Abstract: PURPOSE: To investigate the value of 3D oral scanning combined with digital guide plate in implant restoration of mandibular posterior dentition defect. METHODS: A total of 96 patients with mandibular posterior dentition defects treated in Hangzhou Stomatology Hospital from March 2021 to October 2022 were randomly divided into control group (48 cases) and experimental group (48 cases). The control group was treated with conventional implant repair, while the experimental group was treated with 3D oral scanning combined with digital guide plate implant repair. The operation related indexes, implant accuracy, implant stability, alveolar ridge and parietal bone absorption of the two groups were compared, and the implant success rates, complication rates and patient satisfaction were also evaluated. RESULTS: There was no significant difference in postoperative pain time and swelling time between the two groups(P>0.05), but the surgical time in the experimental group was significantly shorter than that in the control group(P<0.05). The crown deviation, root deviation, depth deviation and angle deviation in the experimental group were significantly smaller than those in the control group(P<0.05). The success rate of the experimental group was significantly higher than that of the control group(P<0.05). There was no statistically significant difference in the planting success rate and stability coefficient between the two groups(P>0.05), and the absorption of alveolar crest bone in the experimental group was significantly lower than that in the control group(P<0.05). The total incidence of complications in the experimental group was significantly lower than that in the control group (P<0.05). The satisfaction of patients in the experimental group was significantly higher than that in the control group(P<0.05). CONCLUSIONS: The application of 3D oral scanning combined with digital guide plate in implant restoration of mandibular posterior dentition defect can effectively shorten the operation time, improve the accuracy of implant, reduce the complications, and improve patients' satisfaction.
